Partner
A large-scale financial company in Central Europe, providing services to individuals and businesses for over 20 years, with more than 50 branches nationwide. Its in-house team had built the original fintech platform, but as the bank's partner network grew, scaling the product to match demand called for expertise and capacity beyond what the team held in-house.
Partner’s challenges
- A software scaling project that outpaced the in-house team's capacity mid-development.
- A need for front-end and back-end engineers specifically versed in fintech software development.
- Outdated payment systems and app logic that had to be modernized without disrupting live banking operations.
- The platform had to be adjusted to new business processes as the bank's partner network expanded.
Process of selecting required IT-specialists
Specialist selection
(3 days)
Senior front-end and back-end engineers with 5+ years of fintech development experience, matched against the bank's specific stack and scaling goals.
Candidate review
(2 days)
Screening of technical skill, domain expertise, and English proficiency; candidates move forward only with the approval of Modsen CTO.
In-house testing
(1 day)
Assessment of coding skill, problem-solving, and command of the project's frameworks — part of Modsen's continuous training and upskilling system, so requested engineers are ready to contribute on day one.
Technical interview
(1 day)
Evaluation of each candidate's fintech track record and problem-solving approach against real project scenarios.
Onboarding
(1 week)
Selected specialists integrated into the scaling project with full access to goals, timelines, tools, and resources. The partner saw no need for additional testing, though that option stays open for partners who want to verify specific skills.
