Shifa Shaikh

Data Engineer available for weekend freelance work: I design and ship Python ETL and data pipelines, build Flask REST APIs that serve ML outputs, and optimise PostgreSQL schemas and queries for production workloads. In prior work I reduced inter-service latency ~20%, cut query time ~30%, and improved API response time ~25%. I take small-to-medium projects with clear deliverables and can work with international clients. Contact me to discuss your project and get a clear plan and timeline. github
