From working prototype to production-ready.
Code reviews, security hardening, and infrastructure support for founders who have built an MVP and need a professional foundation under it.
The way software gets built has changed. AI-assisted tools like Cursor, Lovable, Replit, Bolt, v0, and Claude have put real working applications within reach of founders who would never have called themselves developers. The result is a wave of MVPs that genuinely work, and a new question: what now?
We help founders take the next step. The aim is never to rebuild for its own sake. It is to look honestly at what exists, find the gaps that matter, and put the right foundations in place before things scale. The same service supports technical founders who built traditionally and now need experienced eyes on what they have created.
Founders typically come to us at one of a few familiar moments. Something has been built quickly using AI tools and is starting to attract real users. The first paying customer is on the way and there is a quiet worry about whether the application is safe. The platform it was built on no longer fits, and the code needs a proper home. Or the product is growing faster than expected and the cracks are starting to show.
Where we help
Code Audit and Review
A clear-eyed assessment of the application as it stands. What works, what is fragile, what carries risk, and what should be tackled first. Delivered as a written report with prioritised recommendations and plain explanations, so founders understand exactly where their product sits.
Security Hardening
Authentication, authorisation, secrets management, input validation, dependency review, and data handling. The technical groundwork that turns a working prototype into something safe to put in front of paying users. Cross-supported by our dedicated cyber security service where deeper assurance is needed.
Infrastructure and Hosting
Moving off no-code platforms, setting up proper development and production environments, configuring deployments, backups, and monitoring. We operate our own UK-based eco-friendly server infrastructure and advise honestly on whichever option suits the application best.
Performance and Scaling
Identifying the points that will struggle under real-world traffic. Database tuning, caching, query optimisation, queueing, and architectural changes that make growth possible without surprise outages or rising hosting bills.
Compliance and Data Handling
UK GDPR alignment, privacy notices, cookie behaviour, data retention, and the practical paperwork around handling user information responsibly. Sensible measures that protect both the founder and the people using the product.
Ongoing Support
For founders who want a senior technical partner without hiring one full time, We offer ongoing retainer support. Regular reviews, incident response, and a steady hand as the product grows. Where a longer-term technical leadership relationship is the right fit, founders are introduced to the separate CTOMark fractional CTO service.
Most founders begin with a fixed-scope review. We look at the code, the infrastructure, and the security posture, and produce a written report with prioritised recommendations. From there, work usually continues as a hardening sprint, an infrastructure migration, or an ongoing retainer, depending on what the product needs and how quickly it is growing.
We work with founders across the UK and beyond to take MVPs from working prototype to production-ready software. To arrange an initial review, request a callback below.
Frequently Asked Questions
I built my MVP with Cursor, Lovable, Bolt or another AI tool. Can you help?
Yes. This service is designed for exactly that situation. AI-assisted tools have put real working applications within reach of founders who would never have called themselves developers, and the next step is putting professional foundations under what has been built.
Will you rewrite my application?
Only if there is a genuine reason. The aim is never to rebuild for its own sake, it is to look honestly at what exists, find the gaps that matter, and put the right foundations in place before things scale.
What does a fixed-scope review include?
A clear-eyed assessment of the application as it stands: what works, what is fragile, what carries risk and what should be tackled first. Delivered as a written report with prioritised recommendations and plain explanations.
What happens after the review?
Work usually continues as a hardening sprint, an infrastructure migration or an ongoing retainer, depending on what the product needs and how quickly it is growing. You decide which of those is the right next step.
Do you handle hosting and infrastructure as well?
Yes. Moving off no-code platforms, setting up proper development and production environments, configuring deployments, backups and monitoring. FullyCoded operates its own UK-based eco-friendly server infrastructure and advises on whichever option suits the application best.
