Sanjay Mahajan — Backend Engineer

I am a backend developer with over five years of hands-on experience designing, building, and scaling reliable server-side systems for real-world products. My work focuses on creating clean architectures, efficient data flows, and secure APIs that can scale seamlessly as business needs evolve. I have collaborated with startups, small businesses, and distributed engineering teams to deliver backend solutions that prioritize performance, maintainability, and security. From early-stage MVPs to production-grade platforms, I take ownership of backend systems across the entire development lifecycle. What I specialize in: API Engineering: Designing and implementing scalable RESTful and GraphQL APIs with a strong emphasis on performance, versioning, and maintainability. Backend Technologies: Node.js and Python for building robust, production-ready services. Database Architecture: Data modeling, query optimization, and schema design using PostgreSQL and MongoDB. Cloud & DevOps: Deploying and managing applications on AWS, containerization with Docker, and setting up CI/CD pipelines for reliable and automated releases. Authentication & Security: Implementing secure authentication and authorization mechanisms using JWT, OAuth, and industry best practices for backend security. Scalable System Design: Experience with microservices, event-driven systems, and serverless architectures to support high availability and growth. I believe strong backend systems are the foundation of great products. I value clear communication, thoughtful system design, and writing code that is easy to understand, test, and scale. I am always open to connecting with engineers, founders, and teams who are passionate about building high-performance, secure, and scalable backend systems.
