Hi there! 👋
I’m Sergio, a full-stack software engineer based in the United Kingdom. I like building AI-powered products and production-ready systems end-to-end, with a focus on real-time experiences and clean UX.
These days I'm focused on:
- React + TypeScript (clean UI, strong UX)
- Real-time apps (Firebase, LiveKit, WebSockets)
- AI-powered products (voice + LLM workflows)
- Cloud & DevOps (AWS, Kubernetes/EKS, Terraform, CI/CD)
Some stuff I built:
- Chatify — Real-time chat app with Firebase (Auth/Firestore/Storage): 1:1 + groups, replies, reactions, uploads, themes.
- Interview Coach — AI mock interview platform with real-time voice (Python + LiveKit backend, Next.js frontend).
- Hydration Tracker — Multilingual hydration tracker with weather-based recommendations, reminders, and a dark UI.
- Netflix Clone — Netflix-style browsing with Firebase auth, TMDB integration, watchlist, and trailer playback.
- Kubernetes Microservices Platform on AWS EKS — Production-ready microservices platform with Terraform, Helm, autoscaling, monitoring, and CI/CD.
- TypeRush — Typing practice app with real-time WPM/accuracy feedback and performance summaries.
- XO Rumble — Emoji Tic-Tac-Toe with single-player bots (easy/hard), local multiplayer, and animations.
- Global Weather Visualization — Interactive browser visualization of global weather conditions.
