Experience
Independent Software Engineer / Apple Platform Developer
- Designed, developed, and shipped 11 native applications across macOS, iOS, iPadOS, and watchOS, spanning productivity, developer tools, academic utilities, health/wellness, and creative workflows.
- Owned full product lifecycle: architecture, Swift/SwiftUI implementation, UI/UX, debugging, App Store Connect compliance, privacy documentation, product landing pages, user manuals, and release iteration.
- Published 8 products on the App Store, with Lumyna and Mathpedition scheduled to go live this week.
- Built local-first and privacy-focused tools with platform-specific interaction design, structured state management, file workflows, and native system integrations.
Audio Systems Designer / Sound Designer
- Led audio development for Deck Of Harvest, Backtrack, Shiyue, and Cyberslime, providing original soundtracks, sound effects, foley recording, synthesis-based sound design, and implementation-ready assets.
- Applied professional audio-domain knowledge to software and interface design decisions for audio tools, music systems, and creative-technology products.
Professional Audio Engineer & Music Producer — Alexxon
- Produced and released 50+ original tracks distributed globally, with support and features from Martin Garrix, Ferry Corsten, Anjunadeep Edition, and Monstercat Silk Showcase.
- Built a six-year professional production workflow covering composition, synthesis, recording, routing, mixing, mastering, release preparation, and visual/artwork coordination.
Selected Projects
- Designed and documented an agentic-network framework covering orchestration, protocol design, executor/reviewer roles, backend workflow drafts, acceptance criteria, and multi-agent coordination patterns.
- Structured a technical writing matrix for protocols, blueprints, coordinator logic, agent setup, tool usage, workflow improvements, and acceptance workflows.
- Built an interactive learning project explaining Independent Component Analysis through mathematical, visual, and audio-based interactions.
- Combined Swift/SwiftUI implementation with linear algebra, signal separation, interface design, and original audio-system work.
- Explored structural linear dependencies in handwritten digits using dimensionality reduction and statistical analysis of geometric digit fragments.
- Implemented experiments using Python, NumPy, scikit-learn, PCA, and linear-algebra workflows to study reproducible structure in MNIST digit data.
- Maintained supporting GitHub materials and an essay write-up for reproducible review.
- Led lifecycle development of an interactive dashboard visualizing Toronto housing disparities using census-related datasets.
- Engineered data-cleaning and harmonization workflows for disjoint variables across 2016–2021 datasets.
- Built a local audio sample and MIDI management tool using Python, SQLite, and PyQt for sorting and managing large-scale audio libraries.
- Designed file traversal and organization workflows for local-first creative asset management.
