Summary
👤
Senior🎓
Top SchoolRay Chong is a Senior Software Engineer based in Hong Kong with seven years of experience building high-performance payment, wallet, ledger, and communication systems at scale. He has a track record of designing resilient architectures—leading ledger and payment optimizations at HSBC and pioneering an omnichannel Communication-as-a-Service platform at Lalamove that handled high concurrency and provider fallback logic. At Crypto.com he removed vendor dependencies by building an in-house ledger with full observability and is currently building an AI-native engineering ecosystem that leverages agents for code generation, automated reviews, and knowledge management. Ray combines deep systems-level optimization (CQRS, Kafka, partitioning, virtual threads) with strong developer experience discipline—onboarding docs, runbooks, and engineering narratives—to speed delivery and reduce incidents. He’s comfortable both as a technical lead and hands-on engineer, often refactoring legacy code and upgrading dependencies to harden security. An unconventional strength: he embeds AI into the developer workflow to automate edge-case testing and accelerate feature delivery.
