I’m Tom Hall — a senior engineer who has spent ten years shipping software for an airline, a telehealth platform, and my own SaaS (acquired in 2021). I build the custom apps and integrations your business needs next: too complex to DIY with AI, nowhere near a $100k agency quote. You own everything I build.
// sound familiar?
// what I build
Built around how your business actually works — not bent to fit generic software. I scope, design, build, and hand off myself: senior-level work without the agency layer, here in DFW.
Custom MVPs & new products
A real, shippable first version of the product or tool you’ve been sketching — scoped tight, live in weeks, built to grow instead of being thrown away.
↳ Founded and sold Electask — SaaS used by 3 California county election offices.
Integrations & glue code
The custom layer that connects your CRM, billing, ops tools, and spreadsheets — so data stops getting re-typed and your reports stop disagreeing.
↳ Built service integrations across airline ops systems at Breeze Airways.
Dashboards, portals & back-office apps
The spreadsheet that runs the company, turned into real software — logins, permissions, an audit trail, and one source of truth.
↳ Shipped Breeze’s ops board and airport kiosks; Refill’s platform serves 200+ practices.
AI features & automation
LLM-powered intake, drafting, and workflow automation built into the systems you already run — applied where it makes money, not where it demos well.
↳ Head of Engineering at Refill, shipping AI-assisted telehealth tooling today.

The problem
Practices want to prescribe GLP-1 medications, peptides, and controlled substances online, but the existing telehealth platforms are too rigid and expensive for both big and small practices.
What I built
A custom telehealth prescribing platform with all the tools a practice needs to manage patients, prescriptions, and refills — plus a patient portal for intake, marketing, and secure messaging. Built on React, Node, Postgres, and AWS.
Result
Fully live with 200+ practices, well over 40,000 patients, and tens of thousands of prescriptions.

Before anyone writes code, I map what you have and what it’s costing you. In one to two weeks you get:
Systems Audit
It starts with a free intro call to make sure the audit is even worth your money.
// ways to work together
Systems Audit
A map of your stack, where it leaks money, and a prioritized roadmap with real estimates. Yours to keep — use it with me or anyone.
Focused build
One well-scoped app or integration: an MVP, a customer portal, the glue between two systems. Fixed fee, agreed up front.
Bigger build
Multi-phase work: a product with several moving parts, or replacing a duct-taped stack one piece at a time.
Retainer & fractional CTO
Ongoing development from $5k/mo, or fractional CTO from $3k/mo — architecture, vendor calls, hiring help, and a senior engineer who already knows your stack.
// how it works
The code, the infrastructure, the data — yours from day one. No lock-in, no held-hostage logins.
No agency, no account manager, no junior devs learning on your dime. The person on the call is the person writing the code — and I’m in DFW, happy to meet in person.
Every phase is scoped and priced before it starts. No hourly meter, no surprise invoices.
A decade of shipping means I’ll tell you what not to build — and when off-the-shelf is genuinely good enough.
// questions owners ask
A free 15-minute call, one-on-one. You tell me what you’re trying to build and what you’re running today; I tell you honestly whether it’s a fit and what I’d do first. If the right answer is “don’t hire me,” you’ll hear that too.
A map of your current stack and how data actually moves through it, where it’s costing you time and money, and a prioritized build roadmap with honest estimates — including anything you should buy off the shelf instead of building. Fixed fee from $1,500, done in one to two weeks, and the document is yours to use with anyone.
A focused build — one well-scoped app or integration — runs $10k–$30k over 4–6 weeks. Bigger multi-phase work runs $30k–$60k over 8–12 weeks. Every project is a fixed fee agreed up front — no hourly billing, no surprises.
Senior technical leadership a few hours a week without the full-time hire: architecture decisions, reviewing vendor and agency quotes, hiring help, and a roadmap someone is actually accountable for. Fractional CTO starts around $3k/month; ongoing development retainers run $5k–$10k/month depending on scope.
Maybe — and if I think you can, I’ll say so on the call. AI tools are genuinely good at prototypes. Where they stall is production: auth, payments, data modeling, integrations with your existing systems, and the edge cases that show up with real customers. That gap is exactly the work I do.
Yes — that’s usually the point. Most engagements integrate with the CRM, billing, and ops tools you already run rather than ripping them out. Almost anything with an API can be connected; I’ll confirm specifics on the first call.
Yes — full ownership transfers to you, and the IP terms are spelled out in the engagement letter before any work starts. That includes the audit roadmap: it’s yours even if you never hire me to build it.
You’re not stranded. Hand-off comes with documentation and a walkthrough, and most clients keep a monthly retainer for fixes, improvements, and new features. Either way you own the system and can take it anywhere.
No — everything works over video. But I’m based in Burleson, and for DFW businesses the audit and working sessions can happen at your office, in person.
// let’s talk
Book an intro call — 15 minutes, no pitch. Tell me what you’re trying to build; I’ll tell you honestly whether it’s a fit and what I’d do first. Local to DFW, so the first meeting can be in person.
