Products I've built
from scratch
Side projects born from real problems. Each one is designed, built, and maintained by me — shipped to real users.
Muvize
Music Video Creator
Drop audio. Pick a style. Export video.
Muvize renders real-time Trap Nation-style spectrum effects from any audio file. Drop your .mp3, choose a background, pick a visual preset, and export the result as a video — everything runs in your browser, nothing is uploaded to a server. Built for aspiring music content creators who want to start publishing without expensive software.
Features
- Real-time audio spectrum visualization
- Trap Nation-style bar and waveform effects
- Multiple visual presets and color themes
- Export rendered output as video via WebCodecs API

- Dark, minimal aesthetic UI
Why it's built this way
Fully local processing
Your audio file never leaves your device. Everything — visualization and export — runs in the browser.
WebCodecs-powered export
Uses the browser's native WebCodecs API to encode and export video without any server-side processing.
No friction
Drop a file, choose a style, export. No installs, no waiting for uploads, no expensive subscriptions.
