01 · What I build

Open source at the intersection of data and AI.

Two flagship projects and a dbt package. Production code, published packages, real benchmarks.

OnlyMetrix

Governed metrics for BI tools and LLM analytics agents.

Your agent doesn't write SQL. Your data team does.

60/60Benchmark correct
100%Reliability
0Fabrications

A governed semantic layer and metrics platform. Turns dbt models and warehouse data into versioned, tested metric definitions that BI tools and LLM agents consume consistently. Native Lightdash integration, Python SDK, CLI, reliability layer, and dbt manifest sync.

Kanoniv

Identity resolution and AI trust infrastructure.

Splink-beating entity resolution at the core.

14Public repos
vs SplinkBenchmark
RustCore engine

A declarative engine for matching, merging, and mastering entity data across warehouses. Deterministic and probabilistic, benchmarked head-to-head against Splink on the same dataset. The platform also ships agent trust primitives: cryptographic identity, scoped delegation, and tamper-proof audit logs.

dbt-kanoniv

Open source dbt package for entity resolution.

Deterministic and probabilistic entity resolution inside dbt. Normalization macros, blocking keys, validation helpers, and analytics models. Benchmarked head-to-head against Splink on the same dataset with higher accuracy and throughput.

Agent Auth

Cryptographic identity and delegation for AI agents.

Sudo for AI agents.

Ed25519-signed delegation tokens that agents carry and verify. Scoped, revocable, and tamper-proof. GitHub Action for Claude Code, MCP servers, and CI/CD pipelines. Framework bindings for LangGraph, CrewAI, OpenAI Agents, AutoGen, and mem0.

03 · About

Systems that work in production, not just in demos.

I build data and AI infrastructure. My background runs across eight years in fintech, retail, and enterprise analytics.

I care about systems that work in production, not just in demos, and about building the governance and trust layers that let AI systems operate responsibly at scale.

Outside of work I am completing an MSc in Computer Science at the University of East London.
