DevDudeJeremy is Jeremy Warren's independent product engineering practice. I build accessible web applications, grounded AI systems, and durable delivery workflows for organizations that need the work to keep making sense after launch.

- Product systems — accessible interfaces, maintainable back ends, integrations, payments, and data models designed as one coherent product.
- Grounded AI — retrieval pipelines and assistants anchored in the documents, policies, and knowledge that matter to the organization using them.
- Stewardship and modernization — focused improvements to performance, reliability, security posture, dependencies, and long-lived application code.
Across all three, accessible delivery, secure defaults, clear evidence, and a durable handoff are part of the work—not optional polish.
- Start with the real constraint. Technology choices should serve the people, operations, and risks already present.
- Verify the behavior that matters. Tests and review should follow the paths users and operators actually depend on.
- Leave ownership behind. Documentation, automation, and understandable code are part of the finished product.
Current toolkit
- Applications: Python, Django, JavaScript, TypeScript, React, Next.js, PostgreSQL, REST APIs
- AI systems: hybrid retrieval, knowledge pipelines, AI assistants, and governed AI-assisted development workflows
- Delivery: GitHub Actions, Cloudflare, Vercel, testing, observability, performance, and ongoing maintenance
Tell me what needs to work, who it needs to work for, and what cannot fail. I will help turn that into a practical next step.
