The slides for EDA Day Warsaw 2024 and my talk are ready, but it's super hard and sad to me that I won't be able to be there with you at EDA Day Warsaw 2024. It's one of those moments where I must put aside my dreams, goals, and ambitions and be with my family. There is also good news for the community, as I have a fantastic replacement! Eric Johnson is coming to the stage, and that's great news for the community! :) If you know Eric, then you know that this means a lot of laughs, interesting topics, and a fantastic atmosphere. He is a top-class speaker! If you are interested in my presentation - I will record it or present it online. Hopefully, it will be presented online during the #believeinserverless event meeting because I would love to discuss the content presented with the community. I feel that it's a huge missed opportunity to discuss it in real life with so many brilliant EDA experts in Warsaw, but hey - that's life. In case you really can be there but haven't planned to (yet), check that incredible lineup: https://lnkd.in/dH6fGYr6 and think about it again! :) There are few opportunities to meet all those fantastic speakers in real life in one place in Poland: Anahit Pogosova Alex DeBrie David Anderson 🚀 🚀 David Boyne Emily Shea Eric Johnson Filip Pýrek 🍬 Gillian Armstrong James Eastham Joshua Kahn Michael Gasch Natasha Wright Oskar Dudycz Vadym Kazulkin Don't forget to use the promo code 'm&s10' for a 10% discount on your ticket.

Quick engineering salary comparison based on the #DEVBG stats from 2023 and 2024 in the Bulgarian IT industry. Dev.bg publish yearly a summary of the Bulgarian IT engineering salaries based on the job openings offers on their platform. https://lnkd.in/dNU5MD8D (2023 stats) https://lnkd.in/dX_dxvP7 (2024 stats) Based on the population data (let's assume it's a proper representation of the real world) we can determine the following: 1. PHP should be dead but it isn't (unfortunately) as it's one of the two categories with growing salaries in all job positions and ranges. 2. The second is the full stack development with a minimum drop of 65 levas in the first MID range(2-5 years) 3. All ranges except the Senior level(5+ years of experience) have a drop in salary compared to 2023 but for some seem negligible compared to the notion in the industry that "it's going down and AI will take over the world" :) 4. We can see that seniority still counts and there is now a shift towards growth of salaries of more senior people compared to others as the market tries to regulate. 5. There is still a lot of green for a "dying" and "shrinking" industry. P.S To anyone interested I can share the excel if needed but it's quite straightforward to generate it. *Legend: Diff min Mid - difference in the minimum ranges for a category between 2023 and 2024 Diff max Mid - difference in the maximum ranges for a category between 2023 and 2024 Diff min Sen - difference in the minimum ranges for a category between 2023 and 2024 Diff max Sen - difference in the maximum ranges for a category between 2023 and 2024 Diff min Sen Median - difference in the minimum ranges based on the provided median from dev.bg for a category between 2023 and 2024 Diff max Sen Median - difference in the maximum ranges based on the provided median from dev.bg for a category between 2023 and 2024

Next AWS User Group Wrocław meetup in a week (24.04.2024). 📅 24.04.2024 ⌚ 18:00 📍 Wędrówki Pub: https://lnkd.in/eeYukrXZ First of all, thank you ALGOTEQUE Innovation Hub for sponsoring our event! :) 🎤 Speakers: 🔭 Marcin Sodkiewicz (me) I am going to talk about #opentelemetry in my talk titled "Observability on AWS & OpenTelemetry". It's talk on the 300 level, but don't worry, I am going to cover all areas, and even if you are new to a whole concept I think you should understand everything. This is also a great opportunity to discuss your experiences with #opentelemetry. 📟 Grzegorz Kalwig: "Serverless is above limits? Our Path to production database cluster" If you don't know about it - Grzegorz is on a road tour with that talk as I believe I saw that he presented that material in many User Groups already. It means that his material is polished and he should be able to answer all your questions about Aurora Serverless v2. Super interesting and important topic, so stop by and make notes :) We are still part of JetBrains Community Support program.

