Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.
Don't let this gap widen
Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.
Organizations that don't train their talents on key topics see their competitiveness drop.
Every quarter without training is a gap widening with competitors who invest.
The cost of inaction quickly exceeds that of well-targeted training.
Quick installation of DuckDB in embedded and server modes, configuration of extensions for JSON and spatial data, hands-on CLI usage to import massive CSV, Parquet, and JSON datasets, practical exercises on creating persistent databases, initial Python connection via the duckdb library, initial benchmarks compared to PostgreSQL to measure speed gains, creation of a personal performance report.
Exploration of analytical window functions like ROW_NUMBER, LAG, and NTILE on real enterprise datasets, mastery of correlated subqueries and CTEs for hierarchical analyses, exercises on concrete BI cases such as customer cohorts or product ranking, use of dynamic pivots and JSON unnesting, debugging slow queries with EXPLAIN ANALYZE, creation of a prototype dashboard with exported results in simple visualizations.
Seamless DuckDB connection with Pandas for giant DataFrames without memory overload, integration with PySpark for batch/streaming hybridization, direct ingestion from S3, HTTP, and Kafka via extensions, hands-on workshops on complete ETL for an e-commerce dataset, advanced transformations with custom Python UDFs, scalability tests on 10GB+ data, generation of automatable scripts for CI/CD pipelines.
Vector indexing and columnar storage techniques for sub-second queries, configuration tuning for multi-threading and disk spilling, deployment in Docker containers for data microservices, workshops on real cases like fraud detection or real-time reporting, monitoring with Prometheus extensions, finalization of the ongoing project with performance optimization, export of certification models and production rollout plan.

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.
Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.
30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.
No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.
Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.
A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
