Karthik’s strongest areas are LLM\-powered services and RAG pipelines, event\-driven distributed systems, cloud infrastructure, ML integration, and resilient microservices architecture\. His technical work includes LangChain, GPT\-4, Pinecone, Amazon Bedrock, Kafka, Kubernetes, FastAPI, AWS, Docker, PyTorch, and scikit\-learn\. At Amazon, Karthik led a JDK migration across 12 distributed services, reduced API response latency by 60% through query optimization, and integrated ML\-based anomaly detection that reduced false\-positive alerts by 40%\. At Salesforce, he built Python backend services processing more than 500 support cases daily and ETL pipelines that removed more than 15 hours of weekly manual work for an eight\-engineer team\. More recently, Karthik built a production RAG system with sub\-200ms semantic search across more than 2 million document embeddings and a real\-time observability platform processing more than 10,000 events per second with 92% anomaly\-detection precision\. ## Services - PostgreSQL - Classifiers - Salesforce\.com Administration - AWS SageMaker - Zero\-based Budgeting - Chai\.js - Set\-up Reduction - AIOps - Operating Systems - Graphs - Open API - Semantic Search - Sensu Observability Pipeline - Client Accounts - Complexity Reduction - AWS Cloud Migration - Amazon Kindle - Code Refactoring - JavaScript - Large Language Models \(LLM\) - TickIT - Scalable Architecture - Real\-time Data - TensorFlow - Amazon CloudWatch - Data Reporting - Startups - Data Classification - MLOps - AWS Lambda ## Highlights - Led a JDK migration across 12 distributed services at Amazon\. - Reduced API response latency by 60% through query optimization at Amazon\. - Integrated ML\-based anomaly detection at Amazon, reducing false\-positive alerts by 40%\. - Built Python backend services at Salesforce that processed more than 500 support cases daily\. - Developed Salesforce ETL pipelines that eliminated more than 15 hours per week of manual work for an eight\-engineer team\. - Engineered a production RAG system with sub\-200ms semantic search across more than 2 million document embeddings\. - Built a real\-time observability platform processing more than 10,000 events per second with 92% anomaly\-detection precision\. - Shipped an AI food\-ordering platform from zero to one in nine months\. - Built the AI food\-ordering platform using a five\-stage LangGraph architecture\. - Contributed end to end on the AI platform, from architecture through deployment\. - Designed fault\-tolerant systems with retry mechanisms, pod failover, and guardrails to prevent system failures\. - Proposed and implemented a microservices architecture change to improve system resilience\. - Won stakeholder buy\-in for a mid\-project architecture change through a data\-driven pitch deck using P55 and P95 performance metrics\. - Integrated Meta API, Stripe, and PayPal into systems\. - Prioritized end\-user experience in architectural decisions\. ## FAQ ### What does Karthik do?
