01
What teams in the United Kingdom bring me
Your platform has grown faster than its architecture, and every release now carries risk.
Slow pages and poor Core Web Vitals are costing you search traffic and conversions.
You need to show that personal data is handled properly under UK GDPR, with the right terms for every processor.
02
Working with teams in London
A UK morning falls in my afternoon, so a daily stand-up early in your day is easy. When British Summer Time starts or ends, the shared window shifts by an hour; the table on this page always shows the current season. Each day closes with a short written update.
Each city's 09:00–18:00 working day on the clock in Mumbai (UTC+5:30), in January and in July, so daylight saving is accounted for.
| City | In January | In July |
|---|---|---|
| LondonUTC+0 / UTC+1 | 14:30–23:30 | 13:30–22:30 |
The rules that apply here: UK GDPR and the Data Protection Act 2018 · Data (Use and Access) Act 2025 · Off-payroll working rules (IR35)

City pages for the United Kingdom
London
England, UK
A freelance senior software engineer working remotely from Mumbai for London scale-ups and agencies, with your whole morning in my afternoon. It is for Laravel and Next.js platforms that outgrew their first build, AI features and technical decisions that need an independent view.
Manchester
England, UK
A freelance senior software engineer who modernises PHP applications in stages, working remotely from Mumbai for Manchester agencies, with your morning in my afternoon. It is for Laravel apps to upgrade, CodeIgniter or bespoke PHP to replace, and sites that must get faster without a rebuild.
Edinburgh
Scotland, UK
A freelance senior software engineer who builds SaaS, fintech and data products and starts with a security review, working remotely from Mumbai for Edinburgh teams on UK time. It is for teams where a security review is part of every enterprise sale.
04
Contracts and invoicing in the United Kingdom
Invoices in pounds sterling, monthly or per milestone, paid through Wise or Payoneer. I can work under your services agreement, plus a data processing agreement wherever I handle personal data.
Tax and legal treatment depends on your company and country: confirm it with your accountant or counsel.
05
Data protection and the rules that apply
UK GDPR and the Data Protection Act 2018
Lawful basis, records of processing and processor contracts. The engineering: data minimisation, access control, retention, and subject-access requests that can be answered in days rather than weeks.
Data (Use and Access) Act 2025
It became law on 19 June 2025 and amends UK GDPR, the Data Protection Act and the cookie rules, with its changes phased in over the following year. The Information Commissioner's Office explains what applies today; I design so changes like these are cheap to absorb.
Off-payroll working rules (IR35)
They apply when a worker provides services to a client through their own intermediary, usually a limited company, and would have been an employee if engaged directly. In most cases the client decides the worker's employment status; a small private-sector client leaves it to the worker's intermediary. Whether they touch an engagement with me is for your accountant to confirm.
This is engineering guidance, not legal advice: confirm what applies to your business with your counsel.

Questions from teams in the United Kingdom
Is working with someone in India a restricted transfer?
It is: remote access from India counts as one. Your personal data stays in your UK systems, the International Data Transfer Agreement or the UK addendum in our data processing agreement covers the access, and I use anonymised or synthetic data where I can. Confirm what applies with your counsel.
Will you sign a data processing agreement?
Where I handle personal data, the engagement includes one: yours, or a standard agreement we review together.
How much of the working day do we share?
Most of your morning. The overlap table on this page shows the exact hours for the current season.
Which contract do UK clients sign?
Usually your own services agreement, with a statement of work per project; I can also work under mine. Wherever I handle personal data the engagement adds a data processing agreement, and the International Data Transfer Agreement or the UK addendum covers the access from India. Invoices are in pounds sterling, monthly or per milestone, paid through Wise or Payoneer. The guide to working with an engineer in India lists the clauses I make sure exist, and your counsel decides the wording.
Do the off-payroll rules (IR35) apply to a contract with you?
They can apply when a worker provides services through their own intermediary, usually a limited company, and would have been an employee if engaged directly. In most cases the client decides the worker's employment status, and a small private-sector client leaves it to the worker's intermediary. Whether the rules touch an engagement with me is for your accountant to confirm; HMRC's guidance on off-payroll working is the source.
Do you build UK platforms in Laravel and Next.js?
Yes. Laravel is my main stack, and I build front ends in Next.js. When a platform has outgrown its first build, an architecture review or a performance audit usually comes first, so the choice between rebuilding and refactoring rests on a written report. The London page shows how that works for a scale-up.
