About me

From problem
to solution,
simple and clear

I'm Joaquín. I work on app development, websites, and process automation. Before writing a single line of code, I sit down to understand the problem: where time is being lost, which task gets repeated by hand, and what's quietly costing a business money.

From there I build the simplest solution that actually solves it — it could be a custom website, an app, or a script that does in seconds what used to take hours.

What I can
solve

Process
automation

If there's a task that gets repeated by hand every day, it can probably be automated. I map out the process, find the bottleneck, and solve it with a script or a custom tool.

Web development

Custom business sites, catalogs, and online stores. Fast, responsive, and easy to maintain.

Custom apps

Applications built for one specific business need — no bloated features or licenses you'll never use.

Excel & data

Optimized spreadsheets, formulas, macros, and dashboards that show at a glance what used to take digging to find.

Get in touch

Integrations

Scripts that connect systems that don't talk to each other, so you stop entering the same data twice.

Before proposing anything, I listen to how things work today: who does what, how often, and where it gets stuck. Half the solutions show up in this conversation alone.

I put numbers to the process: hours per month, errors per entry, the cost of redoing work. That makes it clear what's worth automating first — and what isn't worth touching.

You don't always need a full system. Sometimes a script or a well-built spreadsheet is enough. I propose the minimum that actually solves the problem, and tell you what to expect from each option.

I build in stages and show progress from the start, so we can course-correct before a change gets expensive.

I deploy it, test it under real conditions, and document everything. If you want to change something later, the code is organized so you can.
