Work History
Director, Machine Learning
EagleView Technology
5 2020 - Current
- Built a Machine Learning Center of Excellence in India consisting of data scientists, ML engineers and quality assessment professionals to deliver data driven products to a wide range of diverse customers in different industries including roofing, construction, insurance, government and solar
- Built an R&D team focused exclusively on Gen AI applications that leverage multi-modal Large Language Models (LLMs) and diffusion models to perform tasks such as change detection, attribute extraction, style transfer (leaf-on to leaf-off and vice-versa) from aerial imagery
- Engineered an internal ML orchestration platform using AWS SageMaker, NVIDIA Triton Server, and other Python utilities
- This platform streamlines data collection, model training, evaluation, and deployment, significantly reducing manual effort
- Innovated a suite of computer vision ML models, notably improving legacy process automation like roof and wall measurements, increasing drop through rate from 40% to 60% for roofs with less than 12 facets
- Developed a data derivative pipeline that extracts and stores a broad range of attributes (e.g., roof type, material, tree overhang) from aerial imagery in a graph database, enhancing upsell opportunities, especially in the insurance and construction sectors
- Partially automated the survey quality check (QC) process, reducing QC duration from 3 weeks to 2-5 days, ensuring faster imagery warehouse integration for customer access
- Spearheaded the development of Assess - EagleView's flagship drone based property survey product that automates anomaly detection on the roof e.g., hail, wind and crease damages
- Created autoDSM – instant generation of Digital Surface Model(DSM) from monocular aerial images through the application of generative adversarial networks (GAN) which saw a 25% increase of volume from our solar customers and generated new leads for us
Principal Data Scientist
Here Technology
10.2018 - 05.2020
- Led the development and delivery of ML models for the LiveSense mobile SDK, Here's premier on-road navigation and assistance product
- Successfully quantized and integrated models for Android and iOS (using TensorFlow-Lite and CoreML) across a wide range of mobile devices
- Played a key role in enhancing the change detection and place discovery pipeline by integrating detection, segmentation, and OCR models
- This innovation improved the pipeline's efficiency by over 10% in terms of ingestion time, focusing on extracting Points of Interest (PoI) from various video streams
- Implemented real-time bug detection models in HereTrue vehicles, significantly reducing redrives by 50% in Germany by identifying anomalies during drives
- Collaborated with engineering teams on extracting and validating point clouds of buildings from directional images using LiDAR data, contributing to the accuracy and reliability of spatial data
- Organized workshops, keynote sessions, and other knowledge-sharing activities, fostering enhanced collaboration and knowledge exchange across the organization

Aditya Birla MyUniverse
10.2017 - 10.2018
- Created a team of data scientists to develop ML models across different functions of the e-commerce and e-lending business
- Created a risk assessment engine to identify bad loans at sanction time which reduced the default rate by 18% over the next 6 months
- Built a credit card recommender system to customize offerings to the users which resulted in a higher conversion rate
- Developed face detection and similarity models for our instant e-KYC service API
- Collaborated and aligned ML efforts with other children organizations of Aditya Birla Capital
Senior Business Analyst
VMware Software
07.2016 - 10.2017
- Created price optimization models for a wide array of product offerings and specific bundles of products
- Created optimisation models for Special Pricing Form (SPF) threshold - an order amount above which our elite customer is offered bulk discounts
- Developed propensity to buy for our customer and propensity to sell for our sales partners to streamline the pricing model and marketing campaigns
Freelance Data Scientist
09.2009 - 05.2016
- Collaborated with the Organization of Economic Cooperation and Development (OECD) on a 2-year long project to analyze the survey results in Uganda for crop insurance pricing and incentive model using STATA
- Developed models in R to detect not-performing funds within a portfolio managed by a top Swiss hedge fund organization
- Worked on multiple data science and analytics projects for startups and small-scale companies through platforms like Elance, Upwork and guru.com
