About

Data infrastructure is our craft.

DataRazi is the trading name of DATA RAZI LIMITED, a data engineering and AI consultancy registered in England & Wales (company number 13169821) and founded by Ray Tarazi. We help organisations design, build, and optimise modern data platforms and AI systems — from Spark pipelines at scale to autonomous multi-agent systems.

Background

With deep experience across the data engineering stack — Databricks, Apache Spark, Delta Lake, streaming systems, and cloud infrastructure — DataRazi was founded to bring production-grade engineering to organisations that need their data infrastructure to genuinely perform.

We have helped teams optimise Spark jobs for 10–100× performance improvements, designed lakehouse architectures processing 50TB+ daily, and built quantitative trading systems that operate on live markets with real P&L.

Every engagement starts with understanding your specific architecture, constraints, and objectives — then applying proven engineering principles rather than cookie-cutter templates.

What We Believe

Production First

The best architecture is the one that stays reliable under load. We design for production from day one — monitoring, alerting, failover, and cost governance are features, not afterthoughts.

Measure Everything

If it isn't measured, it isn't managed. We instrument every layer — from Spark query execution plans to broker P&L — and use real data to drive optimisation decisions.

Systems Thinking

Data pipelines, AI systems, and trading infrastructure don't exist in isolation. We understand the full chain — from data ingestion to business outcomes — and optimise at the system level, not just individual components.

Clear & Accountable

Scoped deliverables, transparent pricing, and honest advice. We tell you what will move the needle and what won't, and we leave your team able to run what we build.
