e GUI + Web Application for Complex Dynamical System Simulator (Scientific Visualization) Project Description I am looking for an experienced full-stack developer to build a professional, user-friendly web-based GUI and interactive dashboard for a complex multi-variable dynamical system simulator. The application must allow users to: Run simulations with adjustable parameters Visualize key outputs including time-series plots, phase diagrams, equilibrium points, and topological regime maps Generate high-quality graphical and image outputs (PNG, SVG, PDF export) Load and apply the model to different scenarios/countries of interest via configurable presets or data import The tool is scientific in nature and requires clean, modern scientific visualization (using libraries such as Plotly, Matplotlib, or D3.js). The final product should feel like a polished research or policy-analysis dashboard — intuitive for both technical and non-technical users. Key Requirements Modern, responsive web-based GUI (preferably Python-based backend with Dash/Streamlit or equivalent React + FastAPI stack) Real-time or near real-time simulation and visualization Clear display of equilibrium states and system topology Ability to save, export, and share graphical results Secure user/session management Excellent code quality, documentation, and maintainability Confidentiality This is a highly confidential project. You will be required to sign a strict NDA before any detailed technical information is shared. The underlying model and its application are original and must remain completely private during and after development. Deliverables Fully functional web application (hosted or ready for hosting) Clean, well-documented source code User guide and technical documentation Export functionality for graphs and reports Testing and basic deployment support Skills Required Strong experience with scientific computing and data visualization (Plotly, Dash, Bokeh, or similar) Python (preferred) or modern JavaScript full-stack development Experience building interactive dashboards for complex models Understanding of dynamical systems / ODE simulation is a big advantage Professional UI/UX design sense Please apply only if you are comfortable with strict confidentiality and can sign an NDA immediately. I look forward to working with a reliable and skilled developer who can deliver a high-quality, visually impressive product. Budget and timeline will be discussed with shortlisted candidates.
