Strengths

Strong senior full-stack and platform-architecture — comfortable across modern (TypeScript, Node, React, AWS, Python) and legacy (PHP, Java) stacks, with deep AWS, cloud infrastructure, and scaling experience. Effective at modernising legacy systems while continuing to deliver business features. Hands-on Tech Lead style — leading teams through architecture decisions and code review while still shipping daily. AI / LLM integration capability (Claude, OpenAI, RAG, vector search). Quick to onboard and deliver in unfamiliar codebases.

Interested in working involving

Looking for fractional CTO or senior contract work — open to part-time, project-based, or longer engagements. Sydney-based, remote-friendly, available immediately.

Most recently spent 22 months as senior backend dev at a Sydney fintech, building a TypeScript /Fastify / AWS Lambda microservice for entity management and KYC end-to-end, while also maintaining and modernising a legacy custom PHP monolith (including a long-deferred PHP 5.6 → 8.2 upgrade). — which gave me strong Australian financial domain knowledge across KYC / AML and entity structures, ASIC.
