Frontend Engineer (React/TypeScript) | DeFi & Web3 Integrations

Active 3 hours ago
🌱 Member since September 2026

I spent 2021-2023 living inside DeFi before I ever wrote production code — reading protocol whitepapers from first principles (starting with Bitcoin), not summaries or influencer takes. I actively managed a diversified crypto portfolio across Ethereum mainnet and L2s (Arbitrum, Optimism, Polygon), provided liquidity, staked for yield, and ran my own risk-monitoring workflows under self-custody (MetaMask/Ledger) — profitably growing that portfolio over the cycle.

In 2024 I turned that domain fluency into software engineering. I'm a frontend engineer specializing in Web3/DeFi integrations — React, TypeScript, and reading on-chain data, not authoring smart contracts.

My flagship project, DeFiScout, is a Uniswap V3 pool analytics and LP strategy simulator: I implemented the concentrated-liquidity math straight from the whitepaper (not the SDK), handled BigInt precision for on-chain values past Number.MAX_SAFE_INTEGER, and replaced 40 sequential REST calls with a single batched TheGraph/GraphQL query.

I don't need a detailed spec or hand-holding — I read the docs, build the thing, and ship it.

Tell us a joke?

The optimist sees the glass as half full. The pessimist sees the glass as half empty. The software architect sees a glass with twice the capacity required by the original specifications. The frontend developer says the glass is ugly and proposes rewriting the whole thing in React.
