Hire a Full-Stack Developer in the UK

TypeScript, Next.js, and Node.js — with 4–5 hours of daily UK overlap.

I'm Waseem Ahmad, a full-stack developer and AI engineer working with remote teams since 2022 — 55+ projects shipped, $155K+ in delivered work, 100% Job Success, and Top Rated Plus standing on Upwork. Remote collaboration from the UK's side is easy because the time gap is small: Pakistan runs just 4–5 hours ahead, so I'm online for your entire morning and into the early afternoon. You work directly with the engineer building your product — no agency layer — with weekly demos and written updates keeping everything visible.

Based in Pakistan (UTC+5, no daylight saving) — 5 hours ahead of GMT and 4 ahead of BST. In UK terms the live overlap runs roughly 9am–1pm in winter and 9am–2pm in summer: your whole morning, every working day.

The challenge

Hiring a senior full-stack engineer in the UK usually means a slow recruitment cycle or an agency margin on every hour. Working with me directly is simpler: one accountable engineer, a scoped written proposal before any commitment, weekly demos of working software, and a response to every message within 24 hours.

Frequently asked questions

How much overlap do you have with UK working hours?
Pakistan is UTC+5 and does not observe daylight saving, so it sits 5 hours ahead of GMT in winter and 4 ahead of BST in summer. In your clock terms that puts the live overlap at roughly 9am–1pm through the winter months and 9am–2pm through the summer — your entire morning, every working day, which covers standups, calls, and pairing. My own morning runs before you start, so there is finished work waiting for review when you come online.
What happens when your day ends and our UK afternoon is still going?
You keep working and I pick it up first thing. Because my morning starts before yours, anything raised in your afternoon is usually answered before you're back at your desk — the practical effect is that UK afternoons behave like the overnight window most distributed teams already plan around. Every message gets a response within 24 hours regardless, and anything genuinely time-critical is worth flagging during the morning overlap so it can be handled live rather than in writing.
How does contracting work for a UK company hiring a developer based in Pakistan?
Two routes, whichever your finance team prefers. A direct services agreement with defined milestones, invoiced on completion, which suits companies with an established supplier onboarding process. Or a contract through Upwork, where escrow and payment protection are handled by the platform — often simpler for a first engagement or where procurement wants a third party in the middle. I work as an independent contractor supplying services, not as an employee. Whether your own off-payroll rules such as IR35 bear on a particular arrangement is a question for your accountant or legal team rather than something I can answer for you — but the engagement structure is deliberately conventional, so there is nothing unusual for them to assess.
Do you quote in pounds, and how does payment work from the UK?
Quotes are issued in US dollars — the starting figure noted below is USD — and the sterling amount depends on the exchange rate on the day you pay, so I won't quote a GBP number that would be wrong by the time you read it. What is fixed is the scope and the price: after the intro call you get a written quote that does not move mid-project. Payment comes by bank transfer, Stripe, or through Upwork, whichever fits your process. Your own VAT treatment on services bought from outside the UK is worth confirming with your accountant, since it depends on your registration status rather than on anything at my end.
How does an engagement start?
With a short intro call — 30 minutes to talk through what you're building and whether I'm the right fit. If we're aligned, you get a written, scoped proposal covering deliverables, architecture, and timeline. I respond to every enquiry within 24 hours.
How does communication work day to day?
Written updates as work progresses, a demo of working software every week, and async-first communication over email or Slack. You always know what was done, what's next, and what's blocking — without scheduling a meeting to find out.
How do contracts and invoicing work?
A straightforward services agreement with milestones, or a contract through Upwork if you prefer escrow and their payment protection. Payment by bank transfer, Stripe, or through Upwork.
Who owns the code and intellectual property?
You do. Full IP ownership transfers to you — source code, documentation, and infrastructure configuration. Repositories are set up under your organisation's control from the start wherever possible.
What does an engagement typically cost?
Most engagements start around $5K; smaller well-scoped work is considered case-by-case. After the intro call you get a fixed, written quote — no surprises mid-project.
