Backend Engineer bridging scalable distributed systems with AI pipelines | Java | Spring Boot | Python | GCP

Hi, I'm Sakthivel Karthikeyan 👋 I am a Backend Software Engineer at Worldline, specializing in high-throughput microservices, distributed systems, and cloud-native architectures on GCP. I focus on bridging traditional backend engineering (Java 17, Spring Boot 3, WebFlux) with modern AI pipelines (Python, FastAPI, LLMs) to build smarter, scalable enterprise systems. I am proudly Dual Google Cloud Certified (PCA & ACE) and the Stall Winner at the 2026 Worldline TechForum. 📝 What I Write About: Core Backend: Java 17, Spring Boot 3, Reactive Programming, and Concurrency. Distributed Systems: Microservices architecture, fault tolerance (Resilience4j), and event-driven messaging. Cloud & DevOps: Cloud-native deployments, Docker, Kubernetes, and GCP optimizations. AI Integration: Building abstraction layers for LLMs and agentic backend pipelines. 🔗 Let's Connect: https://www.linkedin.com/in/sakthi6k/ sakthivelkarthikeyan2002@gmail.com
