About me

I'm Ilya, a software engineer and co-founder/CTO based in Warsaw, and I build the kind of systems most people only read about — not toy demos, but production software with real users, real data, and real constraints.

Right now I'm CTO of NudgeLink, an AI-powered B2B SaaS platform for LinkedIn outreach and SDR automation, running on FastAPI, PostgreSQL with pgvector, Celery, Redis, and the Claude API. Alongside that, I'm working as a security engineer helping a medical company in Belarus architect and harden an internal system handling sensitive personal and medical data — encryption, anonymization, logging, and regulatory compliance from the ground up.

That mix is typical of how I work: I move fluidly between building AI-driven products, backend infrastructure, and security engineering, and I've done it as a founder, a freelancer (via Malt and freelancermap), and a hands-on builder — from a Django personal finance app to a cross-exchange crypto arbitrage bot to a legal-tech LLM pipeline for patent litig
