Discovery and scope - the systems, data, access and constraints. You approve the written scope before design starts. 2. Design and prototype - wireframes, then a clickable prototype. Nothing is built until you sign it off. 3. Build - delivered in increments on a staging URL, reviewed by the engineer who owns the code. 4. Test, launch and hand over - documentation ships with the build, so your own team can run it. You accept before go-live. ## What we do not claim No search ranking position or AI citation is guaranteed - by Codexlava or by anyone, because no search engine or assistant sells one. There are no client names, logos or testimonials on the site because there are none that can be published yet. ## Where we work United Kingdom. ## Contact Email: enquiries@codexlava.co.uk Phone: +44 7493 639381 Address: 182-184 High Street North, East Ham, London E6 2JA, United Kingdom Book a consultation: https://calendar.app.google/VjijBSSeJsREndsV8 ## Key pages - Software Solutions: https://codexlava.co.uk/software-solution - AI integration: https://codexlava.co.uk/ai-integration - Mobile app development: https://codexlava.co.uk/mobile-app-development - MVP development: https://codexlava.co.uk/mvp-development - Web development: https://codexlava.co.uk/web-development - SEO and AI visibility: https://codexlava.co.uk/seo-ai-visibility - Data Analysis and Visualisation: https://codexlava.co.uk/data-analysis - Digital Marketing: https://codexlava.co.uk/digital-marketing - About: https://codexlava.co.uk/about - FAQ: https://codexlava.co.uk/faq - Contact: https://codexlava.co.uk/contact-us ## Guides - How Much Does a React Native App Cost in the UK?
