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?

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. So we are going to give away some coupons for free access to IDE of your choice for a whole year.

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

“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?

DevOps Salaries in Hungary: A Quick Update 💼 Over the past two weeks, the DevOps job market in Hungary has remained steady. If you're at a Junior level, finding a job might be challenging. Across popular platforms like NoFluffJobs and Profession, I only came across one listing from NIX. However, if you're a Mid or Senior level professional, you’ve got plenty of options to choose from! The market is brimming with opportunities tailored to different preferences and skill sets. In the category of top-paying remote positions (especially in the crypto space), here are the standout roles: Platforms Engineer: 12,500 EUR SRE: 17,349 EUR #job #salary #salaryDevOps

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

If you are curious on "Evolutionary Architecture" don't miss our .NET User Group Zürich May Meetup where we will cover the topic providing some lessons that diverge from "pure tech" talks. On this one, Maciej Jedrzejewski will explain How incremental developments in core engineering have enabled the foundations for enable software which can evolve over time along the architecture, protecting important architectural characteristics as it evolves. All while keeping it as simple as possible, maintainable and manageable in amount of complexity. Sounds interesting? ;) It is!! And even more if you have 5+ years of experience, chances are that you have lived a project that died because of complexity and lack of proper architectural vision (partial or... complete) - I've been there! So, how does it sound and all of this - for free!! Thanks Digitec Galaxus AG and Maciej Jedrzejewski!!! I am not going to miss it - and so should you... RSVP while you can, places are limited: https://lnkd.in/dmnnEGUZ Ah, we will have Food & Drink #architecture #software #evolutionaryarchitecture #KISS #DRY #easy #maintainable #resilience

I got a question yesterday at Devoxx Poland as to why I describe the APIs proposed by JEP 453 (Structured Concurrency) [1] as "low-level", compared to Ox [2], which I'd call a "high-level" structured concurrency API. I think this might be a common concern, hence a wider explanation on my part: First of all, there's nothing wrong with being "low-level". The proposed #Java APIs are more flexible, but they are also more verbose and error-prone. It's a tradeoff, which makes total sense for a JDK API. I'm viewing the JDK APIs as "foundational". That is, not necessarily for consumption by end-programmers, but as a basic toolkit, which library authors (such as myself, in Ox), can use to implement a structured concurrency library. Very similar to reactive streams: we have the base `Publisher`/`Subscriber` APIs in the JDK, but they are targeted to be implemented by library authors, not application developers. (cntd in the comments)

Another expert in the DevOpsDays Warsaw team is Andrzej Grzesik. ags loves distributed systems in all shapes and forms. He has written software in many languages and continuously finds JVM his favourite platform. He believes „most software problems are people problems”, so he stirs communities (Polish JUG), organizes and speaks at conferences (proud to be a JavaOne Rockstar!).
