Product-MindedFrontend Engineer.

React • Next.js • Tailwind|Translating features into revenue

I build frontend-heavy digital products with a strong sense for product direction, usability, and execution quality. My best work lives at the intersection of clean implementation, thoughtful UX, and the practical realities of shipping for startups and modern internet teams.

Behind the code.

// The Foundation

I'm Matej. Operating out of Slovakia, navigating the intersection of strict technical engineering and sharp business realities. While the industry focuses on syntax, I focus on the outcome.

My real advantage isn't just knowing React or Next.js. It's the ability to look at a product vision and immediately understand not just how to build it, but why it needs to exist. I build fast, scalable, and conversion-focused architectures that actually move the needle.

Product Ownership: From raw vision to scalable architecture.
High-End UI/UX: Bringing Figma designs to life without rendering compromises.
Rapid Execution: Shipping features securely and fast.

Whether it's integrating AI pipelines, building massive internal tools, or creating high-converting funnels — I bridge the gap between design and robust frontend engineering.

Portfolio

Selected Work.

Proof of execution. Core projects demanding absolute frontend logic, pixel-perfect UI, and product focus.

InstaView

Frontend execution for a startup product website built from an existing design direction.o

Designed for absolute precision. This project proves I can professionally collaborate on real client briefs. I can take someone else's design and translate it into high-level, production-ready code with absolute precision.

Proves high-fidelity UI translation & engineering execution.

Sústredené Dieťa

I don't just code pretty static pictures. I build systems that generate real profit and convert.

This is an end-to-end project. From the idea, through the psychology of the buying process, to the actual development.

Proves understanding of sales funnels, data, and conversion-oriented UI.

SkusSiTo

While others just record podcasts about AI, I use it to build e-commerce solutions from the ground up.

This project demonstrates technical curiosity and the ability to integrate artificial intelligence into a practical use case (e-commerce).

Proof of 'out-of-the-box' product thinking and complex technical execution.

AITesty

Bridging the gap between messy LLM outputs and robust, structured platforms.

An automated educational testing platform designed to reduce administrative overhead. Engineered a deep integration with Large Language Models to dynamically generate context-aware evaluations.

Proves backend capabilities and applied AI strategy.

Other Technical Work

Practical service platforms, trust-driven interfaces, and prototypes.
