Full-Stack TypeScript Engineer | Backend & Data Systems

Global financial services company — loyalty & rewards platform team

Contributed to a large-scale loyalty platform modernisation and data migration programme, reconciling legacy membership rewards data against a newly architected system during a live migration. Worked directly with a Postgres-backed reconciliation pipeline and used Databricks to process and validate high-volume records, tracing discrepancies across member profiles, points accrual, and partner integrations. Built a Next.js/React front-end for an internal dashboard giving engineers and operations real-time visibility into reconciliation status. Developed and consumed REST APIs on Java and Spring Boot within a microservices architecture and wrote JUnit tests for reconciliation and transformation logic.

Digital product studio / web agency

Acted as primary technical point of contact across client accounts end to end, working directly in each client's existing codebase and constraints. Designed and shipped responsive client web applications, and introduced internal tooling and automated pricing workflows that cut quoting time for new clients. Implemented WooCommerce solutions, including payment gateways and shipping configuration for live e-commerce clients, where failures had direct revenue impact.

Independent practice — multiple concurrent client accounts

Ongoing independent engineering practice, run concurrently alongside full-time and contract roles. Own the full client lifecycle — scoping, onboarding, delivery, and ongoing support — as sole technical point of contact across multiple accounts, each on a different stack. Design, build, and deploy full-stack applications using Node.js, TypeScript, Next.js, React.js, Postgres, and AWS DynamoDB, regularly working in unfamiliar or inherited codebases under client deadlines. Diagnose and resolve live production issues post-launch. Delivered an average 40% increase in client sales within six months of launch and a 60% improvement in online presence across accounts.
