Full-Stack Developer focused on backend architecture, security, and scalable systems.
My GitHub documents a self-taught journey from small learning experiments to production-grade engineering systems.

Philosophy

I learn by building repeatedly.

Many repositories in this profile represent iterations of the same systems and ideas — authentication, backend architecture, frontend scalability, deployment workflows, and operational reliability.

Rather than hiding earlier work, I keep the progression visible because it reflects how my engineering thinking evolved over time.

Engineering Focus

Backend Architecture
Modular monolith design · RBAC systems · queue workers & async processing · caching strategies · transactional safety · API design · system reliability

Security
JWT rotation · CSRF protection · rate limiting · input validation · secure authentication flows · token blacklisting

Frontend Systems
React · Next.js App Router · TypeScript · state management · scalable frontend architecture

Infrastructure & Testing
Docker · GitHub Actions · Vitest · Playwright · Prometheus · CI/CD workflows

Current Focus

Consistency · testing · maintainability · security · long-term system design
