Project_Portfolio
NEX SYSTEM
An experimental browser-based operating system exploring performance limits in web environments. Built with React, WebAssembly (AssemblyScript), and WebGPU to implement native-like processes, high-performance visual layers, and a fluid desktop environment.
SyG Software ERP Engine
A full-scale enterprise resource planning engine developed for distribution centers and large-scale clubs. Features optimized bulk data loading, strict transactional database schemas, and multi-layered security pipelines.
// Database transaction model
const result = await prisma.$transaction([
prisma.payment.create({ data }),
prisma.ledger.update({ where, data: { balance } })
]);CPP Interactiva
An interactive educational web platform designed to help students visualize low-level C++ concepts, memory allocation, and pointers dynamically in real time. Eliminates setup friction by running entirely in the browser.
int main() {
std::vector<int> mem = {0x00, 0x01, 0x02};
for(int x : mem) {
std::cout << "Address: " << &x << "\n";
}
return 0;
}reload_souls
An experimental audio visualization and sound generator architecture utilizing the Web Audio API. Explores real-time frequency analysis, oscillator sound waves, and fluid layouts in the browser.