Do you hire developers based on technical skills alone? It could be costing you.  Many companies make this mistake, believing that if a developer can code well, they’ll automatically thrive in the team. But this is not always the case. I have a client in Krakow who specifically hires Java Engineers who can have a “normal conversation" about software, clean code practices, and general life. But most importantly someone he can get along with. If they can do that, he’s usually ready to hire them. However, if they don’t fit culturally, it doesn’t matter if they’ve coded at Google, have an Oxbridge education, or have a long list of technical achievements. They won’t get the job. This is also not unique. According to Leaders.com, approximately 80% of employers take personality into account when making hiring decisions. Also research from Harvard Business Review found that 40-60% of hiring managers admit to hiring candidates who resemble them in terms of background, values, or attitudes. None of this mentions their skills. The ability to mesh with the team and collaborate is non-negotiable. Some people picture developers as introverted hackers, coding away in dark rooms, surrounded by empty energy drink cans. The stereotype that developers don’t need social skills in my opinion, comes from how they’re portrayed in Hollywood (Die Hard 4 was what came to mind when writing this). In reality, developers are part of cross-functional teams. They interact with product managers, designers, and other stakeholders daily. They need to explain complex ideas, collaborate on solutions, and contribute to the team’s overall culture. A developer who can’t work well with others or communicate effectively can disrupt workflows, no matter how technically gifted they are. It’s like having the most advanced software that no one knows how to use. What’s the point? The best hires are those who fit into your culture and can contribute to the team dynamic - not just those who can write the cleanest code. So if you’re only hiring based on technical skills, you might be missing out on your most valuable assets: collaboration, communication, and cultural fit. Skills get you in the door, but culture fit keeps you there. Do you take culture fit into account when hiring engineers?  #SoftwareEngineering #PolandTech #TechRecruitment #PolandJobs #CultureFit #DeveloperLife #WorkplaceCulture #TechRecruitment

So much for the basement-dwelling programmer stereotype 😉. Conferences like the International PHP Conference are splendid opportunities to gain new perspectives - and face new challenges. 🛠️ Programming is essentially about solving problems, and events just like this conference allow us to share experiences and learn from best of the best in the industry. During sessions and workshops, I got to hear real stories about real problems - how they arise, how to solve them - and how to prevent them from reoccurring. 😉 I had the pleasure of attending talks on the latest trends in PHP, code optimization and best practices in system architecture. I learned how to avoid common mistakes and what techniques to use to make our applications even more efficient and secure. 🖥️🔐 Meeting other specialists - once again - proved that exchanging insights is the key to growth. I'm glad I could be part of this inspiring community! 🤝✨ Thank you to all the speakers and participants for the incredible knowledge and motivation! 🙏📚 Topics covered: - PHP Core & Optimization [Bohuslav Šimek, Carsten Windler] - Refactoring [Ralf Eggert] - Testing, Test Driven Development, and Logging [Florian Engelhardt] - Software Architecture & Design Driven Development [Katy Ereira, Dr. Sönke J. Magnussen] - Security 🔒 - DevOps & Deployment [Nic Wortel] - Clean Code [Ondřej Mirtes] - Git Advanced & Working with abandoned Open Source Projects [Juliette Reinders Folmer]

Four years ago, I placed a top C#/.NET Engineer in Krakow - and lost my client in the process. At first, everything seemed ideal. The developer was perfect technically, Immediately Available And joined within 10 days of submission. The client was thrilled, and it felt like a win for everyone involved. But then their first day arrived, and everything began to unravel. The candidate clashed with the team's approach, Criticising the code quality, the tech stack, And even the team itself - demanding they were replaced. Within two months, the client dismissed the candidate and ended our partnership. This left the client frustrated and me reflecting on where it all went wrong. Looking back, I realised there were two clear red flags during the qualification process that I had chosen to ignore... The candidate admitted to getting frustrated when others disagreed with their views. They also mentioned frequent clashes with managers in previous roles. This wasn't qualified further at the time. These warnings were overlooked because the rest of their profile seemed perfect. That mistake cost the client valuable time and resources, and I lost their trust. Since then, I have made it a rule. Even if there is a one percent chance that something feels off it needs to be addressed. This principle has helped me build stronger partnerships and avoid mismatches entirely. Since then, I have contributed to €millions in billings and earned the trust of many clients. As agencies, we're paid well for our expertise and judgment it is our responsibility to get it right. The takeaway? Always qualify. Never overlook red flags. Have you ever overlooked a red flag during hiring? What did you learn from the experience? Share your thoughts in the comments.

