Ivaylo Blazhev, founder
I have been building software for 18 years, in corporations and in startups, remote and on site. The work has been energy, industrial operations, fintech, medical software, music distribution and payments.
I started Blazhev Software to do that work for clients abroad as a small company, with the same person designing the system and writing the code. Since 2025 most of that work has had a model in it: agents that build and review software, a harness with a sandboxed runtime, retrieval over regulated documents, and the guardrails that make a fast, cheap model safe to let loose on a codebase.
MSc in Computer Systems and Technologies, Technical University of Sofia. I work in English and Bulgarian.
How we work
Small on purpose, so the person you talk to is the person who builds.
A small team
You work with the people who build the software, not with an account manager.
Senior hands on the code
The person who designs the system writes a good part of it and reviews the rest.
Honest about limits
If something cannot be built well, or not for that budget, you hear it before work starts.
We use what we sell
Our agents, harness and guardrails built Keepwork and rewrote a back office before we offered them to anyone. The articles show the measurements.
And Keepwork
Keepwork is our own product: a private, self-hosted app builder for teams without developers. It is also the harness we built first. Its planner, its sandboxed runtime and its benchmark are where the methods we offer were worked out, and it keeps the same habit as the client work: build the plain, dependable thing and say clearly what it cannot do.
Let's talk
Thirty minutes about what you need built. No preparation, no obligation.
