Overview
Flyfish approached us with a visionary concept: to build a unified finance marketplace that consolidates services from multiple financial providers into a single platform. Their mission was to simplify business banking and payments and give users complete control of their financial world through an integrated fintech experience – think corporate IBANs, multi‑currency accounts, cards, wallets, payroll, crypto, and global payouts in one place.
The challenge was significant: build a secure, compliant platform that could integrate with multiple financial institutions while providing a seamless user experience. Additionally, the platform needed to serve both underbanked populations and sophisticated business users requiring multi‑currency accounts and international payment capabilities, with one‑time KYB/KYC onboarding.
Our role was to spearhead the front‑end architecture for this innovative fintech platform, build and manage a team of engineers, and collaborate closely with the CTO, QA, and product teams to navigate the complex regulatory landscape of financial services.

Technical Challenges & Solutions
Building an Integrated Financial Platform
The core of Flyfish's offering is its consolidated dashboard that gives users access to multiple financial services from different providers. We architected a front‑end solution that could seamlessly integrate with various banking APIs while maintaining a consistent user experience.
Our team implemented a modular architecture that allowed for easy addition of new financial service providers without disrupting the existing system. This approach enabled Flyfish to continuously expand their marketplace offerings while maintaining platform stability.
Navigating Regulatory Compliance
Financial services are heavily regulated, with requirements varying across jurisdictions. We worked closely with Flyfish's compliance team to implement robust KYC (Know Your Customer) and AML (Anti‑Money Laundering) processes directly into the user flow.
The platform needed to balance security requirements with user experience. We designed intuitive verification processes that satisfied regulatory requirements while minimizing friction for users during onboarding.
Multi‑currency Support and Global Payments
A key feature of the Flyfish platform is its ability to handle multiple currencies and facilitate global payments. We implemented a sophisticated currency management system that allows users to hold, exchange, and transact in various currencies.
The system integrates with SEPA, SWIFT, and SEPA Instant payment networks, making international payments as simple as local ones. Our front‑end implementation provides real‑time exchange rate information and transparent fee structures to help users make informed decisions.
Team Building and Leadership
Beyond technical implementation, we built and managed a team of 6 engineers dedicated to the Flyfish project. This involved establishing development workflows, code review processes, and quality assurance protocols to ensure consistent delivery of high‑quality code.
Regular collaboration with Flyfish's CTO and product teams ensured alignment between technical implementation and business objectives. We established agile methodologies that allowed for rapid iteration while maintaining the high security standards essential for financial applications.
