A decade of shipping. Reverse-chronological.

Founder / CTO · Falora

Building falora.xyz — English learning for Spanish speakers, taught through short lessons cut from real video instead of drills. The hook is a weekly challenge staked and paid out in WLD: finish the week, get paid. Skill, not luck. Running product and engineering end to end, from the lesson pipeline to the payout rails.

technical detail (6)
  • Built the World App mini-app end to end — onboarding, the video lesson feed, and the weekly stake-to-payout loop.
  • Designed the WLD pot mechanics: stake collection, 200-XP completion checks, and splitting the pot across finishers on a weekly cycle.
  • Shipped live pronunciation scoring over the browser mic, with word-level feedback against the lesson transcript.
  • Built the lesson pipeline that cuts real video into short exercises — transcript alignment, word cards, and six exercise types.
  • Own the Supabase backend: Postgres schema, row-level security over user progress and stakes, and auth tied to World App identity.
  • Shipped the bilingual ES/EN React + Vite landing site and wired PostHog instrumentation across the activation funnel.

Senior Software Engineer · Unbound Nation GmbH

Seed-round Web3 venture. Architected and shipped the rental, renewal, and payment systems plus the EVM asset functionality. Designed the cross-chain UX so the wallet switching disappeared into the transaction flow.

Technical Founder · Catch Labs Pte. Ltd.

Co-founded and led engineering for a Web3 venture. Closed $50k in funding on the back of a first-place finish at the Cardstarter hackathon. Learned more about scoping a startup down than at any job before or since.

Software Engineer · Koppla GmbH

TypeScript / Vue development. Owned the Vue 2.6 → 3.4 migration on a non-trivial product surface — composition API rewrite plus a parallel CI strategy so feature work didn't freeze for the duration.

Software Engineer · Media Markt Saturn GmbH

Shipped checkout and merchandising features that handled the 340M-visit Black Friday spike. Big retail, brutal load tests, plenty of cache-invalidation discipline learned the hard way.
