I have a one page React site that is functionally complete but still looks a little unrefined on both mobile and desktop. I need a careful round of visual polish so the page feels consistently professional across breakpoints. Primary focus • Layout — tighten spacing and alignment so elements sit naturally in every viewport. No structural overhauls; just precise tweaks to existing flex/grid rules, margins, and paddings. • Typography — refine font choices, adjust sizes for readability, balance color contrasts, and establish a clear heading–subheading hierarchy. The codebase is a standard Vite/React setup with modular SCSS; you’re free to use plain CSS, Tailwind, or styled-components as long as the final bundle stays lean and easy to maintain. D...

I am developing an electrical-engineering project that revolves around control systems in MATLAB, with the spotlight on a full PID controller. The assignment covers modelling the plant, coding the proportional–integral–derivative algorithm, running time-domain and frequency-domain simulations in MATLAB/Simulink, and iteratively tuning the gains until the closed-loop behaviour meets standard performance indices. Because the emphasis is strictly on PID control, every step—from deriving the transfer function (or importing real-world data) to generating Bode, step-response, and error plots—must be documented so the workflow is reproducible. Control System Toolbox and Simulink are expected throughout; you are free to introduce additional MATLAB toolboxes if the...
