Clean backend architecture without overengineering.

Working Style

Hands-on execution with pragmatic technical decisions.

Product delivery and legacy rebuilds

Own projects

lab://independent-products

Independent products and side builds

Independent projects where I am not only the backend developer, but also the person shaping the product structure, screen flow, and presentation.

2 active products

Backend + product thinking

Personal ownership

AI-assisted astrology product

AstryHub

product://astryhub

AstryHub is a personal product where I am trying a simpler format for astrology: short readings, clear structure, separate natal and transit layers, and an AI chat on top.

AI chat Credits FAQ Glossary RU/EN

Why it matters

For me, this is an example of a real product, not just a landing page: it has its own logic, pricing model, content structure, and bilingual setup.

Open project

Independent storefront project

Instiles.online

product://instiles

Instiles.online is a separate storefront-style project where I spend more time on presentation: how to show the catalog, how to structure the screen, and how to move the user from the first block to action.

Storefront Catalog UX flow Content structure

Why it matters

It shows that I care not only about backend logic, but also about how a product looks, reads, and moves the user forward.
