The case board

Systems I've built, and what each one proves.

Four cases, no inflation. For each: the problem it came from, the system that answers it, and the business lesson it left behind.

Case 01, SaaS, follow-up system01 / 04

FollowUpOS

The problem

Good leads don't usually say no, they go quiet, because somebody got busy and the follow-up never happened. I watched it in my own pipeline and in every sales-driven business around me: the leak wasn't lead generation, it was lead memory.

The system

A daily follow-up system: every lead carries its history, its next touch, and a reminder that doesn't negotiate. AI drafts the message in your voice so the follow-up takes seconds instead of willpower. A Chrome extension meets people where the conversations actually happen. Pipeline visibility shows what's warm, what's cooling, and what's already cold.

What it proves

That I can take a fuzzy, universal business pain and ship a focused product around it, scoping, designing, building, and running the whole system end to end.

Case 02, Platform, real estate analysis02 / 04

DealSharp

The problem

Real estate investors make six-figure decisions with envelope math, and operators run portfolios with bookkeeping that lags months behind reality. The numbers exist, scattered across PDFs, sheets, and heads, but nothing turns them into decisions.

The system

A deal analysis platform: calculators for the numbers that decide a deal, stress tests for the scenarios nobody wants, a portfolio dashboard for what you already own, an AI deal advisor for the questions in between, and CFO-style reporting with a bookkeeping suite underneath, so the after-the-deal numbers stay as sharp as the before.

What it proves

That my finance and bookkeeping background isn't a biography detail, it's a build advantage. DealSharp exists because I understand both the spreadsheet and what it's hiding.

Case 03, Studio, conversion system03 / 04

OpsByFabian

The problem

Most freelancer and agency websites are brochures: they describe, they decorate, and they leak every visitor who wasn't already ready to buy. A studio that sells systems shouldn't have a website with no system behind it.

The system

This site, designed as a funnel, not a portfolio. A bilingual conversion path (EN/ES), a diagnostic lead magnet (the Business Leak Scorecard), an intake flow shaped like the start of a project, and copy that qualifies as it persuades. The studio runs on the same method it sells: diagnose, map, design, build.

What it proves

That I practice the positioning I sell: a website should move people into a workflow. You're inside the proof right now.

Case 04, Tool, diagnostic lead magnet04 / 04

Business Leak Scorecard

The problem

Founders feel that something leaks, time, leads, clarity, but can't name it, so they buy tools at random or do nothing at all. “Book a call” asks for trust before giving any value.

The system

A seven-question diagnostic that runs entirely in the browser: rough inputs in, an honest leak profile out, score, risk level, value at risk, and the system I'd build first. It gives value before asking for anything, and it starts the conversation with shared numbers instead of a blank page.

What it proves

That diagnosis can be productized. The first step of the OpsBuild Method, find the leak, works as software, too.

What you won't find here

Invented revenue charts, rented client logos, or testimonials written by me in three different fonts. Every case above is a real system I designed and built. Specifics, numbers, and references happen live, on a call, where I can back them.

The next case on this board could be your workflow.
