Work

Selected product work

A few product surfaces where I owned the frontend, shaped the interface system, or helped a team keep product quality coherent.

Indie learning product

Drill

getdrill.app

An exam-readiness product that turns study material into measurable proof of what students actually know.

Designed the product around a strict study protocol: short runs, plausible traps, immediate feedback, and mastery states that make readiness visible without motivational noise.

Built the product end to end with optimistic interactions, immediate feedback, calm pacing, and typed frontend systems that keep product complexity understandable.

  • Product strategy
  • Interaction design
  • Optimistic UI

Frontend architecture leadership

BANGK

Led frontend across web, native, investor, and marketing surfaces for an early-stage financial product.

Owned the frontend architecture for web and native product surfaces while keeping interaction patterns, UI standards, and delivery quality aligned across the investor dashboard and public site.

Led a small international team through code review, technical decisions, and day-to-day frontend execution.
