Senior Data Engineer

Scout • Freelance

Feb 2025 - Feb 2026 • 1 yr

Led a large-scale data migration from PostgreSQL to Snowflake that cut infrastructure costs dramatically while improving performance. - Migrated 250 million records from PostgreSQL to Snowflake using clustering strategies, preserving all table relationships and referential integrity. - Reduced monthly database spend from $4,000 to $40 by moving analytical workloads off PostgreSQL and leveraging Snowflake's columnar architecture. - Cut warehouse processing time from 84 hours to 2 hours through query optimization and proper table clustering. - Implemented Elasticsearch infrastructure to automate search and indexing for a rapidly scaling dataset. - Ensured smooth production operation as the platform's data volume continued to grow.

    Had an amazing experience with Usman! He communicated very clearly from the start and understood the requirements completely before jumping to a solution. The integration was completed successfully and the results are looking quite promising. I would highly recommended him for ChatGPT and OpenAI integration needs and will be hiring him again soon!
