Hey there! Thanks for visiting my webpage!
I am a Master's student at Carnegie Mellon University, specializing in Data Science. Previously, I worked as a Software Engineer (ML) at Microsoft on improving Search Engines at scale and improving the ranking and summarization of web search results using LLMs. I graduated from BITS Pilani with a bachelor’s degree in Computer Science and a minor degree in Data Science. I have worked on various projects involving deep learning, time series analysis, social network analysis, and NLP question answering, collaborating with prestigious institutions and organizations such as Seagate, JPMorgan Chase, University of Hamburg, and CSIR-CEERI.
I am excited about building tools for reproducible AI research, working on developing new algorithms and designing scalable software which will help in training, visualizing and evaluating machine learning models in real-time on static and dynamic datasets. I am proficient in C++, Python, C, Java, C#, R, SQL, Shell Scripting, Go, Scala, JavaScript and Swift programming languages, and have experience with frameworks such as PyTorch, Tensorflow, Keras, NLTK, OpenAI, Transformers, LangChain, OpenFace, Elasticsearch, AWS, GCP, Azure, Spark, Hadoop, Kafka, React, Angular, Kubernetes, Docker, Tableau, CUDA, A/B Testing.
Please feel free to reach out to me at mihirban@andrew.cmu.edu.

Experience
Software Engineer (Machine Learning), Microsoft
(July 2022 - Aug 2023)
Improving Search Experience for Natural Language Queries on Outlook Search:
Worked in the Microsoft Search team to improve the XGBoost Machine Learning ranking model for acronym search by adding a multigram matching feature with top user AI graph nodes. Achieved an offline precision (MAP) of 92% and improved the online Click-Through Rate by 24%, monitored via A/B experimentation.
Developed an end-to-end LLM-based summarizer with webpage summary and FAQs for Bing enterprise web search results by using GPT-3 with a scalable online query serving microservice and an offline time-based indexing service using OpenAI and Kubernetes.
Implemented the data pipeline of a profanity-filtering backend API for Outlook calendar search by using Apache Spark for
processing large-scale search logs from a sharded Cassandra database, reducing the search index loading time by 17%.
Machine Learning Engineer Intern, Seagate Technology
(May 2024 - Aug 2024)
Advanced Retrieval Augmented Generation for improving LLM generations:
I implemented an auto-merging retrieval approach with PostgreSQL logging in the LLM-based Retrieval Augmented Generation pipeline for a chatbot application with Azure AI Search, improving context relevance by 37% and answer relevance by 32%, evaluated using TruLens.
Quantitative Research Analyst Intern, JPMorgan Chase & Co.
(January 2022 - June 2022)
Building a Rating Migration Model with Z-Factor approach:
I worked in the Wholesale Credit Risk Team in Mumbai, India on building a Rating Migration model, using a Z-factor approach, which effectively converts a Rating Migration matrix to a single value with minimum loss of information.
I Developed a Time Series Rating Migration model to predict Z-values with macroeconomic scenarios by using Deep Learning models like LSTM, ARIMA and Support Vector Regression models using SQL, keras and scikit-learn, achieving an RMSE of 0.19.
Research Intern, University of Hamburg
(August 2021 - June 2022)
Enhancing Semantics in Pretrained Language Models:
I worked in the Language Technology Group with Prof. Biemann on fine-tuning BERT Pre-Trained Language Model for improving semantics-based question answering. We finetuned BERT with the knowledge graph mined from Wikidata and achieved a significant improvement on the GLUE score.
Software Engineering Intern, Microsoft

Projects
This is an Android application, developed in Java, using the Firebase database server. It has features to schedule Student-Professor meetings, a Laundry Management System and Cab sharing facilities.
This is an Online Cab Booking application designed for booking cabs as per the requirements of the customers. Developed in Java Swing, with MySQL as the backend server for the application. The communication between the server and the Java application happens through the JDBC Driver file. The application supports multiple customers simultaneously.
This is a Python application that conforms to a Client-Server architecture using the Shift Repeat protocol with a reliable UDP transport protocol. In order to implement reliability on top of UDP, we designed an application layer middle-ware protocol. The proposed protocol uses the 3-way handshaking concept to establish connections reliably. It uses timers, ACKs, and sequence numbers to ensure lost/corrupted packets can be recovered and delivered in order.
This is a Java application developed on the idea of Blockchain technology, which helps in maintaining a secure cryptocurrency exchange account for the users. The users are authenticated through a Zero Knowledge Proof problem. For a cryptocurrency transaction, the Elliptic Curve Cryptography algorithm is used to generate each user’s private and public keys in a KeyPair. The transactions between two users are then hashed with the public key of the organization and the transaction block is added to the history of transactions under the user authenticated.
This is an implementation of a compiler for a miniature programming language, 'C++++', which can parse a set of sequential statements, conditional constructs, loop constructs and functions. It has a DFA-based Lexical Analyser that recognizes the basic lexemes of the code written in C++++. The generated tokens are then output in the form of a Parse Tree. In case of errors the parser reports the errors and continues parsing.
