Rebased

Rebased was a Polish software development shop based in Warsaw, with additional offices in Sopot and Koronowo. The company is no longer accepting new work—in 2024, the Rebased team joined Shopify and shut down its agency operations. What remains worth understanding is what Rebased actually did: they were a Ruby-focused outfit that built web applications for e-commerce, enterprise software, and startups. The team consisted of developers with serious depth in Rails, having worked on projects ranging from large e-commerce integrations with ERP systems to conference management platforms and construction site software. Many team members had been professional Rubyists for a decade or more, with side interests in functional programming languages, DevOps tooling, and full-stack development.

Services and capabilities

Rebased worked primarily on web application development using Ruby on Rails. Their project list included an e-commerce platform integrated with external ERP systems, an enterprise SEO analytics provider processing gigabytes of data daily, a high-profile conference site with backoffice integration to CRM and ticketing systems, construction site management software with issue tracking and blueprint integration, and a loyalty program backend for a gas station network. The team also built internal analytics tools for HR and sales use.

They favored Rails for administration backends and used testing frameworks like Minitest. The stack included Pact for contract testing in distributed systems, RuboCop for code analysis, and tools like Tolk for i18n translations and Trix for WYSIWYG editing in Rails apps. On the infrastructure side, they worked with Ansible and Docker for DevOps. Beyond Ruby, they touched JavaScript (Ember.js, React), Rust, Python, and Clojure depending on project needs.

Notable work

Projected mentioned in their portfolio included a large e-commerce site with external ERP integration, an enterprise SEO analytics platform handling gigabytes of daily data, a high-profile conference system with CRM and ticketing integration, construction site management with blueprints and notifications, and a loyalty program backend for a gas station network. They also built company resource analytics tools for both internal HR and external sales teams.

How they work

Rebased operated out of three Polish cities: Warsaw (headquarters at ul. Bohomolca 15), Sopot, and Koronowo. The company was active in the local developer community, sponsoring and supporting the Warsaw Ruby Users Group (founded in 2008 by Rebased founders), Rails Girls initiatives across Poland, and several regional Ruby meetups (WRUG, KRUG, TRUG, SRUG). Team members spoke at conferences like EuRuKo 2017 and PolyConf 2017.

Team and credentials

The team included developers with a decade or more of professional experience in Ruby, starting from 2005 in some cases. Backgrounds spanned information retrieval systems, concurrent programming, DevOps (Ansible, Docker), Android development, and distributed architectures. One founder was the organizer of Warsaw Ruby Users Group since 2008. Another was an assistant professor at Warsaw University of Technology. The company was formally registered as Rebased sp. z o.o. with VAT-ID PL1182098300. As of 2024, Rebased is no longer operating as an independent agency.
