Independent Developer — Delaware
I'm Craig. I build tools that make data work.
I spent 23 years running underground utility and infrastructure crews as a Site Superintendent. I managed complex jobs, kept projects on schedule, and learned that the difference between a good outcome and a bad one usually comes down to whether the data is clean and the workflow is solid. I brought that same mindset into software.
The background
23 years in the field
I ran underground utility and infrastructure contracting crews for over two decades — water mains, gas lines, fiber conduit, heavy civil work. As a Site Superintendent I was responsible for scheduling, crew coordination, safety, and making sure jobs came in on time and on budget. That career taught me how to scope work clearly, communicate with clients, and deliver without excuses.
My body started limiting what I could do in the field. So I made a decision: build a second career before I needed one. I started learning Python, shipped my first tools, landed my first paid project, and kept building.
What I build now
I focus on the unglamorous but essential work that keeps data-driven businesses running — cleaning messy files, extracting structured records from websites, building automation scripts that handle repetitive workflows, and packaging those tools so clients can actually use them.
Everything I ship comes with clear documentation, clean output files, and a summary of what was done. No black boxes. If you can't understand what I built, I haven't finished the job.
What I'm building
CSV Cleaner
Self-serve tool for cleaning messy spreadsheets. Upload, clean, download. Live at csv.crkdev.com.
Spectral
Production data pipeline for CSV cleaning and web scraping jobs. Live at spectral.crkdev.com.
More coming
Building more tools and datasets through Spectral. Lead gen pipelines, enriched contact data, and more.
Working with me
Projects start at $150
Most small jobs — file cleanup, a focused scrape, a simple automation script — fall in the $150–$400 range. Larger pipelines, multi-source scraping, or ongoing work typically runs $400–$800+. I scope everything before work starts so there are no surprises.
How I work
You tell me what "done" looks like. I ask clarifying questions, confirm the scope in writing, and deliver. If something comes up mid-project I flag it before it affects the timeline or price. I don't disappear and I don't over-promise.
What I need from you
A clear target — a file, a URL, or a workflow description. The messier the problem the better, honestly. I built these tools specifically for the kind of data work that's too tedious to do manually and too specific for off-the-shelf software.
