Define and enforce rigorous peer/code review processes, providing actionable feedback

elevate team practices

Serve as the technical authority and primary escalation point for complex technical decisions across both legacy and modern platforms
Oversee the maintenance, optimization, and modernization of existing technology stack

while introducing modern frameworks and tools

Evaluate and integrate modern technologies including Marten, Wolverine FX, Postgres, Entity Framework, and LINQ
Identify opportunities to refactor legacy systems, improve technical debt, and enhance

system performance

Champion DevOps automation, integrating automated quality and security checks into CI/CD pipelines
Implement infrastructure as code using Terraform or Bicep for Azure resources
Design and implement containerization strategies using Docker and Kubernetes where appropriate
Partner with leadership to define the technical roadmap for the software platform transformation
Translate business requirements into technical solutions that work across both legacy and modern environments
Communicate complex technical concepts to non-technical audiences, ensuring alignment across departments
