What I'm looking for

I’m looking to build production-grade APIs and full-stack features with strong security, clean architecture, and measurable quality. I want a team that values ownership, thorough testing, and practical growth in engineering craft.

I’m a backend-focused full-stack developer with hands-on experience building production-grade REST APIs using Node.js, Express.js, TypeScript, and PostgreSQL with Prisma ORM. I prioritize clean architecture, type safety, and security best practices, and I enjoy building features that are reliable under real-world constraints.

In my full-stack monorepo project, Beggy, I built a secure Express.js REST API with modular service→controller→route structure, structured logging with Pino, Swagger/OpenAPI documentation, and comprehensive unit/integration testing with Vitest and Supertest. I implemented authentication and security end-to-end—JWT access/refresh rotation, Google/Facebook OAuth via Passport.js, CSRF protection, RBAC with CASL, rate limiting, and strong password handling—while also supporting the frontend with Next.js, React, RTK Query, and CASL-powered conditional rendering.
