THAIHAUS SOM.

FROM HOTFIX TO ITS OWN PLATFORM.

Thaihaus Som (Thai restaurant in Upper Austria with loyal regulars) turned into a two-stage project. First the old Elementor site got cleaned up: four-second load time, PDF-only menu, broken mobile layout, exactly where reservations stall. What started as a fix grew into a full custom WordPress theme, and on top of it, TAMSANG, a tailor-made restaurant app for reservations, vouchers and delivery partners. They ordered a band-aid, got a kitchen.

OWN THEME. NO PAGE BUILDER.

• → Built from the ground up: WordPress theme with React Islands and Tailwind. No page builder, no plugin sprawl. One code base, one person responsible.
• → Mobile-first layout: over 80 % of guests come from phones. We design there first, scale up to desktop. Front page loads under 0.3 seconds, every image is Sharp-optimised (AVIF/WebP, three sizes).
• → Menu as structured HTML list instead of PDF. Google understands the dishes, allergens, prices. German, English and Thai in one system without WPML.
• → Self-maintainable: Christian swaps in new dishes, seasonal specials, photos and videos in the backend as easily as Word.
• → No Google Fonts, no trackers, no detour via US servers. All self-hosted, DSGVO peace from second one.

A BACKEND THAT THINKS LIKE A RESTAURANT.

The WordPress backend at Thaihaus Som isn't a generic "Posts–Pages–Media" editor. Dedicated sections for dishes (with allergens, spice level, price per size), daily-special banner, ambience gallery slots, event strip with auto-expiry, newsletter list and multilingual content (DE/EN/TH). Christian opens the matching input field, not a WYSIWYG desert.

• → Tamsang cockpit: open reservations, voucher sales, webhook logs at a glance in the dashboard widget. Admin bar shows open requests as a badge.
• → Encrypted secret vault: Stripe keys, Twilio token, POS credentials sit AES-256-GCM encrypted in the database. The admin shows masked values, never plaintext.
• → Custom roles for owner, service staff and casual help. Whoever updates the daily special at night never accidentally reaches the Stripe settings.

TAMSANG: THE RESTAURANT APP.

Tamsang is Thai for ตามสั่ง, "à la minute", made to order. That's exactly what the app does: it takes reservations, voucher purchases and delivery requests directly on the website. No Calendly, no OpenTable, no commission on every table.

• → Booking with slot logic: Christian sets time windows, weekdays, seats per slot and blackout dates. Atomic locking prevents double-bookings. Guest gets confirmation with a cancel link, no account needed.
• → Vouchers via Stripe Hosted Checkout: card data never touches the restaurant, PCI-SAQ-A instead of a full audit. Webhook plus cron reconciliation: triple safety, no paid voucher gets lost.
• → Order Hub as a React sheet: one button bottom-right, three tabs (Book, Pickup & Delivery, Voucher). JavaScript loads only when opened, not on page load. Wolt, Foodora and Lieferando as plain links, no data flow.
• → Modules toggle on or off: turn off Stripe, the voucher tab folds to a phone fallback. The site stays functional whichever module is currently live.
