Full-stack TypeScript engineer at WestPoint Software Solutions who built an analytics dashboard that cut reporting to minutes.

Message

At WestPoint Software Solutions, I progressed from junior frontend developer to full-stack engineer, shipping features from design through deployment for Commonplace, a UK-based SaaS client acquired by Zencity.

I architected an analytics dashboard platform from scratch with Node.js, GraphQL, React, and PostgreSQL. Its filtering, charts, CSV export, and AI ingestion replaced a manual, ticket-based reporting workflow and cut report turnaround from 1–2 business days to minutes.

I re-architected backend and database performance ahead of scale, delivering up to 10x faster page loads and API responses. I also built and operated production APIs and helped meet a 99.9% uptime SLA.

After the acquisition, I led a zero-downtime migration of Commonplace’s data and features onto Zencity’s platform. In shorter projects, I delivered a React Native marketplace with a web dashboard and a Chrome browser extension.
