We plan, design, build and launch mobile apps, websites and business software for startups and companies across Delhi, Noida, Greater Noida, Gurgaon, Ghaziabad and Faridabad. Clear scope, a fixed quote for the first version, weekly demos and support after launch.
Engineer Codewala is based in Greater Noida and works with businesses across Delhi NCR. NCR is not one market: Gurgaon is dense with SaaS startups and corporate teams, Noida has IT and product companies, Delhi has traders, D2C brands and service businesses, Ghaziabad and Faridabad have large manufacturing and education sectors, and Greater Noida and Noida Extension are growing residential and institutional hubs. We shape each project around that context.
Across NCR we build Android and iOS apps, websites and ecommerce stores, custom software such as CRM and ERP, admin dashboards and backend APIs, and startup MVPs. Most work runs through shared documents, weekly demos and calls, so location never slows delivery — and clients who prefer meeting in person are welcome at our Greater Noida office.

View case studiesWe understand your users, must-have features, budget and launch date — on a call, a video meeting or at our Greater Noida office.
You get a feature list, screens, milestones and a fixed quote for the first version, so the budget does not change halfway.
Key screens are designed and shared as a clickable prototype you can try on your own phone before development starts.
App, backend and admin panel are built in short sprints. You see a working build every week and have one point of contact.
Testing on real devices, then release on the Play Store, App Store or your server under your own accounts. You own the code.
Bug fixes, OS updates and new features on a simple monthly plan.
Cost depends on the number of user roles, platforms (Android, iOS, web or all three), the backend and admin panel, integrations like payments and maps, and how custom the design is. A focused MVP costs much less than a full marketplace. After a short call we share a fixed quote for the first version, split into milestones.
