- Managed a $14M budget for OPEX, CAPEX, and inventory. - Led procurement, bid evaluation, and contracts for major mechanical upgrades, including turbines and gas systems. - Supervised a 12-person maintenance team (80 during overhauls), including welders, machinists, mechanics, engineers, and supervisors. - Expert in vibration analysis to detect and fix issues in pumps, gearboxes, and turbines; conducted dynamic balancing on fans and pumps up to 1300hp.

- Implemented a performance evaluation plan to ensure geothermal resource sustainability. - Analyzed the feasibility of reliability-based maintenance in geothermal power plants. - Managed 300+ personnel in the Production department. - Oversaw planning and execution of electricity production from two geothermal power plants (300MW capacity) in El Salvador.

- Optimized startup/shutdown procedures for condensing units and binary cycles, improving efficiency. - Coordinated maintenance to ensure optimal functioning of generating units, collaborating closely with maintenance teams. - Supported Berlin's Unit 3 reaccreditation as a Clean Development Mechanism under UNFCCC, contributing 44MW of renewable energy and reducing CO2 emissions by 140,000 tons annually.

- Supervision of Critical Maneuvers: Provided oversight during crucial operations in overhaul maintenance tasks to ensure precision and safety. - Maintenance Plan Implementation: Led the implementation of the annual preventive and predictive mechanical maintenance plan utilising CMMS MAXIMO (SAP PM). - Asset Procurement: Managed acquiring assets, tools, and consumables essential for maintenance tasks to enhance operational efficiency.

- Liaised with manufacturers to resolve design flaws, resulting in equipment replacements and eliminating recurring failures. - Performed dynamic balancing on 500hp pumps and fans, and approved operation tests for 1300hp multistage pumps at Goulds Pumps, NY. - Managed the redesign, procurement, and assembly of 40-ton geothermal water/isopentane heat exchangers, ensuring material suitability.

- Conducted stress simulations on mechanical components using Autodesk Inventor to enhance performance and durability. - Managed design, material selection, and execution of hydraulic and pneumatic systems projects. - Installed vibration sensors on cooling tower gearboxes, optimised measurement parameters, and oversaw rotor balancing and overspeed tests for an ORC turbine turboexpander in Florence, Italy.
