Umal Manjitha | Civil Enginner

Hi, I'm Umal Manjitha.

A

Motivated Civil Engineering undergraduate from the University of Moratuwa with strong technical skills in AutoCAD, Revit, HEC-HMS, Python, and SAP2000. Passionate about applying academic knowledge to real-world infrastructure projects and sustainable structural design.

About

I am a Civil Engineering professional with a strong background in structural design, geotechnical engineering, and hydrological analysis. I enjoy problem-solving and applying engineering principles to real-world challenges. I have experience working on projects involving soil retaining structures (soil nails), flood risk estimation, hydrological impact assessment, and architectural design, including column and beam arrangements for apartment floors.

Structural Design: Reinforced concrete structures, soil retaining structures (soil nails), beam and column layouts
Hydrology & Hydraulics: Flood risk estimation, hydrological impact assessment, river discharge modeling
Software & Tools: AutoCAD, HEC-HMS, HEC-RAS, ArcGIS, SAP2000, ETABS, Prokon
Programming & Data Analysis: Python, MATLAB, SQL, Excel (advanced)
Project Management: MS Project

Looking for an opportunity to work in a challenging position combining my skills in Civil Engineering, which provides professional development, interesting experiences and personal growth.
