Hi 👋, I am Dmitrii Semenov

Check out my website → here!

AI enthusiast & full-stack developer with a passion for building smart, end-to-end applications that solve real-world problems.

I’ve developed AI-powered apps from the ground up — like Nutrisha, an AI nutritionist, that uses FHIR patients’ health data to generate personalized diet plans and analyze meal images, and FoodFighters, an AI gamified app, that transforms nutrition from a chore into a game, making healthy eating accessible, engaging, and community-driven.

My journey started in Russia, where I won the national Big Change 2021 competition and became a WorldSkills finalist in Software Solutions for Business, receiving a $20,000 award. Since then, I’ve built desktop, web, and mobile apps with modern stacks like React, Node.js, TypeScript, Python, MongoDB and more.

After completing the Computer Programming program at Seneca Polytechnic, I’m now actively seeking full-time software engineering roles—especially where I can keep building powerful, human-centered AI solutions.

Let’s make tech easier, better, faster.
