Selected work

Some examples of the systems I've designed, built, and shipped.

Negentropic Solutions is a one-person practice — I'm Ben Deniston, and every system below I built firsthand, most in senior in-house roles building and running the data and integration systems for the organizations I worked with. It's the hands-on experience the practice is built on.

A single source of truth lets you use AI in your voice

9 systemsunified into one store
In your voicegrounded in your own facts

This organization's content and supporter data lived in nine separate systems that didn't talk to each other — so nothing saw the whole picture, and off-the-shelf AI produced generic, off-brand output. I unified all nine into one organized, structured source, then built an AI content pipeline on top of it: it drafts in the organization's own voice, grounded in its own facts, and never publishes without a person's approval. The result is AI that sounds like them and works from their material — the opposite of generic.

AI Automation

AI customer support agent, running on your data

Every messagesorted & context pulled automatically
~1,500backlog conversations cleared

Customer email requests were arriving faster than the team could handle. I built an AI agent that works alongside the support team: for each conversation it decides how to pull the relevant customer information across four separate systems and provide a single view, ensuring the staff can respond quickly and accurately. They get draft email replies in the organization's voice, but the AI proposes and people decide — nothing goes out unreviewed. This turned a chaotic flow into a streamlined process.

NetSuite

Purchasing that always buys from the cheapest supplier

3 vendorsinto one unified catalog & ordering
Every orderrouted to the lowest-cost source

I built a complete product-catalog and ordering integration between a NetSuite ERP and three wholesale distributors. At order time the system compares each item's latest cost across all suppliers and automatically selects the lowest-cost source — providing significant annual savings.

NationBuilder

Track every new supporter — and let AI surface who needs follow-up

Engagementmonitored over time
AI surfaceswho needs follow-up

Growing organizations lose track of who signed up, where they came from, and who needs follow up. I built a custom integration for NationBuilder that records how every new supporter entered the database, and tracks their activity and engagement over time. On top of this, I built AI assessments that find the 'needle in the haystack' — the specific people who are ready for personal follow-up, so organizers spend their time on the supporters who matter most.

A custom reorder-point system, built on your own sales history

60,000+ productseach with its own ordering needs
Fewerstockouts and dead stock

Deciding when to reorder, and how much, is the critical middle ground between empty shelves and cash tied up in dead inventory. I built a custom reorder-point and demand engine from the business's own sales history — accounting for seasonal demand, supplier lead times, and the safety stock each product needs. This gave their purchasing team automated ordering guides for every one of 60,000+ products, across multiple locations.
