What I'm looking for

I aim to grow by designing .NET cloud microservices (AWS/Azure) for high-demand environments, optimizing latency, efficiency, scalability, and secure REST/SOAP integrations.

I am a software developer with over 3 years of experience, specializing in the .NET ecosystem and low-level systems development. My focus is on designing microservices and cloud architectures with a clear goal: improving performance and hardware efficiency.

At Efipay, I developed and implemented a microservices architecture using AWS Lambda and API Gateway, achieving a 30% reduction in latency and a 20% increase in transactional processing speed. My work has been centered on optimizing communication between services and ensuring secure integration with high-traffic banking systems.

I also strengthen solutions through low-level engineering: I implemented custom HTTP servers in C/C++ and network communication using TCP sockets, optimizing memory management and data transfer. At Pantherahub, I led the refactoring of RESTful/SOAP APIs, integrations with internal databases, and banking connectivity using the OASIS standard with WSSE and JWE, in addition to developing React and Vanilla JavaScript components for service interfaces.
