Research

Putting diamonds on-chain.

Technical Research Assistant Carnegie Mellon University · Remote · 2026 to Present

On-Chain Diamond Provenance CMU

Researching on-chain provenance for physical stones at Carnegie Mellon: scan each diamond's physical fingerprint onto a blockchain so it cannot be cloned and its history cannot be backdated. The authentication layer the trade has never had, and the same trade Jewellabs already serves.

Author, IEEE preprint 2023 to 2024

A CNN Approach to Robust Crop Health Monitoring Published

A convolutional neural network that diagnoses crop disease from images, which I built and trained with GPU acceleration and deployed at a local farm to lift yield through early detection. Published on IEEE's preprint platform with over 2,000 views and 100 downloads, and recognized with Technical Excellence awards from CREST Gold and IRIS.

Experience

Where I learned the trades.

Strategy and Technical Intern Diamond Plug LA · Los Angeles · 2025 to 2026

AI Agents for the Diamond Desk

At a Los Angeles diamond startup, I consulted for international stakeholders, using deep learning on historical sales data to tighten lab-grown diamond supply chains, predict design trends, and price B2B orders across Hong Kong, UAE, and LA, securing over 10 high-value orders.

Sales Manager J.K. Gems · Hong Kong and UAE · 2025 to Present

The Diamond Trade, Hands On

Sold natural and lab-grown diamonds, including CVD and HPHT goods, and priced parcels for firms across Hong Kong, Mumbai, Dubai, Bangkok, and Los Angeles. The trade Jewellabs now builds for, learned at the desk.

Technical Research Assistant UC Berkeley Haas · Remote · 2025

Quantitative Trading and Geopolitics

Analyzed private-equity and quantitative-trading data in Python and R at the Haas School of Business, studying how geopolitical shifts and fintech firms move stock volatility and trading behavior.

Digital Marketing and Social Manager Watchden · Hong Kong · 2025 to Present

Growth for a Watch House

Ran digital marketing and social for a Hong Kong watch company, across PR, ad campaigns, and both front-end and back-end web work to lift reach and conversion.

Operations Manager's Assistant Berkeley International Consulting · 2024 to 2025

Client Acquisition, End to End

Ran cold-outreach client acquisition, from lead generation to automated follow-up, contributing to closed deals with Genentech and Porsche.

Software Engineering Intern iCode · Mumbai · 2024

Full-Stack AI and Computer Vision

Built full-stack AI in Python with Django, Flask, NumPy, and Pandas: face-following drone navigation, CIFAR-10 image recognition on 60,000 images, and pathfinding for robotics, across Python, C, and Java. Around 30 programs in total.

Earlier building

Founded and shipped before college.

Founder and Executive Director Youth Environmental Action · New Delhi · 2024 to 2025

Youth Environmental Action

Founded a tech-enabled environmental policy initiative in peri-urban India. Built machine-learning diagnostics to estimate regional air quality and model mitigation for pollution hotspots, plus digital hubs linking stakeholders with policymakers.

Full-Stack Developer and Creator Carbon Footprint Calculator · 2024 to 2025

Carbon Footprint Calculator

A cross-platform app that recognizes vehicles, predicts emissions, and calculates the tree-planting offset for carbon neutrality, with a carbon-credit score for future trading. A donation funnel I built raised over $700.

About

The thread through everything is the same: take intelligence that works in a notebook and put it to work where money and materials actually move.

I study AI at Cornell. I have sold diamonds across Hong Kong, Dubai, and Los Angeles, priced parcels for the trade, analyzed private-equity and trading data at Berkeley Haas, published computer-vision research that runs on a working farm, and shipped an app to the App Store.

Now I build AI and blockchain infrastructure for the trades I grew up around. That means Jewellabs for the rare-metal and diamond world, founding engineering at Karalabs, information strategy at KOOV, and research at Carnegie Mellon on putting a diamond's physical fingerprint on-chain so it can never be cloned or backdated. I like problems where the model has to survive contact with a real operator, a real supply chain, and a real invoice.

Away from the screen: cricket, football, chess, and watches.
