The Kronos Consultoria e Treinamentos website presents a workplace safety company based in Vila Velha, ES, Brazil, that serves businesses in Minas Gerais, Espírito Santo and Bahia. It shows the catalog of mandatory training, such as work at height, electrical safety, confined spaces, safety committees, fire brigades and first aid, and offers free study guides in exchange for contact details. It was built by André Gomes at NexiaLabs in PHP and MySQL with no framework, with a lead panel, on Hostinger hosting.
The client
Kronos delivers the training required by Brazil's workplace safety regulations, on site at the client, online or as tailored consulting. Its clients are companies in the Mucuri Valley in Minas Gerais, northern Espírito Santo and the far south of Bahia, from Teófilo Otoni and Nanuque to São Mateus and Teixeira de Freitas. Sales almost always begin with a WhatsApp conversation. The company wanted to be found by people searching for regulatory courses in their own city and to build a list of interested contacts.
The challenge
Safety training is a company purchase, with slow decisions and several people involved. A site that only lists courses does not start conversations: visitors leave without a trace. Kronos needed a reason for visitors to leave a name and phone number before they were ready to ask for a quote. And the team needed to see those contacts in one place, without relying on an inbox.
What was built
André built the site in PHP with pages for training, consulting, study materials and contact, and WhatsApp calls to action along the way. Each course shows its regulation, hours and format. The materials page offers study guides: one is unlocked by filling in name, phone and email, and the other requires referring three people, which multiplies the contact list. Downloads go through a script that checks on the server whether the referrals exist before serving the file. The team signs in to a panel to see leads and contact messages, with search and status filters.
What the system does
Training catalog with regulation, course hours and format: in person, on site or online.
Free material unlocked after entering name, phone and email, saved to the database without reloading the page.
Second material unlocked by referring three contacts, checked on the server before download.
Password protected panel to follow up on leads and contact messages, with search and status filters.
Contact form that emails the message to the team.
Professional service structured data with the address and the list of cities served across three states.
Strip of companies that trust Kronos and a process timeline from first contact to post training follow up.

Under the hood
PHP
MySQL
PDO
JavaScript
CSS
Schema.org
Hostinger
The site is framework free PHP with MySQL, served from Hostinger shared hosting. Pages share header and footer through includes, and the database connection uses a lazily created PDO instance. Lead capture is an asynchronous call that writes to the database and returns JSON, and each lead gets a token that identifies the referrals made from it. Material files are served by a PHP script, never by direct link, so the unlocking rule holds. The CSS is split into base, components and animations, with scroll reveals and a logo marquee.
Technical decisions
Free material in exchange for contact details, because training purchases are slow and the lead needs to exist before the quote request.
Referrals verified on the server by token, so the file cannot be unlocked just by tampering with the page.
Plain PHP on shared hosting, because the site needs little logic and sits on the same plan as the other domains.
Title and structured data listing the cities served, to show up in local searches for regulatory courses in each one.
