Waqas Mehmood B.Private profile: Upwork shows its earnings only to signed-in members, so we check it every few weeks, not daily. MRR here is a rough estimate (Upwork's six-month earnings ÷ months active). Last read Nov 5, 2026.

I design, simulate and validate control systems — and deliver the technical documentation that makes the results defensible. Research engineer in vehicle dynamics and control. Tsinghua University, Design Engineering. Equally at home in a two-day tuning job and a multi-month modelling programme. CONTROL & DYNAMICS • Controller design and tuning: PID, LQR/LQG, H-infinity, sliding mode, MPC, robust and adaptive control • Vehicle and multibody dynamics: ride, handling, suspension, actuator and powertrain modelling • State estimation: Kalman/EKF/UKF, sliding-mode observers, sensor fusion • Stability analysis, LMI-based synthesis, frequency-domain design and validation SIMULATION & IMPLEMENTATION • MATLAB, Simulink, Stateflow, Simscape • Model-in-the-loop and hardware-in-the-loop testing, code generation, real-time deployment • Python engineering stack: NumPy, SciPy, control, CasADi, pandas • Digital twins and plant models for testing and validation ROBOTICS & AUTONOMY • ROS / ROS 2 development, navigation stacks, motion planning • SLAM, localization, mapping and perception pipelines • Autonomous vehicle and ADAS algorithm prototyping AI, MACHINE LEARNING & DATA • ML for dynamic systems: system identification, surrogate and reduced-order models, reinforcement learning for control • Predictive maintenance, fault detection and anomaly detection • Time-series and signal processing, experimental data reduction, statistical validation • Data analysis and engineering visualization OPTIMIZATION • Convex, nonlinear and multi-objective optimization; Pareto and trade-off studies • Parameter, topology and shape optimization; design of experiments • Genetic and metaheuristic algorithms • Integrated plant-controller co-design TECHNICAL REPORTS & DOCUMENTATION • Engineering reports, simulation studies, feasibility and trade-off analyses • Whitepapers, technical due diligence, state-of-the-art and literature reviews • Test plans, validation protocols and results packages • Publication-quality figures, plots and graphical abstracts to journal specification HOW I WORK I start by restating your problem as a model and a set of measurable acceptance criteria, so we both know what success means before any code is written. You receive commented source files, a reproducible simulation setup, and a written report covering method, assumptions, limitations and results — not a folder of loose scripts. WHY ME Most engineers can run the simulation or write it up. I do both to publication standard, which is why my work holds up when it reaches your investors, your client, or a certification body. Send me the system, the constraint you are up against and your deadline, and I will tell you honestly whether it is solvable in that window.
