1. Built an automated MySQL partition lifecycle system for a 1.2B-row table (weekly RANGE) that archives cold data to S3-compatible storage in Parquet, enforces 18-week retention, plus a 6-week forward buffer for capacity planning, and adds health checks and alerts for safe, restartable operations.

2. Built and deployed a FastAPI job queue processing 10K+ jobs/day in MySQL with a systemd-worker pool; implemented database-level locking enabling concurrent, restart-safe processing with zero data loss and health monitoring and alerts.

3. Designed and deployed a multiprocessing, shard-based shipment optimization pipeline that parallelizes external API ingestion, uses cache-first persistence with restart-safe runs and metrics/alerts, and cut average shipment costs by ~50%.

4. Built an async, chunked MySQL-to-Polars pipeline processing 50M+ rows with SQLAlchemy async and Feather caching, reducing report generation time by 70% while maintaining rate-limited API ingestion.

1. Implemented independently a dual monitor mode for ESRI’s ArcGIS Enterprise Route Management - Route Planner application utilizing ESRI’s ArcGIS Maps SDK for JavaScript.

2. Enhanced the development of frontend components using React, implemented efficient logic using JavaScript and optimized state management through Redux.

3. Crafted a responsive & engaging UI for a vehicle routing application using HTML, CSS, & JavaScript, boosting user engagement.

4. Engineered data persistence mechanisms for user configurations, enhancing functionality across various monitor modes.

1. Data Management and System Optimization:

• Built a Node.js backend integrated with Rave; reduced query latency by 60% and improved throughput by 3x using strategic indexing, partitioning, and SQL query tuning.

• Developed responsive CRUD UIs for data capture/review; added access controls, input validation, and audit logs.

• Built Python ETL pipelines for batch and incremental loads with automated validation; instrumented services with observability via structured logs, metrics, and tracing.

• Implemented data retention/archival and backup/restore workflows to meet durability, auditability, and recovery requirements.

2. Achievements:

Received the ‘Star Performer’ award for the years 2016, 2017, and 2019. Awarded with 'Service and Commitment Award' and 'Certificate of Appreciation' awards in 2018.

3. TCS’s Ascent Leadership program:

Successfully completed TCS’s Ascent Leadership program, a corporate Leadership Development Program envisioned to coach and equip first-time managers across TCS to effectively deliver business results.
