Web Design & Development — business sites, stores, and landing pages built for hard sales
We design and build business sites, online stores, and landing pages optimized for conversion. We match the stack to the project — from ultra-lightweight builds on React, TypeScript, Tailwind CSS, and Supabase, to WordPress for content-driven projects. AI speeds up the engineering and cuts design time, with experienced developers overseeing the whole thing.

A business website isn't a digital business card. It's your primary sales channel.
Forget slow, poorly coded sites that keep generating technical problems. Our web design and development process means unique functional layouts that lead the user to a goal — contact, form submission, or completing a purchase. We don't force a single solution. For projects that demand serious speed and rich functionality, we build component-based code on React and TypeScript paired with the Supabase cloud. For sites focused on heavy content marketing and extensive blogging, we deploy an optimized WordPress setup, and for advanced online stores, we configure Shopify or WooCommerce. AI tools cut prototyping time in half, but every piece of the structure is reviewed by an engineer — we don't publish a project without meticulous human oversight.
4 reasons your business website is losing customers
Technical and design problems we systematically eliminate in our day-to-day agency work.
An overloaded structure with no path to conversion
Many sites are designed as works of art, forgetting about user behavior psychology. Information overload and hidden contact details mean customers leave the site without taking the action you wanted.
Critically slow load times on mobile devices
Heavy, unoptimized code and server misconfiguration drastically extend load time on phones. Users give up waiting, resulting in immediate loss of traffic you're already paying for in ad campaigns.
No basic analytics — a blind start to marketing
Launching a site without tracking codes, a tag management system, or search engine integration cripples every promotional effort that follows. Running campaigns on an unprepared site makes accurately measuring ROI impossible.
Total dependence on developers for every minor change
Sites built with overly complex architecture block your marketing team's flexibility. Having to pay outside specialists to add a simple article or change a price creates unnecessary fixed costs and slows down business processes.

Frequently Asked Questions
What defines a modern tech stack built on React and Supabase?+
This is an engineering approach used in building web applications. Instead of building a site on heavy templating systems, we write clean, component-based code (React + TypeScript). Data and backend functions (like forms or user accounts) are handled by the Supabase cloud platform. This delivers millisecond page loads, strong protection against attacks, and no need for ongoing plugin maintenance.
When should I choose WordPress, versus a component-based architecture (React)?+
WordPress is the optimal choice for business sites focused on heavy content marketing, running a large blog, and for teams already comfortable with this editing interface. We deploy component-based architecture (React + Supabase) for projects that demand top-tier code performance, strong data security, and custom application functionality, where load speed is the priority.
Shopify or WooCommerce — which is the better choice for my store?+
Shopify is an excellent choice if you want strong stability, security, and no need for ongoing development maintenance. WooCommerce, built on WordPress, is ideal for e-commerce that needs product flexibility, deep blog integration, and no platform commission fees — we most often recommend it for brands wanting more control over their code and data.
How much does a website cost, and how long does it take?+
Prices start at $500 for a landing page or a simple business site. Delivery typically takes up to a week, depending on resource availability (content, graphics, system access).
