Hitesh Sharma
About
I am Hitesh Sharma, a Staff Software Engineer and AI Platform Architect based in Mumbai. I build intelligent systems, distributed platforms, search infrastructure, and the developer tooling that helps teams operate them reliably.
This site is where I write down the useful parts: architecture decisions, production failures, experiments, and lessons that remain relevant after the framework or model changes.
What I write about
- AI systems: agents, evaluation, inference, and production reliability.
- Retrieval and search: RAG, semantic retrieval, relevance, and vector systems.
- Distributed platforms: events, APIs, cloud systems, and platform architecture.
- Engineering practice: developer experience, technical leadership, and operating software.
I bring more than eight years of engineering experience to these notes, including search ingestion operating near 5M events per day and fine-tuning a 3B-parameter model for structured extraction from research documents.
