Principal Data Engineer – Lowe’s Companies, Inc.
Arnab Kundu
I build resilient data platforms, workflow automation systems, and cloud-native engineering foundations for teams that need scale, observability, and speed without losing operational control.

Data engineering with a full-stack engineer’s sense for systems.
I am a Principal Data Engineer at Lowe’s in Charlotte, focused on modern data platforms, workflow orchestration, cloud-native delivery, and engineering reliability. My work sits at the intersection of data, infrastructure, automation, and product-minded engineering.
At Lowe’s, I have worked on Apache Airflow on Kubernetes, high-throughput data pipelines, GitOps-driven deployment flows, observability, RBAC, and integrations that make enterprise workflows easier to operate at scale.
Before Lowe’s, I built systems across gaming, publishing, and mobile engagement platforms, including real-time leaderboards, fraud-detection signals, large-scale platform migration, and stream-processing services.
Principal Data Engineer
I build and scale enterprise data orchestration and platform capabilities, including Airflow on Kubernetes, CI/CD workflows, observability, secrets management, OIDC/RBAC, and cross-team adoption patterns for workflow automation.
- I scaled Airflow environments for 30K+ tasks per day across multiple environments.
- I integrated monitoring and logging with Prometheus, Grafana, and ELK-style observability.
- I have worked across ETL, BI pipelines, IoT-edge communication, RUM tooling, and DevOps modernization.
Senior Software Engineer
I designed low-latency, high-ingestion systems including leaderboards, database change-log ETL, monitoring, anomaly detection, fraud signals, and prize-computation services.
Senior Software Engineer
I helped modernize a large publishing platform through PWA work, infrastructure improvements, monitoring, modularization, and performance optimization for major publishing traffic.
Software Developer
I worked across full-stack dashboards, stream processing, cross-platform engagement systems, and real-time smart-trigger services in a fast-moving marketing technology environment.
Workflow Orchestration
Airflow on Kubernetes
I focus on production-grade orchestration with Kubernetes executors, Helm deployment patterns, DAG promotion, secrets management, monitoring, logging, and access controls.
Real-Time Scale
Leaderboards and Event Streams
I have built high-ingestion systems tuned for variance, low latency, rollback safety, and resilient downstream analytics.
Platform Migration
Publishing Infrastructure
I have worked on application modernization and performance optimization where latency, page speed, and operational stability mattered every day.
Engagement Platforms
Lifecycle Automation
I have delivered cross-platform notification and engagement systems backed by streaming pipelines, adaptive user lifecycle logic, and full-stack product delivery.
Comfortable from pipeline internals to platform operations.
Built on curiosity, community, and range.
I studied Computer Science at SRM University in Chennai and participated in technical and cultural campus programs including Aarush, SRMMUN, and Milan.
I have also volunteered with CRY and worked early in my career on SRM Search Engine, a NIXI-funded project that combined big-data development and web engineering.
