About

I make databehave.

I'm a data engineer with internship experience, currently working full-time and opening up to select freelance work. I care about pipelines that don't break, models you can trust, and documentation future-you will thank present-you for.

The Process

Four steps from raw data to decisions.

01 / 04

Discover

I map the sources, the stakeholders, and the exact decision the data has to serve — before a line of pipeline code.

The Journey

From software, to data, to AI.

From building software to engineering data — and now the AI & automation layer on top. Full-time at Dusens Research, and open to select freelance work.

Based in Algiers

I'm from Algiers.

I architect systems that gather scattered data from sources all over the map — and bring it home: clean, modeled, and trustworthy.

The Architecture

From raw event to autonomous action.

One system across three disciplines — pick a layer and watch the data move through it, node by node.

Ingest → Lake (Bronze · Silver · Gold) → dbt → Star Schema → BI

Under the hood

Code when it counts.

Pick a discipline and read the real thing — typed services, data pipelines, and AI agents, wired up like the workflows I automate.

What I offer

Hire me for the hard, dependable parts.

From first event to final dashboard — and the automation that keeps it all running.

Data Pipelines

Batch & streaming ingestion that doesn't break at 3am — built on Airflow, Spark and Kafka.

Warehouse Modeling

Clean, documented, layered warehouses with dbt — Snowflake or Postgres, modeled to answer questions fast.

Quality & Reliability

Contracts, tests, lineage and alerting so the numbers stay trustworthy as you scale.

AI & Automation

Agents, models and self-running pipelines that turn manual workflows into systems that think.

Selected Work

Real systems, shipped.

Pulled straight from my GitHub — architecture, dashboards and models I built end to end.
