Work Experience

Assistant System Engineer

Tata Consultancy Services

Jul 2022 - Present

Built the Open Interest (OI) monitoring microservice (HPTM), tracking client long/short positions across client, trading-member, and constituent levels — generating graduated breach alerts (60%/75%/90%/100%) against MCX-mandated position limits, with automated violation flagging and a revoke workflow to restore trading eligibility. Built and maintained the trade-message processing pipeline, transforming and routing FIXML and JSON messages across the end-to-end trade flow. Improved backend performance by optimizing IBM DB2 queries, stored procedures, and data access layers for high-volume trade data. Owned application deployment on OpenShift (Red Hat), using Quay-based image builds for consistent, repeatable production releases.

Onsite Experience

TCS @ MCX Client Site

Jan 2023 - Jan 2024

Led root cause analysis (RCA) for high-priority production incidents and drove real-time resolution, delivering permanent fixes to prevent recurrence. Partnered directly with client teams on release planning, business-critical validation, and production troubleshooting. Built monitoring scripts to track service status during market-open windows, cutting manual intervention. Monitored Kafka consumer lag via Control Centre during live market hours, maintaining zero message delay in trade flow. Managed production deployments and monitored application health for a live platform processing crore-worth of trades daily.
