A senior software engineer for US teams, with the East Coast morning in common.

A senior software engineer for US startups and product teams, working remotely from Mumbai so that the East Coast morning falls inside my evening. It is for founders and CTOs who need senior engineering without a full-time hire: MVPs, AI features, performance work and rescuing apps built in a hurry.

Cities: New York, Chicago, San Francisco
Work week: Monday to Friday
Invoices: USD
Language: English

What teams in the United States bring me

You need a production-grade first version before your next raise, and hiring a senior engineer full time would take longer than building it.
An app built in a hurry, by an agency, a contractor or AI tools, is now slow, fragile or risky to change, and customers have noticed.
You want AI features that hold up in production, with evaluations and cost control, not a demo that works once.
Enterprise buyers send security questionnaires, and the number of state privacy laws keeps growing.

Working with teams in New York, Chicago and San Francisco

My evening block lines up with the East Coast morning, so a daily call at the start of your day works. With the West Coast the shared window is short, so we plan around it: written updates, recorded walkthroughs and one or two agreed call slots a week. US federal holidays are in my calendar.

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.

Shared hours with New York, Chicago and San Francisco

Contracts and invoicing in the United States

Invoices in US dollars, monthly or per milestone, paid through Wise or Payoneer. I can work under your master services agreement and statements of work, with intellectual property assigned to you, and provide a W-8BEN.

Tax and legal treatment depends on your company and country: confirm it with your accountant or counsel.

Data protection and the rules that apply

State privacy laws

A growing number of states have comprehensive privacy laws, California's being the most developed, and California's regulators treat a browser's Global Privacy Control signal as a valid opt-out. The engineering: a map of personal data, consent and opt-out handling that honours those signals, retention rules, and deletion that really deletes.

SOC 2 and security questionnaires

Not a law, but a condition of many enterprise deals. The evidence buyers ask for (access control, logging, change management, restore-tested backups) is easier to show when it is built in rather than added later.

This is engineering guidance, not legal advice: confirm what applies to your business with your counsel.

Questions from teams in the United States

Can you work US hours?

Partly, and by design: my evening block covers the East Coast morning every weekday. The hours we share go to decisions; the rest of the work runs on written updates you can read on your schedule.

Who owns the code?

You do. The code lives in your repositories and cloud accounts from the first day, and the agreement assigns the intellectual property to you.

How do we start?

With a small, fixed-price first step: an audit, an assessment or a scoping sprint that ends in a written outcome you can use whatever you decide next.

Which US state privacy laws affect my app?

It depends on where your users live and how many of them there are, because each state sets its own scope and has its own regulator. California's regulators treat a browser's Global Privacy Control signal as a valid opt-out, and Colorado and Texas also require covered businesses to honour universal opt-out signals; the Denver and Austin pages give those states' rules with their sources. The guide to US state privacy laws and Global Privacy Control shows what the signal means in code. This is engineering guidance, not legal advice: confirm what applies with your counsel.

How do contracts, invoicing and IP assignment work with a US client?

I work under your master services agreement with a statement of work per project, or under mine. Invoices are in US dollars, monthly or per milestone, paid through Wise or Payoneer, and I can provide a W-8BEN, the form a foreign individual gives a US payer to establish foreign status for tax purposes (IRS: About Form W-8 BEN). Intellectual property is assigned to you on payment, with the code in your repositories from the first day. Tax treatment depends on your company, so confirm it with your accountant; the guide to working with an engineer in India lists the clauses I make sure every contract has.
