Background

About Harshit Pratap Singh

I'm a Backend Engineer passionate about designing scalable, high-performance, and cloud-native systems. My core expertise is in Node.js (Express, Hapi, NestJS, Fastify, GraphQL), where I build strong backend architectures using MongoDB (Atlas + Indexing), PostgreSQL, Redis, and real-time communication with WebSocket. I specialize in architecting distributed, event-driven systems with Kafka, RabbitMQ, AWS SQS, and gRPC, and I focus on delivering microservices that are resilient, efficient, and ready for production. Beyond coding, I have a strong foundation in AWS (S3, SES, SNS, SQS, CloudFront, Secret Manager) and third-party integrations like SendGrid for transactional messaging. I actively work on enhancing a unified notification API across multiple channels (Email, SMS, Push, Chat, In-App). I'm passionate about clean architecture, event-driven design, and solving real-world backend challenges, always striving to bring reliability, scalability, and innovation into every project I take on.
