Chalid Ade Rahman.
Senior Frontend Engineer.

8+ years building production web apps for global teams across EdTech, logistics and fintech. I architect and ship React / Next.js applications that scale — TypeScript-first, with full-stack range across Laravel and Node.js — and AI-assisted (agentic) development is a core part of how I work every day. My deep-work hours overlap European afternoons and US Pacific mornings.

Things I'm proud of

EdTech SaaS · The KPI Institute (AU)

Lerero v2 — White-label LMS & Course Marketplace

A ground-up redesign of Lerero, The KPI Institute's multi-tenant learning platform: training providers build courses from ~25 interactive activity types (quizzes, proctored assessments, SCORM, instructor-led sessions, games, learning reinforcement), sell them through a companion storefront with Stripe checkout, and run it all under their own brand and domain. Started as a team effort; after the team was downsized I carried the frontend to production as the sole frontend engineer.

VWO — Virtual World Job Fair

A job fair you walk through as a character: company stands, live seminars, HR calls and a company portal. Payments run on an append-only coin ledger with idempotency keys and per-user locks, and movement is sent as intent so a crowd fits a free realtime tier. Built with Claude Code; I set the scope and constraints and reviewed every PR.
