Optimise Digital Experiences
App Development
We develop robust, user-friendly mobile and web apps designed to drive engagement and business growth.
How we help
From MVPs to full-scale platforms, we turn product ideas into functional, high-performing apps.
We partner with startups, scale-ups, and internal teams to build custom web and mobile applications, including SaaS platforms, internal tools, customer portals, and mobile-first products. We manage the process end-to-end, from technical scoping to front-end and back-end development, QA, launch, and iteration.
We build using modern frameworks, fast sprints and scalable architecture – so you get clean, maintainable code and a product that grows with you.
Whether you’re starting from scratch or expanding an existing platform, we can serve as your tech partner without the bloated agency model.

What we deliver
Product Strategy & Technical Scoping
We define what to build and how to build it - aligning features, stack and roadmap to your business goals.
Frontend Development
We build responsive, high-performance apps using React and React Native, optimised for speed, stability and scalability.
Backend Development & API Integration
We build secure, flexible backends using Firebase, Supabase or your preferred stack and connect your app to everything it needs to run.
MVP Launch & Feature Sprints
We launch lean MVPs, then iterate in agile sprints - continuously improving based on real-world use and feedback.
QA, Testing & Dev Handoff
We test across browsers and devices, document everything clearly, and support a clean dev handover or ongoing roadmap delivery.
Frequently Asked Questions
1
What kinds of apps do you build?
We build web and mobile apps including SaaS platforms, internal tools, customer portals and operational systems – across industries and user types.
2
Can you build from designs we already have?
Yes. If you’re working with your own designer or TAG’s UX/UI team, we can jump straight into development and collaborate on build.
3
What tech stack do you use?
We commonly use React, React Native, Firebase, Supabase, Contentful and API-first architectures – but we tailor it to your needs.
4
Do you help define what we should build?
Yes. We can lead a discovery sprint to map out user flows, feature scope and MVP planning before we start building.
5
Do you offer post-launch support?
We can continue working on your roadmap with structured sprints – or hand off clean, documented code to your internal team.
6
How long does it take to launch?
Most MVPs take 6–12 weeks depending on complexity. We’ll break your build into sprints and keep progress transparent from day one.
