What I'm looking for

I’m looking for a role where I can build cloud-native backend/full-stack systems—especially AI-driven microservices—lead cross-functional execution, improve performance, and automate CI/CD so products deliver reliably and meet business goals.

I’m a Senior Full-Stack Developer with over 10 years of experience designing and delivering robust, scalable AI/ML-powered applications. I specialize in backend development with a strong command of ASP.NET Core and C#, and I thrive at turning complex requirements into clean, maintainable systems.

I’ve led migrations from legacy platforms to modern, cloud-native microservices—most notably architecting and building Azure-based services that improved scalability and system performance. I develop AI-driven backend Web APIs and integrate GenAI capabilities (including OpenAI APIs) to power user-facing experiences, such as chatbots with fast, personalized responses using vector database indexing.

I’m also focused on measurable performance gains and delivery reliability. I optimize SQL Server stored procedures to reduce report generation time dramatically, integrate caching (like Redis) to improve response times, and streamline deployments by designing automated CI/CD pipelines and containerized infrastructure workflows across many services.

Across full-stack and platform work, I build responsive user interfaces with Angular (and related front-end technologies) and develop secure, service-oriented integrations using OAuth, Web APIs, messaging, and modern cloud tooling. I enjoy partnering with stakeholders, guiding Agile execution, and mentoring teammates so products ship on time and continue to improve after release.
