About

Engineer by training, entrepreneur by nature.

I'm Carlos Agorreta — an electronics engineer and entrepreneur who turns ideas into elegant, functional hardware and software products. I've spent over a decade between electronics labs, automotive R&D and building my own ventures.

My story

A decade from soldering irons to startups

My path hasn't been a straight line — and that's the point. From importing football jerseys as a teenager to validating automotive electronics in professional labs, every step added a layer: business sense, deep engineering, and the drive to build products end to end.

Career timeline

The path so far

2012

First business — jersey import

Tarragona

As a high-school student I launched a small NBA and football jersey business with a classmate, importing from China through Alibaba and Western Union — real dropshipping, years before AliExpress.

2012 – 2014

Business Administration

Universitat Pompeu Fabra (UPF)

Two years studying Business Administration, where I threw myself into several student associations and learned how organizations actually work.

2014 – 2019

Electronics Engineering

Universitat Rovira i Virgili (URV)

I switched degrees to follow my real passion — electronics — and graduated as an Electronics Engineer.

2020 – 2021

Photo-RX — embedded R&D

ICIQ · Dr. Julio Lloret-Fillol's group

I led the hardware and embedded design of Photo-RX, a 2 kW current-controlled power-LED system: motherboard, digitally-controlled constant-current power electronics, DAC/ADC/PMIC interfacing over SPI/I2C, and the BLE/Wi-Fi UX on ESP32 + STM32. The MVP that lit my passion for entrepreneurship.

2021 – 2024

Hardware Engineer

Lear Corporation

I joined a professional electronics lab doing high-level validation and signal integrity on automotive ECUs — Body Control Modules for JLR and BMW — and won several internal 'Best Kaizen Idea of the Month' awards.

2024 – 2025

Test Lead Engineer

IDIADA

I led test campaigns for EV modules, discovered the latest AI breakthroughs and started writing software to automate my work. I proposed and got ICAT approved — an automotive innovation testing suite with a five-figure budget — just before leaving for entrepreneurship.

2026

Founder & independent builder

Agorreta.eu

Now I build my own products — Factusync, an invoicing app for small businesses, plus several modern websites — and take on new embedded-systems projects.

Photo-RX

Granted by AGAUR and later commercialized in 2022. The project that turned my engineering into a passion for building products.

What I value

Principles I build by

Work directly with you

No layers, no account managers — you work straight with the engineer building your product.

End to end

Hardware, firmware and software under one roof, so nothing gets lost between teams.

Engineering rigor

Lab-grade validation habits from automotive, applied to every product — big or small.

Curiosity & iteration

I keep learning — from power electronics to AI — and fold it back into better products.

What does working with you on a project look like?
Every project starts with understanding your goal, your users and your constraints. From there I handle design, development and delivery myself - whether that is a website, a PCB or the firmware in between - and keep you involved at each milestone.
Mostly small businesses, founders and startups. I like projects where I can work directly with the person behind the idea and move fast, without unnecessary bureaucracy.
Yes. Alongside web and software work I design custom electronics and embedded systems - PCBs, IoT devices and ESP32/STM32 firmware - from a first prototype to production-ready hardware.
On the web: WordPress and custom code, with WooCommerce and Stripe for e-commerce. On hardware: schematic and PCB design, ESP32 and STM32 firmware, SPI/I2C interfacing, and lab-grade validation.
Yes. I stay involved after launch for updates, fixes and improvements - and for hardware, for revisions and scaling to production. You will not be left on your own.
