// about

I build systems that don't break.

I'm a Senior Software Engineer at Siemens Technologies and Services, with a career that started in full-stack development and grew into leading backend architecture for real-time financial systems.

My stack has always centered on Python & Django for the server, React for the client, and AWS for everything in between. I care about more than correctness — I care about throughput, observability, and systems that are still maintainable two years from now.

I've built trading infrastructure handling 10K+ req/sec, integrated broker platforms across three providers, shipped payment stacks with 99.9% success rates, and led teams of 5 engineers to ship faster without sacrificing quality.

"I approach engineering problems the way a backend system should handle requests: methodically, at scale, with zero unhandled exceptions."
