Hire the Best Simulation Freelancers
in Colombia

I am a dedicated and results-oriented freelancer with a proven track record in code analysis, code development, and computational modeling. My passion lies in deciphering intricate physical phenomena across diverse systems, including protein interactions, colloidal systems, polymers, and liquid crystals. I possess a deep understanding of numerical methods and code development and analysis. I am adept at tackling complex computational challenges, integrating theoretical concepts with practical implementation to ensure accurate and reliable simulations. I am a reliable and dependable team player, but I also work effectively independently. I am committed to continuous learning and staying at the forefront of advancements in computational modeling.

I help engineering firms and developers deliver accurate site development and utility designs using Civil 3D and BIM — from concept to construction-ready models. My core expertise is Civil 3D site development and utilities, including grading, corridors, pipe networks, and surface coordination. I also develop clean, well-organized Revit architectural models, aligned with site constraints, levels, and BIM coordination standards. I have strong experience in Scan to BIM workflows applied to Civil 3D, AutoCAD, and Revit, converting point clouds into reliable surfaces, alignments, and BIM models. My work is not limited to modeling: I focus on technical accuracy, constructability, and engineering logic to support permitting and construction decisions. Services I provide: • Civil 3D site development & utility modeling • Grading, corridors, and pipe networks • Revit architectural modeling (BIM-ready) • Scan to BIM (point clouds to Civil 3D / Revit) • Civil 3D ↔ Revit coordination I have completed 60+ projects with international clients, earning strong reviews for quality, communication, and dependable technical results. If you need a Civil 3D or BIM professional who understands real site conditions — not just software — I’d be happy to review your project.

I am pursuing a Master of Science in Mechanical Engineering. I have gained practical experience in both structural and fluid analysis through projects using SolidWorks and ANSYS, and I have developed extensive code in MATLAB, Python and C++. I have experience in academic writing, technical documentation, and complex document typesetting. In LaTex, I have experience with TexStudio and Overleaf, and the TexLive package. My professional experiences include working as a technical director in an automotive diagnostic center, as a maintenance and assembly engineer in a transport company, and as a technical research specialist, which has allowed me to translate complex technical developments into clear, concise insights. I am skilled at synthesizing detailed information into structured reports. My academic background includes extensive coursework in statics, material resistance, machine mechanics, machine design, mechanisms, fluid power, mechatronics, and different numeric methods such us FEM, VEM, BEM. During my master's program, I have taken courses in Engineering Modeling & Simulation, Design of Experiments, and the Boundary Element Method, which is highly relevant for structural analysis and studying crack growth. In my undergraduate studies, my thesis on supersonic nozzle design gave me a solid foundation in fluid mechanics and dynamics. My current master's work on crack growth in thin-walled pressure vessels further deepens my understanding of structural analysis. Thank you for your time and consideration. Best regards, Omar Fuentes
