WHAT I DO

Services.

I take the whole product, or slot into your team where it hurts — from database schema to shipped interface.

01

Software Development

Web apps, SaaS, dashboards, extensions and PWAs — from database schema to interface.

  • APIs and business logic in Node.js and TypeScript
  • React and Next.js front-ends wired to real data
  • Auth, permissions and payments
  • Data modelling in PostgreSQL and Supabase
  • Docker and Vercel deployment, with CI

  • Official WhatsApp Cloud API, no workarounds
  • PIX billing and reconciliation
  • Spreadsheet, CRM and database in sync
  • Alerts, retries and logs on every run

AI & LLMs

Agents that classify, extract, generate and decide — with RAG and multi-agent orchestration.

  • Classification and structured data extraction
  • RAG over the client's knowledge base
  • Multi-agent orchestration with LangGraph and MCP
  • Evaluation: the agent is measured, not just demoed
  • Guardrails, per-call cost and fallback

API Integrations

Connecting systems never meant to talk to each other — and keeping the conversation alive.

  • Meta APIs: WhatsApp, Instagram and Graph
  • Official public registries, including CNPJ
  • Payment gateways and PIX
  • Signed webhooks, queueing and replay
  • Documentation and a test environment included
