πŸ‘‹ Hi, I’m Toan Le

πŸ’» Data Engineer | Software Architect | Code Enthusiast
🍡 Runs on coffee, code reviews, and the occasional Spark job failure (on purpose… for testing πŸ˜‰).


πŸš€ About Me

I’m a data engineer with 10+ years of experience in building things that:

  • Move data from point A to point B (sometimes with a detour through C, D, and Kafka).
  • Make sense of petabytes of data without using ... Skynet ( πŸ’€ ) .
  • Turn messy lakes into beautiful, queryable, and secure data platforms.

Currently working at Mercedes-Benz AG on customer data platforms.
Before that: trivago, Shopback, startups, corporates β€” if it has code, I’ve probably been there.

Translation: If it stores, moves, or transforms data, I can make it faster, cleaner, and less likely to wake you up at 3AM.


πŸ› οΈ Skills I (claim to) have mastered

  • Languages: C#, Java, Scala, Python (and fluent in StackOverflow copy-paste).
  • Big Data: Spark, Kafka, Hive, Airflow, Presto.
  • Data Lakes: Delta Lake, Apache Hudi, Iceberg (yes, I can sink your Titanic of raw data πŸ›³οΈ).
  • Databases: Postgres, SQL Server, MySQL, MongoDB, Elasticsearch, Redshift.
  • Clouds: AWS ☁️, Azure ☁️ (soon Google Cloud, because why not?).
  • System Design: Microservices, ETL/ELT pipelines, messaging, CI/CD, distributed headaches.

πŸŽ“ Education

  • Master of Computer Science – Heilbronn Hochschule πŸ‡©πŸ‡ͺ
  • Bachelor of Computer Science – Ho Chi Minh University of Technology πŸ‡»πŸ‡³
  • Thesis topics: NLP, Computer Vision, and the art of surviving research with minimum sleep.

πŸ˜‚ Fun Facts

  • I believe in KISS: Keep It Simple, Stupid β€” except for coffee orders.
  • Data Lakes are like real lakes: beautiful when clean, terrifying when polluted.
  • I mentor junior engineers, but mostly so I can steal their new keyboard shortcuts.
  • My commits are 50% code, 50% dad jokes in comments.

πŸ“« Connect with Me

  • 🌐 LinkedIn
  • πŸ™ GitHub (well, you’re already here)
  • πŸ“§ Carrier pigeon also accepted, but response time may vary.

✨ Thanks for stopping by!
If you like SQL, Spark, or sarcasm β€” we’ll probably get along just fine.
