## About

I'm Matheus Lima, a Computer Science graduate from UFCG with 7+ years building web products — from senior frontend work on production platforms to founding and running my own SaaS.

Since 2024 I have built and operated Todas do ENEM, a subscription study platform for Brazil’s national college entrance exam, now used by 742 registered students. In parallel I deliver AI automations and agent integrations as an independent consultant.

I work end to end — product, interface, API, database, billing and deployment — and I have led a team and mentored junior developers.

## FAQ

### What kind of work do you take on?

Complete web products (Next.js frontend plus API, database and billing), AI features on top of an existing product - chatbots, agents, LLM integrations and workflow automation - with design included.

### What is your availability?

Up to 40 hours per week, remote, in a timezone that overlaps with both Europe and the Americas. Get in touch and I will tell you my current lead time.

### What is your working process?

An initial call to understand the goal, then a written scope with milestones. From there I ship in short cycles with a preview environment you can open at any time, so you follow the progress instead of waiting for a reveal at the end.

### Do you handle design as well?

Yes. UI/UX, visual identity and the implementation ship as a single package, which is how most of my client projects are delivered.
