I’m Vishal B, a Data Engineer and open-source contributor at Apache Airflow, with strong hands-on experience in building scalable batch and real-time data platforms. I actively work on and teach technologies like Airflow, Spark, Flink, Kafka, SQL, Iceberg, StarRocks, BigQuery, AWS, and GCP, focusing on how real production systems are designed, optimized, and maintained. I’m deeply interested in: Designing end-to-end data pipelines Streaming systems & lakehouse architectures Open-source technologies And helping engineers understand how things actually work in real companies Through my 1:1 mentorship, I help you with: ✅ Data engineering interview preparation ✅ Project and resume guidance ✅ System design and real-time pipeline concepts ✅ Mock interviews with honest feedback ✅ Career clarity and learning roadmaps My goal is simple: to bridge the gap between theory and real-world data engineering, and help you present yourself confidently in interviews and at work. If you’re serious about building a strong data engineering career, I’d be happy to guide you.
