01 / What I do

Built with intent.
Designed for what’s next.

Development and growth belong in the same plan. I work across three connected areas to help your product move forward.

01

Mobile development

From the first product decision to a working app. I develop mobile applications with a clear purpose and an experience that feels natural.

02

App marketing

A good product needs a way to reach people. I connect app development with marketing, helping shape how your product is positioned and introduced to its audience.

EdTech products

Technology that makes room for learning. I develop and market educational products, bringing the learner’s experience and the product’s growth into the same conversation.

02 / How I work

A product mindset.
From day one.

A direct conversation. A clear direction. Decisions that connect what you build with the people you’re building for.

01

Understand the purpose

Start with your idea, the people it serves, and the problem worth solving. Define the scope before moving into development.

02

Build the experience

Translate that direction into a mobile or educational product. Keep the user’s experience at the center of development.

03

Connect it with people

Bring product positioning and marketing into the launch conversation, with a clear focus on the audience you want to reach.

03 / The person behind dats-dev
