About

Lead Backend Engineer with 8+ years building large-scale distributed systems, data platforms, and AI-native architectures. At Observe.AI, I've led platform engineering initiatives that process 10M+ events daily, architected systems handling 2B+ interactions, and delivered multimillion-dollar infrastructure optimizations. My expertise lies in zero-to-one execution and scaling critical infrastructure. I've re-architected storage layers that reduced costs by 30% and MongoDB footprint by 95%, designed ML-driven autoscaling solutions saving $800K+ annually, and built agentic multimodal platforms that balance cost, latency, and quality at enterprise scale. I specialize in transforming complex technical challenges into reliable, high-performance systems that directly impact business outcomes.I'm passionate about the intersection of backend engineering and data platforms—designing ETL pipelines, optimizing Snowflake workloads, building reconciliation frameworks for distributed systems, and creating unified ingestion patterns that enable teams to move faster with confidence. Whether it's scaling ElasticSearch 10×, building rule-driven detection engines, or separating service layers for reliability, I focus on solutions that are both elegant and pragmatic.Beyond shipping features, I drive engineering excellence through design reviews, architectural patterns, and mentorship - elevating teams while building systems that last.

Promoted

Feb 2023 – Present · 3 yrs 4 mos

Leading backend + data platform architecture for high-scale enterprise workflows (100M+ events/day).
Re-architected storage for 2B+ interactions, shifting from MongoDB to S3 + Snowflake + Kafka, reducing footprint 95% and cost 30%, with zero downtime migration.
Built a high-performance aggregation layer on Snowflake enabling low-latency, large-scale search and analytics workloads.
Designed a workflow-agnostic reconciliation engine introducing atomic claims, retries, distributed replay, and deep execution history → replaced blind DLQ recovery with automated, observable self-healing.
Architected ETL pipelines and data models powering high-performance analytics; standardized ingestion patterns across teams.
Introduced org-wide separation of external synchronous APIs vs internal async flows using Kong → improved reliability and latency consistency.
Led Agentic Multimodal QA platform: planning/execution agents over transcripts, KBs, and screen recordings with stratified sampling + stateful scheduling.
Org-wide Snowflake SME, driving compute/storage optimizations and ML-driven autoscaling → $800K+ annual savings.

Full Stack Developer

Jun 2018 – Dec 2020 · 2 yrs 6 mos · Bengaluru Area, India · On-site

As a Full Stack Developer at the Boeing India Engineering and Technology Center, I specialized in developing scalable and high-performance internal software solutions. My role was instrumental in an Application Modernization initiative, aimed at transitioning legacy software systems towards their next-generation counterparts. This involved migrating from intricate desktop applications to streamlined, Angular-based web applications, while concurrently overhauling the backend infrastructure to enhance scalability and maintain performance under high data volumes. I excelled in fostering collaboration among stakeholders, ensuring effective communication to derive optimized solutions for complex technical challenges.
Furthermore, I spearheaded the implementation of Continuous Integration/Continuous Deployment (CI/CD) pipelines, integrating SonarQube and Coverity to bolster code quality and security across various internal IT projects. My efforts were focused on enhancing operational efficiency, improving software reliability, and ensuring adherence to best practices in software development.
