I design and build secure, scalable, production-grade backend systems. I combine strong architectural thinking with modern engineering workflows to deliver reliable software with speed and precision.
I specialize in making deliberate architectural decisions that result in maintainable, secure, and truly reliable software in real production environments — currently deepening my expertise in Go for high-performance systems.

TypeScript Next.js Supabase
- 🏗️ Architecture is a deliberate decision — hexagonal/clean boundaries between domain logic and infrastructure
- 🔒 Security is a design constraint from day one, not a layer added at the end
- 💥 Systems are built to fail safely — idempotency, retries, dead-letter queues, observability
- 📝 Documentation and honest retrospectives are part of the deliverable, not an afterthought
