This is work I did for an employer. These belong to someone else, so there's no code to view. What I can tell you is what I owned and what shipped.
Architect and full-stack developer
A multi-tenant phishing simulation platform on ASP.NET Core and Angular. I architected it, and it went well past the gophish port it started from, adding recurring campaigns, live editing, template pools, and LMS integration, with the credential capture deliberately removed.
Sole developer, end to end
Turns documents, video, and a quiz into a SCORM package. Built for our customers' LMS administrators, who may not know what SCORM is and shouldn't have to.
Localization engine design and refactor
Replaced thirty-odd translation functions and twenty naming conventions with one localization engine, plus the standards and documentation that keep it that way.
Subject matter expert and content writer
Branching security scenarios where the learner picks a response and sees the consequence, including the plausible wrong answers that fail for reasons you wouldn't guess.
Our regression testing used to run on Selenium. I moved it to Playwright, which is the first step toward running it in the pipeline. A Postman suite of more than a thousand requests needed reorganizing and trimming, so I did that as well. The converter that pulls existing client courses out of the old authoring tool is mine, and without it the migration doesn't happen. I also write and maintain the UI unit tests. A good deal of the UI work on our current platform is mine, along with plenty of the UX calls.
Further out from code, I evaluated the options for our public knowledge base. The team went with my recommendation, so I built it out and wrote the articles. I've designed and overseen a large feature overhaul, and I built automated license tracking with reporting for leadership. The internal review process and its triage were mine to run.
The role has also covered SCORM and screen-reader QA, managed services, website maintenance, product support, and product ownership for several vendor platforms. All useful background. None of it is where I'm headed.
