A production digital library: diacritic-insensitive Arabic search, English full-text search, and semantic vector search over tens of thousands of passages — with row-level access control, an in-app CMS, and a reading experience tuned for dense scholarly text.

• ~66,000 passages are searchable across Arabic (diacritic-insensitive), English full-text, and semantic vector search.
• ~11,700 pages are statically pre-rendered, served from Vercel's edge with multi-layer caching.
• 47 test files (unit + accessibility + Playwright smoke) run in CI, alongside secret-scanning and a hardened Content-Security-Policy.

The engine behind the library: it scrapes heterogeneous sources, parses them into a clean volume → chapter → passage hierarchy, translates with context-aware LLM calls, gates output through two quality tiers, and uploads to Postgres — all crash-safe and resumable across long, flaky runs.

• 220 books processed and ~35,000+ passages translated and uploaded to the live library.
• Roughly 90% cost reduction on the cached prompt prefix via prompt caching, with per-book cost tracked.
• Long multi-hour runs survive crashes and resume with no lost work, thanks to atomic checkpointing.

• Keep an online assessment platform running during live, high-stakes exams — diagnosing connectivity, browser, and test-environment failures in real time and monitoring system stability.
• Analysed ticketing data to surface recurring failure patterns and recommended workflow changes that improved platform reliability; resolved 80%+ of issues at first contact.

• Frontline support for Australian Taxation Office systems; maintained 95% CSAT over 18 months while consistently doubling daily targets and mentoring new staff.
