• Advanced experience with major public cloud platforms (AWS, Azure, or GCP) and familiarity with big data processing technologies (e.g., Kafka, Hadoop, Spark)
• Proven ability to create technical design documents, conduct architectural reviews, drive modular system design, and guide teams with strong execution rigor
