Description

Hi, I’m Joydeep. I am a Senior Machine Learning Engineer and Data Scientist with over 10 years of professional experience building and deploying production-grade AI systems at tech companies like Google, Amazon, Flipkart and IBM Research.

I help businesses bridge the gap between complex engineering realities and high-impact business products, specifically focusing on Generative AI pipelines and Large Language Models (LLMs).

What I bring to your project:

• GenAI & LLMs: End-to-end implementation of pre-trained and fine-tuned Large Language Models optimized for domain-specific context (such as E-commerce, HR, and Operations).

• Advanced NLP & Analytics: Deep expertise in semantic similarity, entity extraction, knowledge graph construction from unstructured data, and automated pipeline design.

• Causal Inference: Building data pipelines using advanced statistical frameworks (like Double Machine Learning) to measure the incremental business impact and customer acquisition value of your programs.

• Full-Stack AI Architecture: Designing the system architecture, code implementation, and scalable deployment of AI agents and automated microservices (e.g., event-triggered AWS architectures).

Whether you need to build an intelligent merchant feature, moderate user content automatically at scale, extract hidden insights from thousands of internal documents, or optimize your LLM pipeline infrastructure, I deliver production-ready code designed to scale.

Let's discuss how we can turn your data and business objectives into powerful AI solutions.
