    PR Card Renewal Platform

    Full Stack Development · PR Card Renewal

    BNBComps

    Short-term rental comps UI: URL filters, pruned payloads, short-lived cache.

    LeadBenji

    Automation Engineering · LeadBenji

    Website → normalize → validate → dedupe → export. Automation, not a model.

    Partial recrawls scale with failure count, not full site size. Junk rows are stripped before CRM import instead of in a spreadsheet afterward.

    ExactFitResume

    Resume-builder UI demo: live preview and wizard. AI, PDF, auth, and billing are simulated.

    Hostel Den

    Web + Mobile Development · Hostel Den

    Hostel bookings on one REST contract for Next.js admin and React Native staff tools.

    Staff and public booking share one state machine; concurrent edits lose in the API with a clear error instead of silent double-books.
