Full Stack Development in London
One team taking a London project from database through to interface, rather than a front-end contractor waiting on a back-end contractor. For most projects below a certain size this is simply how it should be built — the split only pays off once there are enough people to justify the coordination cost.
Why this comes up
The problem
Splitting a small project across separate front-end and back-end suppliers doubles the meetings and creates a seam where every defect can be blamed on the other side. Nobody owns the outcome end to end.
What you get
What we deliver
- One team owning database, server logic, interface and deployment
- A data model designed against the screens it has to serve, rather than in isolation
- Interface and API built together, so neither waits on the other to be specified
- Automated tests covering the paths that matter, not a coverage percentage
- Deployment pipeline set up from the first week, not bolted on before launch
- Documentation and repository access handed over, with no single point of dependency

Working in London
London
London clients usually come to us because they want senior people actually on their project rather than a large agency's B team, and because Midlands rates buy considerably more delivery per pound.
Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates.

Full Stack Development in London — common questions
- Is one team really enough for a serious build?
- For most business systems, yes, and the coordination saving is real. Once a project needs several people working in parallel on distinct areas, specialists become worth their overhead — but that threshold is higher than most suppliers suggest, because a bigger team is a bigger invoice.
- Do we get someone who is mediocre at both instead of good at one?
- That is the fair concern. In practice the people doing this work have a stronger side and we staff accordingly, bringing in a specialist for the parts that genuinely need one rather than pretending the range is unlimited.
- What technology will you use?
- Usually TypeScript across both ends, because one language removes a whole category of translation bugs and lets the same person move between layers. Where your existing stack or your team's skills point elsewhere, we follow that instead.
- What happens when the project ends?
- You get the code, the repositories and the infrastructure accounts. Whether we keep supporting it is your decision, not something the architecture forces on you.
- Do you work with businesses across Greater London?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout London, including London and the surrounding Greater London area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of London businesses do you usually work with?
- Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates. Beyond that we work across Financial Services, Professional Services, Technology, Media, Hospitality and Retail.
- Do you cover the areas around London?
- Yes — we work throughout London, including Reading, Milton Keynes, Cambridge, Brighton. London is an urban area of roughly 9,000,000+, and we take on work across the wider Greater London region rather than the city boundary alone.
