Hi, I'm Yushir. I build small websites and tools, and then I try very hard to break them.
I've spent over a decade finding where software breaks. In the evenings and on weekends, I build useful things for people and small businesses: a simple site, a quote calculator, a little app that replaces a messy spreadsheet.
Free South African calculators for fuel, electricity, home loans, public holidays and more. Every figure links to its official source and date, and every calculator is covered by automated tests.

A private, phone-first app for planning our own wedding: tasks, appointments, suppliers and documents in one place. It saw real use, every day, right up to the big day.
Built to make a house hunt less chaotic: save listings, sort and filter them, and track who you've called and what you've viewed, instead of juggling links in a chat thread.
Not for hire, just for the joy of it. This is where most of my learning happens.
A text adventure in the old DOS spirit: a cyberpunk-noir mystery told in ASCII, with jokes on top and something sadder underneath.
A tiny medieval village that runs itself. The residents work, eat, chat and remember, and the stories come from the systems, not a script.
A little pet that lives in the browser. Feed it, clean it, play with it, and it slowly grows up.
A clear, fast site that tells people what you do and how to reach you. Works well on any phone, even on slow data.
Let customers work out a rough price or answer before they call you, so the conversation starts further along.
Bookings list, stock count, job tracker: one thing done well, in place of the spreadsheet everyone is scared to touch.
Already have a site? I'll test it the way I'd test software for a living, and give you a plain-English list of what's broken, slow or confusing.
I keep things small so I can do them well. I'm not the right person for online shops or anything that takes payments, apps with lots of user accounts, "the next big platform", rush jobs, or round-the-clock support. If that's what you need, I'm happy to point you somewhere better.
Not the solution, the problem. Use the box below, or WhatsApp me.
What I'll build, what I won't, how long it should take and what it costs. Site check-ups are R1,800, and new websites start from R6,500.
You see real progress every week or so, and can steer before anything is set in stone.
I test it properly, show you how it works, and you own it. Most small projects take a few weeks.
I build with AI coding tools, and I'm upfront about that. It's a big part of why a small project doesn't need to cost a fortune. But code that runs isn't the same as code that does what you need, every time. Over ten years in software quality has taught me where things quietly go wrong, so I decide how it's put together, I test it properly, and I don't hand over anything I wouldn't trust myself.
Three quick questions, so we both know early whether I'm the right person.
I'll reply within 3 working days. A copy has gone to your email.
