Backend Engineer at PTGR AG building fintech services and APIs for a crypto remittance platform.

Ethiopia

Message

At PTGR AG, I design and develop fintech backend services using Go and TypeScript. I built REST APIs in a microservice architecture for production workloads and optimized PostgreSQL queries.

On PTGR Pay Gateway, I engineered backend services for international crypto remittances, including transaction orchestration, wallet operations, and settlement workflows.

Earlier, I built backend APIs and ERP modules at Techsphere and Go Digital Technology, and developed Telegram bot platforms supporting over 10,000 active users at Blih Intelligent Ops. I also developed Carra Market, a digital marketplace combining e-commerce and raffle-based purchasing.
