I have been building full-stack web applications for 5 years, working across startups and SaaS products using React, TypeScript, Node.js, NestJS, and PostgreSQL. I have delivered production-grade features at SRED.io (a Canada-based compliance SaaS) and previously at Vernasoft, where I also mentored junior developers and built reusable component libraries. What sets me apart is my ability to own problems end-to-end from architecting backend APIs to shipping polished UIs while communicating transparently with clients throughout. I am looking for long-term freelance engagements where I can contribute meaningfully to product teams building real-world SaaS, AI-first, or marketplace platforms.
