What I'm looking for

I am seeking a role that fosters innovation and collaboration, where I can leverage my skills in full-stack development and contribute to impactful projects in a dynamic environment.

As a Senior Software Engineer with over 12 years of experience, I specialize in building secure and scalable full-stack applications using .NET Core, ASP.NET Core, and ASP.NET MVC, alongside modern frontend frameworks like React, Next.js, and Angular. I have proven expertise in designing and delivering RESTful APIs, microservices, and cloud-native solutions across healthcare and education domains. Skilled in optimizing Oracle and SQL Server databases for large-scale systems, I am also experienced with containerization using Docker, orchestration with Kubernetes, and implementing CI/CD pipelines for fast, reliable deployments. I am passionate about writing clean code, ensuring accessibility standards, and bridging backend and frontend technologies to deliver seamless user experiences.

Throughout my career, I have successfully designed and developed HIPAA-compliant healthcare platforms, optimized database performance, and automated CI/CD pipelines to enhance deployment efficiency. My commitment to clean code and improving developer workflows has consistently resulted in technology solutions that serve users effectively. I thrive in collaborative environments, partnering with stakeholders to align technology with clinical needs and ensuring compliance with regulatory standards.
