Dare T.

I build backend systems for crypto and fintech products, wallet integrations, P2P exchange systems, payment flows, and the infrastructure that handles them safely at scale. I have 5+ years of production backend experience across crypto payments, P2P trading systems, real estate AI, and IoT device systems. I work using Go, Python, and TypeScript. What I can build for you - P2P exchange systems with escrow, ledger tracking, and payment lifecycle management - Wallet and payment integrations for crypto and fintech products - Backend systems that handle many users at the same time, with monitoring so issues are caught early - WhatsApp and Telegram bots connected to AI models, including wallet/payment flows - AI agents that use tools, search your documents, and answer customers - Microservice systems split into separate services that communicate through events and queues - Deployment with Docker, plus logging and monitoring I'm available for long-term and retainer engagements, not just one-off tasks, if you need ongoing backend support for a crypto or fintech product, that's the kind of work I do. How I work - I ask questions first, so I build what you need and not what I assumed. - You get working versions early and can give feedback as we go. - I explain decisions in plain language, so you don't need a technical background. Send me a message here on upwork with a short description of what you need, and I'll tell you how I'd build it and roughly how long it would take.
