About

Professional summary

I am an Associate Tech Lead / Senior Software Engineer with over 7 years of experience building scalable web, backend, mobile, and cloud-based software solutions. I focus on designing maintainable architectures, improving engineering standards, and delivering reliable products across enterprise healthcare, ERP, marketplace, LMS, e-commerce, mobile, and blockchain domains.

I have strong hands-on experience with Node.js, Express.js, React, Next.js, Angular, TypeScript, PHP, MongoDB, MySQL, REST APIs, and AWS services. My work often involves system architecture, cloud integrations, performance optimization, secure application development, and API design for complex business workflows.

In my recent roles, I have developed and maintained backend services, implemented asynchronous processing with AWS SQS and AWS Lambda, and built AI-assisted workflows to improve internal productivity. I also work on database schema design, integration workflows, and scalable application patterns that support long-term maintainability.

I have contributed to cross-platform mobile applications using React Native, Flutter, Expo, and Dart, integrating them with backend services and third-party platforms. I enjoy turning business requirements into technical specifications, UI prototypes, and production-ready features while keeping usability and performance in mind.

My project experience includes healthcare workforce management, vehicle aftercare booking systems, ERP integrations, construction management apps, travel booking engines, service marketplaces, online examination platforms, and student portals. These projects have strengthened my ability to work across the full stack and adapt to different product and operational needs.

I am also comfortable with DevOps and cloud tooling such as AWS, Nginx, PM2, Ubuntu Server, CI/CD basics, monitoring, and deployment workflows. I value clean code, collaboration, and practical engineering decisions that help teams ship dependable software efficiently.
