Rza H.

I help businesses build scalable, high-performance web applications that are reliable, secure, and ready for real-world use. I’m a Senior Full-Stack Engineer with strong expertise in React.js, Next.js, Angular, Node.js, Django, Laravel, and Python, specializing in backend architecture, API design, and complex system development. One of my key strengths is geospatial application development. I’ve built advanced mapping and data visualization systems using Mapbox, Cesium.js, Leaflet, and Google Maps API, along with 3D/web technologies like Three.js and WebGL. What I bring: ✔ Design and build scalable backend systems (REST APIs, microservices, auth flows) ✔ Develop modern, responsive frontends with clean UX ✔ Handle complex business logic, large datasets, and performance optimization ✔ Integrate third-party systems (CRM, ERP, analytics platforms) ✔ Take full ownership from planning and architecture to deployment I focus on writing clean, maintainable code and delivering solutions that are not just functional but scalable and future-proof.
