Photo-RX

Photo-RX was a 2 kW, high-throughput, current-controlled POWER-LED system developed in 2020–2021 at ICIQ, within Dr. Julio Lloret-Fillol’s innovation group and tied to the start-up Treellum Technologies.

My role

I designed the digitally-controlled constant-current power electronics for the LEDs and the main motherboard engine, including the architecture and IC interfacing (SPI, I2C) for DACs, ADCs and PMICs. I also designed the low-voltage power supplies and the IoT/UX layer, with Bluetooth and Wi-Fi running on ESP32 and STM32F1/F4 microcontrollers.

Outcome

It was a formative start-up experience that fuelled my passion for entrepreneurship. After I moved on to Lear, the prototype was commercialised in 2022, led by my colleague Mykola Lazoryshyn.

Status

Past project — 2020–2021.

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.
