Tech Lead

Dec 2024 – Present · 1 yr 6 mos · Bengaluru

As a Tech Lead at Walmart, I am driving the design and development of ATOM AI – Walmart’s next-gen document understanding platform that automates complex document workflows using AI-powered processing and agentic capabilities.
ATOM AI is designed to intelligently ingest, extract, validate, and enrich structured and unstructured data from documents such as PDFs, invoices, order book and forms—at scale—powering downstream systems in supply chain, compliance and customer experience.
Key Responsibilities & Achievements:
Spearheaded the architecture and development of ATOM AI, a platform leveraging OCR, AI/ML models and custom agents for intelligent document extraction and classification.
Integrated PDF parsing, table extraction and semantic understanding layers to enable contextual inking and high-accuracy data structuring from noisy documents.
Built intelligent agents that learn from feedback and automatically adapt workflows, reducing manual intervention and enabling closed-loop automation.
Delivered scalable microservices using Java, Spring Boot, Kafka, and cosmosDB, deployed via Kubernetes and supported with React-based dashboards for visual traceability.
Led a team of engineers, conducting regular code and architecture reviews, mentoring juniors and instilling best practices in clean code, testing and observability.
Collaborated with data science teams to integrate custom ML models, improving extraction accuracy by over 30% for complex multi-page document sets.
Established robust CI/CD pipelines and contributed to Walmart’s internal AI tooling ecosystem for document processing.
