How We Build
We pick tools that are proven, well-supported, and right for the job. Here's what's in our current stack.
AI & LLM Integration
We help you ship AI-powered features fast - from conversational interfaces and document intelligence to RAG pipelines and function-calling agents, built on Claude, OpenAI, and open-source models.
React Native
Ship native iOS and Android apps from a single codebase. We've delivered polished, production-grade React Native apps across fintech, edtech, and consumer categories.
Next.js Full-Stack Apps
Next.js is our go-to for modern web products - combining fast server rendering, API routes, and seamless deployment on Vercel. From marketing sites to data-heavy SaaS dashboards, it covers the full stack.
Supabase Backend
Supabase gives your product a production-ready Postgres database, auth, real-time subscriptions, and storage out of the box. We use it to get clients to a working backend in days, not weeks.
