Gus Gaidelevicius

WA Comprehensive Kids Cancer Centre

Built a Next.js and Payload CMS platform that keeps the public site statically generated while giving editors immediate updates. Wrote a custom ISR plugin that follows relationships across layout blocks, rich text, archives, and global content to refresh only affected pages, with scheduled publishing through Payload's jobs queue.

Built an image pipeline using S3-compatible storage, Sharp, and CloudFront, plus a backfill CLI to regenerate formats across existing assets. Implemented Algolia search by converting Lexical content into sections for faceted filtering across pages, resources, and support services.

Built a custom Azure AD authentication bridge between Better Auth and Payload CMS, using OIDC/PKCE, HMAC-signed session handoffs, and role-based access control. Added Gemini-powered page review and metadata generation in the CMS, streaming feedback over SSE and caching results to avoid repeated inference.

Normally

Designed and built a native macOS app in Swift and SwiftUI that automatically normalises audio across video libraries. Bundled FFmpeg for sample peak and EBU R128 loudness normalisation, with folder monitoring using security-scoped bookmarks and an actor-based concurrent processing queue. Added content fingerprinting, per-folder settings, external drive awareness, and retries for locked or failed files. Kept the interface minimal, with a transparent processing history.

AnkiForge

Designed and built a full-stack Next.js platform that turns varied document formats into Anki flashcard decks, from binary parsing through to export. Architected a server-side pipeline that converts unstructured content into SQLite-backed .apkg files using SQL.js and JSZip, with strict validation, rate limiting, and queuing. Integrated Google OAuth, Prisma/Postgres persistence, and Stripe billing to support user accounts, usage quotas, and subscriptions.

The Kids Research Institute Australia

Single-handedly overhauled a .NET MVC website built on a 2015 codebase, rewriting the vast majority of it under tight deadlines. Modernised the design, performance, and accessibility, including full keyboard navigation.

Migrated the build tooling from Node 4 to 20, working through years of breaking changes and long-deprecated dependencies with no supported migration path. Manually rewrote or replaced dependencies where needed, recreated internal tooling lost to a defunct private npm repository, and automated build steps to streamline deployment.
