Shailendra Kumar Y.

I help startups, founders, and businesses build reliable iOS and Flutter mobile applications—from MVP development and feature enhancements to API integration, testing, and App Store or Google Play release. With 8+ years of mobile-app development experience, I have worked on SaaS products, AI-enabled applications, healthcare solutions, booking systems, on-demand services, business apps, and custom enterprise platforms. My focus is not just on building screens. I help turn product requirements into stable, user-friendly mobile experiences that are designed to scale as your business grows.

Clients work with me for clean and maintainable code, dependable delivery, clear communication, and long-term support when their product needs to grow after launch.
