About

Full-stack engineer who likes turning messy problems into reusable systems.

I'm a product-focused full-stack engineer with 3.5+ years building scalable SaaS and healthcare platforms at Docquity, which serves healthcare professionals, patients, and pharma stakeholders across multiple countries. I work across the stack — Angular and React/Next.js on the front, Java/Spring Boot and Node.js on the back.

A theme runs through my work: I like building things once, configurably, so a team can reuse them instead of rebuilding. That's how a legacy Patient Assistance Program became a metadata-driven form engine serving tens of thousands of patients, how onboarding became an installable npm package, and how a pile of one-off surveys became a single configurable platform. When the data calls for it, I'm happy to reach past the relational default — modeling healthcare-professional relationships in Neo4j for reusable, graph-based audience targeting.

I care about end-to-end ownership and the parts users never see: RBAC and secure multi-role access, caching, clean service boundaries, and leaving a codebase easier to extend than I found it.
