What I'm looking for

I'm seeking a mid-level software role focused on backend performance, scalable architectures, and database optimization within collaborative Agile teams that offer mentorship and clear technical growth paths.

I am a software engineer focused on building efficient, maintainable backend systems. I optimized hierarchical resource reservation to reduce schedule loading time by 51% and simplified API endpoints to reduce redundancy and improve maintainability.

I work across C++, Java, C#, Python and SQL, maintaining legacy systems and implementing new features that cut manual interventions and downtimes. I migrated a .NET Framework project to .NET Core 5, implemented error monitoring, and optimized database access to improve scalability and observability.

I enjoy mentoring and teaching procedural programming while contributing to full‑stack projects using Angular and WebSocket for real‑time features, with an emphasis on testing and documentation. I seek collaborative Agile teams where I can continue improving system performance and help onboard and grow other developers.
