▪ Front and app events ingestion from dedicated micro-service using Kinesis streams
▪ Data processing and normalization of more than 1000 tables in a streaming mode using Clojure Kafka
Streams application and an internal DSL library
▪ “Glue tables updater” migration from Clojure to Scala in an advanced functional programming way (using
Cats, IO monads …) which ensures 40% S3 cost saving by avoiding glue crawler full scans and updates tables
as soon as data is landed in the data lake
▪ Batch processing improvement by replacing AWS Batch jobs (written in clojure) by EMR jobs to gain in
concurrency, scalability and cost (~80% cost saving and 50 times faster)
▪ Data architecture design to simplify data processing by relying on MSK and kinesis and replacing legacy and
inhouse solutions by AWS managed services
▪ Tabular PoC implementation to ingest data from kafka topics to the datalake using iceberg format
▪ Focus on main data challenges: processing guarantee, data loss, late data load and schema evolution
▪ Alerts and data monitoring implementation via Grafana and New Relic dashboards
▪ ETL tasks scheduling using Airflow (deployed on MWAA) dags
▪ AWS resources deployment via Terraform
▪ CICD delivery using Jenkins pipelines
