Olivier Manns

I am a Big Data Engineer with a strong background on Cloud, Data Pipeline design & deployment, and distributed computing. I have worked in the finance and automotive industry on many data development projects, from data extraction to data visualization tools. I also have experience on data science and machine learning subjects in Python. I have been working in both demanding production environnement and flexible innovation teams.

I have an engineering degree but I am a self-taught programmer who still loves to discover new state-of-the-art languages and frameworks. I also believe that sharing knowledge and helping others is one of the best way to grow and make a teamwork durable.

I am keen to help, develop and advise on your challenging data projects !

What I Do

Data Engineering

From requirements to production! Design, POC, developments, testing, deployments and monitoring of your data platform.

Performance Optimization

Big Data also means velocity! Tuning and optimizing your SQL queries, Spark jobs, ETL jobs,...

Cloud Data Architecture

From infrastructure-as-code deployments to cost optimization of distributed computing and managed services.

Data Visualization

Deploying the perfect visualization tool, matching both your needs and your data. Open Source (Metabase, Superset, Redash, ...) or proprietary (Oracle BI, Power BI, ...) tools.
