What I'm looking for

I’m looking to build scalable fintech systems end to end, own architecture and secure integrations, and ship production-ready features that improve credit, risk, and decisioning for real banking customers.

I’m a Senior Software Engineer and full-stack specialist focused on fintech platforms, enterprise integrations, and mission-critical financial workflows. I build multi-tenant banking systems, implement AI/ML-powered financial analytics, and design scalable solutions for credit facilities and loan management—delivering production-ready software for major banks and enterprise clients.

At Quantum Technology PLC, I lead frontend architecture for a multi-tenant digital lending platform built with Next.js and TypeScript, supporting multiple major Ethiopian banks within a single codebase. I also engineered a production credit scoring engine using Django and PMML, containerized the stack with Docker, and built analytics and reporting experiences for portfolio risk and merchant performance.

I’m hands-on across the stack: I designed RBAC and a reusable UI component library to ensure secure data isolation and consistent fintech product UX. In prior roles, I developed ERP integration work, ML payment prediction and forecasting features, real-time financial calculation engines, and automated OCR-based statement processing—while also leading a web development team to deliver scalable digital solutions.
