Hi everyone 👋, I’m Andrii

Full-Stack Developer Websites & Web Apps

I am based in Ivano-Frankivsk, Ukraine. I help take ideas from concept to launch: shaping the interface, building the required features, setting up data flows and connecting external services. If you have an idea you want to bring to life, I can help.

What You Get

A complete product rather than disconnected pieces: a clear structure, backend logic, a responsive interface, the right integrations and a result that is ready to launch.

Full-Stack Web Development

Websites and web applications built end to end: backend logic, databases, responsive interfaces and everything needed for a stable launch. The result is easy to maintain and ready to grow.

A focused first version with the features needed to launch, show it to users and validate the idea before investing in further development.

Privacy & Cookies

How this website handles contact details, technical logs and cookies.

Effective 18 September 2026

1. Controller and contact

BuildByAndrew is operated by Individual Entrepreneur Andrii Dmytrovych Mahas, Ivano-Frankivsk, Ukraine. For privacy questions or requests, email [email protected].

This policy is intended to provide the information required when personal data is received in connection with a project enquiry.

2. Data processed

This is a portfolio and service website. It does not provide user accounts, subscriptions, payments or a newsletter.

Information you choose to provide

  • Your name and email address.
  • Project type, preferred timeline and project description.
  • Any information you include in an email or message sent through Telegram, WhatsApp, LinkedIn or Upwork.

Technical information

The hosting provider may automatically record limited server-log information such as IP address, browser or device information, request time, requested page and referrer. These logs are used to deliver and secure the website, diagnose errors and prevent abuse. They are not used here for advertising or profiling.

3. Project enquiries

The form does not submit data to this website.

Your entries stay in your browser until you press “Send request”. The button opens a pre-filled Gmail compose page or, if that is unavailable, your default email application.

When Gmail opens, the information entered in the form is passed to Google as part of the compose request. If you send the message, it is delivered to my Gmail inbox and processed to answer your enquiry, discuss scope and pricing, take steps before a possible contract, and maintain necessary business correspondence.

Please do not include passwords, payment-card details, government identifiers, health data or other sensitive information in a project description.

The legal basis is taking steps at your request before entering into a contract and the legitimate interest in responding to enquiries, maintaining correspondence and protecting legal rights. Where consent is the applicable basis, it may be withdrawn by contacting me.

4. Cookies and tracking

This website does not set cookies and does not use local storage or session storage. It does not contain analytics, advertising pixels, behavioural tracking or automated profiling.

The Manrope font is served directly from this website, so opening a page does not create a font request to Google. Ordinary hosting logs are not cookies.

Because no optional cookies are used, there is no consent banner. If analytics, advertising or another non-essential technology is added later, this policy and the consent mechanism will be updated before that technology is enabled where consent is required.

5. Service providers and external links

Limited data may be handled by providers needed for the website and communication:

  • The hosting provider processes technical requests and server logs to deliver and protect the website.
  • Cloudflare provides content delivery and security services and may process IP addresses, request metadata and network-error reports under the Cloudflare Privacy Policy.
  • Google processes information when you open the pre-filled Gmail page or send an email through Gmail, under the Google Privacy Policy.
  • Telegram, WhatsApp, LinkedIn and Upwork process data only when you choose to follow their links or contact me through those services, under their own policies.

Some providers may process data outside Ukraine. I do not sell personal data or share project enquiries for third-party advertising.

6. Retention and security

Project enquiries and related correspondence are normally kept for up to 24 months after the last meaningful contact. They may be kept longer when needed to perform a contract, meet a legal or accounting duty, resolve a dispute or protect legal rights. Data may be deleted earlier when it is no longer needed or after a valid deletion request.

Server logs are retained according to the hosting provider’s security settings and are not used for marketing. Reasonable technical and organizational measures are used to protect correspondence, but no internet or email system can be guaranteed completely secure.

7. Your rights

Depending on the applicable law, you may ask to access, correct or delete your personal data; object to or restrict processing; receive information about recipients; or withdraw consent where processing is based on consent.

Send a request to [email protected]. I may need enough information to verify that the request concerns you. You may also submit a complaint to the Ukrainian Parliament Commissioner for Human Rights or another competent supervisory authority.

8. Changes to this policy

This policy may be updated when the website, contact process, providers or legal requirements change. The effective date above shows when the current version applies.
