About

Full Stack Developer passionate about software architecture and engineering fundamentals. I value maintainable code, good design principles, and understanding the "why" behind technical decisions.

My focus is on backend and mobile development, though I work across the full stack. I think about long-term impact and approach problems with care and attention to detail.

Naturally curious — I enjoy exploring system design, architecture patterns, and deepening my understanding of computer science fundamentals. Always learning and improving.

Projects

Cleanser

macOS Storage Cleanup Tool

High-performance CLI tool that helps macOS users reclaim storage space by intelligently identifying and removing unnecessary files. Features dynamic pattern-based discovery to detect cache directories, build artifacts, and duplicate files across the filesystem using parallel SHA-256 hashing.

Implemented smart caching system, risk-based cleanup levels (Safe/Moderate/Risky), and configurable scan depths to balance thoroughness with performance. Published as a Homebrew package with comprehensive CI/CD pipelines.

Cymatic

Real-time Audiovisual Synthesizer

Browser-based audiovisual synthesis system inspired by cymatics — the study of visible sound vibrations. The application generates synchronized audio and visual patterns where the graphics directly represent the harmonic content being played.

Real-time audio synthesis with configurable harmonic layers using musical intervals. WebGL2 fragment shader implementing physics-based cymatic field equations with frame-perfect audio-visual synchronization. Built with immutable state architecture and pub-sub pattern for reactive updates.
