Portrait of brand designer Kai Marlow

I like making websites that feel a little different and have some personality to them. A lot of my inspiration comes from older internet aesthetics, especially dreamcore and Frutiger Aero - the colours, strange imagery, nature, technology and that optimistic early-internet feeling.

I usually start with an idea or visual that interests me and build from there. Outside of client work, I’m often experimenting with designs, listening to music or making something just because I think it would be fun to try. Away from the screen, I enjoy painting and spending time with my cats.

FAQs

answers for commonly asked questions

contact@williamcostales.com

what can you help me build?

websites, apps, backend systems, apis, databases, and custom software. whatever we build together, i want it to be something we're both proud of.

how long does development typically take?

i'd rather build something properly than rush it. clear and realistic timelines are always given beforehand.

what happens after launch?

i care about how the finished product performs, not just getting it live. i can stay involved with improvements, fixes, and future ideas!

how do we get started?

shoot me an email, we'll talk about your idea and what you want to achieve. from there, we'll figure out the best way forward.

how do you approach a project?

i take on projects i can genuinely give my full attention to. i'll take time to understand and immerse myself into your idea before i start building.

do you use generative ai in development?

never. developing a website, especially with ui/ux in mind, should be done by passionate people with artistic vision, not by a computer. i may use genAI for mockups, but never in the finished product at all.
