About Rishi Aryal

15+ years of digital transformation leadership, software project management, and data engineering.

15+ Years Experience

Senior Data Engineer & Software PM

I am the Founder and Principal Consultant at PyLoom Technologies Pvt. Ltd., based in Butwal, Nepal. Over 15 years, I have architected, modernized, and delivered mission-critical data systems across South Asia and Southeast Asia for the World Bank, United Nations (UNDP, UNICEF, IOM), and national sovereign ministries.

Today, I balance executive technical project management with deep hands-on data engineering — building high-throughput PySpark pipelines on Databricks, orchestrating dbt in Snowflake, mapping clinical EHR/claims data to the OMOP Common Data Model, and integrating Generative AI & Prompt Engineering.

In addition to client consulting, I actively train the next generation of engineers as an Instructor in Python, AI/ML, Data Science, and DevOps at HUB IT Training and previously at Mahakavi Devkota Campus.
