About
I’m a frontend Tech Lead and Senior Software Engineer with 7+ years of experience building and modernizing React and TypeScript products across fintech and SaaS environments. I lead architecture and delivery decisions hands-on, ship features end-to-end, and enjoy simplifying complex codebases through pragmatic refactoring and scalable system design.
I also bring strong full-stack depth (C#/.NET with BFF patterns), and I’m passionate about engineering growth—mentoring, running interviews, and creating predictable delivery processes. Whether I’m introducing GraphQL, improving performance, automating API client generation in CI/CD, or adding monitoring and alerting in production, my goal is to help teams move faster while delivering reliable, maintainable software.
