About

Engineer by craft, product-minded by instinct.

I care about the details that make software feel fast, trustworthy, and effortless — from the first paint to the last edge case.

I’m a results-driven software engineer who loves turning ambiguous problems into clean, fast, production-grade products. I work across the stack — crafting polished React/Next.js interfaces, designing resilient Node APIs, and wiring up real-time and AI-powered workflows.

Recently I built Sledge, an AI operating system for the construction industry — engineering the AI document parser, backend services, and automated contract & project generation that replace hours of manual office work.

Along the way I’ve shipped multi-vendor e-commerce and healthcare platforms, mentored bootcamp developers, led a Microsoft student community chapter, and earned recognition as an MLSA Alpha Ambassador and Headstarter SWE Fellow.
