I design and improve production backends across APIs, third-party integrations, payment workflows, data synchronization, and mature codebases. My deepest stack is PHP and Laravel, with production experience in Node.js and TypeScript. Working remotely with Australian, New Zealand, and UK clients since 2021.
Selected work
Case studies on CRM fault isolation, payment concurrency, and data migration.
Production / Jun 2025 - Present
SoftwareSeni / Funraisin · Full-stack Engineer
Worked across payment correctness and backend feature delivery in a mature fundraising platform, covering intelligent giving, regular giving, matched giving, raffles, Stripe flows, scheduled jobs, Salesforce synchronization, and ticketing.
Added concurrency controls around matched-giving and raffle sales, protecting shared payment state when requests arrive at the same time.
Production / Oct 2022 - May 2025
SoftwareSeni / Reapit · Backend Engineer
Led reliability and modernization work across the Leadplus microservices, covering adapter controls, webhook recovery, identity resolution, REAXML, direct-to-R2 uploads, and compatibility for the Laravel and PHP upgrades.
Provider failures became observable and recoverable, attachment traffic moved off the application servers, and self-healing checks removed some cases that previously needed a developer.
Five assignments, one continuing role — Funraisin, Leadplus, and more.
