Enterprise Platform Modernization

Modernized a legacy operations platform by moving WCF services and an Angular interface toward ASP.NET Core Web APIs, React and independently deployable services.

  • Split migration work into testable services while preserving existing business flows
  • Used TDD and BDD specifications to protect behavior throughout the modernization
  • Added Azure Service Bus, scheduled background processing and distributed caching for operational workloads

High-Performance Service Caching

Designed a hybrid caching path for a telecom self-service platform, combining application logic with Redis to remove repeated expensive work from a critical request.

  • Introduced cache-aware request handling while preserving the database as the source of truth
  • Used background jobs to refresh operational data without blocking user requests
  • Deployed and monitored the service in a containerized AWS environment

About

The short version

I am a tech lead and backend-focused software engineer with more than five years of experience delivering large-scale transformation projects across telecom and enterprise systems. My core stack is C#, .NET, ASP.NET Core, Entity Framework and SQL Server, supported by React and Angular where products need a web interface.

My work includes modernizing WCF and SOAP systems into RESTful microservices, building API ecosystems, improving performance with Redis, and delivering cloud-native workloads on AWS and Azure. I also have experience with event-driven systems, conversational-AI integrations, TDD, BDD and production support.

.NET Backend

Production APIs and background services built with C#, ASP.NET Core, EF Core and SQL Server.

Distributed Systems

Microservices, caching, queues and data pipelines designed for predictable performance and recovery.

Cloud Delivery

Containerized services delivered through Docker, Kubernetes, AWS, Azure and automated CI/CD pipelines.

More

Additional engineering work

Focused backend systems and delivery improvements from production environments.

Bulk Data Processing Pipeline

2025
