Dallas Crilley

Business systems & integration engineer.

CRM, billing, vendor APIs, and the internal tools that make them agree.

Systems
  1. Meter Shipped. Telecom usage into ConnectWise invoices. Preview before write.
  2. Throughline Shipped. Six vendor APIs, one connector contract, one client record.
  3. CoHost In progress. An AI media pipeline a person has to release.
All work Python · TypeScript · Postgres

I fix the part of a business where the CRM, the billing system, and a few vendor APIs don't agree.

Ten years doing it inside my family's PR firm in Dallas, where I was the only engineer. I sit with the person who runs the process, find where it breaks, and build something they can run without me. Python and TypeScript. These days there is a fair amount of AI in the pipeline, with a human holding the release button.

Three things I fixed

Monthly billing that took a person and produced disputes

An MSP was re-keying Intermedia phone usage into ConnectWise invoices every cycle, account by account. Charges landed on the wrong agreement. A retry after a timeout could bill someone twice. I built Meter to do the transfer. It pulls the usage, maps it to the right agreement, shows the operator a preview of what will change, and only then writes. Per-account locks stop two syncs from colliding. When ConnectWise answers a write with an ambiguous error, Meter queries back and matches a content hash before deciding whether to retry.

It runs in production today. One reconciliation audit in December 2025 covered 202 accounts and 931 work items and turned up a tax-row identity bug before the next invoice went out. That number is from my own incident notes, so take it as a description of one audit, not a monthly volume.

Six vendor systems and no single view of a client

The firm ran on QuickBooks, Copper, Basecamp, PandaDoc, Acuity, and Airtable. Finance and ops answered "what do we have with this client" by opening all six. I built Throughline. Every vendor sits behind the same four-method connector, and one engine owns incremental sync, retries, health checks, and the write into Postgres. A new connector gets all of that for free. Each run fetches only what changed since its last checkpoint, which the architecture notes put at roughly a third of the API calls a full refresh would make.

The result is one customer record with the invoices, deals, projects, contracts, appointments, and notes attached. Staff read it from a dashboard instead of reconciling six tabs. The connector contract is public as throughline-connector-kit.

A media pipeline that could publish garbage

The podcast side of the business needed transcripts, edit points, and social copy for every episode, and the first version was a script that called a model and hoped. CoHost AI Studio replaced it with a pipeline where every stage writes out what it produced, so you can open the transcript and see exactly where the edit detector decided to cut. Before anything publishes, a quality gate scores the output with a mix of programmatic checks and a second model, and a person decides whether it goes.

I don't have a clean before-and-after number for this one and won't invent one. What I can say is that the gate has blocked releases, which is the point of having it.

How I work

I learned this inside my father's company. There was no one else to hand a ticket to, so I owned the requirements conversation, the build, the deploy, the 2am page, and the explanation afterward. The title on my résumé, Technology & Business Systems Lead, is a description I wrote; the company never assigned one. Judge the systems.

I start by watching someone do the job. Most of what I build is a straight transcription of what they were already doing by hand, with the failure modes turned into code. I'd rather ship a preview step than a confidence score. When a model is in the loop, I want its work inspectable and a human able to stop it.

I'm looking for business systems, integration, or technical implementation work, full-time or contract, at a company that runs on a CRM, a billing system, and a handful of vendor APIs and needs them to agree. Dallas-Fort Worth, remote, or a few days a week on site.
