What I'm looking for

I’m looking to build secure, scalable microservices in .NET—leading modernization, strengthening PCI/OWASP security, and shipping reliable payment/auth solutions in cloud environments with strong engineering standards.

I’m a Senior Software Engineer with 8+ years of experience delivering secure, encrypted systems for financial services. In my current role, I develop critical authentication and anti-fraud capabilities, evolving authentication APIs with .NET 9/.NET 10, Mediator pattern, and Refit within a microservices architecture.

I’ve also led modernization initiatives—migrating legacy applications to modern web architectures with .NET and React, building secure API gateway flows (Apigee), and strengthening security through PCI-DSS/OWASP-aligned practices and vulnerability remediation. I focus on scalability, high availability, and dependable delivery across AWS/Azure/GCP, while collaborating with global teams and driving stability improvements (including a 98% reduction in processing time and a mobile app reaching 250k+ downloads).
