Digital Experience

A premium product deserves a presence that carries it. I build digital experiences that don't just show but let people feel, from narrative scrollytelling to interactive product configurators, technically clean and maintainable. Specific tools are built spec-driven and AI-assisted, from a clear specification quickly to working, maintainable software.

WHAT YOU GET

• → Premium websites: full brand presence, performant and SEO-clean
• → Scrollytelling microsites: narrative and focused on a single product
• → Product configurators & shops: interactive, with Mollie/Stripe integration
• → Software development on demand: specific tools and workflows, built spec-driven and AI-assisted
• → Connected-product integration: dashboards, app and data interfaces for smart devices

PROCESS

1. Briefing call (30 minutes, free)
2. Concept, architecture and quote
3. Implementation with interim builds for review
4. Launch, handover and optional ongoing maintenance

THE TASK

A new product that needs explaining requires a presence that does three things at once: show the brand, make the product understandable and sell it directly. And all of that for exactly one product. Off-the-shelf shop systems are a poor fit here: too much platform overhead, running costs and template constraints for a single-product sale that must be legally sound (German button rule, GDPR).

APPROACH

A fully custom-built shop, tailored precisely to this one product: a static Astro site with targeted server endpoints. Fast, SEO-clean product pages, configuration and checkout without detours, and server-side price calculation where the amount shown is guaranteed to be the amount charged. Payments via Mollie, transactional order e-mails, content editing without a developer through a Git-based CMS.

CHALLENGES

• → Displayed === charged: every price component from one shared source for client and server (§ 312j BGB)
• → Bot defence without friction for real customers: honeypot plus rate limiting, IP addresses only as hashes
• → Content Security Policy with script hashes instead of blanket allowances
• → GDPR without a consent banner: no trackers, personal data only where needed and documented

RESULT

Live at transhover.com: a purchasable shop in German and English, without a cookie banner, with hardened security headers and a documented data flow, from first sketch to go-live from a single source.

TECHNICAL EXECUTION

• → Astro + TypeScript, statically generated with API endpoints on Netlify
• → Mollie payment integration: webhook with API re-fetch and idempotency claim
• → One Zod schema for client AND server validation, locale-aware error messages
• → Rate limiting and order store via Netlify Blobs, IPs only as SHA-256 hashes
• → CSP with script hashes, self-hosted fonts, transactional e-mails via Resend
