About

A little about me

I'm a data engineer from Nepal with a degree in Electronics, Communication and Information Engineering from Pulchowk Campus (IOE, Tribhuvan University), which I attended on a full scholarship.

Since 2023 I've been building ETL pipelines and data workflows for freelance clients on AWS, Databricks and PostgreSQL. I'm an AWS Certified Solutions Architect, and I'm currently deepening my skills in Spark, dimensional modeling and orchestration.

Volunteering & leadership

Oct 2025 — Oct 2025

Volunteer Science Educator

Engage Nepal with Science · Nepal Science Festival 2025 · Kathmandu & Jhapa, Nepal

  • Completed a week of training in Kathmandu (7–10 Oct), then spent a week delivering science workshops at 4 schools in Jhapa (13–17 Oct).
  • Taught students up to grade 10 through hands-on experiments: water rockets and balloons on a string to explain forces, skateboards for balanced and unbalanced forces, and introductions to programming and robotics.
  • I love teaching and sharing what I know, and I believe education is one of the strongest foundations for change and progress. These were two wonderful weeks.
