CTO / Solution Architect

Esnah
  • 09/2019 - 11/2020
  • Liège - Belgium
IOT / Communication gateway for aircrafts and boats
  • I created the distributed architecture for the solution to be scalable, resilient and performant using Docker Swarm for the orchestration and Apache Pulsar for the queuing/messaging system. APIs received the IoT data and serialized them in Apache Pulsar. Jobs consumed to data to perform different actions like quota management, statistics creation, etc..
  • I dockerized them to orchestrate them via Docker Swarm instead of the previously used pm2.
  • I automated the whole setup of the cluster via CI/CD (Gitlab) & Ansible: db mgmt, public keys deployment, deployment of the Traefik, Consul, Apache Pulsar, PostgreSQL, the tools around Docker Swarm, etc.
  • Finally, I created a bot in python and a mobile application in Flutter to work on both iOS and Android, with BLE.
Environment: Docker Swarm / Apache Pulsar / Ansible

Big Data and AI
  • With the help of the system engineer, I created the distributed architecture for the solution to be scalable, resilient and performant around Kafka. This architecture was composed of APIs to collect data serializing them in Kafka and Jobs that consumed the Kafka topics and produced results (like data cleansing, enrichment, featurization, ...) back in Kafka or a DB.
  • Implemented algorithms (a Cosine Similarity-like, RFV, ...) in SQL to answer <300ms with hundreds of millions of records.
  • I developed ETL jobs and PySpark jobs to process the collected data (to be used by the algorithms or to generate dashboards) and also developed librairies, APIs (using aiohttp) and Jobs in python.
Environment: PySpark / Docker / Kafka / Metabase
