The short version

I’m Tan Ji Sheng, an engineer and operator. I studied computer science at Multimedia University and researched deep learning for network-fault prediction through a TM R&D-sponsored Master by Research programme, which I left before the thesis. Across thirteen years of building, the last eight have focused on blockchain infrastructure and applications.

That work included queue-management apps, live bus tracking, and waste-fleet analytics used by two Malaysian local governments. At Trivechain, a public Layer-1, I led development through a proof-of-work upgrade and built the migration to BNB Chain when the original network wound down in 2021. And a full NFT game studio, Playermon, where I progressed from blockchain developer to CEO around September 2021, after completing the smart contract and leading the token-sale promotion campaign. My tenure spanned 2021–2025, and the studio grew to more than 60 people at its peak. The company was acquired; my role ended with that chapter.

Today I’m CEO of GamBit Custody, GamBit Group’s digital-asset custody arm. GamBit Custody is regulated by Securities Commission Malaysia. It’s a fractional mandate, held alongside independent advisory, systems architecture, and fractional-CTO work at the intersection of AI and blockchain. The thread through all of it is that wealth, especially digital wealth, should survive its handovers. There are also small, free, ad-free tools because craft needs an outlet that doesn’t need a pitch deck. Some of it is pro bono, like the interactive blessing panels I built for the Bodhi Temple. My career progression, leadership roles, and education are on the Experience page.
