Professional Profile
I'm Rajneshwar Singh—a dedicated backend developer and Node.js expert with over 8 years of experience
in building robust, scalable systems that power modern web applications. My technical expertise spans
Node.js, Express.js, Nest.js, GraphQL, and Fastify.js, complemented by hands-on experience with
PostgreSQL, MySQL, and MongoDB. I specialize in designing efficient architectures and crafting reliable
APIs that not only meet but exceed
expectations in both functionality and security.
I've had the privilege of delivering high-performance backend solutions, including complex event
management platforms
and systems built on microservices architecture, while leveraging AWS services such as S3, EC2, Route53,
Api Gateway, Cloud Watch and Lambda. My
passion lies in optimizing backend performance to ensure every project is both innovative and
dependable. With
successful projects delivered for clients in the US and internationally, I bring precision, innovation,
and
dependability to every endeavor.
Beyond my technical skills, I have a proven track record in project leadership, guiding cross-functional
teams in Agile
environments from inception to completion. I excel in communicating with both technical and
non-technical stakeholders,
ensuring seamless project progression and alignment with business goals. Whether you're looking to
enhance an existing
system or build something entirely new, I'm here to help bring your vision to life.
