About Me

SYSTEM BRIEF

Building autonomous AI systems that ship in production.

AI Engineer based in Bengaluru, Karnataka, currently building autonomous agent systems at Thrivv AI (Remote, Dubai). I specialize in LLM-powered agents, Retrieval-Augmented Generation (RAG), LLM fine-tuning, and production AI pipelines — from multimodal interview systems to financial copilots and document forensics engines.

CAREER LOG

Previously at Vacanzi as AI Engineer and at Rubixe AI Solution as a Data Scientist Consultant, I've delivered ML models, RAG chatbots, computer vision pipelines, and client analytics solutions. I work across LangChain, SmolAgent, PyTorch, FastAPI, Qdrant, Redis, PostgreSQL, and AWS — with a focus on shipping reliable, low-latency AI systems.

Agentic AI

LLM agents, RAG pipelines, and fine-tuned models built for real workloads.

Low Latency

Redis caching, vector search, and optimized inference for production speed.

Production Ready

Secure, scalable systems with clear engineering and business alignment.

WHY WORK WITH ME

I combine deep technical expertise in agentic AI and LLMs with clear communication — translating complex engineering into business outcomes. I invest time upfront to understand the problem, then build secure, scalable solutions that perform in production.
