About Me

Engineer by foundation. Scientist by pursuit. Most AI leaders arrive from one direction — either a research background that struggles with production reality, or an engineering background that never touches original science. Over 19 years, I've walked both paths.

The engineering foundation runs deep. I was part of the team that built Home Depot's enterprise customer rewards platform — a J2EE system serving 2,000+ retail stores, coordinated across Point of Sale, Finance, ETL, EDW, Tool Rental, and a 25-member offshore team. That's production software at national scale, years before ML was mainstream. Seaview Research, ServiceNow, Wiser Solutions — each added a layer: clinical systems, enterprise SaaS ML, real-time retrieval pipelines.

The science track runs just as deep. At Equifax's elite 10-person Data Science Innovation Lab, I designed the NeuroDecision Gen 3 algorithm — a monotonic neural network adopted across auto, mortgage, and utilities risk models globally. I analyzed 9.6 billion tweets to develop a weak supervision methodology that predated the field's mainstream recognition of programmatic labeling. Both became US patents.

My patented work in Explainable Neural Networks for credit scoring has been recognized across the US, Canada, Australia, and the UK, and attracted interest from regulatory bodies worldwide. This work — and the related Optimal Path Planning for Credit Score Improvement algorithm — was presented at the Credit Scoring & Credit Control conference at the University of Edinburgh, co-authored alongside Equifax Data Science PhDs.

Recipient of the EB-1A Green Card — a classification reserved for individuals of extraordinary ability in their field, requiring demonstrated national or international acclaim. Currently serving as Staff Scientist, Artificial Intelligence Research at Ensemble Health Partners, promoted within 5 months of joining.

ServiceNow
Sr. Software Engineer · Machine Learning
Embedded engineer to evaluate usage of machine learning within a product team at one of enterprise software's most recognized platforms. Extended products with machine learning capabilities in close collaboration with product management — building low-latency, memory-efficient inference prototypes designed to maintain strict SLA response times at enterprise scale.

Also prototyped a solution addressing data co-mingling legal concerns across multi-tenant enterprise customers — an approach to ML model isolation in shared infrastructure environments.

Equifax Inc.
Sr. Big Data Engineer (ML) · Data Science Innovation Labs
One of ten engineers in Equifax's elite Data Science Innovation Lab — the brain and nerve center of a global Data & Analytics organization. Worked closely with the Chief Data and Analytics Officer. Designed the patented Explainable Neural Network algorithm for credit scoring (NeuroDecision Gen 3), enabling effective model building for 150+ data scientists. Patented approach recognized in the US, Canada, Australia, and the UK — with interest from regulatory bodies worldwide.

In 2016, analyzed 9.6 billion tweets using Apache Spark to develop a novel weak supervision methodology — using cosine similarity search to automatically generate labeled training data from minimal human seeds. This work predated the widespread recognition of programmatic labeling as a paradigm, and was later patented (US 10671812B2, 2020).

Built a computer vision system using dlib C++ ResNet with iOS for face matching and shape prediction — demonstrated as a featured segment during the Chief Data and Analytics Officer's keynote at Equifax's global D&A Summit.

The Home Depot / (through TCS)
Software Technical Lead
Led the design and delivery of the user interface and RestFul Webservices for Home Depot's enterprise Customer Rewards platform ("Project Grizzly") — a J2EE system deployed across 2,000+ retail stores, requiring tight coordination across Point of Sale, Tool Rental, Finance, and Enterprise Data Warehouse teams. Coordinated a 25-member offshore team. Identified and resolved a significant company-wide security vulnerability, designing a solution subsequently adopted across the entire organization.

Also served as Software Technical Lead on the store-level Truck Rental integration with an external vendor — owning full project lifecycle from requirements through pilot and production. As part of my work at TCS, designed and patented a Recommendation Engine (US 11392840B2) — early in the AI/ML big data era — now deployed across multi-channel B2C retail experiences globally.

Built an autonomous agent to play the Nintendo Find Mii video game using computer vision. Implemented four distinct tasks at three difficulty levels each — avatar identification using SURF descriptors + RANSAC homography, look-alike detection using LARK-based face detection + SIFT descriptors, odd-one-out detection using sparse optical flow with Hough transform clustering, and fastest-mover tracking using a cumulative belief network with Markov assumptions across frames. Successfully solved 10 of 12 tasks. Completed for Fei-Fei Li's CS 231A at Stanford.
