AI-first developer & product builder

Websites and products that make the next step feel obvious.

I plan, design, build, and test landing pages, web products, desktop apps, integrations, and automations — from the first brief to a usable result.

What I can help build

A clear site is a product decision, not decoration.

I bring the product, design, and delivery decisions into one focused process.

Landing pages & websites

Pages that explain the offer, guide attention, and make the next action easy to understand.

How I work

Clarity before complexity.

A practical process for moving from an open idea to something people can understand and use.

  1. 01

    Frame the problem

    Turn an open-ended idea into a clear outcome, constraints, and priorities.

  2. 02

    Design the route

    Shape the user journey and choose an implementation that fits the product.

  3. 03

    Build and refine

    Use AI tools for implementation while reviewing decisions and details with care.

  4. 04

    Test the result

    Check the important paths, resolve friction, and prepare a clear handoff.

About

A builder’s mindset with a marketing perspective.

I’m Andrei Tiumentsev, an AI-first developer and product builder based in Israel.

I work across the product cycle: clarifying what needs to exist, choosing how to build it, managing AI-assisted implementation, and staying with the work through testing and delivery.

I’m studying Digital Marketing at Ariel University, with expected graduation in 2027. That perspective helps me connect product decisions with the people a product needs to reach.
