Piyush Kumar — Senior Software Engineer

💻 About Me I'm a Senior Software Engineer with more than 5 years of experience architecting distributed systems that handle real-world scale — and more recently, building Agentic AI workflows that automate what used to take entire teams.At Nokia, I design cloud-native microservices, lead system architecture decisions, and integrate LLM-driven automation into enterprise network planning. Before that, I built real-time event pipelines at Ciena and shipped production applications at TCS.I care deeply about clean architecture, system reliability, and making AI do real work — not just demos.🧠 Core Expertise→ Backend & Systems: Java 17, Spring Boot, Spring Security, Hibernate, Kafka, REST APIs, Microservices, Distributed Systems → AI & Automation: LangChain, LangGraph, PydanticAI, RAG, LLM Orchestration → Cloud & DevOps: AWS, GCP, Docker, Kubernetes, Jenkins, CI/CD → Databases: PostgreSQL, MongoDB, MySQL, Redis → Frontend: React.js, JavaScript, Node.js → Design: System Design (HLD/LLD), Design Patterns, Event-Driven Architecture⚡ What I've Shipped→ Integrated an AI-powered network design assistant using LangChain + LLMs — automated ~40% of manual planning tasks and accelerated delivery cycles. → Architected microservices-based enterprise solutions deployed on GCP Kubernetes, handling real-time telecom workloads. → Built secure authentication systems with JWT/RSA, RBAC, and Spring Security — deployed with Docker & K8s. → Developed React.js dashboards for live monitoring and operations management across distributed systems.🎓 Certified: AWS Certified Cloud Practitioner✨ I'm driven by hard problems — complex system design, performance optimization, and figuring out how to make LLMs reliable in production. Always open to conversations about distributed systems, Agentic AI, or anything that pushes the boundary of what software can do.📩 Let's connect — I'm always up for collaborating on scalable, intelligent systems.
