Hello, I'm

Siddharth Kumar

Senior Software Engineer – Generative AI

Senior Software Engineer with 4+ years of experience specializing in Generative AI, LLM-powered agents, and distributed data platforms. I build intelligent workflows that enable users to securely interact with complex enterprise data using natural language, orchestrating systems through LangChain, RAGAS, Langfuse, and the Model Context Protocol (MCP).

Beyond AI architecture, my core engineering foundation is built on Python, AWS, Apache Spark, and robust ETL pipelines. I implement the rigorous end-to-end automation and validation testing required to reduce manual investigation and ensure these agents are highly reliable, scalable, and fully production-ready.

The Engineer

I am a versatile and result-driven professional specializing in Generative AI systems, LLM-powered agents, and distributed data platforms.

My philosophy is rooted in end-to-end ownership. Building an AI model is only half the battle; the real complexity lies in the orchestration: evaluating hallucinations, verifying agentic tool calls, validating data streams, and scaling the infrastructure. By bridging advanced software development with rigorous quality automation, I deliver intelligent systems that actually work reliably in production. Furthermore, I am continually architecting for the future—actively anticipating and integrating next-generation frontier models like Opus 4.6 and GPT 5.2 into my orchestration pipelines.
