During my time at IDOM in the Drainage team, I participated in the design, calculation, and writing of various projects, including:

• Sport Boulevard: Design of stormwater networks using Infodrainage software and writing of the technical report. Additionally, I provided technical assistance during the construction phase of the ongoing sections, ensuring the correct implementation of drainage systems.

• Port of Immingham: Executive project for the construction of two stormwater pumping stations. I carried out hydraulic calculations using EPANET and WANDA tools, optimizing the design for efficient stormwater management.

HS2 (High Speed 2) Birmingham, contributing to the hydraulic planning of high-speed rail infrastructure in the United Kingdom.

During my time at IDOM in the Drainage team, I participated in the design, calculation, and writing of various projects, including:

• Rail Baltica (Kaunas-Rymagala, Tallinn-Rapla, Rapla-Parnu): Design and technical supervision in the construction of the new railway line, covering sections of 78 km, 50 km, and 70 km respectively. Responsible for the design of longitudinal and transversal drainage systems, drainage in structures, 1D/2D hydrodynamic models, and hydrological studies.

• Laydown Areas in the Gulf of Aqaba (NEOM): Design of the sewage network, transversal works, and development of hydrodynamic models for perimeter channels, contributing to the planning of one of the region's most ambitious initiatives.

• ARAMCO Port, Saudi Arabia: Design of the drainage system for the new ARAMCO port dock and surrounding industrial areas, optimizing the project's hydraulic infrastructure.

• Second Ring Road and Thumama Road, Riyadh: Design and dimensioning of longitudinal and transversal drainage, as well as four pumping stations for the Thumama Road underpasses, improving the efficiency of the stormwater management system in key urban areas of Riyadh.

During my time at AECOM in the railways and infrastructure team, I participated in the design, calculation, and writing of various projects, including:

• Design and writing of the project for a retaining wall near the tracks. The design and modeling of the wall were carried out in WALLAP software due to the complexity of the selected retention system.

• Design of foundations for road signs along the railway line between London and Manchester.

• Design of new parapets for 5 bridges over the main railway lines in London.
