Client log

a few quotes from 50+ projects since 2011

Our old WordPress site had a dated 2010s design, ran sluggishly, and generated almost no patient leads. Alexander completely revamped it and rebuilt everything on Nuxt: modernized the visuals, dramatically improved load speeds, and organized a patient-friendly service layout. He tuned our local SEO and GEO rankings across search and maps — the site finally started converting, and new patient bookings surged.

Dr. Mark VaizbuhMVDENT dental clinic, mvdent.co.il

Sasha built a fast, modern, and user-friendly website for our veterinary medical center. In emergencies, pet owners need immediate clarity to contact the clinic or request help — the interface solved this flawlessly. Thanks to local SEO and GEO optimization, new clients across the region consistently find us.

Dr. Ziv Dickmanveterinary medical center, zdvet.co.il

For our tour business in Eilat, the website is our main storefront and engine for direct bookings. Alexander developed a fast mobile-first site showcasing our buggy and ATV routes with online booking, and completely dialed in our local SEO and GEO visibility. We reached top positions in search and maps, generating a steady stream of tourists without middlemen.

Andrey TereshenkoU-Drive tours in Eilat, udriveeilat.co.il

Alexander created an outstanding website for our diving center: clear PADI course catalogs, dive spot guides, and an effortless booking flow. His SEO and GEO optimization delivered immediate results — tourists and divers visiting Eilat on the Red Sea find us right away on Google and Maps. A fantastic experience working together!

Our Magento store had become sluggish, hadn't been updated in years, and suffered security vulnerabilities that eventually led to a breach. Alexander stepped in and resolved the crisis: he seamlessly migrated the entire store from Magento to WordPress + WooCommerce, rebuilt the theme, patched all security loopholes, and maximized loading speeds. He also dialed in SEO and transitioned us to a much more cost-effective server without sacrificing any performance, significantly cutting our monthly hosting expenses. A true pro in e-commerce and web infrastructure.

Eli Ben YitzhakPresent Simple store, presentsimple.co.il

Working with Alex is a pleasure! Responsible, careful, quick and always available. Alex built the project from scratch: a complex multi-functional site with automatic registration, content at different access levels, international credit card payments and many other features.

Vladimir KozorovitskiCorset Academy, corsetacademy.netTranslated from Russian

All this time Sasha has looked after the technical side of all my projects. He has built more than 100 opt-in and sales pages, plus pages for launches and live conference broadcasts, and added a membership site for my paid programmes to the main site. … Sasha always does more on a project than I ask.

Ekaterina Alekseevaparenting coach, otnoshenyasrebenkom.comTranslated from Russian

Sasha has been fully responsible for developing the front and backend portions of my website, SuperKindClub.com and for a custom WordPress implementation for the blog for another site, SillyWise.com. … Sasha has suggested alternative pathways for development that I had not originally thought of and, by doing so, has effectively reduced the scope (and cost) of various projects.

Alex Karpmanentrepreneur, sillywise.com

He has built more than five large, important and profitable projects for me, both for Russian-speaking audiences and in the West, dozens of landing pages and much more. I trust him with running and supporting every project I have ever created and with launching new ones, and that says a lot.

How I Work

Principles that define my approach to every project.

  • Code is a Business Tool

    Every line of code must deliver measurable business value. Beautiful code without business results is a waste of time.

  • Transparency at Every Stage

    You see progress every 3–5 days. No black boxes: you always know where the project stands and what comes next.

  • Minimum Dependencies

    I use proven stacks, not trendy frameworks. Fewer dependencies — fewer support issues 2 years from now.

  • Automate Everything Repetitive

    If a process runs more than twice a week, it should be automated. This applies to both my code and client business processes.

  • Long-Term Relationships

    70% of my clients return with new projects or refer me. I build relationships, not close tickets.

  • Documentation is Part of the Product

    Every project comes with documentation: architecture, API, deployment instructions. Without documentation, a project is dead.
