Experience

Senior Flutter Developer

JB Connect LTD · Dhaka, Bangladesh
  • Sole mobile architect for V+ing, a Japanese B2B video recruitment platform serving 30+ hiring companies on iOS and Android
  • Cut video feed load time 75% (4s → <1s) by engineering a two-layer video system: a serialized operation queue preventing race conditions, and a sliding-window pre-fetch cache that warms controllers before they're visible — eliminating the leading cause of user drop-off
  • Reduced release cycle from 2 hours to 15 minutes (87% faster) by establishing multi-flavor CI/CD (GitHub Actions + Codemagic) with a terminal-triggered build script, removing all manual deployment risk
  • Designed MVVM + BLoC hybrid architecture with GetIt DI, go_router, and a Repository facade over REST and Firebase — adopted as the standard mobile pattern across the org
  • Extracted video playback logic into safe_video_player, an internal reusable package running in 2 production apps
  • Owned all Flutter tooling and package decisions; conducted code reviews, authored technical specs, and mentored junior developers
