👨💻 Madhankumar Anandan | Senior Software Engineer & Delivery Lead
Welcome to my GitHub profile!
I am a Senior Software Engineer and Delivery Lead with 10+ years of experience designing and deploying scalable microservices and cloud-native platforms across logistics, e-commerce, and enterprise domains. I led multiple modernization programs on Java, Spring Boot, and cloud stacks, cutting API latency by 40%, increasing throughput by 3.3x, and improving release frequency from monthly to bi-weekly through CI/CD, while acting as a technical authority for complex migrations and system upgrades. Recent work focuses on Generative AI, including Prompt Engineering, RAG, and AI Agents, integrating LLMs into production systems to automate workflows and enhance developer and business productivity.
