I'm Muhammad Meidy Noor Al-Barry (EndPx), a fullstack developer in Indonesia and a Computer Science student at UPN Veteran Yogyakarta.
I build web and onchain products across interfaces, APIs, data, and smart contracts. My current work focuses on wallet UX, exact accounting, and transaction recovery.
A multichain savings app where progress becomes a 100-piece 3D build. It connects a React PWA, authenticated backend, and Solana/EVM vaults.
Product preview: example account and illustrative balances, not user savings or adoption metrics.
- Engineering focus: isolated goals, cross-chain state coordination, wallet flows, and recovery without blindly replaying transactions.
- Evidence: documented browser-signed testnet deposits, completion, and claims, with original transaction links. The current release uses cash vaults; mainnet and realized yield are outside its scope.
An event platform on Monad testnet: reserve a seat, receive a QR pass, check in, and claim after settlement.
Product preview: the public CommitPass landing page. Testnet execution scope is described below.
- My work: fullstack implementation across Next.js, Go, Neon, Envio indexing, and Solidity contracts, building on the ATFI foundation credited in the repository.
- Engineering focus: contract-controlled funds, host-attested attendance, and indexed application state.
- Status: public testnet settlement and claim evidence; mock yield and CRE CLI broadcast simulation are explicitly separated from production deployment.
A browser car-ball game using TypeScript, Colyseus, Rapier, and Three.js, with server-authoritative physics and synchronized rendering.
A pixel-art editor with 19 WebMCP tools. Human and agent edits share an action layer and undo history, making changes visible and reversible.
- ReFlow: smart-contract and backend engineering for lending-asset tokenization on Mantle, including Ponder indexing and collaboration with ReStock. Champion — Mantle Global Hackathon (Builder Story Spotlight).
- ATFi: fullstack Web3 development for event commitments on Base using ERC-4626, Goldsky, and Morpho. Winner — Base Batches #2.
- Built a village profile website with Express.js and Cloud Firestore, and supported web-development training at ITC UPNVY.
- Frontend: TypeScript, React, Next.js
- Backend & data: Go, Node.js, Express, SQL, Neon, Firestore
- Onchain: Solidity, Foundry, Solana/Anchor, event indexing
- Interactive applications: Three.js, realtime networking, shared state
I make transaction state and recovery paths explicit, keep test evidence separate from production claims, and document what a demo proves and what still needs validation. The project repositories include architecture notes, test instructions, and execution evidence for a closer technical review.
