Stellans' efforts resulted in faster and more efficient query execution, optimized ETL processes, and streamlined materialization processes. They delivered on time, navigated complex challenges, and maintained a high-quality standard. Their problem-solving and execution were impressive.

Describe the scope of work in detail. Please include a summary of key deliverables.

Stellans partnered with theSkimm to replace our Redshift warehouse with Snowflake, transitioning our entire data warehouse environment to improve performance, scalability, and cost efficiency. This effort involved mapping and migrating all existing data structures, including tables, schemas, and views, as well as reworking ETL processes to leverage Snowflake’s capabilities. We ensured compatibility with downstream tools and integrations, optimized query performance, and addressed security and compliance requirements throughout the process. The migration also included training our team to effectively manage and query the new platform while minimizing disruption to existing workflows and business operations.

RESULTS & FEEDBACK

What were the measurable outcomes from the project that demonstrate progress or success?

We evaluated and measured critical queries on our old Redshift stack to address performance bottlenecks and engineered improvements for Snowflake, resulting in significantly faster and more efficient query execution. ETL processes and build cycles were optimized to not only complete faster but also reduce costs, making operations more efficient and cost-effective. We ensured the data shape was spot-on for all required tables and streamlined materialization processes, leading to major gains in processing speed. These improvements hit our performance and budget goals, showing clear wins in efficiency, cost savings, and data accuracy.

Describe their project management. Did they deliver items on time? How did they respond to your needs?

They managed the project very very well, particularly given the challenges of working under pressure in an environment that required extensive reverse engineering of code and inherited artifacts. Despite these complexities, they were highly adaptable and responsive to our needs, consistently finding solutions to keep the project on track. When critical blockers arose, they were incredibly flexible, bringing in additional resources as needed to ensure progress. Remarkably, they adhered to the 12-week timeline, which was a tremendous achievement for a project of this scope and complexity. Their ability to deliver on time while navigating such a demanding environment was a clear testament to their expertise, commitment, and resourcefulness.

What was your primary form of communication with Stellans?

Virtual Meeting
Email or Messaging App

What did you find most impressive or unique about this company?

What impressed me most about Stellans is their deep, unparalleled expertise with the data technologies and platforms involved. They truly understand the nuances and complexities of warehouse solutions built on Redshift and Snowflake, and it shows in how they approach problem-solving and execution. Simply put, they get it and know how to deliver. Their ability to navigate complex challenges, reverse-engineer inherited legacy stacks, stick to a tight timeline, and maintain a high standard of quality is nothing short of amazing. Working with them was a great experience, and their depth of knowledge made all the difference.

Are there any areas for improvement or something Stellans could have done differently?

One aspect of the Stellans team that stands out is its impressive geographic diversity, bringing together unique perspectives and expertise from around the globe. While this diversity is a strength, it occasionally presents challenges in aligning communication styles, particularly when working on highly technical projects with tight timelines. Given their size, they went above and beyond to quickly address any communication gaps, so this is certainly categorized as a small adjustment. However, it would further build on an already strong foundation, making an excellent team even more effective and customer-focused.
