Experience
Software Developer (Intermediate), Southerly Fintech Ltd

Wellington
- Designed and built a settlement reconciliation service in C# and PostgreSQL that matches 180,000 transactions a day, replacing a spreadsheet process that ran a day behind.
- Cut the p95 response time on the account API from 900 ms to 220 ms by removing two synchronous calls and adding a cache in front of the ledger.
- Set up the team's incident reviews; pages per on-call week fell from eight to two over twelve months.
- Wrote the design note and migration plan for moving four services from EC2 to containers on ECS, delivered with no customer-facing downtime.
Developer, Tui Street Software

Wellington
- Built the online application form and case API in TypeScript and Node for a government client, used by 40,000 applicants in its first year and tested against the NZ Government Web Accessibility Standard.
- Replaced a nightly CSV import with an event-driven pipeline so that case updates reached the client's contact centre in seconds instead of the next morning.
- Added contract tests between three services, catching breaking API changes before release and ending a run of Monday-morning fixes.
