Senior Data Scientist & ML Engineer · Founder of Rantum · 6+ years in crypto (ex-0x Labs)

I turn messy, fragmented, and adversarial data into models, APIs, and products that ship — validated properly, not just prototyped. After ~4 years scaling core data infrastructure at 0x Labs, contributing to Dune's open-source Spellbook, and advising the Uniswap Grants Program, I founded Rantum, a senior data science & ML studio.

• Data products & intelligence APIs — enrichment, attribution, and predictive layers
• ML & predictive models — built and validated with point-in-time discipline and honest backtesting
• On-chain & crypto data (specialty) — execution analysis, cross-frontend attribution, MEV/labeling
• Fractional data/ML leadership — senior data muscle without the full-time hire

• ClearTrace — neutral, third-party on-chain execution intelligence: where DEX volume really originates across Ethereum, Base, Arbitrum & Optimism. Live API + dashboard.
• AddressIntel — predictive real-estate intelligence fusing fragmented municipal permit data with multimodal AI to score teardown probability and off-market opportunity. Live B2B API.

Technical deep-dives from the studio (full archive):

• ClearTrace: cross-frontend attribution — proving where DEX volume really originates
• AddressIntel: teardown-probability model — point-in-time ML on fragmented permit data
• On-chain entity resolution — naming the "Unknown Proxy" with a cheapest-first ladder
• Off-chain RFQ execution quality — scoring fills that revert under simulation
• Designing a point-in-time backtest you can trust — the discipline that separates a defensible model from a flattering demo
• Research: Cross-Frontend Attribution Methodologies in DEX Volume (whitepaper PDF)

• The DeFi Data Quick-Start: Reading On-Chain Truth with Dune Analytics — a short, hands-on guide: from a first Dune query to a dashboard you can defend. Every query in it runs against live on-chain data. Kindle edition; the companion page carries the live links, runnable queries, and errata.
