Full-Stack Python Development in the United Kingdom
Production web apps with a Python backend (FastAPI/Flask) and a modern React/TypeScript frontend — shipped end-to-end by one engineer.
Who this is for
Founders and engineering leaders who want to skip the agency overhead and ship a real product.
What problem this solves
Hiring two contractors (frontend + backend) means coordinating two timelines, two opinions on contracts, and two people pointing at each other when something breaks. A single full-stack Python engineer ships faster and owns the whole stack.
Why this matters specifically in the United Kingdom
UK clients put heavier weight on data governance, ICO compliance, and clear contractual SLAs. Engagements typically use a UK Ltd or NHS Digital procurement framework. We have shipped a production NHS clinical-decision-support platform and a UK visa-sponsorship analytics product.
What you get
- Working SaaS or internal tool, deployed to your cloud
- FastAPI or Flask backend with typed schemas, auth, and migrations
- React + TypeScript frontend (Tailwind + shadcn/ui)
- CI/CD, observability, and a deployment runbook
How the engagement runs
- Design. Whiteboard the data model, the auth model, and the 5 happy-path flows.
- Walking skeleton. Login → core action → success in week one. Unstyled, but real and deployed.
- Build. Vertical slices, weekly demos, no surprises.
- Polish & ship. Auth hardening, observability, performance, runbook, and handoff.
Deliverables
- Source code in your repo with PR-based history
- Backend: FastAPI/Flask + Postgres + Alembic migrations
- Frontend: React + TypeScript + Tailwind + shadcn/ui
- Auth (Supabase, Auth0, Clerk, or custom)
- CI/CD (GitHub Actions → Vercel/Fly/Railway/AWS)
- Sentry-style error monitoring + uptime checks
Outcomes you can expect
- First production deploy in week 1
- Clean, typed code your future team can read
- No 'agency black box' — every commit is yours, every decision is documented

Questions British buyers ask about full-stack Python
- How do you contract with British clients?
- Engaged via UK Ltd contract, IR35 outside (we work as a substitutable supplier, not a personal-services contract), or through agency-of-record arrangements.
- What about regulatory compliance in the United Kingdom?
- We work to UK GDPR + Data Protection Act 2018, ICO registration, NHS Digital DSP Toolkit (for healthcare work), FCA-adjacent guidance (for fintech work). Where audited compliance certifications are required, we partner with the right specialist firm and ship code that meets the technical controls.
- What's the timezone overlap?
- Operates 9am–6pm GMT/BST with strong Pakistan Standard Time overlap (PKT is GMT+5)
- What's a typical full-stack Python engagement size in UK?
- £4,000–£50,000 GBP per engagement, structured against fixed milestones. Hourly engagements are billed at £75–£150 GBP per hour.
- Why pick a full-stack Python developer over a separate frontend + backend hire?
- Speed and accountability. One person making coherent decisions across the stack ships faster than two coordinating handoffs, and there's no 'that's the other team's bug' when something breaks.
- Do you only do FastAPI/Flask, or also Django?
- FastAPI and Flask are the default. We can work in Django if your team already runs it; the patterns translate but Django's conventions add weight that small teams rarely need.
- Can you also do Node.js or Next.js?
- Yes — we've shipped 3000+ Next.js sites in an automation pipeline, and most of our recent SaaS work uses TypeScript end-to-end. Pick Python for ML/data-heavy backends, TS for product-velocity backends.
- Will you work with our existing codebase?
- Yes. We start with a 1-day codebase audit and map our work to your existing patterns rather than imposing ours.
- What about testing?
- Pytest + Playwright for end-to-end. We don't write tests for the sake of coverage — we test the contract boundaries (API shapes, auth, money math) and the flows real users take.
- Do you handle deployments and on-call?
- We set up CI/CD and observability so your team can. Optional 30-day on-call window for critical post-launch issues.
