Work Experience

Founder & CTO at floatz.ai

July 1, 2023 - Present

Founded and architected a proprietary Knowledge Graph from scratch to power a Retrieval-Augmented Generation (RAG) system tailored for academia and R&D industries. Developed an agent-based scientific information retrieval system and a multimodal AI capable of adaptive reasoning across diverse information sources. Fine-tuned large language models to align with user profiles and implemented data pipelines for automated and manual data labeling. Established evaluation frameworks using precision, recall, F1, and ROUGE metrics. Led the product from architecture through scaling to 25,000+ users at institutions such as ETH Zürich, Stanford, and Oxford. Secured pre-seed funding, ranked in the top 10% of applications in a Y Combinator cycle, and established partnerships including with the ETH AI Center.

Researcher & Product Analyst at nChain

September 30, 2023 - August 4, 2025

Solved a critical blockchain scalability challenge by architecting a proof of concept in Rust that distributed Merkle tree creation, increasing throughput by 1000x for zero-confirmation transactions. Designed and prototyped a novel Multi-Party Computation (MPC) protocol to enhance data privacy which led to a successful patent filing.

Technology Analyst (Internships) at Morgan Stanley

December 31, 2014 - August 4, 2025

Worked in Equities Algorithmic Trading in 2013, optimizing a core trading engine search algorithm and boosting data retrieval performance by 10x alongside building a full-stack data visualization app. In 2014, developed a full-stack application for market data aggregation supporting sales and pricing teams in the Derivatives Trade Capture group.
