From Scratch to Card Swipe — How a lean team supercharged FSSTech global expansion?

Problem Statement

FSSTech aimed to expand globally by developing a tailored suite of payment solutions for small and medium-sized businesses (SMEs). Their goal was to emerge as a strong competitor to established market leaders such as Stripe, thereby repositioning themselves in the industry.

Client Info

FSSTech, an Indian fintech company, specializes in payments solutions, including ATM services and digital banking, with an estimated revenue of $200 million

Outcomes

Launched a PCI DSS Level 1 Certified Application

Handles 5000 transactions per second

Facilitated entry into North America & Europe markets

How did BeautifulCode do it?

The collaboration kicked off with a two-week domain immersion session, integrating FSSTech's payments expertise and BeautifulCode's software development insights. This was complemented by implementing the Remote Engineering Framework (REF) onboarding process, streamlining alignment for remote engineering teams.

Timeline chart — Timeline of product and development sprints

Managing Product, Development and Launch velocity

To adapt to the dynamic nature of business changes, BeautifulCode introduced a separate "Product Sprint" which runs in parallel to the development sprint. The core participants in these sprints included Product Managers and the Engineering Lead. The primary objectives of the Product Sprint are as follows:

Evaluate and discuss the technical viability of suggested product features
Deconstruct product requirements into manageable and iterative features
Handle potential obstacles for the upcoming development sprint which involved activities such as understanding API documentation, exploring third-party solutions, conducting proof of concept (POC), etc.

Conclusion

BeautifulCode built a competitive white-labeled, PCI Compliant, cloud native solution with features on par with the industry leaders like Stripe. The product served different personas such as Merchants, SubMerchants, Independent Software Vendors and Payment Facilitators. Upon project completion, all accumulated knowledge, training, and the entirety of the code base were successfully transferred to the internal teams at FSSTech.
