Custom Website & Web App Development — UX, SEO, PWA
Who do we build websites and apps for?
We create websites that help attract clients, build trust, and automate sales. This includes corporate sites, one-pagers, or web showcases — tailored to the goals of your niche, whether it’s services, manufacturing, or retail.
Our team helps bring products to market fast: we develop MVPs — minimum viable versions of web apps that let you test hypotheses and attract your first users without wasting time or budget.
We design scalable architectures that can handle high loads and support complex business logic. PWA support, mobile optimization, and fast load times are essential components of every solution.
We take on projects as an outsourced team or white-label partner. We work within your tech specs or handle full-cycle development from scratch. Strong front-end, solid back-end, stable APIs — we ensure code quality and on-time delivery.
What’s included in website or web app development?
Our process is clear: you always know what’s happening at every stage. We stick to timelines and follow the agreed schedule
Fast loading, clean code, SEO structure & microdata
We follow high technical standards: optimize loading speed, write clean valid code, use logical URL/tag structure, and implement Schema.org markup for better indexing
High-load support & API integrations
We build reliable server-side solutions with scaling capabilities, horizontal growth, and third-party service integration via REST or GraphQL APIs. Especially critical for web apps and platforms with active user bases. PostgreSQL, MongoDB — robust storage and fast data processing
UX focused on behavior & conversions
Every solution is built around real user behaviour. We design interfaces that lead users to target actions: submitting a form, making a purchase, or signing up. This improves conversions and shortens the customer journey.
What types of websites and apps do we build?
We create showcase websites for brands, companies, and services with clear positioning and SEO readiness – from simple landing pages to full multi-page solutions
We deliver eCommerce solutions with filters, shopping cart, checkout, user accounts, and CRM integrations – focused on usability, speed, and reliability.

Interfaces and systems for working with corporate clients: personal accounts, reporting, order management, and data control. High security and usability are key
Platforms for learning, admin tasks, and internal operations – from testing and tracking to task distribution and communication. Often implemented with a flexible role-based access model
