THE NAME

Kogaionon was the holy mountain of the Dacians — where Zalmoxis returned after studying among the Greeks, to teach his own people what he had learned. Seek the best knowledge. Bring it home. Build it properly.

DESIGN · TIER-02 — THREE ROUTES

Flexible design applies to my templates. Full custom design is billed separately — I propose one design with up to three iterations, we bring in a designer I trust, or you bring your own (BYOD). The surcharge depends on the route.

ADD-ON · TIER-01 & 02 — HOSTING

I run the site for you: hosting, domain & SSL, updates, monitoring. Optional — on monthly, quarterly, semi-annual or yearly plans. No database hosting: apps that need a DB run on a managed database service.

REVISIONS INCLUDED

Revision = change work on request: text edits, image swaps, small layout tweaks. Every plan includes a monthly hour budget.

€25/MO → 1H OF REVISIONS
€50/MO → 2H OF REVISIONS
EXTRA HOURS: RATE SET IN CONTRACT

Process

STEP-01

Discovery call

Free. We map what you need — if you're unsure, I counsel. We decide whether I host.

STEP-02

Scope & contract

Fixed quote, timeline, contract. 40% down books the build.

STEP-03

Work starts

Materials received — confirmed to you in writing. The delivery clock starts here.

STEP-04

Delivery & QA

You review the live site; we verify the 90+ Lighthouse score together.

STEP-05

Balance & keys

Balance on delivery. Code, content, domain — everything becomes yours.

You own everything.

On balance payment the full IP — code, design, content, domain — transfers to you, whole. During the build the code lives in Kogaionon repositories only; handover happens at delivery, complete.

Full IP transfer

Everything transfers on balance payment — no licences, no strings.

Contractual wipe

We contractually oblige ourselves to wipe every copy of your code and IP from our repositories and machines.

No lock-in

Even hosted with me, you can take everything and leave at any time — if over a quarter remains on your hosting plan, only the months beyond the first three are still billed.

Asked and answered.

How much does a professional website cost?

€1,500 fixed for a single-page template site, extra pages €250 each. A custom site — up to 5 pages, flexible design on my templates, integrations — is €3,000 fixed; full custom design is billed separately. No surprises: the price is in the contract.

Can I hire you as a freelance backend developer?

Yes — freelance backend engineering and consultancy is Tier-03. API design, TypeScript/Node ecosystems, Ruby on Rails, SQL & NoSQL. Remote, worldwide, lump-sum or daily rate.

Do you build MVPs for SaaS startups?

Yes. Scope to ship, A→Z: architecture, backend, frontend, deployment. One senior engineer by default, a validated senior team when the MVP needs more hands.

How fast will my site be live?

Template site: 7 working days. Custom site: 15 working days. The clock starts when I confirm in writing that all your materials are in — and every site ships with a Lighthouse score above 90, guaranteed in the contract.

Who owns the code?

You do — fully, on balance payment. Code, design, content, domain. We contractually wipe every copy from our repositories and machines. No lock-in, even if I host for you.

Can my site be multilingual?

Yes — custom sites include up to 2 languages, translated in-house for French, English, Spanish, Serbian and Romanian. Other languages: we set it up during the discovery call.
