Full-stack work on an insurance underwriting platform, with a Go and PostgreSQL back end and a React and TypeScript front end. Around 250 merged pull requests in eleven months, across authorisation, claims, sanctions, policy endorsements, accounts and the team’s CI and tooling.

• Replaced the platform’s OpenFGA authorisation with an RBAC/ABAC system in Go and PostgreSQL, then led the migration away from identity-provider-managed permissions and the security hardening that followed review.
• Built the standalone claims module and the sanctions change-management system end to end, from API to UI.
• Fixed premium, discount, exchange-rate and contra errors in bordereaux and aged-debt reporting, where small mistakes become real money.
• Removed recurring CI flakes, sped up the integration suite by running serial tests in parallel, and hardened CI by pinning third-party actions and removing persisted credentials.
• Built developer and on-call tooling: one-command local setup, test-data seeding, UAT data cloning, and read-only support integrations.

Back-end development for internal engineering teams, replacing critical systems that had outgrown themselves.

• Rewrote one of the critical systems for managing Sky’s ISP infrastructure: a combined inventory-management and network-configuration system first written 15 years earlier.
• Redesigned and standardised its database and wrote the scripts that migrated the old data across. Strict validation on the new structure let other systems integrate with it cleanly.

Ran part of the college’s Linux infrastructure and its Git and CI/CD processes, and built applications and microservices used across the college.

• Rewrote the student and staff account-management system from PHP in Go. Its hourly sync went from up to 25 minutes to about 17 seconds, most of that the database read, and tighter Active Directory integration stopped the data drifting.
• Introduced Kubernetes and Docker in place of many outdated Linux servers.
• Rebuilt the college’s CI/CD processes almost from scratch.

Developed and maintained the college intranet and a range of standalone internal systems.

• Modernised a large share of the college’s internal systems, many of them more than ten times faster afterwards.
• Built the system that collects and processes pay claims from part-time staff.

Designed, built and maintained the company’s data-management system on my own: a Java server and desktop client, a MySQL database and a PHP website.
