Senior🎓
Top SchoolAlvin Yap is a Data Engineer II based in Toronto with 15 years of technical experience, blending software engineering training with a background in medical radiation technology and forensic science. He specializes in modern data platforms—migrating legacy systems to Snowflake, building telemetry pipelines, and optimizing ETL and query performance to reduce costs and improve operational insights. At HashiCorp and HelloFresh he delivered measurable impact (e.g., lowering Snowflake costs, automating forecasting workflows, and improving prediction accuracy) while documenting complex architectures for mixed technical and non-technical audiences. He pairs a user-centered, agile approach with hands-on skills in Databricks, AWS Kinesis, CI/CD, and SQL optimization, and mentors junior engineers through code reviews and one-on-ones. Unusually for a data engineer, his clinical and forensic background informs a detail-oriented, evidence-driven mindset for solving ambiguous product problems. He’s driven to refine existing systems into resilient, cost-effective data assets that surface clearer customer insights.
