Specialist landing pages
Direct access to vetted independent specialists, stack-specific task breakdowns, and transparent hourly rates.
Most directories only let you filter by programming language, which assumes you already know which language your problem needs. That is rarely true if you are not a developer yourself. So this category is organised four different ways, and you can enter from whichever one matches what you actually know.
Every profile here is an individual engineer. You talk to the person who will write the code, you agree scope with them directly, and there is no account manager translating between you.
That matters for the size of work most people actually have. A three-week integration or a broken checkout does not need a delivery team, a discovery phase and a statement of work. It needs one experienced person with a few free days.
It also changes the price. Agency rates carry the cost of sales, management and bench time. Working directly with an independent engineer removes all three.
A profile is only published after we have checked commercial history, looked at real production code the person has shipped, and confirmed they can explain their architectural decisions in a language a non-technical client understands.
That last part is not decoration. The most common reason a small software project fails is not technical incompetence — it is that the client and the developer never shared the same picture of what was being built.
Use the form instead of the categories. Describe the situation the way you would describe it to a friend: what you have, what is wrong with it, and what you want to be true when it is done. That is enough.
You will get back a plain-language reading of what the work involves, a realistic range for how long it takes, and a shortlist of people who have done that specific thing before. No commitment, and no call with a salesperson.
Yes. Give us the address of the site or a description of what it does, and we will work out the stack. Most clients do not know, and they are not expected to.
Yes. A large share of the work booked through ProofDevs is a single fixed task — a broken integration, a migration, one feature. There is no minimum engagement.
Describe your task or paste your requirements. ProofDevs will analyze your needs and match the most relevant engineers.
