Hi, I'm Dany 👋

Frontend & mobile engineer from Indonesia (GMT+7). I build web and mobile apps on one React + TypeScript stack — from App Store apps to real-time trading dashboards and Solana dApps.

LinkedIn Portfolio

⛓️ Web3

  • ZiroDelta (Solana dApp) — built the wallet layer (wallet-adapter provider, connection, auth) and the core trading screens of the web app, plus the wallet flows of the React Native app (Phantom, WalletConnect, send/receive).
  • On-chain tooling (private) — Uniswap v3/v4 LP entry on an EVM chain with viem; a Meteora DLMM liquidity bot on Solana.

📱 Web & mobile

  • Flimty (AIMI Group) — in-house mobile & web engineer since 2022. Consumer app plus six internal products (CRM, POS PWA, LMS, Next.js portal, field-sales app).
  • Buddy: Virtual Pet Chat — AI companion app on the App Store (Expo, Firebase, PostHog). 9 App Store releases for a Canadian startup, as part of a two-person team.

🔨 Open source

  • Fragment — project memory for AI coding agents. Decisions, rejected paths and next steps live in the repo, so the next session doesn't ask again. Bash + Git, MIT.
