What I'm looking for

I’m looking for backend engineering work where I can design reliable, high-availability systems using OO principles—especially microservices and telecom/fintech integrations—paired with strong CI/CD and clean workflow practices to continuously improve outcomes.

I’m a Senior Software Engineer with software development and integration experience across broadcast, telecommunications, and fintech banking, focused on C/C++ and C#.

I’ve built high-availability microservices and improved reliability by 30%, while also reducing transaction time by 50% through optimized C++ implementations. I’ve implemented C++ RESTful services handling deployments and version management across 50+ versions seamlessly.

In fintech environments, I’ve delivered measurable performance gains—up to 40% in a .NET 6 API—by applying asynchronous programming, and I’ve designed and implemented new modules using CQRS (MediatR), Domain Driven Design, and CLEAN architecture principles.

I’m especially interested in software design and project workflow within the OO paradigm, backed by strong DevOps practices (Git, Jenkins, Docker, CI/CD) and a deep understanding of network/security fundamentals used in telecom systems like SIP gateways and signaling/media platforms.
