Вот Description копируй целиком:


Are you building a crypto exchange, payment gateway, DeFi protocol, or fintech platform? You've found the right developer.

I'm a senior engineer with 10+ years building production-grade financial systems. I've personally architected crypto payment infrastructure handling millions in monthly volume, and implemented regulatory compliance systems for EU and UAE financial frameworks.

What I build:

  • Crypto payment gateways and exchange backends
  • REST and GraphQL APIs in any language
  • Smart contracts in Solidity and Rust
  • DeFi protocols and AMM integrations
  • Fintech compliance and AML/KYC engines
  • AI automation and trading bots
  • Microservices with Docker/Kubernetes

Stack: Python, Go, Node.js, TypeScript, Rust, Solidity, PostgreSQL, Redis, MongoDB, AWS, GCP

I don't just write code I understand the business and regulatory environment it operates in. That means fewer revisions, faster delivery, and a system that actually works in production.

Every delivery includes clean code, documentation, and deployment support
