I'm Karrar, a full-stack developer in London.I build things for the web, front to back, and try to do it properly.

I built it as a home for my client and demo projects, and as a pitch in its own right. Rather than describing what I can build, each service lets a prospective client try a working example, so they can judge the quality before we've even spoken.

• Demos of each service that build themselves, then become interactive.

I built and delivered Blood Test London for a client whose clinic never went into business, so the site never went live. Wimpole Wellness is that work rebuilt as a full demonstration. Patients rarely know the names of blood tests, so instead of a catalogue of 390+ tests, it starts from their concerns or their GP's form.

• Pip, an AI assistant that suggests tests or packages from a patient's concerns.
• Upload a GP form and AI pulls out the tests requested.
• A complete booking system with real-time availability, synced to the clinic's diary.

A UK charity that could only take donations by bank transfer. I implemented online giving, learning WordPress and PHP to do it.

• Single and monthly donations by card, Google Pay or PayPal.
• Redesigned appeal pages.
• A separate Shopify merch store, handed over so staff run it themselves.

The clinic's old site was basic and dated, and it didn't earn patients' trust. I rebuilt it from the ground up as a modern, polished site with online booking at its core.

• Online booking by department, service and live time slot, with same-day appointments seven days a week.
• Secure Stripe payments, with every booking synced straight to the clinic's Google Calendar.

A concept store for a tea brand built around the Tea Crate, a monthly subscription box of themed artisanal teas. I learned Blender for it, modelled and animated the 3D myself, and brought it into the browser with Three.js.

• 3D tea tins that rise on pillars in the hero, then open on hover to reveal the tea.
• A 3D subscription box that opens as you scroll, its contents drifting out and settling onto the table.

A booking site for a premium car detailing business. I built it to show a prospective client that I could build a proper booking system, before they hired me.

• Enter a registration and the MOT History API fills in make, model and colour, so customers skip the vehicle picker.
• A step-by-step booking flow, from vehicle to package to time slot.
