What I'm looking for

I’m looking for a senior role where I can modernize legacy systems, design microservices on Azure/AWS, and drive CI/CD and security. I want an Agile team where I can mentor others through code reviews and engineering best practices.

I’m a Senior .NET Engineer with 13+ years designing, developing, and maintaining enterprise applications using Microsoft technologies. I lead modernization efforts—refactoring legacy systems and applying design patterns to improve performance, reliability, and developer productivity.

In my recent role, I modernized a 20-year-old software suite, reducing downtime and support tickets, and designed microservice architectures using REST and Azure services. I’ve built high-performance solutions with .NET 6 and Azure Serverless, integrated real-time messaging with Azure Service Bus, and streamlined API management with GraphQL and Swagger UI.

I’m hands-on across the full SDLC with strong Agile/Scrum practices, mentoring, and code reviews to maintain quality standards. I also deliver secure, scalable deployments through CI/CD (Azure DevOps) and container orchestration (Kubernetes), while supporting data engineering and integrations using Kafka, BizTalk, EDITransactions, and SSIS.
