About

I started with HTML in 2014. Now I build AI products 10–15 hours a day, from idea to production.

Now
Swiftin live, 1000+ users

I wrote my first code in 2014, HTML and CSS. Life pulled me into another field for a while, but it never let go: by 2023 I'd learned automation in Browser Automation Studio and dived deep into AI tools. For the last two years I've worked exclusively with AI.

Along the way I built my own product, Swiftin, the best proof that I can run a project end to end, from idea to real users. I'm driven by hard problems, automating routine, and taking a product all the way to production, from the code to the marketing. Self-taught: I pick up a new stack or domain fast and I don't quit halfway.

Away from the keyboard I'm a family guy: raising a son, don't drink. So all my energy goes to two things, my kid's laughter and green deploys. Same discipline as in my work: I finish what I start.

End-to-end ownership

Idea, architecture, build, launch, support, one person, the whole product.

Idea → MVP, fast

I dig deep into the business problem, then ship a working prototype quickly.

Where others give up

Reverse-engineering and parsing off the happy path, and new stacks without fear.

I finish what I start

No quitting halfway: I launch and I support. Self-taught, learn very fast.

Problem

The language barrier slows down reading, communication and language learning across the web, and ordinary translators are clunky and lose tone and context.

Solution

One browser extension that translates web pages (bilingual or translation-only), selected text, what you type in any field, video subtitles, and whole documents across 100+ languages, with AI voice, helping you communicate without borders and learn languages and grammar.

Result

1000+ users and growing, live on the Chrome Web Store, with a free plan and paid subscriptions.

Selected cases only. Details and NDA-restricted work can be discussed in an interview.
