Senior Software Engineer at Walmart Global Tech India

About

Senior Data Engineer with 7+ years of experience building and owning large-scale, production-grade data platforms on GCP. I specialize in designing Spark-based batch and incremental pipelines, Airflow orchestration, and cloud-native data solutions using BigQuery, GCS, and Dataproc. My work focuses on solving complex supply chain and optimization problems through scalable, reliable, and cost-efficient data systems. At Walmart Global Tech, I have led the re-engineering of legacy supply chain platforms, scaling systems from 1 vendor to 100K+ vendors and 150K+ distribution centers, while significantly improving performance, reliability, and cost efficiency. I have a strong track record of: • Driving large-scale cost optimizations (66%+ reduction, $9M+ savings annually) • Building highly reliable pipelines with SLA monitoring and observability frameworks • Designing multi-tenant, config-driven architectures for scalable deployments • Leading end-to-end ownership — from design to production debugging and optimization • Developing AI-driven solutions for automated performance tuning and cost diagnostics I enjoy solving hard data problems at scale and building systems that directly impact business decisions, efficiency, and cost.

Senior Software Engineer at Walmart Global Tech India, Aug 2026 - Present · 3 mos, Bangalore Urban, Karnataka, India

Software Engineer 3 at Walmart Global Tech India, May 2022 - Jul 2026 · 4 yrs 3 mos, Bengaluru, Karnataka, India, Worked on SmartGrid, an optimization-driven supply chain platform enabling batch, on-demand, and near real-time decision-making for inventory planning and flow. Built and supported Inbound Order Optimization (IO2) solutions that generate truck-level inventory distribution from vendors to DCs under multiple operational constraints. Key Contributions & Impact: • Owned End-to-end ownership of large-scale data pipelines (batch and incremental) • Spark performance tuning and cost optimization (66% cost reduction, $9M+ savings) • Airflow orchestration, SLA monitoring, and production reliability • Low-level system design covering failure scenarios and backfills • Production incident debugging and root-cause analysis • Mentoring Junior Engineers and driving high-quality delivery • Engineered multi-tenant architecture using a single codebase, DAG, and deployment model to scale across vendors/business units • Built a config-driven contingency framework enabling N-day fallback data availability to ensure uninterrupted downstream planning • AI-Driven Spark Performance Agent: Built an AI-powered agent that autonomously diagnoses Spark inefficiencies (skew, spill, shuffle overhead, resource misconfig) across event logs and generates prioritised remediation plans. • Cost Optimisation via AI Agent: Reduced Spark job execution costs by $300 through AI agent-driven detection of over-provisioning, excessive partitioning, and runtime bottlenecks.

Senior Software Engineer at Wipro, Dec 2020 - Apr 2022 · 1 yr 5 mos, Bangalore Urban, Karnataka, India, I was an integral part of Wipro's patented offering "Smart test ride", an Industry's first initiative where test-ride vehicles act as virtual salespersons and "speaks for itself" and converse with the vehicle buyer contextually, during a test ride. This product redefines the experience of the test-ride through a speaking bike, which conversationally engages and guides the buyer to evaluate the bike in the best possible way, and advises the actions to optimally use the bike. I was part of the engagement with KTM Austria's Innovation unit, where it partnered with Wipro to co-innovate and launch this in Germany, Austria and India. Key Responsibility included – • Alexa Voice Skill architecture design and end to end development of the Alexa Skill • Working on the best smart devices available for the test ride for voice interaction • Developed "conversation nets" for natural, personality-driven conversations based on situations • Setting up the voice skill testing on a mass scale • Automation Testing of the Alexa Skill • Conduct workshops in Wipro to promote voice-based solutions for the project I developed the smart voice assistant technology with Google Actions for client cars in English and Japanese locales. This concept allowed car drivers to assist them while driving (say open sunroof, turn on ac, ambient lights on, etc.)

Software Engineer at Wipro, Jun 2018 - Nov 2020 · 2 yrs 6 mos, Bangalore Urban, Karnataka, India, I worked in Wipro’s Connected vehicles platform where we develop the innovative product, which elevates the ownership experience of vehicles through 20+ features with Alexa Skill, Google Action, AWS Lex Chatbot, mobile, web application and smart Dongle. My role involved deeply to provide the best Voice User Experience to the user. Key Responsibility included – • Voice Skill architecture design, and add patterns to the voice skill, and chatbot application. • End to end development of the Alexa Skill, Google Action and AWS Lex Chatbot • Certification and Publication of the Alexa Voice Skill • UI, backend development, and creating REST APIs I developed the smart voice assistant technology with Alexa/Google for clients - Indonesia and Japan. This concept allowed car drivers at home to converse with the car (say check fuel levels, door open status, lights on etc.) and issue commands (close door through voice, set a virtual anti-theft curfew)
