Software that fits.
Built to last.
Off-the-shelf tools force your organisation to adapt to their limits. SquareX designs and builds custom web, mobile and enterprise software — engineered around your processes, your users and the long term.

When standard tools stop fitting, build what fits.
Custom software is not about novelty — it is about fit. When your systems mirror how your organisation actually works, efficiency follows. When they fight it, every workaround costs time and money.
SquareX builds software the way it should be built: modern architecture, automated testing, clean code and honest documentation — so the system remains an asset years from now, not a liability everyone is afraid to touch.
Can your organisation answer these with confidence?
- Do your processes bend around your software — instead of the reverse?
- Are critical workflows still running in spreadsheets?
- Can your current systems scale with your ambitions?
- Do you fully own your code, data and deployment?
- Is technical debt slowing every new feature?
- Could your software itself become your competitive advantage?
What does the service cover?
Full-cycle software development — from discovery and design through engineering, launch and continued evolution.
Web Application Development
Responsive, secure web applications — from customer portals to internal operational systems.
Mobile App Development
iOS and Android applications built for performance, usability and long-term maintainability.
Enterprise Software Solutions
Systems for core operations: workflow, case management, ERP extensions and line-of-business tools.
API Development & Integration
Well-designed APIs and integrations that connect your systems cleanly and document themselves.
Microservices Architecture
Modular, scalable architectures that let teams ship independently without breaking each other.
Legacy Modernisation
Phased migration away from ageing systems — modernising without stopping the business.
User-Centred Design
Interfaces shaped by real user needs — prototyped and tested before they are engineered.
Automated Testing & QA
Test suites and CI pipelines that catch regressions before your users do.
Documentation & Handover
Clear documentation and knowledge transfer — you are never locked into us, or anyone.
What you receive
You receive working software and the means to keep owning it — not a black box.
Working Software
Production-quality releases delivered in short iterations — visible progress from the first weeks.
Architecture & Technical Design
Documented decisions that keep the system understandable to every engineer who follows.
Quality Assurance Pack
Automated tests, code review standards and release checklists built into the pipeline.
Deployment Pipeline
Repeatable, low-risk releases to staging and production — configured, not hand-crafted.
Documentation & Training
User guides, developer docs and hands-on transfer so your team can run and extend the system.
A transparent approach to building software.
Short iterations, working software early and honest communication — you see real progress every sprint.
Discover
Requirements, users, constraints and success criteria established before any code is written.
Design
Architecture, UX and a realistic delivery plan — agreed and documented.
Build
Iterative development with working demos every sprint and quality gates throughout.
Support
Launch, monitoring and continuous improvement — we stay after go-live.
One partner from idea to production.
SquareX covers the full engineering spectrum — UX, frontend, backend, data, cloud and DevOps — under one roof. Fewer handovers, one accountable partner, and software that actually reaches production.
UX & Interface Design
Prototypes, design systems and usability testing
Web & Mobile Development
Modern frameworks, responsive and fast
Backend & APIs
Scalable services and clean integrations
Data Engineering
Models, pipelines and reporting
Cloud & DevOps
Deployment, monitoring and scaling
Security & Quality
Secure coding, testing and reviews
Senior engineers. Modern stack.
SquareX builds on proven, mainstream technologies — React, Node.js, Python and leading cloud platforms — selected for longevity and your team’s ability to continue the journey.
Have a system that should exist — but doesn’t?
Whether you are replacing a legacy system, digitising a manual process or building a completely new product — start with a scoping conversation about requirements, approach and realistic timelines.
Software delivery is governed by individual agreements covering scope, timeline, intellectual property and support. Estimates are refined through discovery and iterative delivery.
