Web application development
Custom web application development, built to last
We design and build custom web applications, internal systems, client portals, dashboards and B2B platforms, end to end, from architecture to deployment, and we keep supporting them after launch.
A web application is more than a website. It has accounts and roles, real data behind it, business logic, integrations and a database that has to stay correct under load. That's the kind of software we build, not brochure sites or templates.
We designed, built and run a B2B web platform of our own, PersonalneAgentury.sk, so we know what it takes to keep one in production, not just ship it and walk away.
What we build
Internal business systems
Tools that run your operations, registries, scheduling, reporting, replacing spreadsheets and manual paperwork with one place your team actually uses.
Client & partner portals
Secure portals where your customers or partners log in, see their data and self-serve, cutting the back-and-forth on your side.
B2B platforms & SaaS
Multi-user platforms with roles, billing-ready architecture and the integrations a real product needs.
Dashboards & data tools
Operational dashboards that turn your data into something the team can act on, trends, metrics, exports.
How a project runs
Listen & scope
We start from your plan and goals, map the requirements, and give you a fixed quote, so you know the number before we start.
Prototype
We build a working prototype of the core flows. You sign off on the direction and the details before we build the real thing.
Build & ship
Architecture, database, frontend and backend, integrations, shipped to production properly, not left as a prototype.
Support & evolve
After launch we fix, update and keep improving it. We respect NDAs and stay reachable.
Built with
Security is built in, not bolted on: protected access and roles, sensitive data encrypted, and GDPR handled properly for EU users.
Proof, not a pitch
PersonalneAgentury.sk is a custom B2B web platform we designed, built and run ourselves, agency profiles, a bulk-inquiry system, smart filtering and convenient licence checks. Live in Slovakia.
Read the case studyCommon questions
What's the difference between a website and a web application?
A website mostly presents information. A web application has logins, roles, real data, business logic and integrations, software people use to get work done. That's what we build.
How long does a web application take?
Most first versions take a few months (often 3 to 9), depending on scope. You get a realistic timeline after the first conversation.
Can you take over an existing web app?
Yes. We've taken over and modernized plenty of unfamiliar codebases. Tell us what you've got.
Do you work with clients outside the Czech Republic?
Yes, remotely, and your product can target any market. Being EU-based means we handle GDPR cleanly when it applies.
