Nilesh Sharma

I’m a Senior Backend / Founding Engineer with 6+ years of experience building and scaling B2B SaaS platforms from 0 to production. I specialize in architecting event-driven systems, distributed platforms, and data-intensive pipelines—delivering reliability, performance, and measurable cost reductions.

At Josys, I architected an event emitter framework using Sidekiq and AWS SNS to handle 2M+ messages per day, migrated critical pipelines to Kafka for real-time workflows, and re-architected Spark (Scala) pipelines to cut infrastructure costs by 60%. I also build resilient orchestration with Apache Airflow and Temporal, optimize ingestion scalability (20K+ records/upload, 80% less memory), accelerate deployments (15 mins to 5 mins), and lead engineering decisions through mentorship and product ownership.
