Building Products That Scale

10+ years engineering fintech platforms, SaaS products, and enterprise systems — with a focus on system reliability, production debugging, and AI-assisted development.

What I Do

Building modern web applications with clean code and thoughtful design

Full-Stack Development

Building modern web applications with Next.js, Express.js, FastAPI, and Spring Boot. End-to-end solutions from database design to polished user interfaces.

Next.js / Express / FastAPI / Spring Boot

API & System Design

Designing scalable APIs and backend architectures for fintech and SaaS. Payment systems, microservices, and clean architecture patterns.

REST / GraphQL / gRPC

Cloud & DevOps

AWS, Azure, Docker, and CI/CD pipelines. Infrastructure as code and automated deployments.

Debugging & Reliability

Systematic root cause analysis, production incident resolution, and AI-assisted debugging workflows to ship stable, well-tested code.
