At twenty I co-founded an ENT × NFT startup and took the CTO seat. I was the entire backend team — every layer the service stood on, from API design through auth, payments, on-chain integration, and the deploy pipeline, had to be built by one person.
I built the backend on NestJS + Prisma, split the stack into Dev/Stage/Prod, and wired zero-downtime deploys through GitHub Actions. On hard screens I reached into the frontend code myself and carried it to release, and on the NFT side I helped design and build the smart contracts so the chain and the service moved as one.
That work earned a CES 2023 Innovation Award, and our own product hit 3,000 MAU in its first month. Steady, Castme, Fandly — the backend and infra behind all of them still run under one person’s watch.
