About Hamza

Senior Data & AI Engineer with 10+ years designing modern data platforms and production ML /
LLM systems on Google Cloud Platform. I partner with startups, scale-ups and large groups —
Spotify, Dailymotion, Kering, Limagrain, Blast Club — to turn data strategy into cost-efficient,
business-aligned products.
My expertise covers the full modern stack: data platforms (BigQuery, Dataform, Fivetran,
Dataplex, event-driven orchestration on Eventarc + Cloud Workflows), in-database ML (BQML,
Vertex AI, XGBoost, K-means), and agentic AI connected to business data (Google ADK, Gemini,
RAG, multi-agent systems). I also lead AWS→GCP migrations, data-mesh implementations, and
FinOps initiatives with measurable outcomes.
My conviction: data and AI create value only when they serve the product and business
outcomes. I combine architectural rigor, pragmatic delivery, and a clear focus on impact.

Experience

  • Limagrain
    Tech lead / Senior Data Engineer
    AGRICULTURE
    July 2025 - April 2026 (9 months)
    Paris, France
    • Designed the architecture of Limagrain's internal agentic platform on Google ADK / Vertex AI, supporting daily operations of the group's Data Platform (ODP): a multi-agent system (specialized agents for proposing, judging, reducing, verifying, and reporting incidents) that detects issues across 22+ monitored services (Dataform, Fivetran, Eventarc, BigQuery), classifies root causes (infra / code-bug / permission), correlates failures with recent commits, and generates actionable remediation steps, this includes Compass, an interactive ADK agent sharing the same tool surface and grounded in ODP documentation, runbooks, and naming / governance best practices (RAG), wrapped in a Next.js + CopilotKit chat UI — lets the data platform team diagnose incidents, get guidance on conventions, and unblock themselves on best practices without escalating.
    • Owned the LMC Finance data product end-to-end: designed and shipped Dataform pipelines, Cloud Functions, Cloud Run jobs, and the PowerBI semantic model feeding finance reporting — full ownership from ingestion to consumption.
    • Collaborated with the data platform team to roll out AI-assisted ops practices, reducing manual incident triage time.

    PRIVATE EQUITY
    January 2026 - April 2026 (3 months)
    Paris, France
    • Designed and shipped end-to-end data & AI platform on GCP (BigQuery, Dataform, BQML, Fivetran, Eventarc, Cloud Workflows): 30+ refined/golden tables, Eventarc-triggered Cloud Workflows orchestrating Dataform runs and 12 downstream Google Sheets refreshes on every Fivetran landing, CI/CD with gated compile + unit tests, Dataplex data quality and catalog — dashboard freshness reduced from 24h to 3h. Productionized a predictive churn model (BQML XGBoost, AUC 0.90): 50+ behavioral, engagement and transactional features engineered in-database, with segment predictions validated against ground truth.
    • Extended the ML portfolio on a shared feature store: unsupervised segmentation (BQML K means) for marketing cohorting, and NLP-based frustration detection using LLMs on call transcripts and support tickets to surface at-risk members early.
    • Built Blast Copilot, a conversational analytics layer on Gemini in BigQuery with a Dataplex business glossary and verified-SQL guardrails for Sales and Marketing.
    • Delivered the reporting and dashboard layer: multiple Metabase dashboards (engagement, app study, churn, retention, no-invest year 1) plus auto-refreshed Google Sheets connected to BigQuery for operational CRM teams — removed manual reporting work and ensured consistent metric definitions across teams.
    • Implemented end-to-end data governance: column- and row-level security via Dataplex policy tags, PII masking for analytics dashboards, GDPR-compliant access patterns.
