What I'm looking for

I'm looking to build reliable full-stack products where correctness, performance, and resilient transaction design matter. I value hands-on engineering ownership, modern web and platform work, and teams that use strong testing and AI-assisted development practices.

I build full-stack systems where correctness matters, from property settlement for PEXA Australia to billing enrollment at Atmail. I’ve delivered server-side validation, idempotent payment flows, and resilient data pipelines for regulated and transactional products.

At Atmail, I own activation and billing enrollment, built a customer dashboard serving 10,000+ users, and migrated a React app to Remix SSR, reducing initial load time by 40%. I also architected a five-plus-package TurboRepo monorepo, improved CI/CD efficiency by 30%, and remediated a stored XSS vulnerability.

I’ve also built multi-tenant restaurant POS, sports betting analytics, and HRIS platforms using React, React Native, Node.js, GraphQL, PostgreSQL, Redis, and AWS. I enjoy designing systems that stay dependable through duplicate submissions, offline operation, malformed data, and real-world operational failure modes.
