Client testimonials

PhD Johannes Fritz Project Manager at Global Trade Alert

The Code & Pepper team became involved in the process of designing the desired tool already at the bidding stage. Even though they didn’t have much time to answer our complex request for tenders, the effect was mind-blowing. They had had a very practical approach from the very beginning, and this is what made us select them.

Duncan Campbell Head of Product at Oathello

Code & Pepper provided an impressive level of service outside the original scope of requirements. At no additional charge, they proactively redesigned the product to enhance the final version. They took on the bulk of project management responsibilities and facilitated an open line of dialogue throughout.

Aurélien Bonnel CTO at TradeCrediTech (Nimbla)

Code & Pepper provides high-quality, reliable code and designs. Flexible, responsive, and dedicated to client satisfaction, working with their team continues to add a lot of value to the business overall.

How we work


Scrum is our go-to method for effective collaboration. For quick projects – up to 3 months – we may also switch to Kanban. In all projects, the team uses proven measurement techniques (i.e. scoping by story points, story points burndown per sprint) to determine the development velocity and plan reliably.


Before the team rolls up their sleeves to start coding, we need to establish and agree on product requirements. To understand the product inside out, we define the scope of the product, establish acceptance criteria, and prepare UI/UX design in the form of mockups and visuals.

Development process

The features of your application are thoroughly checked and analysed from all angles using top industry practices. These include: multiple types of tests, code review (developers check each others’ code for possible improvements), Continuous Integration/Continuous Development (new features are released to production as quickly as possible). Thanks to rich client base and resource re-allocation, you can scale or de-scale your team size according to current needs.


Thanks to the flexibility of development plans, we are able to support you with different technologies in optimal proportions – we can engage a team member part-time or full-time, depending on the demand. Code & Pepper developers are skilled in a vast number of technologies you can find above and on our Services page.

One team policy

From day one, you can expect total transparency on our side – every resource produced by Code & Pepper connected with product development will be shared with you, including code repository, team members’ timesheets, budget flow, risk logs, source graphic files, etc. Instead of conducting all communication via a single contact person, it is handled across everyone involved, both on the client’s and team’s side.
