ABOUT ME

Serial Coder - haven't stopped since the 90s!

Full-stack engineer and fractional CTO with 10+ years shipping production systems, improving architectures, and unblocking teams. I thrive in early-stage environments where speed and technical ownership matter.

My work spans TypeScript/Node, React/React Native, AWS, and backend platforms built around clean domain models, secure-by-default APIs, and observable event-driven workflows.

I’m focused on helping teams ship faster, scale reliably, and build compliance-friendly systems that stay predictable under real-world load.

- Designed and delivered a POC feature for Pro SG, modernising an architecture I first built ~8 years ago. - Reused a configuration-driven forms engine (JSON-defined wizards with runtime rule evaluation) to avoid hard-coded flows and keep discovery fast. - Updated the design for the current stack and delivery expectations, prioritising maintainability, speed of change, and clean separation of business rules from app code. - Led the technical direction end-to-end, from shaping the solution to guiding implementation and ensuring the POC was credible and extensible beyond the demo. - Worked closely with stakeholders to turn evolving requirements into a flexible, data-driven workflow that can change without constant code rewrites.

Speedoc is an Uber-for-x style application that serves as a house-call platform for doctors and patients. - MVP featured an Uber-style booking interface with a live view of a doctor's ETA on a map. - MVP supported managing dependants (elderly patients and children). - MVP included medical history, iPad doctor entries, and prescription data. - Admin portal supported doctor sign-ups (patients downloaded the app directly). Speedoc eventually went through a Series C funding round of $5m three years later.
