A case study in modern AI-assisted development: Where decades of experience meets cutting-edge AI collaboration
CSV Generator Pro wasn't built by AI alone, nor was it built by traditional coding alone. It's the result of something more powerful: decades of hard-won experience in data engineering combined with the collaborative capabilities of Claude.ai.
The Problem: Working with AWS Athena and Redshift daily, I constantly needed realistic test data. Existing tools were either too simple, required signup, or didn't understand data engineering needs.
The Approach: I brought the requirements, Claude brought the implementation speed. Within hours, we had the core CSV generation engine working.
Experience Matters: Knew exactly what field types data engineers need because I've been one for decades.
The Challenge: Direct S3 upload with AWS Signature V4 authentication—not trivial.
The Collaboration: I knew what needed to happen (having configured countless S3 buckets). Claude helped implement the signing algorithm correctly. Together we debugged CORS issues, tested edge cases, added dynamic path templating.
The Result: A feature most commercial tools charge for, working flawlessly in the browser.
The Insight: From years of building ETL pipelines, I knew test data needed relational integrity—the ability to JOIN across datasets.
The Implementation: Claude helped architect the deterministic ID system. I refined it based on real-world use cases from my consulting work.
Innovation: This feature didn't exist in other free tools because it requires understanding how data engineers actually work.
The Details: Configuration presets, auto-save, multi-column sorting, pagination—features that separate hobby projects from professional tools.
The Experience: I've shipped enough production code to know what "production-ready" means. Claude helped implement it fast; experience ensured we didn't skip critical features.
This project embodies what I call "experienced vibe coding"—a new paradigm where seasoned developers use AI to move at unprecedented speed without sacrificing quality.
I've spent 20+ years in healthcare IT, data engineering, and consulting. I knew exactly what tool to build and what features mattered.
Claude.ai turned days of coding into hours. No boilerplate drudgery, no syntax lookup—just rapid iteration on ideas.
Decades of debugging production systems means I know what to test, what can break, and what users will actually need.
Some features emerged from the conversation—Claude suggested improvements, I validated them against real-world needs.
Built with simplicity and reliability in mind:
Why these choices? Because after 20+ years, I know that simple architectures are the ones that actually ship, scale, and stay maintainable. No build process, no framework churn, no deployment complexity. Just solid, working code.

CSV Generator Pro emerged from real needs encountered in daily consulting work. It's the tool I wished existed every time I needed to test a data pipeline, demo an Athena query, or validate a Glue crawler.
If CSV Generator Pro demonstrates the kind of execution, domain knowledge, and technical capability you need for your project, let's talk.
20+ years of experience + AI-accelerated delivery = Projects that ship fast without cutting corners
Based in Maryland, serving clients nationally in healthcare and data engineering.
CSV Generator Pro is a proof of concept for a new way of building software. Not AI replacing developers, but AI augmenting experienced developers to create better tools, faster, with higher quality than either could achieve alone.
The current version adds batch processing with per-config split settings. Complex features like this - with proper validation, error handling, and per-configuration persistence - would have taken weeks before. Now? A few hours. And it's production-grade because experience still guides the process.
This is the new normal: Seasoned professionals using AI to work at speeds previously impossible while maintaining the quality only experience can provide. The developers who thrive will be those who combine deep expertise with AI collaboration fluency.
