Worked as an early engineer for a startup, I led the end-to-end architecture and development of our core software products. I spearheaded the full-stack implementation using Next.js and Supabase, while establishing a robust CI/CD pipeline via GitHub and Vercel.

I deliver complex platforms including a modern CRM with collaboration and realtime analytics, as well as various integrations of third-party services and AI-driven features. This work occurs in a fast-changing environment with frequent direction shifts, requiring strong adaptability and close collaboration with the founder.
