Portfolio

Tae Lee

Lead Frontend Engineer

I build interfaces for products with too much data to show at once — dashboards, maps, live feeds, and the tables under them. Four years of it, from a bank to a developer tools startup, where I now lead the frontend. Day to day I work agent-augmented — plan-driven development with Claude Code and Cursor.

Based in Melbourne, Australia

Career

Work Experience

Four years of frontend, in banking and in blockchain infrastructure.

Lead Frontend Engineer

contract.dev

Oct 2025 – Present

Melbourne, Australia (remote)

Own the frontend of the product: the contract map, the contract dashboards, the activity explorer, and the metrics and monitoring screens. Used by around 140 developers watching 3,500 contracts. Most of the work is deciding what a screen says at rest and what it only says when asked. I also co-built the CLI that lets coding agents drive the platform, and built the company’s outbound engine as an agent-run system on top of it.

Observability

contract.dev

2025 – Present

An observability platform for smart contracts. Watch what your contracts are doing in production, get alerted when one moves outside expected conditions, and drill from a month-long trend down to the single call behind it. Stagenets replay mainnet state, so a change can be rehearsed before it ships.
