I'm Engineer with a rare blend of scalable backend expertise and deep ML experience, helping companies build reliable systems and data-driven products that scale
💪 About Me
I'm a backend engineer who loves building quiet, reliable systems that just work. I have spent years in fintech and data-driven environments designing APIs, automating workflows, and untangling complex problems to make software feel calm and dependable. I care about craftsmanship, clarity, and building things that help people without demanding attention.
When I am not coding, I am usually writing fantasy worlds, sketching maps, or relaxing with retro games. Whether it is a codebase or an imagined kingdom, I enjoy building systems that feel alive and thoughtful.
📋 Experience
At MerQube, I built and scaled core backend systems for index computation, including a billion-row data store, production APIs, automated reporting pipelines, and cost-efficient infrastructure. My focus was on making complex processes simple, reliable, and ready to grow.
At Affirm, I worked as an ML engineer focused on improving risk decisioning through practical, data-driven systems, including merchant risk models, onboarding workflows, and graph-based fraud detection. My work aimed to strengthen trust and reduce losses by making risk assessments more accurate, thoughtful, and resilient
