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.

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

Worked across two phases: MVP launch and scaling/security hardening.

• Launched full-stack MVP in 1 month
• Architected Supabase schema (auth, relational models, storage)
• Integrated wallet authentication & tokenization flow
• Migrated production data from Airtable to Supabase
• Hardened critical endpoints to mitigate injection risks
• Built internal admin tools and campaign automation systems
• Implemented infrastructure for campaign execution workflows

Contributed to production templates and platform stability.

• Built and maintained Next.js templates
• Worked with Drizzle ORM and Turso database
• Fixed critical bugs and improved rendering reliability
• Contributed to production-ready frontend/backend integrations

• Clean architecture over hacks
• Security and maintainability matter
• Build products, not demos
• Own outcomes, not just tickets
