Derek Stringer — A Founder's Coder

What I do

Two problems. One guy who fixes both.

Agencies quote $50K and four months. Freelancers take the deposit and vanish. "No-code" falls apart the second you need something real. And nobody sticks around after launch. I know — I went looking for years. So here's the deal:

Lane 1

You've got an idea stuck in your head.

That app or tool you've been describing to people for years. I take it from "wouldn't it be cool if…" to a real, working product people can actually use — in weeks.

Lane 2

You're tired of renting your software.

Calendly, your CRM, team chat, invoicing — all those monthly bills you resent. I build your own version, and you own it. No more per-seat rent.

What I can build

Websites. CRMs. The system your business runs on.

If your business needs it, I can build it — and you'll own it. The ones founders ask me for most:

Websites & landing pages CRMs & lead pipelines Booking & scheduling Custom management systems Internal tools & dashboards iOS & Android apps AI assistants & automation Invoicing & payments

That "custom management system" is the big one. Mine's an FMS — a Fleet Management System. Yours might run on inventory, property, patients, jobs — whatever it is, I build the [your]MS to fit how you actually work, instead of forcing your business into some off-the-shelf box.

And I wire it into what you already use. I replace the software you're overpaying for — and integrate the tools you have to keep: Zoom, Stripe, QuickBooks, your scheduling, your industry's must-have systems, even software someone custom-built for you.

The proof

Apps I've shipped

Not concepts. Not "in progress." Live software I designed, built, and deployed myself.

RoboTaxi Club

Founder & sole builder

A full fleet-management platform built from zero: mobile app + web admin + database + a custom AI assistant with 25 tools. Lead pipeline, e-signature contracts, automated SMS & email, a booking engine, financial modeling, push notifications — and a fully automated deploy pipeline behind it. This is what companies hire whole teams to build. I built it solo.

RideTracker

Built to solve my own problem

A company kept underpaying me, so I built an app to catch it. It logs every ride by GPS, auto-calculates the mileage and the pay I'm owed, and audits it against what actually hit my account. Background GPS, screenshot OCR import, route planning — the works.

Derek Money

Designed & built solo

A personal-finance app built around how money actually moves — not how accountants think. Bill tracking, subscription management, debt payoff, a live P&L, and a 796-rule engine that auto-categorizes every transaction. No spreadsheets. No QuickBooks.

A finance tool I use every single day

The wedge

Own your SaaS stack.

Every month you rent your tools by the seat, the bill goes up and you own nothing. I build your own versions of the software you're paying for — and they're yours. I've already done every one of these for my own company:

Calendly→Your own scheduler

QuickBooks→Accounting, built in

Slack / Teams→Your own team chat

CRM subscriptions→A CRM you control

Pay me instead of your SaaS.
Then fire me and keep your stack.
Your software stack. Your stack of cash. Keep both.

Honest version: owning it kills the per-seat monthly rent — you just cover basic hosting (a fraction of what you pay now). You stop renting, and you stop being held hostage by someone else's price hikes.

Why me

I've been you. That's the whole point.

→I've been you.

A founder who needed software and got burned looking for it. I build for that person because I was that person.

→I ship — and I'm fast.

Three live apps, not a folder of concepts. I build with the AI tooling moving the whole industry, so you get founder speed.

→Scope creep? Bring it.

Most builders punish you for wanting more with change orders. I expect it — wanting more means it's working.

→I don't disappear.

Month-to-month, no lock-in, my cell — not a ticket queue. The opposite of every dev who ghosted you. And you always own the code.

How to work with me

Simple, flat, no surprises

No hourly meter. No change-order games. Pick the lane that fits — not sure, start small and we'll figure it out together.
