About

Technical leader with over 8 years of experience architecting and leading cross-functional teams through the full product lifecycle of fintech platforms. I define technical roadmaps, report to stakeholders and make the key business and technical decisions — while staying hands-on in the code that matters most.

My core stack is PHP 8.3, Symfony, Domain-Driven Design, microservices, Kubernetes and PostgreSQL. Lately I have been integrating large language models into real products — agentic workflows, Claude API and AI-assisted engineering — and I am looking to build and scale a new product for the US market.
