ADRIAN SZABŁOWSKIAI WEB DEVELOPER

I build software end to end, from native mobile to the browser.

AI Web Developer at Tidio. I work full-stack with React, Next.js, and React Native, from the data model to the last pixel, building web products and the AI-powered features inside them. I write about what I learn along the way.

What React Doctor caught in my portfolio, and what I ignored

I ran a static audit over my own portfolio the way I would over production code. React Doctor flagged twenty things. The real work was deciding which were real and which to overrule.

AI personal trainer

An AI personal trainer for people who want real programming without a human coach. Claude reads your goal, experience, and schedule, then writes a structured multi-week plan: which exercises, how many sets and reps, how much rest. You log every session with RPE, and at the end of each block the coach rebuilds the next one around how the last one actually went, adapting to reported pain or injuries along the way.

AI captions for short-form video

Drop in a clip and get word-perfect, animated captions in seconds. AI transcription comes back with word-level timestamps you can retime on a timeline and restyle from presets or your own fonts, colors, and outlines. Export a burned-in MP4 at the original size, or clean .srt and .vtt files. The video stays on your device. Only the audio is sent to transcribe.
