Work

Dozens of product teams shipped features “as is”: release meant deploy, rollback meant a night-time hotfix and on-call, and feature state was smeared across configs and people’s heads. There was no single way to roll functionality out and off safely.

A centralised platform on Unleash: a single flag store, gradual-rollout and targeting strategies, sticky sessions, change audit and CI/CD integration. Plus an admin interface with role-based access and monitoring — transparent for engineers and managers alike.

Product hypotheses were tested by eye: there was no single way to split traffic, collect metrics reliably and read the result honestly — all without a release per experiment.

Deterministic user bucketing (identifier hashed with a per-experiment salt, sticky sessions), exposure logging, a “variant ↔ metric” link, guardrail metrics and statistical interpretation instead of peeking at charts.

Build a full arcade with no game engine: game loop, enemy AI, collisions and smooth movement — using only React, TypeScript and the Canvas API.

A requestAnimationFrame loop with a fixed simulation step; state kept in a ref to avoid per-frame re-renders; four ghosts with distinct chase strategies; keyboard, swipe and on-screen controls.
