About Piyush Kumar Sahu

I\'m a backend engineer with a strong foundation in cloud-native, event-driven architectures and a growing focus on applied AI/LLM engineering.On the backend side, I\'ve designed and built microservices-based platforms handling real-world workflows — from event-driven processing with Kafka and serverless compute, to NoSQL storage, REST APIs, and end-to-end service ownership. I\'ve built production services from scratch, including a fully integrated email notification system wired into a distributed event pipeline.More recently, I\'ve been working at the intersection of AI and engineering — helping build a RAG-based code reviewer from the ground up, which pushed me to develop applied LLM engineering skills hands-on. It\'s an area I\'m actively deepening.In my current role, I work heavily on Infrastructure as Code — designing and maintaining enterprise-grade Terraform modules for cloud services at scale, managing multiple codebases, and automating workflows to improve developer productivity. I hold the HashiCorp Terraform Associate certification (2026) and work extensively across AWS, GCP, Azure, and IBM Cloud.Core areas:• Backend Engineering — Python, Node.js, Go, Express.js, REST APIs, microservices• Event-Driven Architecture — Kafka (Confluent), AWS Lambda, serverless• Applied AI / LLM Engineering — RAG, LLM integration• Cloud Platforms — AWS, GCP, Azure, IBM Cloud• IaC & DevOps — Terraform, Packer, Docker, KubernetesAlways open to conversations around backend systems, AI engineering, and cloud-native architecture.
