01About

Engineer on the ground.
Builder in the code.

I'm Angel Mainali, a Civil Engineer operating at the intersection of complex structural design and engineering automation. Currently, I serve dual roles on the Shyam Khola Hydropower Project (7.2 MW): Assistant Construction Project Engineer at Gorkha Hydro & Engineering Pvt. Ltd. (Consultant) and Assistant Project Coordinator at S.K Energy Development Ltd. (Developer).

On the digital side, I don't just execute structural designs; I build the tools to execute them faster. From HajirBook (a GPS-geofenced site attendance & payroll platform) to AnchorBlock Pro (automating AEPC stability checks), my custom tools replace static, manual workflows with highly efficient algorithmic solutions.

My research has been published twice in 2025–26: WASH infrastructure resilience in Water Practice & Technology (IWA), and 3D non-linear pushover analysis of traditional masonry in Patan in the Journal of Engineering Issues and Solutions — generating fragility data showing collapse risk at PGA ≥ 0.1g.

Available for consulting in hydropower civil engineering, structural assessment, and computational tools — and for research collaboration on hydroinformatics and seismic vulnerability of Nepali heritage architecture.
