Ravi Pushkar
@ravipushkar
I build production LLM, RAG, agentic AI, and high-performance inference systems end-to-end.
What I'm looking for
I've shipped production LLM systems at Fujitsu, including a cross-lingual RAG Q&A platform serving five languages that improved answer F1 by approximately 32% over baseline.
I fine-tuned BGE-M3 embeddings, LLaMA 3.1 8B, and CodeT5 models; delivered a Flask REST API with P95 latency below 140 ms on ARM EC2; and automated ARM SVE512-to-SVE2 SIMD translation with 98.2% functional correctness.
At Test Sigma, I architect an autonomous LLM agent that crawls web applications, extracts semantic entities from product documentation and pull requests, and builds a Neo4j knowledge graph for CI regression-impact reporting.
My work also spans oneDNN and BLAS optimization, AWS infrastructure migration, scalable Python pipelines, and backend APIs. I hold a dual B.Tech and M.Tech in Mathematics & Computing from IIT Delhi and am open to relocation.
