I build production\-grade applications using Java, Python, Spring Boot, FastAPI, Apache Kafka, AWS, Apache Spark, PostgreSQL, and event\-driven microservices\. At Capital One, I have worked across customer onboarding, distributed backend services, data pipelines, API performance, and database reliability\. I designed and built a Backend\-for\-Frontend service that reduced customer onboarding time from more than two days to under one hour, while eliminating a 48\-hour manual escalation process through automated validation and workflow orchestration\. Previously, I helped build a self\-serve advertising platform supporting 15,000\+ US car dealerships\. I developed Spring Boot and Kafka\-based services to process and publish thousands of vehicle records daily, implemented retry and recovery mechanisms, optimized API latency to 100 ms or less, and improved Aurora PostgreSQL failover times by more than 90% through HikariCP and connection\-management tuning\. My work also includes building AWS Glue and Apache Spark ETL pipelines, deploying applications on ECS Fargate, designing REST APIs and microservices, working with React and micro\-frontends, and integrating OpenAI APIs into production applications\. I built an AI\-assisted investment research platform for a Singapore\-based hedge fund using FastAPI, RDS PostgreSQL, React, ECS Fargate, and document\-analysis workflows\. Core skills: Backend Engineering, Platform Engineering, Distributed Systems, System Design, Java, Python, Spring Boot, FastAPI, Apache Kafka, AWS, AWS Glue, Apache Spark, PostgreSQL, Aurora PostgreSQL, REST APIs, Microservices, Event\-Driven Architecture, ETL Pipelines, API Performance Optimization, Database Reliability, Observability, New Relic, Splunk, JMeter, React, OpenAI APIs, PyTorch, and TensorFlow\. I’m particularly interested in solving complex backend and platform engineering problems involving scale, reliability, performance, data processing, and developer productivity\. ## Location Bengaluru ## AI stack claude code gemini langgraph openai windsurf ## Work experience Senior Associate \(SDE 2\) at Capital One, Jan 2026 \- Present · 8 mos, Slashed customer onboarding time from 2\+ days to under an hour by architecting a purpose\-built Backend\-for\- Frontend \(BFF\) from scratch, establishing a highly scalable micro\-frontend \(MFE\) integration pattern\. • Implemented automated validation and onboarding workflows that eliminated a 48\-hour manual escalation process, enabling customers to onboard immediately following sales engagement\. • Engineered automated ETL workflows via AWS Glue\(Apache Spark based runtime\), optimizing data processing efficiency for Google Ads marketing campaigns improving the reliability of downstream marketing data used in performance decision\-making • Drove adoption of AI\-assisted software development practices across multiple engineering teams through workshops, onboarding sessions, and reusable engineering patterns, increasing developer productivity and accelerating feature delivery\.
