What I'm looking for

I want to build secure, high-performance .NET microservices in the cloud and integrate real AI/ML capabilities end-to-end. I’m looking for teams that value reliability, DevOps discipline, and cross-functional collaboration with measurable business impact.

I’m a performance-driven Senior .NET & AI integration engineer with 6+ years focused on the .NET ecosystem, high-performance cloud architecture, and practical AI/ML engineering. I design and deploy scalable enterprise applications—microservices and secure API-driven platforms—then enhance them with predictive analytics, automated recommendation engines, and RLHF-style post-training reinforcement learning loops.

Across client and enterprise work, I build fault-tolerant microservices integrated with AWS and Azure, implement secure authentication/authorization (OAuth2, JWT, RBAC), and deliver developer-friendly API docs with OpenAPI/Swagger. I’ve also optimized SQL Server and PostgreSQL with indexing and query tuning, including an approximate 40% reduction in API response times, while building feedback and evaluation pipelines that continuously improve model outputs.

I lead cross-functional collaboration, mentor teams, and treat reliability as a feature—establishing robust DevOps pipelines, end-to-end CI/CD, automated testing, and monitoring to keep systems stable at scale. As an Independent Full Stack & AI Consultant, I’m especially excited by end-to-end delivery that bridges technical innovation with measurable business outcomes.
