What we build

Three things, properly.

Custom mobile apps, bespoke software, and modern websites for South African businesses. We work with a tight roster of clients each year so the principal engineer is involved in every project from architecture through launch.

01

Mobile App Development

Production mobile apps for iOS and Android, built once on Flutter or React Native and deployed to both stores. Real backends, real databases, real auth, and real-world workflows. Not prototypes — apps that ship to clinics, retailers and customers across South Africa and run every day.

Deliverables

  • iOS + Android from a single codebase
  • Native module integration where it matters
  • Custom backend or Firebase/Cloudflare suite
  • Authentication, role-based access, secure storage
  • Push notifications and in-app messaging
  • App Store + Play Store submission and review handling
  • PDF generation, document handling, offline mode
  • Analytics, crash reporting, ongoing support

Best for

  • Healthcare practices that need a clinical workflow tool
  • Retailers replacing spreadsheet-driven operations
  • Founders shipping a consumer app to the SA market

Stack

  • Flutter
  • React Native
  • Firebase
  • Cloudflare Workers
  • Riverpod
02

Custom Software Solutions

Bespoke software for businesses outgrowing spreadsheets, off-the-shelf SaaS combos, and the limits of generic platforms. We build the system you actually need — not the closest one we can configure. From clinical consultation tools with AI-driven transcription to multi-location inventory and operations dashboards.

Deliverables

  • Discovery and architecture design
  • Custom backend (Node, Python, Cloudflare Workers)
  • Web admin dashboards built on Next.js
  • Authentication and granular role-based permissions
  • API design and third-party integrations
  • AI/ML integration where it adds real value
  • Database design (PostgreSQL, D1, Firestore)
  • Deployment, monitoring, and ongoing iteration

Best for

  • Practices and operators with workflows no SaaS fits properly
  • Teams that have outgrown a Google Sheets + Zapier setup
  • Founders building something that needs to scale technically

Stack

  • Next.js
  • Node.js
  • Python
  • PostgreSQL
  • Cloudflare Workers
  • Firebase
03

Website Development & Design

Custom websites that load in under two seconds on mobile and stay that way. We don't theme WordPress — we write production code on modern stacks (Next.js, React, Cloudflare's global edge) so the site is fast, reliable, and ours to evolve. From single-page brochures to full ecommerce stores running on our own custom platform.

Deliverables

  • Custom design — not a template you pay to remove
  • Next.js + React on Cloudflare's global edge
  • Mobile-first responsive layouts
  • On-page SEO, schema markup, sitemap, robots, llms.txt
  • CMS or admin dashboard if you need to update content yourself
  • Performance budget — Core Web Vitals in the green
  • Migration from WordPress, Wix, Squarespace, Webflow
  • Ongoing hosting and maintenance

Best for

  • Established businesses tired of slow WordPress sites
  • Startups that need their site to feel like the product
  • SA retailers ready to take ecommerce seriously

Stack

  • Next.js
  • React
  • Tailwind
  • Cloudflare Workers
  • Drizzle ORM

Also in the studio

A custom ecommerce platform.

Beyond the three core services above, we also run our own custom ecommerce platform — already powering Victoria Packaging, Cell Trader, and Bargain Home. Transparent pricing, marketing automation built in, and zero platform surcharge on sales.
