Finding what the data is hiding
Data specialist in Sugar Land, Texas. 7+ years of writing SQL, finding the story in the data, and explaining it to the people who need it.
About me
I’m a data specialist with 7+ years of writing SQL that answers real business questions, and turning what the data shows into clear decisions for leadership and front-line teams alike.
My recent roles built the pipelines and data models behind health plan reporting, so I understand how data is shaped from source to dashboard, and where it breaks. That is what makes the analysis on top of it trustworthy. My strongest tools are advanced T-SQL (window functions, CTEs, performance tuning), Power BI, and Python.
I work hands-on with Claude Code and OpenAI Codex, using context engineering and spec-driven development to get from a question to a trusted answer faster. At Apex Health Solutions I partnered with the VP of Technology to roll out Claude Code safely in a regulated environment, and I quantified the ROI of AI-powered process changes for leadership.
I have also built and run my own businesses across professional services and e-commerce, so ROI-driven decisions and the cost of getting it wrong are not abstractions to me. Today that includes Calamity Technology Solutions Group (CTSG), which helps Houston home service companies turn the customer data they already have into booked jobs, with every campaign measured against a holdout group.
Outside of work I create my YouTube channel, AnthonyJCTSG, sharing practical guidance on AI, agents, and data analytics. I also build browser games as a way to keep shipping finished, polished things end to end.
The standard I hold the work to is the one on my front page: do it right the first time, you won’t have to do it again.
