WORK HISTORY
Senior Software Development Engineer @Oracle
Santa Clara, CA, US
Architected and shipped an end-to-end LLM natural-language-to-SQL platform on OCI — users query enterprise databases in plain English, with row-level governance, retrieval-augmented context, and SQL guardrails preventing unsafe operations.• Led backend redesign of a core API service, cutting p95 latency and halving infra cost per request by introducing async processing, smarter caching, and query-plan rewrites.• Drove zero-downtime migration of a multi-region data platform to a new service mesh, coordinating across 3+ teams and completing the cutover without a single customer-visible incident.• Mentored 2 junior engineers through design reviews and on-call ramp-up; both are now independent owners of production services.

ABOUT HANSRAJ PABBATI
Most companies have millions of rows of data no one can query. I build the AI systems that change that-I\'m an AI Software Engineer at Oracle, focused on taking LLM systems from \"cool demo\" to \"production workload enterprises actually trust.\"My current work: designing and shipping an end-to-end natural-language-to-SQL platform — users ask questions of enterprise databases in plain English and get secure, governed answers back, with retrieval-augmented context, row-level access control, and SQL guardrails that prevent unsafe operations.Before Oracle, I spent nearly 4 years at AWS building API and data platforms that served customers and processed millions of records across regions-What I actually do (and like doing):→ LLM application engineering: RAG pipelines, prompt systems, function calling, structured outputs, agent loops→ Retrieval + vector search: embeddings, hybrid search, re-ranking, chunking strategies that don\'t hallucinate→ Evals + guardrails: offline evals, regression tests for prompts, output validation, safety filters→ Production plumbing: the backend APIs, caching, observability, and cost controls that keep AI features alive at scale→ Python first, Java when the system demands it, across AWS, OCI, and GCP-Background: 8+ years in software engineering, the last few focused on the intersection of GenAI and production systems. MS in Computer Engineering from San José State University. Based in San Jose, CA- Open to connect if you\'re- Building AI Engineer / ML Engineer / Applied AI teams — happy to chat about roles where LLM systems go to production- A fellow engineer working on RAG, agents, NL-to-SQL, or evals — I love comparing notes on what\'s actually working- Building something and want a technical collaborator or advisor.DM me here or reach me at h••••••••@gmail.com — I read every message.
