What we build

Six practices, one delivery team. Most engagements combine two or three of these rather than sitting neatly in one box.

Custom Software Development
Bespoke systems built around how your business actually operates, replacing the spreadsheets and manual handoffs that no off-the-shelf product covers.
Internal toolsLegacy modernisationWorkflow automation
Web Applications
Fast, accessible web products built on React and Next.js, from customer-facing portals to operational dashboards used by thousands of staff daily.
React & Next.jsDesign systemsReal-time dashboards
Mobile Apps
Native and cross-platform apps for iOS and Android, designed to work offline and shipped through both app stores with our release process.
React NativeSwift & KotlinOffline-first sync
CRM & ERP
Implementation, customisation, and integration of the systems that run sales, finance, and operations, or a custom build where the platforms fall short.
Salesforce & HubSpotOdoo & NetSuiteData migration
AI Solutions
Practical AI applied to real workflows: document extraction, internal assistants grounded in your knowledge base, forecasting, and classification.
LLM assistantsDocument intelligenceForecasting models
Cloud & API Integration
Cloud infrastructure and the integration work that connects your systems to each other, with monitoring and cost controls in place from day one.

Why Affinux

Built to be handed over, not held hostage

Plenty of agencies can produce a demo. The harder part is a system your team can operate, extend, and audit long after the engagement ends. That is the standard we build to, and it is why most of our work comes from clients who have already been through a project that did not go well.

Talk to an engineer

  • Senior engineers only

    Every engineer on your project has at least six years of production experience. We do not staff projects with juniors and bill them as seniors.

  • Fixed scope, weekly demos

    Work is broken into two-week sprints with a fixed scope and a working demo at the end of each one. You see progress, not status reports.

  • You own everything

    Source code, infrastructure, and IP are yours from the first commit. Repositories sit in your organisation, not ours.

  • Security built in

    Threat modelling, dependency scanning, and penetration testing are part of delivery. We have shipped SOC 2, HIPAA, and GDPR-regulated systems.

  • Transparent pricing

    A detailed estimate before work starts and a fixed price per sprint. If scope changes, we re-quote before doing the work, not after.

  • Support after launch

    Launch is the midpoint, not the finish. Support agreements include monitoring, guaranteed response times, and a named engineer who knows your codebase.

Process

How a project runs

The same five stages on every engagement, so you always know what is happening now and what is coming next.

  1. 01

    Discovery

    1–2 weeks

    We interview your team, map the current process, and agree on what success measurably looks like before anything is designed.

    • Requirements document
    • Success metrics
    • Risk assessment
  2. 02

    Planning

    1–2 weeks

    Architecture, technology choices, and a sprint-by-sprint delivery plan with a fixed estimate you can take to your budget holder.

    • Technical architecture
    • Sprint plan
    • Fixed estimate
  3. 03

    Design & Build

    6–16 weeks

    Two-week sprints, each ending in a working demo on a staging environment you can use yourself. Feedback goes into the next sprint.

    • UI design
    • Working software
    • Sprint demos
  4. 04

    QA & Security

    2–3 weeks

    Automated test coverage, load testing against realistic traffic, third-party penetration testing, and accessibility review.

    • Test coverage report
    • Penetration test
    • Load test results
  5. 05

    Launch & Support

    Ongoing

    Phased rollout, team training, and full documentation handover, followed by a support agreement with guaranteed response times.

    • Deployment
    • Team training
    • Support agreement

Selected work

Three projects, in detail

Each of these replaced a process the client had outgrown. The numbers below are measured against the twelve months before launch.

OperationsCircaflow

Freight operations platform

Circaflow ran a 400-vehicle fleet across nine spreadsheets and a legacy dispatch tool that could not be updated. Dispatchers rekeyed the same shipment three times and had no live view of the fleet.

We replaced the entire stack with a single operations platform: live vehicle tracking, automated route assignment, and a driver mobile app that works through dead zones and syncs when signal returns.

Health & fitnessFitmate

Member companion app

Fitmate's member coaching program depended on phone check-ins that coaches could not keep up with as the member list grew past 30,000. Missed check-ins were only discovered weeks later.

An iOS and Android app for daily habit check-ins, workout reminders, and secure messaging, with a coach dashboard that surfaces at-risk members first.

AI document assistant

Testimonials

What clients say

References available on request. Every quote below is from someone who signed off on the project.

“We had been through two agencies before Affinux and both delivered something that looked right in a demo and fell over in production. Affinux spent the first two weeks in our operations office watching how the job is actually done. The platform has run for two years without a serious incident.”
PR

Priya Raghunathan

VP of Engineering, Circaflow

“Working with member health data usually means a vendor discovering compliance requirements halfway through. Affinux brought them up in the first meeting and built the audit trail into the architecture. Our security review passed without a single finding.”
DO

Daniel Okafor

Chief Product Officer, Fitmate

“The estimate we were given at planning was the number we paid. Scope changed twice and both times we were re-quoted before any work started. After years of software projects, that is genuinely rare.”
