What I'm looking for

I’m looking to lead end-to-end ML/LLM initiatives—building reliable evaluation, RLHF and NLP systems, and production data pipelines—while partnering with stakeholders to deliver measurable business impact.

I’m an astute Data Scientist with 6+ years of professional experience, specializing in developing and deploying data-driven solutions. I focus on advanced machine learning, deep learning, and statistical modelling to solve business challenges, improve operational efficiency, and strengthen decision-making with tailored insights.

Most recently as a Data Scientist - Team Lead, I directed a team of 10 data scientists to fine-tune large language models using Reinforcement Learning from Human Feedback (RLHF), delivered weekly high-quality benchmarks and datasets, and engineered an end-to-end RLHF tool for automated content generation, response ranking, and feedback aggregation. I’ve also built recommender systems that increased client revenue by 60%+, constructed knowledge graphs with Neo4j and OpenSearch vector search, and delivered document parsing, information retrieval, and transformer-based text-to-service matching—while accelerating pipelines through AWS SageMaker automation and robust QA and evaluation metrics.
