Three.js Website Development for Premium Brands

Three.js websites built to a fixed price agreed upfront, working remotely from Leskovac, Serbia, with clients in the EU and beyond.

Get a quote All 3D services

Three.js website development where you deal directly with the person building the site. I specialize in scroll-driven 3D scenes, hero animations with custom shaders, and product configurators that ship as self-contained modules within classical HTML. How I work: the price is fixed upfront in a written offer (no hourly billing), the timeline depends on scope and is set in the same offer, and the full source code is handed over and stays yours. Common fits: SaaS product sites, e-commerce brands, and creative agencies pitching new business with a 3D portfolio.

Engagement model

Fixed price and timeline agreed upfront in a written offer, with no hourly billing. Revisions within the agreed scope are included. Out-of-scope changes are quoted separately before any work happens. No retainer required, no monthly minimum. Payment terms are set out in the same offer.

Technical foundation

Stack: Three.js v0.170 with GSAP for animation timeline, Lenis for smooth scroll, Vite for build, GLSL for custom shaders when needed. Hosting with a fast first byte, HTTP/2, Brotli compression and long-lived caching for static assets. Before launch I run a mobile Lighthouse test and send you the result.

Where it fits

This service is the right call when the brand needs a visual moment that sets it apart from the average competitor — agencies pitching new business, premium e-commerce, portfolios that need to look ahead-of-curve. If you need a basic content site or blog, a static-site generator without 3D is more economical and ranks just as well for simple keyword targets.

Timeline

The timeline depends on scope and is set in the written offer. I send progress notes in writing, so you always know where the project stands.

Frequently asked questions

Do you write technical documentation in English?
Yes. All deliverables — code comments, README, technical handoff doc — are in clean professional English. The site itself can be in any language; content is your responsibility, code and docs are mine and they're English by default.
How does payment work for non-EU clients?
The same as for everyone else — the written offer sets out the payment details for your situation, and everything is agreed in writing before work starts.
How long does this take?
It depends on scope. A simple site usually takes 1–2 weeks, larger projects take longer, and the exact timeline is in the written offer.
What does it cost?
Every project is quoted per scope — scene count, asset complexity and interactivity drive the effort. Send a short brief and you get a written fixed quote, with source code included.
What if my visitors are on weak phones?
The site detects device tier before the first scene loads and serves a lighter version on weak hardware (fewer particles, simpler shaders). Devices without WebGL get a static fallback that preserves the visual language and conversion path.

Privacy Policy

Last updated: 2 November 2026.

This document explains, in plain language, what data I collect, why I collect it and how I keep it. No fine print.

Data controller

The data controller is D. Svilenković. I run this site, so for any question about your data email dimitrije@svilenkovic.com or call +381 61 224 8989.

What data I collect

  • When you write through the contact form: name, email, phone, project type and description.
  • When you use the free website check: the site address, the email for the report and your name if you enter it. The report goes only to that address.
  • When you visit the site: basic visit info (which page, time on page, device and browser).
  • When you become a client: details needed for invoicing (company name, tax ID, address).

Why I collect it

  • To reply to your inquiry and offer a solution.
  • To deliver the work and issue an invoice.
  • To see which parts of the site are useful and improve them.

Legal basis: your consent for visit statistics, steps taken at your request before entering into a contract for replying to an inquiry, and a legal obligation for invoices.

Who I share data with

I don't sell your data or share it with third parties for marketing. I use Google Analytics for visit statistics, only if you accept it in the cookie banner, and the site is hosted on a netcup GmbH server in Germany (EU).

The form is protected by a check that runs in your browser and on this server, without third-party services: a short background calculation, a time token and a limit on the number of inquiries. Your IP address is not stored for this check, only a one-way record of it that changes every day.

How long I keep it

Contact-form inquiries are kept up to 24 months, the typical span of pre-sale communication. Invoice data is kept as long as the law requires (up to 10 years).

Website check requests are kept just as long as inquiries, up to 24 months. The technical result of the check, without your email, is deleted after 30 days.

Your rights

At any time you can ask what data I hold, request correction or deletion, or withdraw consent. Email dimitrije@svilenkovic.com and I'll reply promptly.

Cookies

Essential cookies remember your language and your cookie choice for up to 12 months. Google Analytics 4 (Google Ireland Ltd) loads only after you click “Accept all” and sets cookies starting with _ga for up to 14 months. Advertising features and Google signals are off, and statistics are kept for 14 months. Data may be transferred to Google LLC in the USA under the EU-US Data Privacy Framework. When you withdraw consent, these cookies are deleted.

Complaints

If you think something isn't right, write to me first and I'll sort it out quickly. You also have the right to complain to the Commissioner for Information of Public Importance and Personal Data Protection.

Changes

If something changes, I'll update this page and the date at the top.

Terms of Service

Last updated: 1 November 2026.

These terms describe how we work together. They're written in plain language — if anything is unclear, just ask.

Who provides the service

The service is provided by me, D. Svilenković, and I build the sites and apps myself. Contact: dimitrije@svilenkovic.com, +381 61 224 8989.

What I do

I build websites, web and desktop apps, online stores, Excel automation, appointment booking, system integrations, hosting and maintenance. I also make videos for social media, run Instagram, Facebook, TikTok and LinkedIn profiles, write posts and create AI images for them.

How we agree on work

  1. You tell me what you need. The conversation is non-binding.
  2. I send you a quote with the price and the timeline.
  3. When you confirm the quote, I start development.

Price and payment

The price is fixed and agreed upfront. You get the payment terms and the timeline in the quote before work starts. If the scope changes significantly, we agree on the new price before continuing.

Timelines

I give a deadline in the quote and stick to it. If I need material from you (images, text, access), please send it on time, because the deadline depends on it.

Revisions

Small revisions are included and done at no charge. Larger changes that go beyond the original scope are agreed separately.

Ownership

Once paid, everything I built is yours. You can use it, change it or move it to another developer without involving me.

Hosting and maintenance

I can host the site on my server and maintain it after it is built, and the quote states what that covers. You can move the site to another host at any time.

Liability

I do my best to make everything work as it should, but bugs happen. As soon as you report one, I fix it as fast as possible. My liability is limited to the amount paid for the project.

Cancellation

You can cancel at any time. You pay only for the work done up to that point, and receive all the materials and code you've paid for.

Disputes

If a disagreement arises, we'll first try to resolve it by talking. If that fails, the law of the Republic of Serbia applies and the court at the provider's seat is competent.

Changes to these terms

These terms may be updated. The last-updated date is shown at the top — you can always see what currently applies.
