I build sites and look after them for years.

I’m Serhii Nadolskyi, a senior full-stack web developer. I work for web agencies, white-label under their name, and directly for companies. Since 2018 I have built and run sites for companies in Germany, Israel, the UK, Switzerland, the USA and Australia.

Some of them: a crypto exchange’s marketing site, a 3D virtual museum, a Swiss insurtech platform, a UK publisher’s network of sites, manufacturers’ sites and shops.

On most of these projects I was the only developer, or the main one. That shaped how I work. I take a job from the design file, or from someone else’s code, all the way to production. And I stay to look after it.

How I work

Before I touch a working site, I make a backup and a copy. You click through the copy, and it goes live only after your OK. If something is fragile, or will take more than we thought, I tell you before going further. The call is yours.

I keep the setup simple, and every part I add has a clear job. When the site is done, your editors run it themselves. If it helps, I record short videos showing how.

Where I have worked

• CGSpark, a web and mobile studio in Tel Aviv, since 2018: main developer of eToroX’s marketing site, eToro campaign pages, a 3D virtual museum, and sites and apps for the studio’s other clients. In 2022 full-time, including hiring and mentoring.
• German web agencies. Since 2023 I have worked white-label for them, often as the only developer on the project. That’s 40+ of their client companies: manufacturers, pharma, retail, the public sector.
• Direct clients. ExpertSure & Ecopreneurist (UK), MDN Group, Auto3P (Switzerland), and Upwork clients since 2018. Top Rated, 100% Job Success.

The SN mark is a lighthouse, because I’m from Odesa, by the sea. It’s green because green is my colour.
