SDE-2 @Leucine - AI for pharma | Turning Complex Problems into Scalable Solutions | Java • Spring Boot • Microservices • SQL • Kafka

About

Hi, I'm Falgun — a Backend Engineer with 3+ years of experience building scalable, reliable distributed systems in Java and Spring Boot. I currently work as an SDE-2 at Leucine, where I've designed and built production microservices from the ground up that power core platform capabilities used by leading pharmaceutical enterprises like Cipla and Amneal. My work spans event-driven architecture with Apache Kafka, centralized data architecture design, and performance engineering — from optimizing slow queries and indexing to profiling memory and resource usage under load. Previously at Salesken.ai, I architected telephony calling flows and CDR pipelines that reliably processed over 1M+ webhook events, optimized SQL queries to boost application performance by ~70%, and led an end-to-end database migration from ElasticSearch to PostgreSQL. I also owned production deployments, executing zero-downtime, high-availability releases with minimal customer impact. Beyond development, I handle the complete delivery lifecycle — containerizing applications with Docker, automating CI/CD pipelines with Jenkins, and supporting releases in production. I bring strong fundamentals in data structures, algorithms, and system design to every problem I work on. Based in Bengaluru, I thrive in collaborative environments where I can solve challenging problems, mentor peers, and continuously improve system performance while contributing to business-driven solutions.
