Software Engineer
Backend Developer & Azure Specialist
I build reliable backend systems and cloud solutions that power enterprise growth. With over 9 years of experience in Software Development, I help companies transform complex technical challenges into clean, scalable, and high-performing software.
About Me
As a Systems and Computing Engineer with over 14 years in tech, I've built my career around one principle: reliability matters.
From technical support to leading software teams, I've learned how to design systems that scale — and how to help people grow with them.
My core focus is backend development using .NET and Azure services, building secure, high-performance APIs and enterprise applications. While I specialize in backend, I also enjoy collaborating across frontend and DevOps to deliver complete solutions.
