Brice C.

Sole engineer on a Twitch Bits–monetized streaming extension, I own the product end-to-end: Laravel API, two Vue 3 frontends, and a live-stream overlay renderer — with integrations spanning ElevenLabs (AI audio), FFmpeg (waveform scoring), and Twitch pub/sub to broadcast events to live viewers in real time. In parallel, I led the dashboard and onboarding redesign on Nuxt 4 / Vue 3: defining the free-vs-pro gating model, the quota-exhaustion upgrade flow, and the subscription-cancellation rewrite — all shipped behind a unified i18n layer across 5 locales. On performance and reliability: cut hot-path latency across ~25 API endpoints (composite indexes, response and JWT-decode caching, restructuring an N+1-adjacent EXISTS subquery), designed Redis-backed global and per-user cooldowns to protect downstream services from abuse, migrated alert timeouts to a service worker to survive browser power-saving throttling, and resolved an auth race condition via user-store hydration. Finally, drove design-system consistency across ~25 components by migrating hardcoded Tailwind values to named tokens, with CI enforcement to prevent regression.

SoundAlerts is the most-used extension in the Twitch ecosystem, a monetization platform serving ~2M monthly creators with alerts, overlays, sound effects, and a design marketplace. Over four years, I owned the dashboard and the live-stream overlay renderer, the two streamer-facing surfaces of the product. I designed and shipped the Scene Editor from scratch: an in-browser WYSIWYG canvas where streamers compose their live-stream overlays from 12+ draggable widgets (alerts, chat, leaderboards, goal bars, media, timers…), with multi-axis snapping, per-widget schemas, and real-time mock-event playback for in-editor testing. I also built the alert-animation editor (browser WYSIWYG with embedded CodeMirror custom-CSS support, draggable layer tree, in/out animation library) and the streamer-facing design marketplace it feeds, backed by a Firebase Cloud Functions email moderation pipeline. Earlier on, I rebuilt the v2 dashboard from the ground up: redesigned alerts/events system, overhauled data management, shipped to the full user base without service disruption. On reliability, I owned the OBS browser-source runtime that renders alerts on streamers' overlays: automated Twitch token refresh via Firebase callbacks, fixed memory leaks in long-running video alerts, hardened pipelines against user-input injection, and pinned Sentry to v7 to preserve compatibility with OBS's embedded Chromium 68 webview. I co-led the platform's modernization across both apps with zero customer downtime — Vue 2 → Vue 3, Vuex → Pinia, Vue CLI → Vite, Firebase v8 → v10, and Vuelidate → Zod — each unblocking the next layer of product work. Also bootstrapped the Storybook 8 component library and public docs site the team built against.
