Frontend developer in Web3 — I build dApp UIs and on-chain data dashboards with Next.js/TypeScript, wagmi/viem, and The Graph. Computer Science & Engineering graduate @ Politehnica Bucharest.
Currently exploring zero-knowledge and DeFi frontends.
| Project | What it is | Stack |
|---|---|---|
| DID Wallet (ZKP) | Self-sovereign identity wallet that proves age, citizenship, and income range with zero-knowledge proofs verified on-chain — never revealing the raw data. | circom · Groth16 · React Native · Solidity |
| DeFi Risk Analyzer (team) | Uniswap v4 hook that raises swap fees as pool depth drops, protecting LPs from toxic flow. I built the swap UI and contract integration. | Solidity · Uniswap v4 · wagmi/viem · Next.js |
| MEV Forensics Agent (team) | An AI agent that investigates why a DEX/MEV trade underperformed and delivers a cited report. I built the entire frontend — a real-time investigation dashboard with an SSE-streamed tool-call timeline, PnL/verdict cards, evidence panels, and shareable permalinks. | Next.js · TypeScript · TailwindCSS · SSE |
| Job Tracker | Production-style job-application tracker: auth-protected dashboard, CRUD, advanced table UX, E2E tested. | Next.js · Prisma · PostgreSQL · Clerk · Playwright |
