Works on INAPROC (https://katalog.inaproc.id), LKPP's national e-procurement platform, inside a Turborepo monorepo of 13 Next.js apps and 11 shared packages on a federated GraphQL layer with schema-driven codegen.
Built the "Pencarian Pintar" AI search experience on the buyer app: a session-persisted toggle in the header, shown only to logged-in buyers and gated by a feature flag, which commits the AI mode into the search URL so results never change while the toggle is being flipped.
Shipped the semantic search path, where buyer queries are matched by embedding similarity over product name, description, attributes, specifications and category instead of exact keywords — scoped to office supplies and electronics — with an explicit strategy precedence and a plain keyword fallback for guests, empty queries and flag-off.
Built the personalized "Rekomendasi Untuk Anda" row on the first results page: products ranked against the buyer's own region, with the recommended cards highlighted using the design's gradient outline.
Bootstrapped unit testing for the buyer checkout scope with Vitest and Testing Library — ~450 cases across 80 files plus a reusable checkout harness — and introduced a Playwright happy-flow recorder that captures reproducible video evidence for reviewers and QA.
