eSimplicity data engineers build modern data pipelines from scratch, and do not default to just custom solutions. All business data operation efforts require a focus on the user and user training/support. If users do not trust the data or know how to use the tools provided, adoption will not occur. eSimplicity works with your team during the discovery phase along with customers/users to better understand the business and user problems. We share lesson learned from customer experience in custom open source solutions and cloud-based automated commercial off-the-shelf (COTS) data pipeline solutions with an open architecture (e.g., Palantir, Trifecta, Snowflake, Databricks).
