The Challenge

Racing Against a Regulatory Deadline

The Situation

A major European bank with operations across 4 countries was facing a critical PSD2 (Payment Services Directive 2) compliance deadline. Their existing team of 8 developers was insufficient to deliver the required open banking APIs, security modules, and third-party integrations within the 6-month regulatory window.

Key Constraints

  • 6-month hard deadline — regulatory penalty risk of EUR 2M+
  • Need for Java/Spring Boot expertise with banking domain knowledge
  • Strict security clearance and compliance requirements
  • Local hiring impossible within the timeframe (4-month average in fintech)
  • Budget constraints vs. Western European contractor rates
The Solution

17 Specialists in Three Strategic Waves

Team Composition

10 Java Developers Spring Boot, microservices, PSD2 APIs
3 QA Engineers Automated testing, Selenium, security testing
2 DevOps Engineers CI/CD, Docker, Kubernetes, AWS
2 Business Analysts Banking domain, PSD2 requirements, API specs

Our Approach

Rather than flooding the client with all 17 people at once, we deployed specialists in three carefully planned waves. This allowed the existing team to absorb new members effectively, maintain code quality, and keep the project moving while onboarding continued. Each wave was preceded by thorough technical interviews and client approval — we presented 3 candidates for every 1 position, ensuring the best match.

The Results

Deadline Met, Budget Saved

100% PSD2 Deadline Met

40% Cost Savings

95% Team Retention

Only 1 of 17 specialists left during the project (personal reasons), replaced within 3 business days.

2-4 weeks Time to Productivity

Each specialist was contributing production code within 2-4 weeks of onboarding.

They delivered 17 specialists who integrated seamlessly — most were productive within the first two weeks. The cost savings compared to local hiring were substantial, but more importantly, they met the deadline. That's what mattered."
