Miguel Teixeira
Senior Frontend Engineer.
I build AI-powered web products.
20+ years in software engineering. React, TypeScript, and LLMs.
Fully AI-native — I ship production apps end-to-end with Claude Code.
Things I've built
AI-powered web apps I've designed, built, and shipped — each one a real product, not a tutorial project.
Smooshie
AI character chat platform with generated avatars, voice synthesis, and long-term memory. Each character has a unique persona powered by RAG pipelines for persistent context across sessions.
Snarkle
AI-powered social media reply generator. Users pick a tone and platform, and the app crafts contextually appropriate responses using fine-tuned prompts and structured output parsing.
BrawlBeat
AI-driven fan site for Brawl Stars. Generates brawler insights, strategy guides, and character analysis using LLM-powered content generation with game data context.
PartyQuest
AI treasure hunt generator for events. Creates location-aware, themed clue sequences using LLMs with geolocation context and age-appropriate content filtering.
Dancing Heart Yoga
A clean, responsive website I built for my wife's yoga practice. Simple, warm design focused on class information and easy booking.
About me
I've spent 20+ years building software — most of that in frontend engineering for financial services, working with React and TypeScript at scale across complex, regulated environments.
Over the past two years, I've made a deliberate shift into AI-native development. Not as a buzzword — as a genuine change in how I build. I use Claude Code with Atlassian MCP end-to-end across my entire development workflow — from ticket to PR. I've built and shipped 5 real AI-powered web apps in my own time, each one a working product with real users.
I'm genuinely passionate about LLMs and what they unlock for product development. This isn't a career pivot — it's the natural evolution of two decades of engineering experience meeting the most exciting technology shift I've seen.
