About Me

Hi, I'm Shreayan. I was born and brought up in Mumbai. I am 27 years old. I am a fun-loving person who likes to travel, eat delicious food, meet new people, and listen to all types of music. I have graduated with a Masters in Computer Science from Johns Hopkins University. I love coding and my areas of interest include Machine Learning, NLP, and Data Science. I started coding in 2012 when my class teacher introduced me to it. My love for coding has only improved over the years. Call me a fanatic, but I'm crazy for all things related to Space and Astronomy. I love researching random stuff in Astronomy and Space, which often gives me existential crisis. My hobbies include playing video games, chess, football and cooking. In my free time, I also play various songs on the keyboard. Do check out my Instagram if you want to check out how I play the keyboard.

Career Objective

My goal is to pursue a career in Machine Learning and venture into a technological field where my ongoing learning skills can be utilized to organize, manage, analyze massive amounts of structured and unstructured data to create various algorithms using machine learning to meet specific business needs and goals, thus contributing to the growth of the organization.

Summary

I’m a Machine Learning Engineer with 4+ years of experience building and deploying production-grade LLM, NLP, and multimodal AI systems across research and industry. My work focuses on training ML models, token-efficient LLM optimization, agentic workflows, and scalable MLOps architectures that reduce costs, latency, and integration overhead at scale.

At Seagate and Johns Hopkins University (ARCADE Lab), I’ve designed LLM pipelines, RAG systems, and multimodal agents powering real-world automation - from surgical robotics to enterprise data intelligence. I’m passionate about LLM efficiency, distributed inference (vLLM, Ray), and full-stack ML system design (FastAPI, K8s, Airflow) that bridge cutting-edge research with robust, production-ready impact.

Skills

I started my coding journey in 2012, when my class teacher introduced me to it. My love for coding has only improved over the years. I started coding with Java in 2012. After that, I learned the basics of C and C++. Then I moved on to HTML, CSS and JavaScript to create fluid, mobile responsive and lightweight web applications. When I was introduced to Python by a friend, I immediately fell in love with this language, and it has been my favourite language since. I have dived deep into deep learning (pun intended) and started learning machine learning (also, pun intended) in Python. My area of research lies in Recommender Systems, OCR and NLP.
