Work History
Senior Software Engineer
NEC Software Solutions Pvt
04.2023 - Current
- Senior contributor to Crystal‑Ball, a modular internal data platform adopted across Gupshup teams (analytics, bots, event-driven systems). Contributed to:
Event ingestion via Apache Hudi for batch and Spring Boot APIs for real-time (Kafka-backed) flows
Processing abstraction with an annotation-based SDK (Java Reflection + string templates) to auto-generate Flink pipelines
Serving layer powered by Postgres and a SQL-to-API utility for analytics access
Deployment automation using Helm and GitLab CI/CD
— resulted in a 60% reduction in end-to-end pipeline rollout time for consuming teams - Migrated analytics and billing pipelines (up to 7 TB/day) from AWS Redshift to Apache Flink on Amazon EKS, cutting AWS spend by $70K/month
- Developed real-time Flink streaming pipelines (9K–10K events/sec) using the Crystal‑Ball SDK to power dashboards and surface latency issues
- Built an asynchronous report generation system using Spring Boot REST APIs, RabbitMQ, Java consumers, and presigned S3 URLs for secure access
- Co‑designed an Apache Hudi (T+30) pipeline for WhatsApp, SMS, and RCS events—achieved 99.95% accuracy against Meta billing data
- Created Octopus, a Markov model-based load generation tool for simulating event flows with configurable TPS and state transitions
- Led performance tuning and load testing of Flink jobs on Kubernetes provisioners for large-scale data pipelines
- Established end-to-end monitoring using Prometheus, Grafana, and automated alerting for all streaming applications
SOFTWARE ENGINEER
ORACLE CERNER
06.2019 - 04.2023
- Developed a data delivery agent for the CMLE platform, enabling reliable event propagation and reducing end‑to‑end latency.
- Built stateful streaming utilities—including materialized views and historical data bootstrapping—in Apache Flink, enhancing pipeline robustness.
- Migrated key applications (Sepsis rules, Rapid Response, VTE) to streaming platforms, improving processing efficiency and saving $7 K/year in infrastructure costs.
- Implemented a production data pipeline for ML model insights, publishing results to AWS SNS for journaling, monitoring, and downstream services.
- Evaluated Apache Flink, Apache Spark, and IBM Streams for Cerner use cases; delivered a real‑time auto‑charting POC for patient vitals and conducted performance & scale testing on AWS EMR and AWS KDA.
- Architected the CareAware Quality dashboard, designing RESTful APIs to aggregate data from Jira, Jenkins, GitHub, Fortify, and other tools—improving executive visibility into product quality and team performance.
