Banglore

Promoted to Associate Technical Architect, leading the design and delivery of scalable, cloud-native platforms across Java, Spring Boot, React, PostgreSQL, and AWS/Azure. I drive architectural decisions, engineering standards, and platform modernization while mentoring engineers and collaborating across engineering, product, and data teams to solve complex business problems at scale. A recent flagship initiative was an AI-powered healthcare rules engine that ingests USA healthcare policy PDFs and automatically extracts business rules and their source citations, surfacing them in an interactive UI for review: - Architected an agent-based extraction pipeline using the Spring AI framework and the Anthropic API, orchestrating LLM agents to parse complex, unstructured policy documents and return structured rules with traceable citations. - Built the backend in Java + Spring Boot with REST APIs for document ingestion, agent orchestration, and rule retrieval, plus a React + TypeScript front end that displays extracted rules alongside their original citations for easy verification. - Automated rule extraction that was previously manual, improving accuracy and turnaround on healthcare compliance workflows. Beyond this, I lead AI-powered automation initiatives and platform modernization efforts, focused on building highly reliable, performant, and maintainable systems. I care about building systems that don't just work, but work elegantly, at scale, and without excuses.

As a Senior Software Engineer, I design and build large-scale, high-performance systems that power data-intensive products. My work spans backend engineering, distributed architectures, system design, and end-to-end platform optimization. I specialize in Java, Spring Boot, PostgreSQL, React, and cloud-native deployments on Kubernetes—delivering solutions that stay fast, stable, and scalable even under extreme workloads. I lead development of complex analytics pipelines, multi-tenant architectures, and secure data-processing systems used across enterprise environments. My responsibilities include designing database schemas for massive datasets, optimizing query performance, orchestrating microservices, and enforcing high standards of observability, reliability, and automation. I also champion code quality, performance engineering, and architectural modernization. My role is a mix of engineering execution and strategic problem-solving: breaking down messy problems, eliminating bottlenecks, improving developer experience, and moving platforms toward a cleaner, more scalable future. I care about building systems that don’t just work—but work elegantly, at scale, and without excuses.

Bangalore Urban, Karnataka, India

In my current role as a Software Engineer, I specialize in crafting scalable APIs using Java and Spring. My commitment to efficiency and productivity has driven me to develop multiple Python and Shell scripts, resulting in a remarkable 40% increase in productivity across various tasks. One significant achievement I'm proud of is addressing a performance issue with a batch job that previously took over 40 hours to complete. Through meticulous analysis and optimization, my team and I successfully reduced its execution time to under 1 hour, significantly enhancing overall system efficiency. My current project presents a unique challenge, as it caters to more than a million users and deals with intricate time series data. To meet these demands, I work with a diverse tech stack, including Java, Spring, Redis, MongoDB, Kafka, and MySQL, allowing me to architect solutions that scale seamlessly. I also like to contribute to my Front-end team for some small tasks in React and Typescript.
