Websites and apps, sketch to server.

I’m Yersin, an independent designer and full-stack developer from Kazakhstan. My clients include MADLEN, Sandyq Group and Aq Niet Group, the group behind Europharma. I do the whole job myself, so you explain your project once, to the person who builds it.

Reply to Yersin…
MADLEN’s cake builder in four layers. Pick a size, a shape and a sponge, then open Code or Server.

Selected work

  • MADLEN

    new.madlen.kz

    Result: Orders from the website and the app arrive in the kitchen as real iiko orders, and a new item added in iiko shows up on the site with no code change.

    • UI and website
    • Web app
    • Backend

  • Aq Niet Group

    aqnietgroup.yers.dev

    Result: Every old link still opens the right page, and before each deploy an automated check tests every page for broken links, SEO tags and WCAG 2.1 AA accessibility.

    • UI and website
    • Web app

  • Sandyq Group

    sandyqgroup.yers.dev

    Result: Partner and job applications land in Telegram the moment they are sent, and the whole site is served as static files, with no CMS to keep updated.

    • UI and website
    • Web app
    • Backend

  • Qalta

    qalta.yers.dev

    Result: Qalta is out on the App Store. It has no accounts, and the server stores nothing about anyone: it only serves the app, the public pages and exchange rates.

Services

Hire me for one layer of the job or for all four. Every project gets the same person from the first call to launch.

    UX and prototypes

    Before anything gets built: user flows, wireframes and a clickable prototype, so you see the product work before paying for code.

    • Clickable prototype in Figma
    • Every page and state mapped out
