The tools behind every build
Five phases from idea to live product
Discovery
User journeys, competitor research, and technical architecture decisions made before a line of code is written.
DELIVERABLE: Scope DocumentArchitecture
System design, data models, API contracts, and clickable prototype. You approve before build begins.
DELIVERABLE: Clickable PrototypeBuild & Test
Two-week sprints with working software delivered each fortnight. 80%+ test coverage on every PR.
DELIVERABLE: Sprint DemosLaunch
Zero-downtime deployment, monitoring live, App Store / Play Store publishing, and Lighthouse audit passed.
DELIVERABLE: Live ApplicationEvolve
Ongoing sprint capacity for new features, performance tuning, or a full support plan — your choice.
DELIVERABLE: Roadmap & RunbooksWhat every project includes
Source Code in Your Repo
All code committed to your GitHub or GitLab org from sprint 1. You own it — we don't hold it hostage.
Automated Test Suite
80%+ unit test coverage and integration tests that run on every pull request via CI. Nothing ships without passing.
CI/CD Pipeline
GitHub Actions pipeline configured for automated build, test, and deployment to staging and production.
Monitoring & Alerting
Uptime monitoring, error tracking (Sentry), and performance dashboards set up before go-live.
Full Documentation
README, architecture decision records, API docs, runbooks, and a handover pack — all written, not promised.
90-Day Warranty
If something we built breaks due to our code within 90 days of launch, we fix it. No charge, no debate.

Answers to the questions we get most
How long does a typical project take?
Most websites and mobile apps take 8–16 weeks from kick-off to launch. We work in two-week sprints, so you see working software every fortnight and can course-correct early — before small changes become expensive ones.
How does the discovery phase work?
We start with a 1–2 week discovery sprint: user journey mapping, technical architecture review, competitor analysis, and a clickable prototype. You approve the scope and wireframes before a single line of production code is written.
What happens if requirements change mid-project?
Because we work in two-week sprints with a backlog you own, changes go into the next sprint rather than triggering a costly change order. We flag scope impact honestly — you decide whether to adjust the timeline or the feature set.
Do you work with our existing development team?
Yes. We frequently work alongside in-house developers, providing senior capacity, code review, architecture guidance, and CI/CD setup. We document everything so your team can maintain and extend the codebase after handover.
Do we own the code and cloud accounts?
Yes, from day one. Repos live in your GitHub or GitLab organisation, cloud accounts are yours, and all infrastructure is provisioned with credentials you hold. We work inside your environment, not ours.
Native, cross-platform, or PWA — which should we choose?
Native (Swift/Kotlin) gives the best performance and device access. React Native or Flutter covers both stores from one codebase and cuts build cost by 30–40%. A PWA is ideal when discoverability and zero install friction matter more than App Store presence. We give you an honest recommendation in discovery.
How do you handle accessibility and SEO?
WCAG 2.2 AA is a delivery requirement — colour contrast, keyboard navigation, semantic HTML, and screen-reader labels are audited before launch. SEO is handled through clean markup, schema, fast Core Web Vitals (we target Lighthouse 90+ on all pages), and structured content.
What does your quality assurance process look like?
Every sprint includes unit tests (80%+ coverage target), integration tests, cross-browser and cross-device testing, automated Lighthouse performance runs, and a manual QA pass before we mark a ticket done. Nothing ships without passing CI.
How are projects priced?
Most projects use a fixed-sprint model: you agree on a sprint scope, we deliver it for a fixed price — no surprise invoices. Discovery sprints are priced separately so you can validate the concept before committing to a full build.
What support options are available after launch?
You can run the application yourself using our handover documentation, or choose a support plan covering monitoring, security patches, performance tuning, and on-call response. Either way the code is yours.
Do you sign NDAs and IP transfer agreements?
Yes. NDAs are signed before any briefing document is shared. IP assignment is written into the project agreement — you own all work product, designs, and code from the moment of delivery.
How do we get started?
Book a free 30-minute discovery call or send us a brief. We reply within one working day with an honest assessment, a rough timeline, and a ballpark sprint cost — no commitment required. Start the conversation →
