Projects:
1. EDAMS Migration to AWS Greengrass V2
Led full-stack migration of legacy IoT control plane to Greengrass V2, enabling secure fleet management for 5K+ edge devices across 180+ AFT-X sites.
Reduced security incidents by 70% post-migration.
Critical architecture components:
Modular component deployment: Greengrass components (Java/Python) for hardware control, OTA updates, and certificate rotation.
Event-driven orchestration: API Gateway → EventBridge → Lambda (Java) for device command routing.
Zero-trust security: mTLS handshake via AWS ACM, with runtime attestation for edge devices.
2. Android Scanner Certificate Compliance System
Built a background daemon (Android/Volley) to enforce browser-attached ACM certificates for warehouse scanners.
Design
Periodic certificate checks via AWS ACM API (Velocity templates).
Atomic cert attachment to WebView instances, ensuring continuous TLS 1.2+ compliance.
3. FC Visualizer Service (NAWS)
Designed a state propagation engine to broadcast OEE/machine-personnel states to area managers, reducing operational latency by 40%.
Architected a real-time warehouse layout system for 500+ fulfilment centers (FCs), rendering equipment adjacency graphs via BFS-based cartesian plane placement (React-Flow, TS).
Deployed on AWS ECS with CloudFront caching, achieving <100ms P99 latency for global FCs.
Data pipeline: S3 (layout storage) → SQS (event-driven updates) → Lambda (state computation).

Oct 2020 – Feb 2022 · 1 yr 4 mos · Hyderabad, Telangana, India

Designed and deployed a scalable real-time and batch data service for Walmart, processing 5000+ Kafka topics with 100+ transformations, storing data in hourly-partitioned GCP buckets, ingesting into HDFS, and containerized using Docker on GCP Compute Engine with auto-scaling.
Created new service to consume Kafka streams, apply model-based transformations, and store processed data in hourly-partitioned GCP buckets.
Orchestrated Airflow DAGs to schedule Spark jobs, fetching hourly data from GCP and ingesting it into HDFS.
Used Apache Spark for distributed processing and applied auto-scaling on GCP to handle fluctuating workloads.
Containerized the service using Docker for portability and deployed it on GCP Compute Engine.
