About

I'm a senior full-stack engineer with 9+ years building scalable, secure backend systems and shipping AI-powered product features. I work across Go, Node/TypeScript, and Svelte/React — spanning fintech, e-commerce, legal-tech, and logistics.

Right now I'm hardening enterprise warehouse and delivery platforms for Australian-market rollout — OAuth2, AWS, Terraform, resilience patterns, and observability. I also integrate LLMs into production: retrieval-augmented search, Anthropic/OpenAI API features, and agentic workflows with Claude Code.

I'm based in the Philippines and work concurrent US and Australian engagements, covering both AEST and US business hours. Open to relocation — AU, CA, DE/EU, US, SG.
