I’m Saminas Gigar, a software engineer at Muun, building reliable e-commerce products across mobile and web. My work focuses on maintainable software that can evolve with the product, from user-facing applications to the backend services supporting them.

I enjoy understanding how complete systems fit together—applications, APIs, databases, infrastructure, deployment, and observability. The problems I find most interesting usually sit between these areas, where good architecture and practical product decisions matter equally.

Alongside my professional work, I’m pursuing an M.Sc. in Intelligent Adaptive Systems at Universität Hamburg, focusing on machine learning, computer vision, neural networks, robotics, and trustworthy AI. I’m also deepening my experience in Go, cloud infrastructure, distributed systems, and scalable backend architecture.
