Creating websites and web applications
Modern web applications – from simple websites to complex online systems.
Technologies I work with
Solutions tailored to your needs
Online stores and API integrations
Simple and fast e-commerce platforms built with Rails, featuring payment integration, order management, and product catalogs. I integrate external services such as Stripe, SMSAPI, AWS S3, Google Maps, CRMs, and more.
Booking systems and admin panels
Online bookings with calendar, SMS/email notifications, and payment integration – fully tailored to your business. Intuitive admin panels to manage users, content, bookings, and payments – fully customizable.
