Developed and validated a low-cost UV-LED + mini-spectrometer sensor for real-time dissolved organic carbon (DOC) monitoring in wastewater effluent percolating through soil biofilter columns, part of Master's thesis research into sustainable Managed Aquifer Recharge (MAR), conducted at the Chair of Urban Water Systems Engineering, TU Munich, under the supervision of Dr. Felicia Linke and Prof. Dr. Jörg Drewes. Highlights: • Built a flow-through sensor system using a UV-LED (365 nm), Hamamatsu C12880MA mi

Key Achievements Performed Under the Role: • Delivered EU- and IFC-funded water, wastewater treatment (WWT), RO, and energy audit projects for industrial facilities and 16 municipalities, achieving USD 59,000+ annual savings and 15% operational cost reduction through data-driven optimization. • Evaluated industrial and municipal water treatment facilities, ensuring compliance with environmental standards and wastewater discharge regulations. • Conducted water supply, RO, pumping, and energy assessments by

Key Activities Performed Under the Role: • Enhanced workshop output and capacity by refining workflows and eliminating bottlenecks, boosting efficiency. • Reduced downtime by 3 hours/per person/day through predictive maintenance analytics on equipment. • Increased efficiency by 35% with improved inventory management, minimizing waste and optimizing stock tracking.

Key Activities Performed Under the Role: • Got familiar with operating processes for converting and refining raw materials into products. • Collaborated in a professional team to solve productivity issues. • Enhanced collaboration between team members by preparing meeting materials and taking clear notes. • Created engineering documentation, consisting of assessments carried out using the cradle-to-gate approach.

Specialization in Urban Water Engineering & Energy Food Water Nexus For my Master’s thesis, I developed a low-cost optical monitoring system for measuring dissolved organic carbon (DOC) in Managed Aquifer Recharge (MAR) systems. The project combined NIR spectroscopy with an Arduino-based framework

Final Year Project: Fabrication, Instrumentation & Testing of Low Subsonic Open Channel Wind Tunnel The device is used to study the effect of forces (aerodynamics) due to high air velocity and measuring pressure at different points on the drag bodies. Small scale models of buildings, cars, air plan
