About this gig

Need a full stack app or an AI-powered platform built by someone who has shipped real production systems?


I'm Carlos, a Software Engineer with 3+ years building SaaS platforms, payment infrastructure and AI agent systems.


What I've built professionally:

  • A multi-provider payment gateway with a unified abstraction layer
  • A remittance engine handling 9,000+ monthly transactions
  • A multi-agent AI platform with tool calling, MCP servers and attribute-based access control
  • 10+ domain microservices, including omnichannel support chat


What you receive:

  • Fully working app: frontend + backend + database
  • Complete source code, 100% yours, from the Basic package
  • Clean architecture and documentation
  • Dockerized delivery, deployable to any provider
