About George

Senior .NET & C++ Software Engineer | Backend & Cloud Systems

I am a high-performance Senior Software Engineer with over 15 years of hands-on experience designing, developing, and optimizing distributed backends, desktop systems, and cloud-native solutions. I specialize in stripping away technical debt, writing highly optimized C# and C/C++ code, and building resilient API layers capable of handling enterprise-scale workloads.

My expertise bridges modern cloud ecosystems with low-level memory and database performance tuning:

🛠️ Core Technical Stack:
  • Advanced .NET Ecosystem: C#, .NET 8/9, ASP.NET Core Web APIs, EF Core, LINQ optimization, and Azure Functions

  • Low-Level & Desktop Engineering: C/C++, Win32 API, MFC, WPF, and cross-platform native porting (Desktop to iOS/Android).
  • Enterprise Data Layers: Advanced T-SQL, MS SQL Server, query performance optimization, and relational database architecture.
  • DevOps & Resiliency: Automated CI/CD (Azure DevOps, TeamCity).

⚡ Technical Impact & Execution:
I specialize in solving deep technical bottlenecks and handling high-risk codebase modernizations. I recently engineered the end-to-end migration of a massive, multi-tiered enterprise risk analytics platform—successfully porting 140+ project solutions from legacy .NET Framework to modern cross-platform .NET. I excel at minimizing memory footprints, eliminating database connection latency, and maximizing API throughput.
