By day, I'm an Aeronautical Engineer, which is just a very fancy of saying I'm great at making sure things that are supposed to fly actually do. I hold a degree in the subject, so my knowledge of lift, drag, and thrust is pretty good. By night (and sometimes, let's be honest, all the time), I’m a Space Sustainability Researcher. I work along an amazing team dedicated to understanding and improving every aspect of the universe to make Earth and space a better, more sustainable place. We present our findings at conferences because if you're going to lose sleep, it should be for the good of the galaxy! My mind is a wonderfully diverse landscape where designing, writing, singing, art, and yoga all play together. I have worked as a patent consultant, conducted 30+ patentability searches, designed components and worked on deep research across autonomous, software, agricultural, mechanical, and medical tech. When I’m not researching or designing components, I pursue a more grounded (literally) existence as a 200-hour certified Yoga Teacher. Yes, I can pinpoint a flaw in a jet engine design and teach you the proper alignment for a Downward-Facing Dog. My favorite things are Space, Airplanes, Nature, Art, and Yoga. I'm an eternal learner, a self-proclaimed "learning artist," and a creative writer on Medium, I share whatever the moon tells me to. I’m essentially a high-learning Wonder Woman who freelances on Upwork, committed to turning every project into a masterpiece and constantly expanding my toolkit. Need help with: Research (patentability, market, tech), Writing (Articles/ Summary/ Research paper/Stories/ Poems/ Creative), Design (SolidWorks, logo, analysis), Presentations (Canva, Microsoft PowerPoint), Video/Image Creation/Editing, Python/MatLab Coding, Transcription/Translation, or just about anything that requires a hyper-curious, detail-obsessed mind? I’m ready to assist with the skills I have and learn the once I don't have, through the process. I would love to help, learn and grow. Let's launch your project!

Most hardware startups hit the same wall: a great idea, a concept sketch, and no clear path to a working prototype. That's where I come in. I'm a mechanical engineer with 5+ years of R&D experience designing precision subsystems for some of the most demanding environments in manufacturing. I now bring that same engineering rigor to startups, researchers, and inventors who need real technical execution, not just advice. Here's what makes me different from most engineers on Upwork: I bridge hardware and software. I'm a full-stack developer too, and I use AI-assisted coding tools (Cursor) to build fast. If your product needs a sensor dashboard, a data pipeline, or an embedded control interface, I can build it alongside the hardware. I design AND build. I own 3D printers and fabricate physical prototypes in-house. You don't just get a CAD file, you can get a real part in your hands. I've shipped real products under real deadlines. My work has resulted in 30% cost reductions through DFM/DFA, cycle time improvements from minutes to seconds. What I work on: New product development: concept → CAD → simulation → prototype → manufacturable design FEA and CFD simulation: structural, thermal, vibration, and fluid analysis (ANSYS, MATLAB) 3D printing and rapid prototyping: functional parts optimized for your requirements DFM/DFA consulting: making designs producible, cost-effective, and reliable at scale Academic and research support: FEA, simulation, and technical writing for Masters and PhD projects Full-stack development: web apps, tools, and dashboards built around your engineering data Industries I serve: Robotics, medical devices, IoT hardware, consumer products, drones, UAVs, and academic research. I work best with clients who have a defined problem and want someone who can own the technical execution end-to-end. If that sounds like you, let's talk.
