Building scalable enterprise applications, APIs, and microservices for modern businesses.
Turning complex
problems into clean systems
I'm a Senior Software Engineer with 8+ years of experience designing and shipping production-grade backend systems for enterprise clients. My expertise spans the .NET ecosystem, cloud-native development on Azure, and microservices architecture — with deep experience in the insurance domain.
Over the years I've architected and delivered 10+ production microservices, designed RESTful APIs serving hundreds of thousands of users, and worked closely with stakeholders to translate complex business requirements into clean, maintainable systems.
Beyond code, I'm invested in growing the next generation of engineers — having mentored 10+ freshers into their first professional roles, guiding them through software design principles, clean code practices, and career development.
What I bring to the table
- Production-grade microservices architecture
- Azure-native cloud solutions
- Clean, maintainable, SOLID code
- Cross-functional team collaboration
- Developer mentorship & leadership
