Hey, I'm Andrey Surzh — software engineer.
The era of solo developers has arrived. — Hire freelance full-stack developer, Go, React, AI-assisted MVP development, Cyprus
While agencies assemble 15-person teams and schedule their third alignment meeting — I've already shipped your MVP. Got an idea or a spec for a product? Send it over, let's talk.
The world has changed.
Claude &
Codex write code now.So why hire an engineer?
Accountability
AI is a powerful, fast, but irresponsible workforce. I use AI as a tool, but I own everything it produces as if I wrote it myself. My responsibility is that the software works and does what your business needs.
Architecture Is Still Not an AI Task
Claude generates functions and modules brilliantly. But decisions about service boundaries, data structure, scaling, and future bottlenecks require a full understanding of the system. That context can't be passed in a prompt. Architecture remains an engineering task.
AI Does Exactly What You Ask
It'll write thousands of lines of code in minutes. But it amplifies the quality of the task you give it. Well-defined task → great system. Poorly defined task → a problem built at speed. An engineer is needed to point AI's power in the right direction.
Software Needs Maintenance and Evolution
A system has to survive months and years of change. New requirements, integrations, load, edge cases. Code needs to evolve without the system turning into chaos. An engineer builds it so it can grow — not get rewritten every six months.
Two Modes I Work In
Custom Software for Your Business
Web applications that solve your company's specific problem. Not Salesforce you'll spend six months configuring — a system that works exactly the way you need it to.

Projects I Can Show
Unfortunately, many great projects are hidden behind NDAs. But here are the ones I can talk about.

2025RAG Support Platform
2025A customer support platform using RAG — Retrieval-Augmented Generation. The client is a battery supplier for vehicles, caravans, boats, and yachts. They had a problem: over 5 years, about 20,000 support tickets had piled up in Zendesk, and the questions kept getting more complex.
The problem
Imagine a customer asking: "Can I charge two batteries with different amperage together using the company's original charger?" That's not a FAQ question. That requires knowing product specs, compatibility matrices, charging protocols. Previously, a support agent would spend 15-20 minutes digging through documentation and past tickets to give an accurate answer.
What I built
I imported the entire Zendesk database as question-answer pairs. Every resolved ticket became training data. The system uses Qdrant as a vector database — when a new question comes in, it finds semantically similar past tickets and their answers, then uses a language model to generate a precise response based on that context.
The RAG approach
RAG is the right tool here because the knowledge is very specific and constantly evolving. You can't just fine-tune a model once and forget about it — new products launch, specs change, edge cases appear. With RAG, the knowledge base stays fresh. New resolved tickets automatically become available for future answers.
The result
Response time dropped dramatically. What used to take a support agent 15 minutes now takes seconds. The support team went from 3 people to 1 — the remaining person handles edge cases and validates the AI's answers on tricky questions.
