I am a Mechanical Engineer with over 10 years of experience in mechanical design, engineering analysis, manufacturing support, and laboratory equipment development. I work with industrial, research, and academic clients, delivering practical and production-ready solutions for small to medium-sized projects. My expertise covers the full engineering process, from concept development and 3D CAD modeling to FEA (Abaqus), detailed manufacturing drawings, and production support. I have led mechanical design and analysis for heavy-duty industrial equipment and optimized production line tools, fixtures, and assemblies with a strong focus on manufacturability and cost efficiency. I am highly skilled in SolidWorks, CATIA, AutoCAD, and Abaqus, and I design with real-world fabrication constraints, tolerances, and quality requirements in mind. I also have extensive experience designing and commissioning engineering laboratory and educational equipment, including fluid mechanics, HVAC, and control systems trainers. In parallel with industry work, I have several years of academic teaching experience as a Teaching Assistant, which has strengthened my documentation quality and communication skills—key factors for successful remote collaboration. Currently, I am pursuing my Master’s degree in Mechanical Engineering at Carleton University, Canada. I am open to remote small to mid-scale projects where accuracy, clarity, and reliable engineering delivery are essential.

I help building owners, developers, and design teams close the gap between how a building is modeled and how it actually performs — combining building energy modeling with mechanical (MEP) design to reduce energy use, operating costs, and carbon impact. Most freelancers do either the energy model or the mechanical design. I do both, which means the two actually align — and you don't need to coordinate between two separate hires. Why clients work with me: • Integrated energy modeling + MEP design under one roof • Code-fluent across ASHRAE 90.1, NECB, Title 24, IECC, BREEAM, and Passive House • Data-driven, fully documented, on-time deliverables 🖥 Energy Modeling & Sustainability EnergyPlus, DesignBuilder, IESVE, PVsyst · ASHRAE 90.1 / Title 24 / NECB / IECC compliance · energy audits (ASHRAE 211, ENERGY STAR) · 179D support · daylight, thermal comfort & PV feasibility studies 🏢 Mechanical (MEP) Design HVAC system design (VRF, AHU, chillers, boilers, heat pumps) · heating & cooling load calculations · plumbing, fire protection & gas systems · full Revit MEP modeling with clash detection · equipment selection, BOQ & specs 🏊 Specialized: Pool & High-Humidity Spaces Hydraulic design, equipment sizing, and HVAC for pool halls and spas 📊 Engineering Analysis & Automation FEM & CFD simulation · MATLAB modeling · Python automation for engineering workflows 📩 Let's bring your high-performance building vision to life — message me to discuss your project.
