Eloy Vieira

At Citcoin Exchange, I built and maintained the backend of a cryptocurrency exchange and trading platform. I developed automated spot and P2P trading systems, including a Binance P2P system that validates sell orders, processes PIX payments through an in-house banking API, and completes related crypto transfers and sales.

At Banco Green, I built a PIX banking API used across internal products, including the exchange and automated P2P systems. I also developed services for deposits, withdrawals, payments, refunds, and transaction status updates.

Through Storm, the software development company I founded and continue to operate, I've delivered web platforms, business systems, and mobile applications for clients across different industries. My work has included healthcare systems, a jewelry business platform, marketing tools, and local government applications.

My recent work has focused on fintech and cryptocurrency, including trading platforms, banking APIs, payment systems, and real-time services. I work across backend development and software architecture, using technologies such as Python, PHP, Go, and AWS.
