How I work

A clear path from 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.

FAQ

Common questions

Do you work on hardware and software, or just one?

Both. I cover web and software as well as custom electronics, firmware and IoT — which means one partner for a whole product, with no hand-offs between separate teams.

How much does a project cost?

Every project is scoped individually — there are no fixed packages. Tell me your goals and constraints and I'll send a tailored, no-obligation quote.

What technologies do you use?

On the web: WordPress and custom code, with WooCommerce and Stripe for e-commerce. In hardware: schematic and PCB design, ESP32 and STM32 firmware, SPI/I2C interfacing and lab-grade validation.

Do you help after launch?

Yes. I stay involved after launch for updates, fixes and improvements — and, on hardware, for revisions and scaling to production.

Who do you usually work with?

Mostly small businesses, founders and startups who want to work directly with the engineer building their product and move fast.

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.
