M. Ulinuha As Shiddiqy — Backend + AI Engineer — and smart contracts
[00] — Who
I build backends that hold up — and contracts that have to.
Backend AI engineering intern at FlyRank AI. Freelance full-stack since 2023. On the side: smart contracts in Rust, Solidity and Move, plus the self-hosted infra that runs it all. IT student at Universitas Gadjah Mada.

[03] — Manifesto
I like systems where getting it wrong is expensive — APIs under load, AI pipelines, and money on-chain.
- Spec firstInvariants and edge cases on paper before any code.
- Break it myselfSelf-audited my own Soroban workspace: 2 HIGH + 5 MEDIUM fixed, each with a regression test.
- Own the whole stackAPIs, indexers, SDKs and the servers they run on — my own hardware, my own on-call.
- Still learningThe on-chain work is testnet so far. The tests are there for when it isn’t.
