iGaming front-end and full-stack lead, casino and sportsbook. I've shipped end to end since the late '90s; today I lead Bitsler's front-end and design team, after building product at FanDuel and PokerStars with Flutter. Hands-on engineering with a strong design sense, very much at home building the in-house tools and dashboards that turn dense data into gorgeous, usable screens.

Experience

Bitsler/Front-End Development Lead

iGaming · crypto casino & sportsbook · Full-time

  • Lead Bitsler's front-end team (6 engineers and 2 designers) and own the player-facing crypto & fiat casino and sportsbook UI - hiring, code review and roadmap with the owners.
  • Rebuilt the platform from Vue 2 to Vue 3 with server-side rendering (TypeScript, Node), on AWS behind Cloudflare - cutting load times, lowering bounce and lifting SEO; work that helped drive a 20% rise in first-time deposits.
  • Created the Super Pixel Series - the first three of a planned dozen Pixi.js casino games, self-initiated and now live.
  • Created Thumbnail Manager - an in-browser tool the art team uses daily to design, batch, export and publish artwork across the 12,000+ games we host, saving hundreds of manual hours.
  • Designed and built the new backoffice end to end - Vue 3/TypeScript, PHP, MySQL: finance, CRM, player management, analytics.
  • Brought AI into the team's daily work and mentored the devs into it - Claude in our repos, automated tickets, and AI analysis of player, churn and finance data.
