Hey everyone!
I'm a 17-year-old high school senior interested in engineering, physics, finance, mathematics, and programming.
Over the past few years, I've been experimenting with different coding projects, mostly building interactive tools around subjects I'm interested in or things I'm learning in school.
I wanted to share some of them here and hopefully get feedback from people interested in programming, engineering, and STEM!

Engineering & Physics Simulators

Bridge Physics Game Experiment with bridge structures and explore how different designs behave. https://notivanly.github.io/BridgeGame/
Mini Wind Tunnel Simulator Explore how airflow, wind speed, and angle of attack affect lift and drag. https://notivanly.github.io/Mini-Wind-Tunnel-Simulator/
Truss Force Analyzer Analyze structural forces in trusses and visualize tension and compression. https://notivanly.github.io/Truss-Force-Analyzer/
Physics Sandbox Experiment with physics concepts and visualize how different variables affect motion. https://notivanly.github.io/PhysicsSandbox/
Planetary Gravity Explorer Compare gravitational acceleration, free-fall times, escape velocities, and jumping across planets. https://notivanly.github.io/Planetary-Gravity-Explorer/
Orbital Mechanics Simulator Explore spacecraft trajectories and how velocity and gravity influence orbits. https://notivanly.github.io/Orbital-Mechanics-Simulator/ Mathematics & Education
Calculus III Visualizer Explore multivariable calculus concepts through interactive 3D visualizations, surfaces, gradients, and vector fields. https://notivanly.github.io/Calculus-III-Visualizer/
Probability Lab Run probability experiments, simulate random events, and compare theoretical versus experimental results. https://notivanly.github.io/Probability-Lab/ Productivity
Smart Assignment Planner Organize assignments, track deadlines, and plan study sessions. https://notivanly.github.io/Smart-Assignment-Planner/ Finance
Investing Application An experimental finance-related application combining my interests in investing and software development. https://notivanly.github.io/Investing/ I'd love your feedback! I'm still learning, and these are personal projects rather than professional engineering tools, so some simulations use simplified mathematical models. I'd genuinely appreciate any feedback, especially on: Which projects you find most useful or interesting Features you'd like to see added Bugs, inaccuracies, or improvements you notice How I could make the interfaces more intuitive I'm hoping to continue improving these projects, especially the engineering and physics simulators. If you could only try one of these websites, which would you choose? 📝 Feedback Form I also created a short Google Form for anyone who wants to share more detailed feedback! Whether you have suggestions, found a bug, or just want to rate one of the projects, I'd really appreciate your input. Feedback form: https://forms.gle/bZr6XsSSYrEFLwSL9 Every response helps me figure out what to improve next. Thanks for checking out my projects!
