High-performance web development, Webflow & Custom
My Web Development process in Switzerland
Architecture & CMS
Webflow, Astro & Headless CMS
I deliver scalable, multilingual Webflow builds. Your marketing team gets a clean CMS for global updates, while the semantic code foundation is engineered to seamlessly integrate with modern agentic AI workflows.
Animations GSAP
Web Animations & GSAP Interactions
I integrate purposeful micro-interactions that guide user attention directly to your call-to-actions, keeping visitors engaged without slowing down the page.
API & Data
API Integration & Web Sync
I connect your web platform to any third-party API or data source. Sync all your external tools in real time through ultra-secure integrations.
Why me
Webflow when it fits, Astro custom code when it doesn't
Fifteen years of design judgement, a developer's discipline and an honest recommendation: Webflow when it's enough, Astro and the Sanity headless CMS when you need to go further.
Webflow or Astro + Sanity: the right tool for your needs
I don't sell one platform by reflex. Your team wants to edit the site without a developer? Webflow. Heavy data, APIs or a strict performance budget? We build on Astro and Sanity.
Semantic code and structured data from the first line
In Webflow or in Astro, every site ships with clean semantic HTML, a connected Schema.org graph and a structure Google and AI agents understand without effort.
Why invest in custom web development in Switzerland?
An SME website isn't a project you deliver and forget: it's a tool that has to stay fast, editable and easy to evolve for years. Development is what decides whether your site is still fast, still editable, and still cheap to change three years from now. Working with a dedicated studio like TONYTONY means the person who designs the page is the person who writes the markup: nothing is lost in a handoff, and there is one number to call when something breaks.
The same technical questions decide whether a site earns its keep: does it load in under two seconds on the connection a visitor actually has, can your team publish in French, German and English without calling a developer, and does your contact form actually land in the tool your sales people use. Those are build decisions, not design decisions, and they're made in the first week, not patched in the last.
Webflow, built properly
As a Webflow Certified Partner, I build Webflow the way it's meant to be built: a strict, documented class system, real CMS collections instead of forty duplicated pages, localisation set up from the start so /fr and /de aren't bolted on later, and interactions tuned so they still run at sixty frames on a mid-range Android. Your marketing person updates a case study on a Monday morning without opening a ticket.
Webflow is the right answer more often than agencies admit. It's the wrong answer when it becomes a workaround factory, and I'll tell you that before you pay for it, not after.
When custom code is the right answer: Astro framework & Sanity headless CMS
Some projects outgrow a visual builder: heavy data structures, custom client portals, complex product logic, or a performance budget Webflow simply cannot hold. For these high-performance builds, I engineer custom solutions with the Astro web framework paired with Sanity headless CMS.
The Astro framework is engineered for pure speed: it ships zero unnecessary client-side JavaScript by default, serving ultra-lean static HTML that achieves flawless 100/100 Core Web Vitals on mobile networks. Behind Astro, Sanity acts as the content operating system. Your editors get an intuitive, real-time structured workspace tailored to your exact publishing workflow—complete with visual previews and effortless multilingual translation management. The front end remains completely decoupled, ultra-secure, and free from plugin bloat or proprietary builder lock-in. Deployed on modern edge infrastructure with automated rebuilds on publish, an Astro + Sanity headless architecture means your codebase belongs to you from day one—complete ownership, zero black boxes, and sub-second load times worldwide.
This custom architecture is also where the site stops being a brochure and starts being digital infrastructure: AI automation that connects your CRM, booking system, ERP, or payment processors via direct APIs, so a lead captured at 23:00 is in your pipeline before you open your laptop. Motion is engineered with the same discipline: scroll-driven GSAP interactions tuned against a strict performance budget and respecting prefers-reduced-motion, never as superficial decoration.
Built for AI agents, not just browsers
People increasingly ask an assistant instead of scrolling ten blue links, and that assistant only recommends what it can read. I build sites that answer machines properly, with SEO and AEO baked into the foundation: JSON-LD structured data, a clean heading hierarchy, entity-mapped content, proper multilingual hreflang, and an llms.txt file that tells language models what you do and who you serve. It's the difference between being cited in an answer and being invisible in one.
And where it earns its place, the AI lives inside the product itself (an assistant that answers from your own content, a quote configurator, a content pipeline that drafts in your voice) wired to the model of your choice through the same API layer that runs the rest of your site.
Switzerland & international
Web development in Switzerland: fast, multilingual and in your hands
A good Swiss website speaks several languages, loads fast everywhere and stays easy to update. I work from St-Luc in the Swiss Alps with companies in Switzerland and further afield. Some need a Webflow site their marketing person can run alone, others need something custom, connected to their tools. We talk it through over a coffee or a glass of wine (or on a video call), and decide together.
Webflow your team can actually run
Certified Webflow builds with a documented class system, real CMS collections and localisation set up from the start. Your team publishes on a Monday morning without calling me.
Custom when you outgrow the box
Heavy data, product logic, an app on the same domain: that's an Astro or Next front end with a headless CMS, deployed on Netlify. Your repository, your hosting, no black box.
French, German and English, done properly
A Swiss business rarely sells in one language. Hreflang, localised URLs and a CMS structure where translations are content, not three copies of the same site drifting apart.
Built for AI agents, not just browsers
JSON-LD, semantic structure and an llms.txt that tells models what you do. When a prospect asks ChatGPT about your line of work, your site can be read and cited.

Technical FAQ
Clear answers on technology stacks, custom code, and CMS autonomy.
Webflow or a fully custom build: how do you decide?
By who maintains the site and what it has to do. If your team needs to publish without a deploy and the logic is content-driven, Webflow wins. If you have heavy data, product logic, an app on the same domain, or a performance budget Webflow can't hold, custom is honest. I tell you which before you pay.
Do I own the code and the project?
Yes, entirely. On Webflow, the project sits in your workspace and I'm a collaborator you can remove. On custom builds, the repository is yours from the first commit and deploys run in your own hosting account. No agency lock-in, no hosting you rent from me, no leverage. That test matters even more with AI site builders, some of which lock the result inside their platform. More in why your AI-generated website stays invisible.
What does "built for AI agents" actually mean?
Two things. Your site is readable by machines, JSON-LD, semantic markup, clean heading hierarchy, correct hreflang, an llms.txt that tells models what you do. And where it earns its place, AI runs inside the product: an assistant answering from your own content, or a quote configurator wired to the model you choose.
How long does a build take, and what does it cost?
Showcase Pro goes live in 1–2 weeks (CHF 1,900, up to 3 pages). SME Growth in 2–3 weeks (CHF 4,900, up to 8 pages, CMS included). SME Bespoke in 4–6 weeks (from CHF 9,900). Hosting and ongoing maintenance retainers are scoped transparently with the client during onboarding. Pricing is fixed per project, quoted after a short call, and split 50% at kickoff, 50% at launch. Why a custom build and a theme with your logo on it aren’t priced the same: what a website really costs in Switzerland.
Can you connect the site to our CRM, booking system or ERP?
Yes: that's most of what makes a site useful rather than decorative. HubSpot, Pipedrive, Airtable, Stripe, custom APIs, or automation layers like n8n and Make. A form submitted at 23:00 lands in the tool your sales people already open, instead of in an inbox nobody checks.
Can our team publish in French, German and English without a developer?
Yes. Multilingual is set up at the start rather than bolted on: proper hreflang, localised URLs, and a CMS where translations are content instead of three copies of the site drifting apart. Your editor picks a language and publishes, no ticket, no deploy, no developer.
