GitHub Repository ↗Who I Am
I'm Sibusiso Nkabinde, a Full-Stack Developer from Pretoria, South Africa, focused on building backend systems, REST APIs, and cloud integrations that solve real problems for real businesses.
My path into software wasn't linear. I started with Mechanical Engineering at Ekurhuleni East TVET College, which gave me a strong analytical foundation. That curiosity for how things work led me to WeThinkCode_, where I earned an NQF Level 5 diploma in IT: Systems Development, covering OOP, multithreading, full-stack development, unit testing, and end-to-end deployment.
Today I work at Idea Pioneers, engineering API systems, automating workflows, and owning full release pipelines from staging to production across AWS, Google Cloud, and Vercel.
I'm always open to interesting projects and new opportunities. If you have a problem worth solving, let's talk.
Technologies I Work With
The tools and frameworks I reach for to build reliable, production-grade systems.
Where I've Worked
Real roles delivering real value, from API design to full release pipelines.
- Designed and developed RESTful APIs and webhooks in Node.js (Express) and Python (Flask / FastAPI), securing endpoints with JWT and API key authentication and documenting via Postman.
- Integrated APIs with internal systems and third-party services enabling real-time, bidirectional communication and workflow automation across platforms.
- Engineered an automated payslip system in Python that securely generates encrypted PDFs and distributes them via authenticated API endpoints, eliminating a manual monthly workflow.
- Set up CI/CD pipelines using GitHub Actions and managed deployments across AWS, Google Cloud, Vercel, and cPanel, owning the full release pipeline from staging to production.
- Built data-driven dashboards and dynamic forms backed by REST APIs, improving internal reporting accuracy and streamlining user input workflows.
- Conducted pre-release QA for mobile apps prior to Apple App Store and Google Play Store publishing, and diagnosed complex API integration issues to maintain uptime.
