How I Build Systems

Data First

I model the data before writing a single line of UI. Strong schemas lead to strong software.

UX is Logic

A chaotic backend creates a chaotic interface. I simplify complexity at the source.

Scale Early

Even small systems deserve robust architecture. I build expecting growth.

Featured projects

プロジェクト
Baixa pra Mim Momozi
Flask YT-DLP

Baixa pra Mim Momozi

An experimental API project using YT-DLP and FFMPEG made for a React Native android app.

The Challenge

Running heavy video processing (ffmpeg) and complex downloads directly on mobile devices drains battery and limits performance.

The Engineering

A robust Flask API that centralizes heavy processing on the server, delivering only the optimized final file to the mobile app.

Kori
Python Numpy Pandas

Kori

A recommendation system based on tf-idf and cosine similarity.

The Challenge

Finding relevant items in large datasets using only keyword matching often yields inaccurate results.

The Engineering

Mathematical implementation using TF-IDF and Cosine Similarity to understand semantic relationships between items and suggest accurate recommendations.

Sweet Home
Flask React TailwindCSS

Sweet Home

Extensible confectionery management system with stock control, POS, login system, and financial dashboard.

The Challenge

Confectioneries lose revenue and ingredients due to a lack of unified control between sales (POS) and inventory.

The Engineering

A complete visual ERP with a financial dashboard that connects product sales directly to automatic inventory deduction.

Waluna
Axum React Chakra UI

Waluna

Watch anime without things getting in the way.

The Challenge

Conventional streaming platforms suffer from cluttered interfaces, excessive ads, and slow loading times.

The Engineering

A modern web app focused on minimalist UX, using a high-performance Rust (Axum) backend for instant delivery.
