What I'm looking for

I’m looking for a role where I can build and scale backend systems and microservices, own performance improvements in production, and collaborate with global Agile teams—while mentoring others and continuously learning with modern tooling.

I’m a Senior Software Engineer with 10+ years designing and scaling distributed systems in fintech and banking. I build high-performance, production-grade services using .NET Core, C#, and microservices architecture.

I’ve solved critical performance bottlenecks—reducing API response time from ~3 minutes to ~20 seconds (~90% improvement). I also leverage AWS and Azure for cloud-native development focused on scalability, reliability, monitoring, and system health.

I collaborate in global Agile teams, mentor engineers, and drive engineering best practices. I enjoy using AI-assisted development tools like GitHub Copilot to improve productivity, solution quality, and delivery in remote environments.
