01 — About
Full-stack development, delivered end to end.
I'm a full-stack developer with 4+ years of experience helping companies design, build and launch scalable web & mobile applications. My work spans enterprise finance portals, real-time trading platforms and consumer mobile apps — across Angular and React front-ends, Node.js back-ends, and Flutter.
I care about the things that make software worth paying for: clean architecture, real performance, and the details that make a product feel fast and reliable — from database schema to the last pixel. Work with me and you get clear communication, honest timelines, and code your team can build on.
