What I'm looking for

I seek senior engineering roles building cloud-native, scalable systems with strong DevSecOps, mentorship, and opportunities to integrate AI/ML into product features.

I am a Senior Software Engineer with over a decade of experience delivering enterprise-grade solutions across the .NET ecosystem, Python, Go, and Node.js. I focus on building scalable microservices, modernizing legacy systems, and integrating AI/LLM capabilities to improve user experience and automation.

My recent work includes leading a migration from a monolithic C# .NET Framework application into microservices on Azure Kubernetes Service and introducing LLM-powered search and chatbot features that reduced call-center escalations by about 30%.

I have designed and implemented APIs, responsive front ends (React, Angular), ETL pipelines, and high-throughput event-driven systems while optimizing SQL Server and PostgreSQL performance and integrating NoSQL stores like MongoDB and Redis.

I mentor engineering teams, champion DevSecOps practices (SonarQube, Snyk), and deliver infrastructure-as-code using Terraform and Bicep to accelerate consistent provisioning and reliable deployments.
