Aleksei Trofimov
.NET Tech Lead / Software Architect — Andersen
I’ve been working in software development since 2011, focusing primarily on C#, .NET, ASP.NET Core, backend development, and application architecture. I also have hands-on experience with full-stack development using JavaScript, TypeScript, and React. Over the years, I’ve worked on projects of varying scale — from small applications to large enterprise systems. I’ve been involved in designing and delivering complex solutions from scratch, working as an architect and team lead. I'm experienced with modern technologies and tools, including SQL and NoSQL databases, message brokers, Docker, and cloud platforms such as Azure and AWS. Currently, I work at an international company as an architect and technical lead. Outside of work, I enjoy traveling and skiing, both alpine and cross-country.
