JUSTEVERYWHEREFLOW. BUILD. SCALE.

Conversion websites, applications and internal systems

We build conversion-focused websites and applications that grow with your business.

We design the flow from the first visit to an order, booking, payment or submitted form. We build the design system, architecture, API contracts, tests and delivery foundation so future development does not turn into a fragile patchwork.

What we build

Five types of systems we build most often.

We approach each block as a product: user flow, operating logic, architecture, and room for further growth.

01

Order and e-commerce systems

For brands and operations that need to connect offer, cart, payment, and business logic into one flow, including integrations with invoicing, POS, delivery, and other external systems.

02

Reservation systems

For services and teams that need schedules, capacities, confirmations, changes, and dependencies without manual chaos, including an AI assistant for WhatsApp and Telegram, availability handling, and safe integration with a calendar, Alteg/Altegio, or another reservation system.

03

Templating systems for documents and reports

One of our main differentiators. We build systems that generate documents, messages, and reports with rules, versioning, and control.

What the client gets

Less manual work, fewer errors, and faster delivery of outputs with clear rules, traceable history, and a safe operating model that can scale further.

What the system can do
Manage templates without code changes
Variables and connections to internal data
Validation of required fields and content rules
Previews before sending or export
PDF / email / SMS / XML / additional outputs
Versioning and change history
Approvals and multiple responsibility levels
Roles and permissions
Audit trail
Accessibility and consistent outputs
Internal system integrations
04

Internal portals and admin systems

For companies that need clear internal tools and administration over data, roles, and workflow.

05

Website presentations

For companies that need a fast, trustworthy, and well-structured presentation of their brand, services, or product without unnecessary complexity.

What you gain

The outcome is not just a launched website, but a product ready for operations and further growth.

We treat conversion flow, technical foundation, design system, future development, and handover readiness as one system. That is what determines whether the product holds up after launch.

01

Higher conversion and more bookings

We design the user flow from the first visit all the way to an order, booking, payment or submitted form. We cover structure, CTAs, forms, speed, mobile usability, analytics, and room for A/B testing.

02

A robust technical foundation

Architecture, components, API contracts, tests, CI/CD, and monitoring are part of the design from day one. That keeps the product from turning into a fragile compromise after launch.

03

A shared design system

The UI is not based on one-off screenshots, but on a living component library in Storybook. Clients and teams can review states, variants, and key decisions in one place.

04

Safer and lower-cost future development

A new branch, reservation type, product, document, user role, or integration should not mean rewriting the system. We build it so the next iteration is neither expensive nor risky.

05

Lower vendor lock-in and better handover

We document decisions, components, APIs, deployment, and operations. That makes it easier for an internal team or another partner to continue without unnecessary rewrites or hidden dependency on one vendor.

After launch, everything must not slow down

We build so the next iteration is not expensive or risky.

A new branch, reservation type, product, user role or integration should not mean rewriting half the system. That is why we shape the architecture, components and operations so the product can keep evolving safely.

What we keep from the start

Shared components, API contracts, tests, CI/CD, monitoring and documentation are not extras. They are part of the design.

Technology we build on

From frontend and backend to data, AI, and infrastructure, we shape the full technical stack.

We do not treat technology as a badge catalog, but as a toolkit for a specific product. We have hands-on experience with modern web stacks, design systems, backend services, document workflows, cloud, DevOps, and more specialized integration and media systems.

01

Frontend, UI, and microfrontends

We build websites and client applications from a React/Next stack through the Vue ecosystem to design systems and modular frontend architecture.

02

Backend, APIs, and application logic

We design the backend layer from classic REST and GraphQL APIs to CMS, integration, and workflow services.

Cloud, infrastructure, and delivery

We deploy solutions from the application layer down to servers, containers, networking, and automated delivery workflows.

Quality, testing, and observability

We approach quality through tests, linting, review workflow, monitoring, and production diagnostics.

AI, media, and specialized systems

Beyond the standard web stack, we also handle specialized workflows for AI, broadcast, hardware, and distribution systems.

Technical guarantors

We personally oversee the key technical areas from start to finish.

JUSTEVERYWHERE is built on two complementary technical profiles. Pavel leads frontend architecture, design systems, standards, and technical leadership. Jan designs the backend, integrations, infrastructure, and operational reliability, including document and data workflows. We make the key technical decisions together and stay closely involved in the important parts of the solution throughout the project.

Pavel Vladimír Trávníček

Frontend architecture, design systems, and technical leadership

Pavel Vladimír Trávníček

Designs frontend architecture and component libraries across a React/Vue/TypeScript stack. He can take over and stabilize active projects, set conventions, quality gates, Storybook, and development workflow so the team can keep evolving the product safely. Alongside hands-on delivery, he brings mentoring, architectural consistency, and a strong feel for connecting technology with UX.

Backend architecture, integrations, and infrastructure operations

Jan Prochazka

Designs the backend and integration layer, database solutions, and operating infrastructure. He brings a strong overlap into DevOps, servers, Docker/Kubernetes, CI/CD, and deployment automation. He also leads more complex systems for document templating, WYSIWYG editors, data transformations, and external service integrations so the solution stays reliable both in the app and in production.
