About

I’m Piyush Shrivastava, a software and mobile developer focused on building reliable, user-friendly apps using React Native and JavaScript (ES6+). Over the years, I’ve worked on end-to-end development—from implementing Redux-based state management and integrating APIs/payment flows to delivering responsive UIs and handling deployment to app stores.

I enjoy collaborating with cross-functional teams, improving existing systems, and strengthening code quality through reviews and best practices. Recently, I’ve led engineering work at HCLTech in Pune while also delivering multiple mobile projects (including healthcare, delivery, secure file transfer, and land management solutions), ensuring smooth functionality, performance, and modern features like push notifications, background tasks, and encryption where needed.

Note on testimonials: the projects in my portfolio were delivered while working under organizations (HCLTech, CDN Solutions Group, AveryBit Solutions) and for clients through those companies, so client feedback was given to the organization rather than to me directly. I’m happy to share references or do a short paid trial task.

During this time I worked on client projects through CDN, including Sensand, a land management app for an Australian client (React Native, Expo, Mapbox, Zustand), and took part in code reviews. These projects were delivered for clients through the company, so this letter serves as my reference for that period.
