Technology consulting

You work directly with Terry. Here is what he brings.

Trained as a computer scientist: A Ph.D. in computer science from the University of Texas at Arlington and an M.S. from the University of Arkansas, followed by a career as a professor of computer science, where the daily work was making hard ideas plain. His teaching earned university-wide awards.
Experienced at working with people: He has chaired a university department, led committees, managed budgets, advised students and mentored teams through real software projects. He is used to working with people who are not technical and with the outside parties a project has to satisfy.
Skilled with AI tools: He builds with current AI models and coding assistants every day: writing software, automating routine work and producing content. He can help you see where AI will save you time, where it won't, and how to put it to work safely.
A builder of web applications: Since 2010 he has written, hosted and maintained a production web application that behavioral health organizations rely on, with the privacy and uptime that healthcare demands. He also designs and ships the apps shown below.
Available for consults: A single conversation, a second opinion or a short project. Typical topics: planning or reviewing a web application, choosing and adopting AI tools, automating a manual process, hosting and security basics, and technical training. Send a note describing what you need.

Cooklist

Plan. Shop. Cook.

Cooklist is a web app for home cooks. It plans meals around your household's tastes and eating styles, turns them into one shopping list, and walks you through the cooking at the stove. It is built for the phone first and shared by everyone in a household.

Meal plans and recipes written by AI to fit your household's preferences and kitchen
A shopping list organized by aisle, scaled to the number of people eating
Cook mode: one step at a time, with timers, in sync between phone and laptop
A recipe library that remembers what you rated and liked

Cooklist is in invite-only beta and is operated by Sergeant Services. The app is free to use. Its AI features run on AI credits: each account starts with a free allowance, and one-time credit packs, with no subscription, are being introduced. Purchases and refunds are covered by the Cooklist terms; see also its privacy policy.
