What I'm looking for

I’m looking for an AI/ML role where I can build reliable Adaptive RAG + agentic systems, ship production ML services with FastAPI, and improve performance using MLOps tooling—while working with teams that value measurable impact and clean engineering.

I’m an AI/ML Engineer undergraduate focused on Machine Learning, Generative AI, and NLP. I build Adaptive RAG pipelines and agentic AI architectures that connect directly to Claude/OpenAI APIs, and I care deeply about making LLM systems reliable in production.

In internships, I developed end-to-end ML inference pipelines with FastAPI, engineered regression and classification workflows to production-readiness, and optimized LLM infrastructure by migrating from GPT-based models to self-hosted Ollama to reduce API costs and improve data privacy. I also built an automated ethical code analysis system that clones repositories and evaluates source code across 11 ethics pillars with evidence-backed, actionable fix suggestions.

Across projects, I’ve shipped scalable solutions: an MLOps pipeline for hotel reservation cancellation prediction with CI/CD via Jenkins and deployment to Google Cloud Run, BERT-based sarcasm detection using reproducible training workflows, and YouTube comment sentiment analysis deployed on AWS with monitoring via MLflow and versioning with DVC. I’m passionate about building systems that can learn from feedback, route knowledge intelligently, and deliver measurable performance.
