Software engineer building WellKey, a wellbeing platform shipped to the App Store and Google Play.

United Kingdom
Message

I founded and built WellKey, a B2B employee wellbeing platform, independently. I shipped its mobile app to the App Store and Google Play, and developed anonymous employee check-ins, AI-assisted chat with crisis-language safety guardrails, and an aggregated employer dashboard.

After gathering requirements from HR leaders and conducting discovery interviews, I secured a $22K grant and deployed WellKey on Vercel and Supabase. I also improved its HR and owner panels, added a free-pilot flow, and fixed a Stripe webhook issue so failed events are retried.

At J.P. Morgan, I developed a production financial application used daily by internal teams during a migration to Java, Spring Boot, React, and AWS Aurora PostgreSQL. I worked on React/Redux and Java/Spring functionality for reference-data screens and handled dual-write transactions across legacy and modern databases.

On home4u, I built a data ingestion pipeline for real-estate listings, including crawling, normalization, quality checks, and deduplication, then exposed the data through a public API. I also implemented semantic search using embeddings and Gemini, with validated structured filters.
