Eghosa Osayame
Analytics Engineer · Data Engineer · Founder, DataGST
5+ years in data, building scalable ELT pipelines, dimensional data models and BI on Snowflake, Azure, AWS and GCP, turning raw, multi-source data into assets people actually trust.
The last mile between a pipeline and an insight.
At Data2Bots I design layered ELT architectures (staging, intermediate and mart) on Azure, AWS and GCP, aligned with dbt best practice and powering dashboards and executive reporting. I have a strong bias toward data quality, documentation and models people trust. DataGST is the public side of that same habit: checking the numbers before believing them.
