@johnngai

Senior Staff Engineer at OKX working on enterprise AI platforms, model routing, access controls, and multi-cloud operations.

What I'm looking for

I'm seeking remote part-time, freelance, or contract work alongside my current role. I'm available on Hong Kong weekday evenings and flexible on weekends, with a maximum of 40 hours per week across all clients; scope and client allocation can be agreed.

At OKX, I work on enterprise AI platforms, including model integration and routing, access controls, observability, multi-cloud operations, and incident response. Before that, at Fano Labs, I worked on enterprise AI, NLP, voice, microservices, LLM integration, and proof-of-concept work for financial institutions.

At Wesinx, I worked across technical architecture, delivery, data and AI platforms, and DevOps/CI/CD. I also built TechMart, a personal Next.js and TypeScript e-commerce example with Prisma, GitHub authentication through NextAuth, Stripe checkout, and Sentry monitoring.
