Portfolio release 1.0

Major 1.0 Release

On 30 August 2026, Leonardo launched the portfolio at leonardoprasetyo.com, with the first recorded successful deployment completing at approximately 5:21 pm Melbourne time.

Production Deployment

• Cloudflare hosting: Builds the Nuxt application through Nitro for Cloudflare Workers, with bindings for Workers AI, D1, R2, and Vectorize.
• Automated validation: GitHub Actions runs linting, TypeScript checks, the production build, and a Wrangler deployment dry run.
• Database migrations: Applies D1 migrations as part of the production deployment process.
• Controlled deployment: Deploys from main after validation succeeds and serializes production deployments.
• Production verification: Runs an HTTP smoke test against the deployed site to confirm it responds successfully.

PDF Ingestion

• Validated document uploads: Checks PDF signatures, file size, and SHA-256 checksums before processing. Original PDFs are stored in Cloudflare R2.
• Text extraction and chunking: Extracts text with pdf-parse, with Cloudflare PDF-to-Markdown conversion as a fallback. LangChain splits text into approximately 1,000-character chunks with 150-character overlap, preserving page references.
• Semantic indexing: Generates 1,024-dimensional vectors using Qwen3 Embedding 0.6B on Cloudflare Workers AI. Vectorize stores embeddings; D1 stores document metadata and authoritative chunk text.
• Verified publication: Confirms new vectors are available before activating the document. This release supports one active document at a time.
• Processing limits: Supports PDFs up to 10 MiB, 200 pages, 500,000 extracted characters, and 250 indexed chunks.

RAG Chat

• Semantic retrieval: Embeds each question with Qwen and retrieves up to five relevant passages from the active document using Vectorize cosine similarity.
• Verified source context: Reloads matching passages from D1 and checks that they belong to the currently published document generation.
• Streaming answers: Uses IBM Granite 4.0 H Micro through Cloudflare Workers AI and the AI SDK, with requests routed through Cloudflare AI Gateway.
• Document citations: Returns source filenames, page numbers, excerpts, and links to the relevant PDF pages.
• Public usage controls: Adds request validation, bounded conversation context, and a five-question daily allowance per network.

Public Document Library (read)

• Source browsing: Provides Library, Files, and RAG Database views built with Nuxt 4, Vue, and Nuxt UI.
• Document details: Displays filenames, file sizes, page counts, chunk counts, upload dates, and publication status.
• PDF access: Serves published documents through application endpoints backed by Cloudflare R2, including HTTP range support.
• Index inspection: Exposes the embedding model, vector dimensions, distance metric, and published vector count.
• Chunk previews: Provides paginated text previews with page references and embedding metadata.
