How I work

ENGINEERED, NOT IMPROVISED.

Clear scope, honest timelines, and code built to last. You work directly with the developer and always know what's being built.

Services

WHAT I BUILD.

01

Web & Mobile Development

Custom web and mobile apps, from MVP to production. If you can describe it, I can build it.

02

Payment Integration

Stripe, Mercado Pago, and Asaas in your product: checkout, subscriptions, payment splitting, and webhooks that hold up.

03

AI & MCP Integration

Features powered by OpenAI, Claude, and Gemini, plus MCP servers that connect your systems to the models — from idea to shipped feature.

04

Automation

Cut the repetitive work that drains your team: data syncing, reports, document and case workflows, real-time alerts — including legal automation with the Judit API across 90+ Brazilian courts.

05

Marketing Websites

Fast, SEO-ready sites wired into your marketing tooling. Built to be found and to convert.

06

Technical Consulting

Support for founders, product teams, and vibecoders. I review, advise, and unblock your project — no coding knowledge required.

TELL ME ABOUT YOUR PROJECT.

A new product, a specific integration, or a stalled project — work directly with the developer who builds it.
