A senior, independent mobile developer for US founders and product teams. You get one accountable person who designs, builds and ships your app — with daily overlap on US hours.

US agencies often quote six figures and staff your project with whoever is free. Freelance marketplaces are a lottery. siddhesh.studio sits in between: senior-level product design and engineering from one person who stays with your app from the first sketch to the App Store and beyond.
I work with founders and teams across the United States — from pre-seed startups validating an idea to established companies adding a mobile product. Calls happen in your mornings, progress is visible every week, and everything is documented in writing so nothing gets lost.

Daily overlap with Eastern-time mornings and live calls scheduled around Pacific time when needed.

It depends on scope. Most first versions are planned as 6–12 week fixed-scope phases, priced in USD — typically well below US agency rates for the same senior quality. Share your idea for a clear estimate.
There is daily overlap with US Eastern mornings, and I schedule calls around Pacific time when needed. Updates are written up so your team never waits on a time zone.
