Services, the flagship engagement
From messy workflow to working system: diagnosis, architecture, design, and a real build, in one focused engagement, not a six-month software project.

The OpsBuild Sprint is how I turn a messy workflow, a stuck MVP idea, or a “we need to finally see our numbers” into working software. One engagement, one leak, one system that closes it.
It starts where most projects skip: diagnosis. Before anything is built, we map where your business actually loses time, leads, or clarity. Then I design the smallest system that closes the leak, and build it. Not a prototype, not a deck of recommendations: software you log into.
You work directly with me. The person who maps your workflow is the person who architects the system is the person who builds it. Nothing gets lost between a salesperson, a PM, and a developer, because they're all the same person.
Five phases, in order. The order is the method.
We find the leak and map the real workflow, who does what, when, with which tool, including the embarrassing parts.
You get
A workflow map and a named, prioritized leak
The smallest system that closes the leak: architecture, data model, screens. You see and approve the shape before anything is built.
You get
System architecture and design direction
Working software early. You click a real build within the sprint, not at the end of it, and your reactions steer the rest.
You get
The first working version, in your hands
The system meets your real tools and real data. Then the experience gets polished, because software that isn't pleasant doesn't get used.
You get
An integrated, polished system
Ship it, document it, and map what comes next, what to build after, and just as importantly, what not to.
You get
A launch-ready system and a clear roadmap
I come from bookkeeping and business operations, not from a coding bootcamp with a logo generator. I've run the messy workflows I now build systems for.
FollowUpOS and DealSharp aren't portfolio fillers, they're live products I designed, built, and run. I make the same bets on my own work that I'll make on yours.
I use AI where it removes repeated work and keep humans where judgment matters. No magic-wand promises, no “agents will run your company” hype.
The metric isn't 'delivered'. It's 'still in use three months later'. That's why diagnosis and polish are non-negotiable phases, not add-ons.
English, Spanish, and Polish, your team, your clients, and your documentation don't need a translator between them and the person building.

These pages connect services, workflow pain, and practical examples. They help shape the first conversation before scoping a build.
Scoped per project, quoted after the diagnosis, because pricing a system before mapping the workflow is how estimates turn into fiction. You'll have a clear number before any building starts, and ranges to orient you after the first conversation.
Long enough to ship a working system, short enough to stay urgent, typically weeks, not months. The exact shape depends on scope, which is exactly what the diagnosis pins down.
Modern, boring-on-purpose technology: TypeScript, Next.js, proven databases, and AI where it earns its keep. You own the code and the accounts. No lock-in to a tool only I can operate.
You're not abandoned at launch. The handoff includes documentation and a roadmap, and if you want continued building or iteration, that's a conversation we have with the system already live, not a dependency built into the deal.
