What I'm looking for

I'm looking to build end-to-end web and mobile solutions, including integrations, cloud deployments, performance optimization, and business-critical systems across HR, hospitality, e-commerce, or EdTech.

I've built HRMS, hotel management, and school management products for Mindroid Technology, including payroll aligned with RBI banking salary guidelines, restaurant billing, property management, and mobile learning systems used by 10+ schools.

As an independent developer, I develop React, Node.js, and MongoDB applications, reducing page load times by 40% through query optimization and reusable components. I deploy on AWS using EC2 and S3, establish CI/CD pipelines and monitoring for 99.9% uptime, and build iOS and Android apps with Flutter.
