I am a .NET software engineer with 5+ years of experience delivering enterprise web apps, APIs, and cloud-native solutions. I specialize in C#, ASP.NET Core, EF, Angular, and SQL Server, with a strong focus on Azure DevOps, microservices, and CI/CD. I have hands-on experience across banking and insurance domains, optimizing performance, security, and deployment efficiency. I enjoy collaborating with cross-functional teams to ship secure, scalable software that meets business goals. In previous roles I led API design and data integration across multiple enterprise systems, modernized legacy frontends into reusable components, and implemented robust testing and monitoring to reduce defects and MTTR. I’m passionate about clean architecture, SOLID principles, and continuous improvement in Agile environments.
