About Karthik S

I’m a Software Engineer with 7+ years of experience building large-scale distributed systems across Big Tech, mid-sized companies, and startups. I enjoy working on complex engineering problems and turning ambiguous ideas into reliable, production-ready systems with a growing focus on production ready AI agentic systems.Earlier in my career, I worked at Amazon, where I developed a strong mindset around customer obsession, ownership, and long-term impact—principles I continue to apply in every product and platform I build.In recent years, my work has increasingly focused on Agentic AI and applied ML systems. I’ve been building LLM-powered workflows using LangChain and LangGraph, designing RAG pipelines with vector databases, and developing ML and analytics workflows on Snowflake and Spark. I enjoy the intersection of backend engineering, data platforms, and AI—especially when systems need to scale and evolve over time.My current work sits at intersection of deep backend expertise with data combined with hands on expertise in building AI systems beyond simple LLM integrations. I design agents that reason, plan, and act autonomously — with proper tool orchestration, memory management, observability, and failure recovery built in from the start.What I work with:Languages: Java, Python, TypeScript, Scala, Go, C++, RubyAgentic AI & ML: LangChain, LangGraph, RAG pipelines, vector databases, ML workflow design, evaluation and observabilityCloud & Architecture: AWS (Lambda, Step Functions, EventBridge, SQS/SNS, Kinesis, Firehose), serverless and event-driven systems, AWS CDKDatabases & Analytics: PostgreSQL, Aurora, DynamoDB, Elasticsearch, MongoDB, S3 + Athena, Redshift, SnowflakeData Engineering: Spark, EMR, Airflow, AWS Glue, batch and streaming data pipelinesI’m always excited to take on challenges in backend, data, cloud, and agentic AI systems, especially where thoughtful design and real customer impact matter.
