Hi there 👋 I'm SEMER NUR, a Backend Engineer and Team Lead working in the FinTech industry. I spend most of my time architecting and building systems that power secure, scalable, and high-performance financial services.
Beyond writing clean and efficient code, I actively support my team—reviewing code, mentoring developers, and ensuring our systems are robust and ready for real-world challenges. My core expertise lies in PHP and Laravel, but I also work across a range of technologies to deliver reliable and future-proof solutions.
Chapa is one of the leading payment gateways in the Ethiopian market, playing a key role in the country's digital payment landscape. It's also the first African payment gateway to integrate Telegram Payments — a milestone I had a major role in delivering. At Chapa, I focus on building and scaling core backend systems, while also contributing to innovative integrations that push the boundaries of fintech in Africa.
Chapagram is a versatile Telegram bot designed to facilitate seamless peer-to-peer payments, remittances, and engaging lucky draw games—all within the Telegram platform. I led the project from start to finish, handling everything from initial development and backend architecture to deployment and ongoing maintenance.
Tikus is a popular SuperApp in the Ethiopian market with over 100K+ downloads on the Play Store. I developed the core backend logic for the app, which offers a wide range of features including social networking, short-form vertical videos, video streaming, a marketplace, and more—designed to provide an all-in-one experience for users.
I developed a system that automates the submission of guest information to the Spanish government (SESHospedajes) to ensure legal compliance for hospitality businesses.
