Selected Projects

Work that best represents my technical profile

These projects show practical frontend work, systems-level development, build automation and independent product ownership. Capture is featured first as my strongest React and TypeScript proof point.

Capture browser-based sampler instrument project preview

Project 1

Featured web project

Capture — Browser-Based Sampler Instrument

Capture is an interactive browser-based sampler instrument combining a React/TypeScript frontend with a C++ audio backend compiled to WebAssembly.

React
TypeScript
Zustand
C++
WebAssembly
CSS

Built around a React and TypeScript frontend focused on responsive, performance-conscious interaction.
Uses Zustand to manage application and stage state in a way that stays lightweight and explicit.
Integrates a C++ audio processing backend compiled to WebAssembly for real-time audio work in the browser.
Combines modern web UI development with lower-level audio processing and browser runtime constraints.

Project 2

Grainiac — Granular Sampler

A high-performance granular sampler plugin written in Rust with an additional terminal user interface.

Rust
VST3
TUI
CI/CD

Rust-based plugin and application development with a strong focus on performance-sensitive audio software.
Includes an additional terminal interface, showing comfort with unconventional UI approaches beyond standard web stacks.
Structured around automated testing, builds and release workflows for repeatable delivery.
Demonstrates technical depth across DSP-adjacent code, tooling and deployment automation.

Project 3

OhMyGrain — Granular Delay

An independently developed granular delay audio plugin exploring experimental DSP techniques.

Rust
VST3
DSP
CI/CD

Built independently in Rust as a production-ready audio plugin project.
Includes automated testing, automated builds, code signing and deployment steps.
Shows end-to-end ownership from implementation through release and distribution.

Engineering & Development

Professional software engineering experience

End-to-End Development

In my current role at Metiundo in the energy sector, I develop features end to end across frontend, REST APIs, backend services, PostgreSQL integration, testing and deployment.

Frontend → REST API → Backend → PostgreSQL → Testing → Deployment

TypeScript · Node.js · Vue.js · PostgreSQL · Knex · Objection.js · Jest · GitLab CI/CD · Turborepo

This work is the clearest representation of my day-to-day professional stack: building real business software, integrating across layers inside a Turborepo-based monorepo and delivering features that need to be maintained over time.

State Machine

Recently designed and implemented a new state-machine architecture as part of a larger production system, modelling application states and transitions and integrating it into the existing application architecture.

I work comfortably on application structure, behaviour modelling and production-oriented implementation work beyond isolated feature tickets.

AI-Assisted Development

Practical exploration of coding agents in software workflows

I actively explore how coding agents and LLM-based tools can be integrated into real software development workflows. The focus is not on claiming AI expertise, but on using these tools pragmatically for faster iteration, better codebase exploration and more effective development automation.

AI-assisted coding, refactoring support and codebase exploration in larger projects.
Testing assistance, implementation scaffolding and support for repetitive engineering tasks.
Experimenting with agent-based development workflows and different coding-agent harnesses.
Working across local and cloud-hosted LLM environments depending on task, privacy and workflow needs.

Independent Software Development

Owning the full lifecycle, not just implementation

Since 2025 I have been independently developing, publishing and distributing audio software through timerift-audio.org. That includes both the software itself and the surrounding delivery pipeline needed to make releases available to users.

Idea → Development → Testing → Build → Code Signing → Deployment → Distribution

Rust-based software development for real products released under my own label.
Automated CI/CD for testing, builds and release preparation.
Code signing, deployment and software distribution workflows.
Operating personal server infrastructure and managing the practical side of shipping software.
Distribution through timerift-audio.org and external channels such as Muse Hub.

Background

Creative computing as a technical differentiator

I originally studied Music Production and later moved into professional software development. That background in music technology is part of why I build audio software and why I am especially interested in the intersection of creative tools, software engineering and interactive technology.
