Architected and maintain SuperEmotes—a multi-tool web platform (superemotes.com) that started as a cross-browser emote extension but evolved into a suite of creator utilities serving 400+ unique daily visitors (primarily via high-traffic tools like the Fake Discord Message Maker). Built and host popular web tools including: Fake Discord Message Maker — A generator for custom/prank Discord messages (with ping support, image export, and easy editing), used for content creation, memes, and YouTube/streamer videos. Drives significant daily traffic and engagement. Other featured utilities: Kick Chat Overlay (stream display), Animate Emotes/Emojis, Animated Banner/PFP/Sticker Makers—leveraging Vanilla JS, animations, and dynamic rendering. Core extension development: Chrome/Firefox/Edge/Tampermonkey versions using Vanilla JavaScript, WebExtension APIs—handled CORS/auth challenges for seamless Twitch/YouTube integration. Live on Chrome Web Store, Firefox Add-ons, Edge, etc. Full backend engineering at api.superemotes.com: Java Spring Boot, raw PostgreSQL (JDBC + Apache DBCP2 pooling for concurrency), robust validation/auth, Swagger/OpenAPI docs, and server-side rendering (SSR) for SEO (e.g., user/emote pages). Sustains 80,000+ monthly API requests from real usage. Comprehensive internal platform: Centralized logging (rsyslog + LogAnalyzer), metrics/alerting (Graphite + Grafana), multi-VPC OpenVPN, Gitea + Matrix ChatOps, Jenkins CI/CD, automated backups, one-command AWS provisioning—ensuring reliable, solo-operated production uptime over 5+ years. This hands-on ownership of a live, traffic-generating platform means I deliver fast, practical fixes and small features—from JS bugs and web tool tweaks to Discord generators, animations, or API endpoint, with proven real-user impact.
