ChrumIT is a web and mobile development team based in Białystok, Poland. The company works with modern web technologies including JavaScript, TypeScript, Angular, Ionic, PHP, and NativeScript. Their portfolio spans web applications built with CMS platforms (Grav, Joomla, WordPress) and Bootstrap, as well as native and cross-platform mobile apps. The team actively participates in local JavaScript meetups in Białystok and has contributed as both participants and instructors to postgraduate front-end developer programs in the region.

Services and capabilities

ChrumIT offers three main service categories. They build websites using CMS platforms (Grav, Joomla) and Bootstrap, targeting clients who need either straightforward content management or custom builds. Their applications work spans PHP backends paired with Angular, Ionic, or NativeScript frontends. The company also provides technical consulting for both frontend and backend work, positioning themselves as a resource for projects stuck mid-development.

Mobile development appears to be a significant focus. Their portfolio shows multiple Ionic and Angular projects, including Attendance List (a scheduling and attendance-tracking app for training sessions), Trayvo (a trainer-management and class-booking platform), and TeamItUp (described internally as "Facebook for athletes," with features like stat-based photo generation and competition result tracking). The team has built apps with both Ionic 2 and Angular 2, as well as NativeScript.

They also handle graphic design and web design work alongside development, though specifics on those services are limited.

Notable work

ChrumIT's portfolio includes at least nine completed projects. Attendance List automates what was previously a paper-based process for recording class attendance, solving a compliance need created by new regulations. Trayvo lets trainers create and manage training sessions, bookings (virtual, group, individual, one-time, or recurring), while clients book from available options. TeamItUp, built for a foreign client, is a social network for athletes that generates statistics-based images, tracks competition results, and includes other custom features beyond basic social posting.

Other projects include Maltrans (Bootstrap, jQuery, HTML5, CSS3), isoScale (Java), EcoFlashlight (Ionic 2, Angular 2), Husarz Białystok (Joomla CMS site), SMD (WordPress), and HomeQ Mobile (Ionic 2, Angular 2, TypeScript). The company notes they've completed dozens of projects but cannot publicly disclose all of them due to NDAs.
