What I'm looking for

I am looking for a role that challenges me technically and offers opportunities for leadership and mentorship in a collaborative environment.

I am a Senior C# Full Stack Engineer with over 13 years of experience in designing, architecting, and deploying high-performance applications across various industries including Fintech, E-commerce, Healthcare, and SaaS. My deep expertise in C#, .NET 6/7, and ASP.NET Core allows me to build scalable microservices and robust APIs that meet complex business needs. I am passionate about delivering cloud-native solutions using Microsoft Azure and AWS, ensuring that applications are not only functional but also optimized for performance and user experience.

Throughout my career, I have demonstrated a strong DevOps mindset, implementing CI/CD pipelines and leveraging containerization technologies like Docker and Kubernetes to streamline deployments. I have a proven track record of mentoring junior developers and fostering a collaborative team environment that emphasizes Agile practices. My commitment to code quality, performance optimization, and security best practices has consistently driven engineering excellence in my projects.
