Data Engineering • Data Analytics
Data Integration • Data Quality • Data Governance • Lakehouse • Qlik + Talend

I build end-to-end data solutions with one non-negotiable principle:

data must be trusted to be useful

🛠️ Tech Stack

Platforms & Tools Qlik Talend Python SQL

Focus Areas: Data Integration • Data Quality • Data Governance • Lakehouse Architecture

🚀 Start here

Pinned: data-portfolio • qliktalend_demos • qlik • (anchor repo in progress)

🧱 Data Engineering

What I ship

  • Integration patterns (APIs, orchestration, incremental loads)
  • Reliability by default (idempotency, retries, error handling)
  • Data Quality gates (profiling, rules, exceptions, monitoring)
  • Governance-by-design (security mindset, lineage-ready structures)
  • Lakehouse patterns (bronze/silver/gold)

📊 Data Analytics

What I ship

  • Qlik semantic/KPI layers and reusable modeling patterns
  • Security rules (row-level access patterns)
  • Storytelling apps for decision-makers

🔥 Now building (anchor repos)

High-signal repos designed as 1 demo = 1 repo (architecture + setup + results):

  • de-link-analysis-demo — entity resolution + relationship graph (public-sector style)
  • de-data-quality-gates — profiling, rule severity, exceptions, reporting
  • de-lakehouse-medallion — bronze/silver/gold + incremental loads

✅ What you’ll find in mature repos

  • Context (problem + constraints)
  • Architecture (diagram + key decisions)
  • Data (synthetic dataset + dictionary)
  • Run it (reproducible setup, local and/or docker)
  • Results (screenshots/outputs + takeaways)
  • Trade-offs (limitations + what I’d change in production)
