Hydraulic cylinder systems for one of the largest steel mills in the United States. Flow control on a 3-meter penstock at a major hydroelectric facility. 12 years designing mechanical systems that operate under real industrial conditions. I am a Mechanical Engineer and Business Administrator based in Medellín, Colombia, with over 12 years of experience delivering technical engineering solutions across hydroelectric power, heavy manufacturing, food & beverage processing, and industrial utilities. Every project in my background involved real operating systems (not prototypes or academic exercises). What I deliver: — Hydraulic Systems & Fluid Engineering: Design and analysis of hydraulic power units, high-pressure piping circuits, actuator systems, and flow measurement instrumentation. I have field experience with systems ranging from compact industrial hydraulic circuits to DN3000 pressure tunnels in hydroelectric infrastructure. I apply Bernoulli, Darcy-Weisbach, continuity, and momentum equations to real operating conditions, and I know how those systems behave when they fail (because I have been there when they did). — Structural & Mechanical Calculations: Beam analysis, anchor and bolt design, lifting and rigging calculations, steel structure verification, and FEA simulation for industrial components and assemblies. I produce engineering documents backed by my professional license (COPNIA AN230-113693, Colombia) (a legal credential that certifies every calculation I sign). — HVAC & Thermal Systems: Thermal load analysis, equipment selection, piping layouts, and system design for industrial and commercial facilities. My background includes boiler rooms, industrial heat exchangers, refrigeration systems, and combustion equipment (disciplines that translate directly into HVAC engineering and energy efficiency work). Tools I work with: AutoCAD · Inventor · ANSYS · SimScale · MATLAB/Simulink · Excel (engineering calculations & automated reporting) · Python (data analysis & process automation) How I work: I take projects from concept to documented deliverable (calculations, technical drawings, engineering reports, and bills of materials). I communicate in English throughout the project, provide clear milestone updates, and deliver files in the format your team needs. As a sole practitioner, you work directly with the engineer doing the work (not a project coordinator relaying messages). Representative experience: — Hydraulic power unit modernization, major hydroelectric facility, Colombia | 100/100 client rating — Hydraulic cylinder systems engineering, Nucor Steel USA | Heavy steel manufacturing — Industrial heat exchanger design, food & beverage processing plant, Colombia — Boiler room engineering and utilities design, industrial beverage facility, Colombia If your project involves mechanical systems that need to work under real industrial loads and conditions, I am the engineer for it.
