Full Stack Software Engineer specializing in .NET, C#, SQL Server—building reliable RESTful APIs and data-driven systems.
What I'm looking for
I’m a results-driven Full Stack Software Engineer with 4+ years of professional experience focused on .NET technologies, C#, and SQL Server. I build high-performance RESTful APIs while keeping codebases clean, maintainable, and aligned with SOLID, DDD, and modern testing practices. I’m especially proud of improving reliability by tackling complex backend bottlenecks and optimizing database performance in large-scale corporate environments.
In my recent role, I lead the development and maintenance of planning and allocation management systems using ASP.NET Core, and I optimize SQL Server queries for high-performance processing and reporting. I design secure enterprise services, enforce Clean Code standards through code reviews, and use CI/CD and monitoring tools (including Kibana) to support 99.9% system uptime. I also document complex API contracts and technical specifications so teams can move faster with clear, actionable guidance.
I enjoy collaborating across the software development life cycle—debugging, feature implementation, and participating in architectural planning for new modules—while staying hands-on with practical engineering workflows like Git branching/merging for high-traffic production systems. Beyond traditional development, I actively explore Generative AI for visual content creation (with prompt engineering and iterative refinement) and I’m interested in training LLMs to enhance software engineering workflows, especially automated coding assistants and debugging.
