About Me

Hydraulics meets Innovation

Engineer. Builder. Badminton player. Lifelong learner.

I'm a Hydraulic Engineer with 2+ years of professional experience specializing in hydrological analysis, hydraulic design, and GIS-based modelling for hydropower projects across South Asia, East Africa, the Caucasus, and Southeast Asia — ranging from 3 MW to 285 MW.

Beyond the engineering office, I'm the founder of toolsforengineers.com, a platform with 130+ engineering calculators, onlinegistools.com for browser-based GIS workflows, and civilfornepal.com, Nepal's leading civil engineering knowledge-sharing community.

I completed a 3-month Hydropower Project Design training in Sichuan Province, China, gaining hands-on exposure to large-scale Chinese hydropower infrastructure. I'm currently pursuing a Master's in Disaster Risk Engineering & Management with research in flood modelling and GIS-integrated disaster risk reduction.

Outside engineering, I represented Nepal in Badminton at the FISU World University Games 2021 in Chengdu, China — competing in Men's Singles against Slovakia on the world stage.
