Software engineer with 10 years of experience, with a background in the retail domain and SaaS application development, complemented by expertise in payment systems and user management platforms. I began my career as a .NET backend developer and transitioned into full-stack development using Node.js, React, and AWS, building scalable distributed systems. In recent years, I've led engineering teams of 3-6 developers, driving both feature delivery and architectural decisions. I most recently led the end-to-end development of a new application, from team recruitment and MVP planning to successful production launch. I've also led performance and scalability initiatives across multiple teams, achieving up to 95% reduction in execution time through architectural optimization, caching strategies, and system profiling.
