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.
CRM for forensic expertise · Affiliate marketing tracking · Custom accounting systems
Technical Co-founder for Your Startup
I've launched startups — and some of them took off. I'll own the entire technical side: architecture, development, deployment, scaling.

NtripCaster — GNSS Correction Server
2016Surveyors on construction sites, cadastral engineers, and even unmanned tractors all need GPS coordinates with centimeter accuracy. Standard GPS gives you maybe 2-3 meters — useless for precision work. NtripCaster is a server that streams correction data from base stations to rovers in the field, making centimeter-level positioning possible.

How NTRIP works
There are fixed base stations with known coordinates. They compare their known position to what the GPS satellites report and compute the error. NtripCaster collects these corrections and streams them in real time to any device in the field that connects via the NTRIP protocol.


The result: a surveyor's receiver goes from 2-meter accuracy to 2-centimeter accuracy. That's the difference between "somewhere in this parking lot" and "this exact bolt on this exact pipe."
What I built
The server handles multiple base stations, manages user authentication, monitors connection quality, and streams correction data with minimal latency. The admin panel shows who's connected, data throughput per station, and system health.


The protocol itself (NTRIP) is a standard in the geodesy world — basically HTTP streaming with a specific binary payload. The challenge was making it reliable and fast enough for real-time field work where every millisecond of delay means reduced accuracy.
