Hello! My name is Sunghwan Ki, and I am a Senior Data Engineer with 7+ years of experience in the finance industry, specializing in building large-scale, high-performance data systems used in real-world enterprise environments.

Throughout my career, I’ve designed and managed end-to-end data pipelines involving Kafka, Oracle Exadata, Hadoop, and Apache Spark, working with mission-critical, high-volume datasets that power analytics and operational systems for financial institutions.

I’m passionate about simplifying complex technologies and helping beginners build confidence through real, hands-on projects. My teaching style focuses on:

- Beginner-friendly explanations

- Copy-and-run practicality

- Real-world tools used in industry

- Step-by-step, no-stress learning

In my courses, you’ll learn how to build real-time dashboards, data pipelines, and cloud-based systems using AWS, Python, Kafka, SQL, PostgreSQL, and Grafana. You won’t just watch — you’ll build real, portfolio-ready projects from scratch.

I love seeing students go from zero experience to confidently running real-time systems on their own. If you're curious about streaming data, cloud engineering, or modern data stacks, you’re in the perfect place.

Let’s build your first real-time data project together.
