Contributed to the development of Positive Duty v2, a multi-tenant compliance training platform used by over 70 organizations in Australia, designed to support the country's Respect at Work legislation.

I worked across the full product cycle in a full-stack capacity with a frontend focus — responsible for UI architecture, authentication flows, role-based portals (employee, administrator, superadministrator), reporting dashboards, and video training modules with progress tracking and certification flows.

One of my key contributions was designing and implementing an anniversary-based automation system that replaced manual spreadsheet tracking for mandatory annual training renewals — reducing operational overhead across all client deployments.

Multilingual website designed and developed for a Finnish therapist — independent client commission handled entirely from scratch, from visual identity to production deployment.

I was responsible for both the complete visual design and the frontend implementation: color palette, typography, responsive layout without CSS frameworks, and a calm, harmonious aesthetic aligned with the therapeutic nature of the client's practice.

The most technically interesting piece is the internationalization system: I implemented a custom i18n system in vanilla JavaScript with support for Finnish, English, and Swedish — without external libraries. Language switching activates a data-active-lang attribute on the body that controls content visibility via CSS selectors, with persistence in localStorage. Instant switching, zero dependencies, minimal footprint.

The project also includes full SEO metadata — Open Graph, Twitter Card, canonical URL, and robots directives — with structured data for indexing in all three languages. Deployed on Cloudflare Pages with a custom domain.

Project active in production.

Full-stack multimedia platform developed to accompany a doctoral research project at the Sibelius Academy in Helsinki, dedicated to documenting extended bandoneon techniques — combining a curated sound library, video demonstrations, academic articles, and podcast content.

This is an independent project I designed and developed entirely from scratch, meaning every technical and product decision was mine — from the database schema to the UX flows and deployment.

The most technically interesting part is the sound library pipeline: audio files are ingested into Cloudinary, converted and normalized, and served via a custom waveform player built with WaveSurfer.js, featuring infinite scroll, multi-tag filtering, and access-controlled downloads. The collection is also indexed for search engines using JSON-LD structured data.

Beyond the sound library, the platform includes a content management system for techniques, articles, and podcast episodes, with a protected admin panel for uploading and organizing content without touching the code.

Project active and under continuous development alongside the research progress.
