Backend Engineer
Building Production-Grade Systems
Full-stack developer with 4+ years of experience specializing in backend engineering. I design and build scalable APIs, real-time systems, and secure payment architectures.
Engineering systems that scale
I don't just write code — I architect solutions that handle real-world complexity.

Payment Integrations
I'm a full-stack developer who thinks in systems, not just screens. With 4+ years of experience shipping production software across e-commerce, fintech, real estate, and marketplace platforms, I focus on building architecture that scales.
My work centers on designing secure REST APIs, implementing payment flows with escrow logic, building real-time communication systems, and deploying cloud infrastructure that stays online. I write code that other engineers can maintain and businesses can depend on.
When I take on a project, I think about database modeling, authentication security, transaction integrity, monitoring, and performance — not just making things look right, but making them work right under load.
