Smart Contract Engineer — Soroban, Solidity, Move
Information Technology student at Universitas Gadjah Mada who writes smart contracts in three languages — Rust on Soroban, Solidity on EVM, Move on Sui — and the backend systems around them: indexers, APIs, and the deployments that keep them running.
About Me
Get to know me better - my journey, passion, and what drives me as a developer.
Hello there! 👋
I'm an Information Technology student at Universitas Gadjah Mada. Most of my work is smart contracts and the infrastructure around them — I like problems where the money is on-chain, the guarantees have to be provable, and getting it wrong is expensive.
I write contracts across three ecosystems. On Stellar: a solo-authored workspace of eleven Soroban contracts for fractionalising real-world assets, plus a yield vault. On EVM: the Solidity behind a prediction market on Monad and a five-contract territory game on Celo, both mine end to end. On Sui: Move packages for a verifiable data marketplace and an autonomous agent wallet, including a reusable delegated-authority session-key primitive. Around all of it I build the off-chain half — RPC indexers, a published TypeScript SDK, and x402 pay-per-use in USDC.

Experience
3+ Years Coding
Current Focus
Currently focused on smart contract security — I self-audited my own Soroban workspace and remediated two HIGH and five MEDIUM findings, each with its own regression test — plus the backend AI systems and self-hosted infrastructure I run alongside it. Everything on-chain so far is testnet; nothing has gone to mainnet yet.

Smart Contract Engineer (Soroban)
Tove Heritage
Sole author of the Stellar contract layer for a real-world-asset platform: eleven Soroban contracts covering a SEP-41 fraction token, a book-build offering escrow, a passkey smart wallet, KYC gating, and gated upgradeability. Nine deployed to testnet with USDC settlement, 220 tests, and CI that verifies canonical WASM determinism. Self-audited the workspace and remediated two HIGH and five MEDIUM findings.
