Full-Stack TypeScript Engineer building scalable SaaS products and startup systems.

I work across backend architecture, API design, database modeling, and modern frontend systems.
Most comfortable in early-stage environments where ownership, speed, and product thinking matter.

• Secure API architecture & authentication flows
• Supabase / Postgres data modeling
• Product infrastructure for early-stage startups
• Automation tools & internal systems
