Ansbach, Bavaria. Work permit in place, full-time or part-time. Available nationwide, open to relocation. German B2 (telc), Ukrainian degree recognised by the ZAB.
I am a Full-Stack Web Developer and Automation Specialist with experience in automating business processes for real estate agencies, trading platforms, and enterprises. I have worked on solutions for property management, car sales, e-commerce, and other industries. My expertise includes JavaScript, TypeScript, React, Node.js, Docker, and SEO optimization, along with CMS platforms like WordPress. I started in system administration and in ERP development with 1C:Enterprise. IT support, Windows, hardware and local networks are still part of my experience, as are Google Ads, Meta Ads and web analytics.

What I Do

Web Development

Websites and web applications on TypeScript, React, Node.js and Astro. Most recently three sites for photography studios in Germany. One of them: 18 pages, no server, no database, no admin interface, and the address is nowhere in the code, so moving to the client's own domain takes no code change at all.

SEO Optimization

Technical SEO measured, not guessed. For adonsolutions.de I found why 17 keywords in the top 100 bring only eight visitors a month: the bottleneck is not the copy but 30 referring domains against 279 to 2,700 for the competition. For moest-fotografie.de I ran the move off Webflow without losing visibility, with Search Console set up before the move.

Automation

Automation where manual work stops being enough. For a regional property portal: 1,042,821 events recorded, hourly sync with two listing platforms, 2,789 posts published automatically, and ad videos built from property data. The enquiry rate rose from 1.9% to 5.9% along the way, with traffic unchanged. Alongside that, day-to-day operations: 29 websites on three servers, nightly backups, checks every five minutes.

WordPress Development

WordPress from the inside: custom themes and plugins, migrations, rescuing neglected installations. Most recently I took a section holding 436 entries from WordPress 6.4 to 7.1, together with Brizy and TranslatePress. Tested on a copy first, where I found and fixed a fault in the links, then applied with no downtime.