After my last presentations about AWS & OpenTelemetry at AWS Community Day Poland and after the last AWS User Group Wrocław meetup, I got lost of questions about my slides. I am not sure if they are valuable without my commentary. I was planning to record a voiceover, but I'm not sure if that would be a bit weird as presenting on stage is a bit different than presenting online. Nevertheless there you go :) #aws #awscommunity #opentelemetry #o11y

Hi, today I heard in one podcast, that it's important to build your personal brand in the internet and linkedin is simple way to do it. Honestly, when I was going recently to the inteviews, my first thing to check was the interviewers' profiles on linkedin, so probably it's true ;) I gave a thought, what I could share and concluded, that I read quite a lot of books (listen to audiobooks usually more often), so maybe this could be a nice platform to share this and get also from you counterproposal to the positions, I'll be posting. Feel invited and let's start! For today Polish title, which I personally value as the most comprehensive introduction to Agile (and probably the best as well): #AgileKtóryDziała by Tomasz Borowiec and Michał Dusiński. It covers areas of Agile as a way of thinking, Scrum and Kanban in a way, that everyone will understand. It's short, funny, inspiring and extremely educating. I recommend it, even if you have Agile experience, as I also had it and still got a lot out of it. And you, do you have such recommended positions? https://lnkd.in/gJEzXUPB -

“When Polish software engineers look for a job, they only care about their rate. How can we compete with higher paying competitors?” A client asked me this yesterday. While it’s not entirely true, it’s worth exploring. Do all engineers focus only on rates? No. Is the rate you offer important? Yes - but it’s not the only factor. Here are 4 ways to make your vacancy stand out (even if you’re not the highest paying): 1. Share Your Vision Explain where your business is heading and how the candidate fits in. When candidates see themselves in your story, the role becomes more appealing. 2. Build a Personal Brand for Your Leaders Candidates want to know who they’ll work with. Encourage your leadership team to share their views on technical topics. This helps candidates understand their style and values. It may deter some, but it’ll attract the right fit. 3. Be Transparent About Salary & Perks Don’t make candidates guess. Transparency builds trust. Worried about overpaying? You have the final say. Hiding salaries might cost you great candidates before they apply. 4. Offer a Low-Commitment Introductory Call Let candidates ask questions without starting a formal interview. This lowers pressure for those passively exploring roles. It builds trust and relationships. Even if they’re not ready now, they’ll return when they are. Focusing on the whole package, not just pay, helps you stand out. What’s worked for you when attracting top talent? How do you stand out from the competition?

On May 8th, we have WarsawJS Meetup #114 awaiting us, featuring Tomasz Ducin on stage with a fascinating presentation titled "Back in the game: Recent Revolutionary Changes in Angular"! But today, let's reminisce about his previous appearance at WarsawJS Meetup #108 💭 In that lecture, titled "Who needs Server Components?", Tomasz delved into the next step in the evolution of web architecture. After MPAs, SPAs, SSR, SSG/ISG, it's time for Server Components! Throughout the presentation, he asked himself many questions: Does this architecture fit the needs of my business and application? What are the benefits? And are we not stepping backward by moving more operations back to the server? Breaking down the hype around Server Components, Tomasz also introduced us to some technical details regarding React Server Components. By combining client-side interactivity with server-side efficiency, we can optimize web metrics and revolutionize website development. We invite you to watch that presentation, which opened our minds to a new perspective on web development! Enjoy watching! 🍿 🎥 Part 1: https://lnkd.in/dQ7G_jFZ  🎥 Part 2: https://lnkd.in/dJzQmsQD We encourage you to participate in WarsawJS Meetup #114, where you'll have the opportunity to not only listen to Tomasz's lecture but also to other outstanding speakers live. The link to tickets is below: 👇 🔖 Tickets: https://lnkd.in/dhXVXwpf #WarsawJS #Meetup #ServerComponents #WebDevelopment

In the last couple of weeks, I have had many conversations with Krzysztof Przekwas and Artemi Krauczanka about the critical values of Software craftsmanship. For me: - Code should be simple and readable for all seniors and newbies in the project. - When unnecessary, try to avoid complicated patterns; maybe Kafka or MediatR is an overkill for your project. - You may have a tiny domain, or you built a simple integration to connect two systems, so it is stateless, mainly integration via REST API on the left and right site. - Remember there is a development phase and maintenance - is your code ready to be maintained? Thank you, Isaac Abraham, for the slide on the presentation (and also for the presentation about Functional Programming on .NET - The Best of Both Worlds https://lnkd.in/eiwzFUZe) PS> As a side note, I'm also in the phase of my career to merge services to optimize cost or remove a lot of unused code from the projects, and you?
