AI Web Scraping Platform
Redesigning the workflow setup wizard for an AI-powered data platform serving investment analysts. I owned the product from research to React/TypeScript implementation — cutting setup steps by 50%, removing 3K lines while adding features, and learning that familiar UX wins when users are under pressure.

AI Developer Tools
GUIs to APIs from popular and emergent AI & SaaS platforms enabling builders to automate their workflows. I cofounded a startup building apps relied on daily by 3500+ businesses like IDEO, Alteryx, and Toptal.

Realtime Asset Tracking
An IoT-enabled console for Supply Chain Managers to coordinate terrestrial operations. I built the first prototype, and rapid design-testing program — identifying 2 critical flaws, and deprioritising 1 feature, reclaiming 4 weeks of dev time we reinvested into validated user needs.

Live Transit Planner
A ux refresh of the city’s official journey-planning app (serving ~250K daily commuters) plus building a new smart feature. I led the end-to-end design from audit to release, focusing on glanceable decision support, built on an extensible design system needing minimal dev lift.

Urban Experience Discovery
A smart city exploration app helping travelers and curious locals discover authentic food spots, neighborhood events, and offbeat experiences. I designed the city's first official app with 200K downloads, and 4.3 App Store rating in the first 6 months.
