Senior Full-Stack Engineer specializing in Web3 and FinTech

Global, Remote6y exp

“Full-stack engineer with deep startup experience (pre-seed through IPO/SPAC) currently building a Next.js/TypeScript SaaS sports analytics platform with a complex Postgres-based entitlement/ACL system. Has delivered measurable UX/business impact (35% retention lift, 40% volume increase) and built production-grade daily ETL + model training/inference workflows with validation and checkpointing for reliability.”

“Unity VR developer who built "instructor tools" for a skydiving/canopy training simulator, including comfort-focused wind/landing assessment features to reduce motion sickness. Implemented the simulator’s full Photon PUN networking and added Agora-based video streaming so instructors could run sessions with participants joining from browsers/tablets, while managing real-world latency constraints.”

Senior Unity Game Developer specializing in multiplayer, AR/VR, and Web3 games

Kuala Lumpur, Malaysia9y exp

“Unity/VR developer who has shipped multiple Meta Quest titles, including a Meta Quest 3 VR heritage app backed by the Malaysian Tourism Commission. Built a complex MMO metaverse game end-to-end solo (Photon Fusion 2 multiplayer, 21x13km world, procedural biomes, combat/inventory) with blockchain/NFT integration (Solana/BSC) and AWS hosting, and actively uses AI tools to accelerate prototyping and internal tooling.”

“Project lead who restored a 1999 vintage museum robotics exhibit by inventorying and integrating legacy systems, reverse engineering original behavior, and reimplementing it in a modern codebase. Notably optimized Tesseract OCR and machine-vision pipelines to run on a 400MHz Pentium III with 256MB RAM while bringing up and tuning degraded FireWire IIDC cameras using scarce legacy documentation.”

“Backend-focused full-stack engineer with strong React/TypeScript depth who has owned end-to-end features spanning PostgreSQL, .NET 8 APIs, real-time React dashboards, and production monitoring. Notably built a geofencing tracking module for construction SaaS and a 0→1 secure LAN file transfer engine, combining security-first architecture with measurable outcomes like 40% lower battery usage and zero security breaches in pilot.”

“Unity developer with hands-on Meta Quest XR experience building a radiography/X-ray training proof-of-concept and deep expertise in performance and large-world optimization. Built a bus simulator largely solo, implementing modular vehicle systems, localized traffic AI, multiplayer, and low-end device optimizations. Also develops internal AI tooling (auto-documentation and an AI UI generator) to speed up prototyping and reduce boilerplate.”
