The Proof — the website of mathematics tutor Firdovsi Deyyanov
A single-page site for Firdovsi Deyyanov, a mathematics teacher who prepares school leavers and olympiad students. Built with Next.js and running on a VPS; the entire enquiry flow goes through WhatsApp with a pre-filled message rather than a form.

When choosing a tutor, parents and students look for two things first: is there real academic training behind the teacher, and does it turn into results. A typical tutor listing says both in the same sentence — "experienced teacher, high results" — and shows neither. The site had to demonstrate those claims through structure, and then bring an interested visitor straight into a conversation without a long form.
- An academic visual language built on serif typography and an antique astronomical engraving
- A single page with five numbered sections: expertise, results, programmes, questions, contact
- Academic background: three degrees, the universities that awarded them and years of teaching
- Four areas of specialisation: olympiad maths, national graduation and entrance exams, SAT Math and AP Calculus, school curriculum
- A results section with four figures and a note stating the period they cover
- Student testimonials signed with university and year
- Three programme cards: format, what is included and a "most chosen" badge
- A seven-question expandable FAQ
- Every call-to-action opens WhatsApp with a message matching its context
- An office map on OpenStreetMap
- Structured data with Person, Course and FAQPage schemas
No enquiry form — WhatsApp instead
For a tutor, an enquiry form is effectively a dead end: a parent fills it in, waits for a reply and often messages another teacher the same day. On this site every button — consultation, enrolment, schedule — opens WhatsApp with a message already written. The visitor only presses send, and the tutor sees from the very first message which programme the conversation is about.
Structured evidence, not claims
Instead of writing "experienced teacher", the site lists degrees with the universities that awarded them, and results as concrete figures with a note on the period they cover. Testimonials are signed with university, field and year rather than just a name. Unlike plain text carrying the same information, this tells the visitor what they can actually verify.
The visual language comes from the subject itself
The site deliberately avoids bright "learning centre" colours: a paper background, a classic serif typeface and an antique astronomical engraving. Together with the headline — don't memorise mathematics, discover its logic — this language says on the first screen that the offer is academic mentoring, not a fun course.
Each programme is its own Course node
The three programmes on the page are declared in structured data not just as text but as separate Course objects, each with its own description, mode (on-site and online) and location, with the tutor linked to them as a Person. When search and AI systems look for an answer to "maths entrance exam preparation in Baku", they read the page as a list of concrete courses rather than generic copy.
Server mode, but not rendered on every request
The site runs as a Next.js server on a VPS, yet the page is prepared in advance and served from cache. Visitors get ready-made HTML and the server does not rebuild the page for each request. Server mode is kept so that dynamically generated files such as the share image and the icon are produced by Next.js itself, without extra tooling.
OpenStreetMap for the map
OpenStreetMap was chosen over Google Maps to show the office location. A single address pin needs no API key, no billing account and no heavy map script, and no third-party tracking code ends up on the page.
The site is live at firdovsideyyanov.az. The page is rendered ahead of time on the server and served from cache, while the tutor, the three programmes and the FAQ are declared to search engines as separate structured-data nodes. In PageSpeed Insights the site scores 92 for performance on mobile and 100 on desktop, with accessibility, best practices and SEO at 100 in both modes.
- Why is there no enquiry form on the site?
- It is intentional. Every button opens WhatsApp with a pre-filled message — the visitor does not fill in a form and wait, and the tutor sees from the first message which programme the conversation is about.
- What technologies is the site built with?
- Next.js, TypeScript and Tailwind CSS. It runs as a Next.js server behind nginx on a VPS, with the page rendered in advance and served from cache.
- What was done for search engines?
- Beyond the title and description, the page carries schema.org structured data: the tutor as a Person, each of the three programmes as a Course and the questions as an FAQPage.
- Who built the site?
- The site was built end to end — concept, design, frontend, structured data and deployment — by Nurlan Qadirov.
