David Joni

• Fully custom configurable-product interface inside WooCommerce, well beyond what any off-the-shelf plugin offers: multi-step forms, conditional pricing rules, validation, live preview.
• Custom component architecture with reusable form primitives, state hand-off between steps, responsive layouts tuned across breakpoints; integrated against the WooCommerce REST API for product data, orders, and persistence.
• On the same engagement, built a second custom product type extending WooCommerce's variable-product type, plus a swatches system from scratch when the original proposal missed a piece of scope.
• Built with the full Claude Code workflow: MCP servers for project context, custom hooks, OpenGrep for codebase search, marketplace plugins keeping the agent inside guard rails.

• Solo-built production SaaS, end to end: bulk domain availability across multiple TLDs from manual input, file upload, or AI-generated business-name suggestions. GDPR-compliant with tiered rate limiting.
• Backend: Laravel 13 + PostgreSQL + Redis on Laravel Octane (FrankenPHP) for low-latency request handling. Filament v5 admin with dashboard widgets (search volume, TLD popularity, top demanded domains).
• Frontend: React 19 + TypeScript + Tailwind CSS v4 + Shadcn/ui via Inertia.js v3. Server-Sent Events stream concurrent domain results with per-row loading, error, and available states.
• Engineering: 4-step verification cascade (DNS, RDAP, WHOIS over raw TCP port 43, paid DomScan API as fallback) cuts paid API spend roughly 90%. AI name generation via Cerebras + Groq (Llama 3.3 70B) with automatic failover.

• Custom WordPress theme built from scratch (no page builders, no templates), performance-tuned with WebP imagery, video hero, fast initial paint, semantic HTML, accessibility considerations. Full SEO foundation, GDPR-compliant cookie consent, GTM integration.

• Solo-built mobile app shipping to iOS, Android, and web from one codebase: Expo SDK 55 / React Native / TypeScript / Expo Router. Working dev build is feature-complete on core flows.
• Voice pipeline (turn-based REST): chose REST over ElevenLabs' realtime WebRTC/WebSocket SDK after persistent breakages from Expo + package-version updates made the SDK unreliable. Pipeline: expo-audio WAV capture, ElevenLabs STT, Claude Haiku, ElevenLabs TTS, base64 MP3 played back client-side.
• Backend, auth, payments: Node.js / Hono on Hetzner via Coolify. Clerk JWT integrated into Supabase as third-party provider with row-level security on every table. Stripe Checkout Sessions + signed webhooks for subscriptions and one-off upgrades.
• Security and GDPR: Supabase in eu-west-2 (London) for UK data residency. Consent flow before voice capture, on-device audio deleted immediately after upload, Varlock + 1Password secrets architecture keeping sensitive keys out of the client bundle by construction.

• Main frontend dev on the production web app for a UKRI / RICS / Google Cloud / NatWest-backed startup turning fragmented property data into real-time geospatial insights.
• Shipped Next.js 14 (App Router) + React 18 + TypeScript + Tailwind features: real-time WebSocket AI chat UI with auto-reconnect and connection-state UX, interactive Mapbox GL globe-projection map with polygon drawing and live area calculation (Turf.js), edge-authenticated Firebase sessions with custom Next.js middleware.
• Honest framing: this is where I onboarded into the modern React / Next ecosystem, bridging from my PHP / agency background into production Next.js work. It was built before I adopted Claude Code; every React / Next / React Native project since has used a Claude Code-assisted workflow (MCP servers, custom hooks, project-aware context).
