I've helped run an open source project based upon Ruby on Rails for eight years at https://github.com/EBWiki/EBWiki. In addition, I built an agent to fetch data from mysportsfeeds.com to power flumly.io, a site dedicated to alumni sports fans. This included feeding the site itself as well as feeding data to prompts into both SportsBERT and ChatGPT to evaluate LLM generated sports content.

Mark is an excellent tutor with deep knowledge of Ruby on Rails. In addition to teaching me about specific ways to address individual coding challenges as they have arisen, throughout multiple sessions, Mark has shown me more importantly, a lot about coding the right way to produce work that is tested, and robust enough enable easy collaboration. For anyone looking to up their understanding of programming concepts, project management and code organization, I would highly recommend seeking Mark out.

- Designed deep analytical test prompts requiring agents to explore, reason about, and verify real-world codebases without modifying them, simulating developer workflows.
- Used Cursor to automatically generate unit, integration, or end-to-end (E2E) tests after selectively removing specific tests from codebases, evaluating how well Cursor recreated the missing test coverage.
- Created rubrics and objective verifiers for comprehensive test coverage focused on uncovering blind spots and failure points after artificial test removals.
- Implemented a test suite and scoring framework that improved error detection rates and increased trust in model reasoning during challenges.
