Senior .NET Full-Stack Developer

A little about me

I am a results-driven senior full-stack developer with over 9 years of experience building complex software systems. My career spans ERP platforms, fintech products and core banking solutions — most recently as part of Kara under Sepas Holding, where I work at the intersection of software engineering and the financial industry.

I have a proven track record of designing and implementing systems from the ground up using the architecture best suited to each problem — microservices, event-driven or layered — with a strong focus on performance, reliability and security. I am equally comfortable leading a team, collaborating in Scrum environments, or diving deep into query optimization and system design.
