Mahin K. H.
I design, build and run websites and web apps for businesses - from a simple site that brings in customers to custom tools, dashboards and online payments. One person, start to finish. Based in London, UK, working with clients anywhere.
// SERVICES
Whatever stage you are at, I can take it from idea to a live, working product - and keep it running after launch.
Web Design
Clean, modern page designs and layouts made around your brand and your customers. See and approve exactly how every page looks before anything gets built.
Layouts · mockups · mobile-firstLogo Design
A distinctive logo and simple brand kit - colours, fonts and icon versions - so you look consistent on your website, socials, signage and print.
Logo · colours · brand kitBusiness Websites
Fast, mobile-friendly sites for shops, restaurants, clinics and studios. Menus, opening hours, booking and order links, contact forms - easy for customers to find on Google.
e.g. Merton Fish BarWeb Apps & MVPs
Have an idea for a product? I build the full thing - user accounts, database, admin area, emails - so you can launch, get real users and grow from there.
e.g. SourceBritain, CID JournalDashboards & Internal Tools
Replace spreadsheets with a private tool built around how you work: daily sales, expenses, stock, bookings or reports, with clear numbers by day, week, month and year.

Take payments, sell products or run subscriptions online. I have spent years building payment systems professionally, so checkout, refunds and payouts are done properly.

// ABOUT
I am a software engineer with 6+ years of experience building products used by thousands of people and systems handling millions of requests a day. I have done this at companies like Checkout.com, Beamery and GetGround, mostly on payments and data-heavy products.
Now I bring that same standard to small businesses and founders. You work directly with me, not an agency: one point of contact who designs, builds, launches and looks after your project.
