Pahuldeep Singh
I build reliable distributed systems, cloud-native platforms, and applied AI products across backend, infrastructure, and UI.
Engineering focus
Systems that are resilient, observable, secure, and maintainable after launch.
About Me
I am a Senior Full-Stack Engineer specializing in distributed systems, cloud-native architectures, and applied AI. I architect microservices, high-performance APIs, and event-driven platforms designed to operate reliably at scale.
At Calian Advanced Technologies, I design and deliver production-grade systems across Go, TypeScript, Node.js, Ruby on Rails, Python (Flask, FastAPI, Django), React, and Vue.js — underpinned by AWS, Kubernetes, Terraform, Kafka, and modern observability tooling. My work spans the full stack from infrastructure to UI, with a strong emphasis on resilience, security, and operational excellence.
Previously at Valley Fiber, I built React and Vue.js frontends, backend services in Node.js and Python, engineered ETL pipelines, and drove database performance optimization to support scalable data processing infrastructure.
I hold AWS Solutions Architect Associate and CCNA certifications, and bring deep hands-on experience across DevOps, CI/CD, testing strategy, and Agile delivery. I am driven by building intelligent, maintainable systems that solve complex real-world engineering challenges.
