I Build Backend Systems
That Scale.

Production Backend Engineer · API Architect · System Builder

2+ years building production-grade backend systems, scalable REST APIs, and cloud-deployed applications for startups and growing companies. Specialized in Node.js, TypeScript, PostgreSQL, and AWS.

About Me

I'm a backend-focused software engineer with 2+ years of production experience building systems that businesses depend on daily.

My work centers on three principles:

→
Reliability — Architecting systems with proper error handling, logging, and monitoring so they run without constant intervention.
→
Scalability — Designing database schemas, API layers, and service architectures that handle growing user bases without rewrites.
→
Clean Architecture — Writing maintainable code with clear separation of concerns, proper testing, and documentation that lets teams move fast.

I've shipped authentication systems, payment integrations, real-time data pipelines, and REST APIs serving production workloads. I work across the full stack when needed, but my deepest expertise is in backend infrastructure.
