What We Build

Tailored to Your Business.
Not Off-the-Shelf.

Every project starts with your requirements, your users, and your constraints — not a template that sort-of fits.

SaaS Platforms

Multi-tenant cloud applications built to scale from 100 to 100,000 users. We handle architecture, auth, billing integration, and the product experience — you focus on your market.

Corporate Websites & Portals

Performance-optimised, SEO-ready websites that represent your brand with authority. CMS-integrated so your team can update content without touching code.

E-Commerce

Custom online stores built for conversion — not just catalogue display. PIM integration, secure checkout, inventory sync, and post-purchase flows that drive repeat business.

Internal Tools & Dashboards

The apps your team actually uses every day — ops dashboards, workflow automation, approval systems, reporting tools. Built fast, maintained long-term, never abandoned.

Government & Public Sector

Secure, accessible, compliant applications for government bodies and regulated industries. We have delivered for public sector clients and understand the procurement, security, and accessibility requirements.

How We Build

From Brief to Production

No black boxes. No disappearing for months. You see working software every two weeks.

01
01

Discovery & Scoping

We start by understanding your business — not just the feature list. User research, technical constraints, integrations, and a realistic timeline before a line of code is written.

02
02

Architecture & Design

System architecture decisions made upfront: data model, API contract, auth strategy, infrastructure. UI/UX wireframes reviewed and signed off before development starts.

03
03

Agile Build Sprints

Two-week sprints with working software at the end of each. You see progress continuously — not a big reveal six months in. Priorities can shift between sprints.

04
04

QA & Security Testing

Automated test suites, manual QA, and where required — penetration testing and third-party security review. Nothing ships without passing.

05
05

Deployment & Launch

CI/CD pipeline, zero-downtime deployment, monitoring configured, rollback capability in place. Launch is an event, not a prayer.

06
06

Support & Evolution

We don't disappear after launch. Retained development, bug fix SLA, performance monitoring, and feature roadmap support — for as long as you need us.

Why PowerMatt

We Treat Your Product
Like It's Ours

We don't win a project, deliver a codebase, and move on. We build products with the intention of maintaining them — which means every decision we make in build phase, we'll live with in production.

That changes how we code. It changes what corners we won't cut. And it's why our clients keep us on for years, not months.

Security-first by default

OWASP Top 10 addressed in every codebase. Input validation, parameterised queries, CSP headers, HTTPS enforcement — not bolt-ons, built in from day one.

Performance obsessed

Core Web Vitals in the green. Server-side rendering, image optimisation, edge caching, lazy loading — your users notice the difference.

Code you can own

Clean, documented, tested code. No proprietary frameworks that create lock-in. If you ever move it in-house or change vendor, you can — without starting over.

Long-term partnership

Most of our development clients have been with us for 3+ years. We build things to last and stay to evolve them — not win a project and disappear.

Regulatory & compliance ready

GDPR, ISO 27001, Cyber Essentials, GDS standards — we know the requirements and build to meet them, not retrofit compliance after the fact.

Mobile-first, responsive always

Every project is designed and tested across devices. PWA capability, offline-first architecture, and native-grade mobile experiences where the brief demands it.
