Who you'll work with

From electronics labs to building my own products

What started as a jersey-import side business in high school in 2012 grew through electronics engineering, power-electronics R&D and automotive validation labs at Lear and IDIADA — and is now a portfolio of products I'm building myself.

  • 10+ years across electronics, firmware and software
  • Work directly with the engineer who builds your product
  • Hardware + software under one roof — no hand-offs

How I work

From first idea to launch

1

Discover

I learn your goals, constraints and budget, then scope the right technical approach.

2

Design

I explore and prototype options — for software and for hardware — to find the best solution.

3

Build

I build with precision: clean code, robust boards and a focus on real users.

4

Launch

We ship to production — deploy the site or manufacture the hardware — and iterate as you grow.

Let's talk

Have a project in mind? Let's build it.

Whether it's a website, a custom board or a full product, tell me what you're working on and I'll help you ship it.

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.
