Web applications

Reservation systems, management systems, CRMs, ERPs, marketplaces and dedicated tools – we build web applications that solve complex business problems. With API integrations, multi-user logic, automations and scale-ready architecture. From MVP to enterprise solutions.

Our Approach

What sets our web applications apart?

  • Designing from the business process

    We don’t start with code. We start with process mapping, user roles and data flow. We understand how your business works and design a system that supports it at every level – from day-to-day operations to strategic decisions.
  • Scale-ready architecture

    We build with the future in mind. Modular architecture, API-first approach, microservices where they make sense. A system that supports 100 users today will easily handle 10,000 tomorrow. Scale without rewriting from scratch.
  • Integrations that really work

    We connect your system to what you already use: CRMs (Comarch, HubSpot, Salesforce), ERPs, Baselinker, payments, mailing, accounting systems, external APIs. We automate data flow, eliminate manual work and reduce errors.
Our Capabilities

What do you get along with the web application?

Multi-user system with roles

Precise access control: administrators, managers, operators, customers – everyone can see and edit only what they should. Permission system, audit log, change history. Data security and process transparency.

Dashboard and analytics

All key metrics in one place. Real-time process monitoring, custom reports, exports to Excel/PDF, data visualizations. Make decisions based on facts, not guesses. API for external analytical tools.

Integrations with external systems

Baselinker, CRMs (Comarch, HubSpot, Salesforce), accounting systems (InFakt, Wfirma), payments (Stripe, PayU, subscriptions), mailing (MailerLite, Mailchimp), calendars, messaging. Two-way data synchronization, webhooks, REST API.

Automations and workflows

Automatic task assignment, email/SMS notifications, escalations, reminders, document generation, multi-level approvals. Workflow tailored to your processes. Less manual work, more control.

REST API and documentation

Full API to integrate your system with any external tools. Technical documentation, usage examples, sandbox for testing. Openness to integrations that are yet to be needed in the future.

Hosting and infrastructure

Scalable cloud infrastructure (AWS, Google Cloud, Azure), automatic backups, 24/7 monitoring, SSL certificates, CDN. High availability, security and performance. We can host in-house or at your location.
Our Process

What does our process look like?

Process Mapping & Discovery

We map your current processes: who does what, where are the bottlenecks, which operations can be automated. We define user roles, permissions, data flow and integrations with external systems. We design the system architecture and development roadmap.
01

Wireframes & User Flows

We design user flows for each role: the administrator sees the dashboard, the operator sees the task queue, the customer sees his orders. Wireframes of key screens, navigation system, forms. All with the efficiency of daily work in mind.
02

UI Design & Design System

We create an interface that is intuitive and functional. Consistent system design: components, tables, forms, notifications, modals. We take care of UX for power users – keyboard shortcuts, bulk actions, filters, search. Everything to make work faster and more pleasant.
03

Development & Integrations

We build backend, frontend, database, API, authorization, permission system. We implement all integrations with external systems. Unit testing, integration testing, code review. CI/CD pipeline – every change automatically tested and implemented.
04

UAT, Training & Launch

User Acceptance Testing with your team. Training for users of all roles. Preparation of user and technical documentation. Production deployment, data migration, monitoring. Post-launch: technical support and development in retainer model.
05
Tools are a must

What tools do we use on a daily basis?

Collaboration goes more smoothly when everything is organized and transparent – that’s why we work in tools that facilitate communication, planning and project execution. They give you a full view of the progress of the work, allow you to comment on projects in real time and participate in the process as you are comfortable.

Figma
We design the application interface in Figma, where you can comment on every screen, flow and interaction. Wireframes, prototypes, design system - all in one place with full transparency.
Google Meets
Regular status meetings, progress presentations, UAT sessions. No unnecessary formality, but with full commitment and concrete decisions. Recordings available after each meeting.
ClickUp
Manage project, sprints, tasks and priorities. You have full visibility into the backlog, current sprints, testing and finished functionality. Roadmap updated in real time.
Node.js / Python / PHP
We select the backend technology for the specifics of the project and existing infrastructure. Node.js for real-time, Python for data processing and AI, PHP for enterprise systems and legacy integrations.
PostgreSQL / MongoDB
Relational databases (PostgreSQL, MySQL) for structured data, NoSQL (MongoDB) for flexible schemas. Always with performance, scalability and data integrity in mind.
FAQ

Still have questions?

We know that choosing a technology partner is an important decision. We have prepared answers to key questions about cooperation, costs, lead times and technology. If you need more information, our team is at your service.
Depends on the complexity of the system. A simple reservation or CRM system is 10-16 weeks. More advanced projects with multiple integrations, complex business logic and an authorization system are 20-30 weeks. We always start with a discovery and process mapping workshop, where we jointly define the scope of the MVP and development roadmap.
Yes! We design applications with scalability and growth in mind. Modular architecture allows you to add new functionality without rewriting the entire system. REST API enables integrations with new tools. We document the code and provide full technical documentation.
Virtually all: CRMs (Comarch, HubSpot, Salesforce, Pipedrive), ERPs, Baselinker, accounting systems (InFakt, Wfirma, Comarch), payments (Stripe, PayU, subscriptions), mailing (MailerLite, Mailchimp, SendGrid), calendars (Google Calendar, Outlook), instant messaging (Slack, Teams), webhooks, custom REST APIs.
Security is the foundation. Data encryption (SSL/TLS, in-base encryption), secure authentication (OAuth2, JWT, 2FA), permission system, audit log of all operations, regular backups, security monitoring, RODO compliance. Penetration testing before production deployment.
Yes. We design the architecture with scaling in mind: caching (Redis), job queues, load balancing, CDN for static resources, optimizing database queries, microservices where they make sense. Monitoring performance 24/7 and responding to bottlenecks before they become a problem.
Yes! We can deploy the system on your infrastructure (on-premise), in your cloude (AWS/Azure/GCP) or at our place. We provide full deployment documentation, dockers, deployment scripts. We also offer managed hosting with 24/7 monitoring and support.
We provide training for all user roles: administrators (system management, permissions, reports), managers (dashboard, analytics, processes), operators (daily operations, forms, workflow). We also prepare user documentation, video tutorials and knowledge base.
A simple reservation or CRM system is an investment from 40 000 PLN net. Moderately advanced projects with integrations and complex logic are PLN 80,000 – 150,000 net. More complex enterprise systems (marketplace, ERP-like) start from 200 000 PLN net. We provide an exact quote after the discovery workshop.
