I design and build multi-tenant SaaS platforms and scalable web applications from database architecture to production deployment.

My work centers around NestJS, Next.js, PostgreSQL, and AWS. Whether it's implementing strict tenant isolation (RLS) or handling complex billing via Stripe, I build systems where performance, reliability, and long-term maintainability are critical.
