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.
