Hello! Sinenhlahla Qiniso Nkosi: a Junior Software Developer with a BSc in Applied Mathematics & Computer Science.
I build backend systems and analytical tools with clear structure, elegant logic, and a little bit of flair.
Java is my main craft; I combine it with Python for data and Streamlit/Gradio for interactive demos.
| Domain | Skills |
|---|---|
| Backend | Java, OOP, REST APIs, Unit Testing |
| Data & Analysis | Python, Pandas, NumPy, Time-series |
| UI & Web | HTML5, CSS3, JavaScript, Streamlit |
| DevOps | Docker, Git, CI/CD |
| Soft | System design thinking, problem solving, quantitative reasoning |
Goal: Quantify and visualize how load-shedding affects economic output, municipal demand, and household behavior using real StatsSA datasets.
What I did
- Sourced and cleaned StatsSA electricity, municipal and GDP datasets
- Built time-series models (decomposition, rolling forecasts, regression)
- Measured correlations between load-shedding severity and sectoral GDP
- Built Streamlit dashboards and Gradio previews for stakeholders
- Packaged with Docker for reproducible deployment
Stack: Python, Pandas, scikit-learn, Streamlit, Docker
Short summary: a browser-based app for finding taxi fares, seat selection (SVG), QR payments, rank navigation, and safety information.
Built for real commuter usability with autocomplete, voice-search, and clean SA-inspired UI.
Stack: HTML, CSS, JavaScript, Node.js (local API), JSON route sheets, SVG seat layouts.
