Cross-border payments engine for a B2B fintech

The company, an established company inFinTech headquartered in Spain, needed to solve this challenge: “cross-borderpayments engine for a B2B fintech”. The obstacle wasn't so much business domainknowledge —always valuable— as finding profiles with demonstrable experience inthe project's specific technology stack; in fact, they had already tried hiringfor it without success, with the added expense and lost opportunity thatentailed. All of this was happening under time pressure, with a market deadlinethat left no room for error.

Squad Challenge designed severalchallenges to evaluate the profiles that different outsourcing firms presentedto the client. The challenges were built around the business case itself andits technology stack, evaluating more than 30 professionals in 14 days.

The initial squad was made up of 6 profiles (frontenddeveloper, Tech Lead, backend developer, DevOps/SRE, full-stack developer, MLengineer) working on a stack of PostgreSQL, AWS, Kafka, and Python (FastAPI),sourced from the outsourcing firms evaluated. This squad integrated with thecompany's existing in-house technical team, respecting established processesand priorities. The team's high turnover required evaluating 10 additionalprofessionals over the following 12 months, for a total commitment of 19 months.
