Developed .NET back-end software supporting traveling clinicians. Advocated for better practices and better software quality. Collaborated with other teams, both developers and product owners. Worked with Azure from DevOps repositories to pipelines to service bus, service fabric clusters, and app configurations, with MS-SQL databases

Supported client's efforts to transition legacy systems to cloud-based architecture. As part of this effort, I coordinated and collaborate across various teams as I spun up a new Agile team I also developed a POC as a demonstration of where the architectural direction could go.

Developed C# .NET back-end applications to support e-commerce – applications ingesting from upstream systems, composing, and conveying to downstream systems, involving large data volumes.- Managed complex systems under heavy load, devising ways to track not only app behavior but behavior of data flows- Worked with upstream and downstream partner teams to implement new features and to investigate internal service desk problems- Optimized Marten event-sourcing system- Upgraded part of our RabbitMQ event-driven ecosystem- Mentored engineers in better practices, like encouraging greater depth in MR descriptions or training them in investigative approaches- Shifted toward metadata use from RabbitMQ to internal to Marten events- Continuously advocated for process improvements, including with our deployment stack (GitLab, Docker, Helm, Azure, AKS)- Encouraged gradual consistency in approach in fast-grown complex system with small iterative changes shifting towards a larger goal

My software development history is over at CodeOnward.com and my recent code is on GitHub under crjcodes.A career portfolio site and an avocational site for writing.

I planned, designed, developed, marketed, authored content, and maintained this website. Based on the b2evolution blogging platform, the site had not only has a customized theme but also several custom plugins I developed. Development included HTML, CSS, and PHP accessing a mySQL backend.

Developed and maintained products for managing bookstores
