A no-code Telegram bot builder: visual scenarios, a built-in CRM, payments through Stripe and Telegram Stars, AI replies and broadcasts.

I am a fullstack developer with 15+ years of professional experience. I specialize in building scalable SaaS platforms, high-load Telegram bots, and complex backend systems. I don't just write code — I help businesses turn ideas into working digital products: from database design to final user interfaces and system configuration.

I create and maintain my own SaaS products, which gives me a deep understanding of all lifecycle stages of an application: from user acquisition to infrastructure optimization under heavy load.

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.

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.

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.

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.

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.

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.

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.

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.

Principles that define my approach to every project.
Every line of code must deliver measurable business value. Beautiful code without business results is a waste of time.
You see progress every 3–5 days. No black boxes: you always know where the project stands and what comes next.
I use proven stacks, not trendy frameworks. Fewer dependencies — fewer support issues 2 years from now.
If a process runs more than twice a week, it should be automated. This applies to both my code and client business processes.
70% of my clients return with new projects or refer me. I build relationships, not close tickets.
Every project comes with documentation: architecture, API, deployment instructions. Without documentation, a project is dead.
Tell me about your project and your role. We will discuss where I can help: development, a technical review or working with your team.
