You talk directly to the person who writes your code — no agency, no middlemen. I build new backends and repair slow, broken ones: APIs, data pipelines, crawlers, integrations.
From the first message to the last commit, you work with one senior developer. Systems I built process 30M+ products a day — and I bring the same care to your project.
Available for contract work.
Pick the problem that matches yours, or just describe it — I'll tell you where to start.
Slow pages, slow queries, overloaded servers. I find what's slow and make it fast.
New backends, APIs and services built to run in production — not just on your laptop.
Crawling, price monitoring and pipelines that move large amounts of data reliably.
Move off legacy PHP or modernize step by step — without breaking what works.
No sales layer, no project managers relaying messages. You explain the problem once, to the person who will actually solve it.
I've built and run crawlers and pipelines processing 30M+ products daily — systems that must keep working, not demos.
I tell you what needs to be done and what it costs before we start. Fixed scope where possible, no bloated teams, no surprises.
Describe the problem or what you want to build.
I look at the problem and we agree on what needs to be done.
Development, debugging, testing — whatever is needed.
Working code and a system that does what it should.
A few of the production systems behind these services.

Find a job or offer your services.
Built the Go backend — API, matching logic and deployment.
Remote security scanner with ping and certificate checking.
Built the scanning daemon and monitoring backend.
Describe what you need help with. A few lines are enough — I reply personally.
