What I'm looking for

I’m looking for a role where I can build and deploy AI/ML products end-to-end—RAG, LLM fine-tuning, and MLOps on AWS—while improving latency, reliability, and evaluation quality with real production feedback.

I’m an AI/ML engineer who turns LLM ideas into production systems—RAG pipelines, LLM fine-tuning, and reliable inference. I specialize in model evaluation and practical retrieval design to deliver accurate, fast answers.

In my current Business Analyst role, I automate workflows and apply GPT-based document intelligence to reduce manual processing while improving accuracy. As an AI/ML Freelance Engineer, I built a voice-enabled financial assistant using RAG (500+ earnings reports) and a Gmail–Slack assistant with multi-modal processing (Whisper, Google TTS), handling 200+ queries/day.

I also ship end-to-end projects like DeciScope and RepoMind, combining hybrid retrieval (Pinecone + PostgreSQL/pgvector) with AWS serverless infrastructure to cut latency and track production metrics. Recently, I fine-tuned Llama-3.2-3B with QLoRA and deployed optimized inference with vLLM, improving ROUGE-L and BERTScore while reducing VRAM needs.

Fine-tuned Llama-3.2-3B on 8.5K+ code documentation examples using QLoRA (rank=32, alpha=64), reducing VRAM from 24GB to 8GB. Improved ROUGE-L (0.42→0.56) and BERTScore (0.71→0.91) versus the base model, and deployed with vLLM for sub-1.2s generation at 512 tokens, publishing the model on HuggingFace with documentation.
