Work Experience

Data Engineering Intern

Sigmoid Analytics

Jan 2026 - Present
  • Scaled analytics throughput to 10M+ daily records by architecting production Spark/Databricks/Snowflake pipelines, cutting downstream data-to-insight time by 25%.
  • Reduced pipeline failure rate by 35–45% across 15+ production workflows by implementing Airflow orchestration with end-to-end data observability and lineage tracking.
  • Cut ETL execution time by 30–40% and cloud compute costs by 22% by profiling Spark DAG bottlenecks and refactoring transformations.
  • Eliminated environment-related deployment failures by 50% by containerizing workloads with Docker and Kubernetes on Azure, standardizing CI/CD across all pipeline deployments.
  • Reduced dashboard query latency by 35% for analytics workloads by implementing data partitioning and caching strategies in Databricks.

Software Development Intern

AGRIX

Mar 2025 - Dec 2025
  • Achieved zero data loss across 50K+ telemetry events/day from 30+ IoT machines by owning end-to-end real-time ingestion pipeline design and deployment.
  • Eliminated 100% of duplicate billing incidents by engineering idempotent, event-driven microservices with exactly-once execution semantics and robust state-transition guards.
  • Delivered sub-300ms API latency on a role-based machine monitoring dashboard (FastAPI + React), improving operational visibility and stakeholder response time by 20%.
  • Improved GPS route reconstruction accuracy to ~90% by building a geospatial analytics pipeline using DBSCAN clustering and Concave Hull algorithms, enhancing billing precision.
  • Reduced critical production downtime by 30% by owning root-cause resolution and building structured debugging workflows.

Projects

Backend Operations Platform

FastAPIPostgreSQLRedisDistributed Systems
  • Scaled system throughput by 3.7x (120→450 req/s) under 1000+ concurrent users by engineering a concurrency-safe backend with exactly-once job execution and distributed lock management.
  • Reduced PostgreSQL lock contention by 61% and improved read latency by 59% via query optimization, connection pooling, and a Redis caching layer for high-frequency operations.
  • Cut mean job failure resolution from minutes to under 30 seconds by building real-time monitoring, alerting, and automated recovery mechanisms.

Agricultural Machine Monitoring Dashboard

FastAPIReact.jsMongoDBLeaflet.js
  • Enabled real-time visibility across 30+ machines by building a full-stack, role-based monitoring platform with live telemetry ingestion processing thousands of events/hour.
  • Achieved sub-300ms dashboard responsiveness and improved GPS billing accuracy via geospatial route playback, through query optimization and API-layer tuning.
  • Accelerated feature delivery by 20% by translating stakeholder requirements directly into backend contracts, reducing back-and-forth across teams.
