Web App Development · Sheffield · Canarlo, Leeds
Web app development for Sheffield's manufacturers, engineering firms, and spinouts — under an hour from Leeds. MVP-to-production hardening, and quoting apps that read an engineering drawing. From £12,500.
Working in Sheffield
A Sheffield spinout's grant-funded prototype often impressed the committee and now has to survive real customers — security patterns enforced on every table, evals gating any model behaviour, infrastructure moved into accounts the founders actually own. We take that MVP to production rather than starting again from zero.
For manufacturers the build looks different: quoting apps that read engineering drawings and past job history instead of a rep's guesswork, and inspection-data apps that make defect records queryable instead of buried in a shared drive. Production-grade, scoped from £12,500.
On-site from Leeds
Sheffield is under an hour from Leeds by train. On-site works the way it should: kickoff on your shop floor or in your lab, because the process we're automating is usually visible from there. Regular in-person reviews are easy to sustain at this distance.
Delivery itself runs remote-first — weekly demos on a real preview URL, readable diffs, UK office hours. The engineer who writes the proposal writes the code and takes the call when something breaks.
What you get
The full detail — scope, process, pricing — lives on the service page. It covers the whole of the UK; /services/web-apps is the place to start.
The key user journey — whatever makes the product useful — built and tested on real data. Not a mockup.
Sign-up, sessions, password reset, TOTP. Per-row security enforced at the database, not just the UI.
The one capability that makes the product worth building, built as a first-class part of the system.
Your Vercel account, your Supabase project, your keys. We deploy and walk off — no agency-held infrastructure.
MVP / Web App from £12,500. Fixed scope, GBP invoicing, no day-rate dance.

A prototype proves the concept; an MVP proves the business. What we build is production-grade — real auth, real data model, real security — not a throwaway you rebuild once it gets traction.
You do. Your repo, your Vercel account, your Supabase project, your keys. No Canarlo SaaS in the loop. The handover doc names every environment variable, cron job and integration.
Start with discovery — two weeks, fixed fee. One scoping call, a written brief, the load-bearing pieces named and the failure modes mapped before anything is built.
Usually, yes — we start with an audit: a structured read of the existing codebase, data model, and security posture, then a written report on what's worth keeping versus rebuilding. You get that report before committing to further work.
