About this gig

Have an AI product idea and need someone to build the whole app, not just call an API? I design and deliver AI-powered apps end to end: the interface, the backend, the LLM layer and the deployment.


I'm an AI engineer with 8 years building critical products. I start by turning your idea into a clear scope and an honest estimate, then deliver on time.


What I build:

- AI web apps and SaaS with React and Next.js: chat, copilots, smart search, document Q&A

- AI mobile apps for iOS and Android with React Native

- AI desktop apps with Electron

- Node.js/TypeScript (NestJS) backends with PostgreSQL and vector search

- Streaming responses, auth, usage limits and admin panels


How I work:

- A written scope and milestones before any code

- Early demos, so you see the AI working from the first week

- Clean, typed code your future team can maintain

- Deployment on AWS or GCP with CI/CD


Send me your idea before ordering, and I'll recommend the right package or a custom offer.

AI engineer and fractional CTO. I build production AI products: agents, RAG, LLM integrations and MCP servers, on the solid engineering that critical products demand. 8 years shipping software, including high-stakes platforms at XP, Banco Modal and LiveOn BaaS. I turn vague AI ideas into clear scope, honest estimates and on-time delivery, and I cover the whole stack around the model: Node.js/NestJS, PostgreSQL, React/Next.js, React Native, Electron, AWS/GCP with CI/CD and Docker, and OWASP security. I've led teams of up to 7 engineers as a technical PO.
