Vani engineering

My Vani engineering showcase connects the live reader with legacy wiki modernization, typed corpus and MCP tools, and operational assessment methods.

The case studies distinguish the live reader, migration work with remaining acceptance steps, and local tool prototypes. They document my implementation and integration work while crediting the existing Vani platform, team code and editorial sources.

Implementation details

  • Web applications: model payments, ownership, moderation and expiry as separate states; test the boundaries.
  • Migration tooling: preserve source bytes, bind authorization to the intended account, checkpoint each outcome and reconcile uncertain uploads before retrying.
  • Frontend work: build responsive interfaces with keyboard navigation, consistent themes and explicit checks for broken links, missing assets and metadata.

EUJobs is a product I built and sold; its repository documents the current implementation. The ITCCK case study focuses on the migration software. Public examples use fictional data and exclude client mail and credentials.

Never knew I'd get into software! Started out with politics and law!
