What I'm looking for

I seek a collaborative engineering role leading backend or full-stack teams, building secure, scalable enterprise software with opportunities for technical ownership and cross-functional impact.

I am a results-driven Team Lead and Senior Software Engineer with a Bachelor's degree in Computer Science and strong expertise in .NET Core, ASP.NET MVC, Flutter, and SQL Server. I have led teams and delivered enterprise-grade modules for inventory, shipping, and API-driven services across sectors including heavy equipment and healthcare.

At Komatsu I collaborated directly with US teams to build inventory, pricing, back-order and reporting modules for a custom ERP, and I developed secure APIs and dynamic task management tools. Previously, I developed secure device APIs and billing integrations for healthcare applications, implementing HMAC SHA512 authentication, Entity Framework migrations, and optimized SQL schemas.

I co-founded a healthcare-software consultancy, drove product strategy, and built an ASP.NET MVC-based EHR and marketing platform for medical practices. I prioritize collaboration, security, and scalable architecture while continuously learning modern technologies to deliver impactful software.
