Supporting a major Latin American FinTech in it's Binance integration journey
Client Overview
A fast-scaling Brazilian fintech operating in the digital payments space had quickly become a key player in Latin America’s gaming and retail markets.
With Brazil at the heart of their operations, they offered instant payment methods like PIX and Boleto, enabling global companies to monetize in the region without local infrastructure.
As demand grew, so did complexity. The client was selected as the exclusive provider to facilitate transactions for one of the world’s largest cryptocurrency exchanges.
This wasn’t a coding task – it was about solving a business problem end to end. The client needed a system that worked under pressure, scaled with demand, and delivered a smooth experience from day one – and that’s exactly what we built.
Challenges Faced
To enable reliable crypto payments at a national scale, the client faced three main challenges:
Their existing infrastructure on Heroku couldn’t meet the performance and scaling requirements.
The integration with Binance had a tight deadline, with critical services dependent on timely delivery.
While internal teams had strong domain knowledge, they needed an experienced partner to lead the architecture and execution under pressure.
This project was more than a technical handover – it marked a strategic turning point for the company.
eLando’s Solution
We were brought in to lead the delivery of a three-phase strategy designed to unlock performance and scalability. Across all phases, eLando provided technical leadership, architectural planning, engineering capacity, and delivery oversight.
Phase 1 – Enabling Instant Payments via PIX
We implemented direct payments through PIX, allowing users to transact instantly with major Brazilian banks. This eliminated intermediary dependencies and significantly improved transaction speed and reliability.Phase 2 – Migrating Infrastructure to Google Cloud Platform
To future-proof the system, we migrated backend infrastructure from Heroku to Google Cloud Platform. This change introduced automated scaling, improved reliability under heavy load, and tighter control over deployment and monitoring.Phase 3 – Developing a Cryptocurrency Wallet
We developed a fully functional cryptocurrency wallet to handle payments, balances, and crypto trades. The wallet features an intuitive user interface designed for both novice and experienced traders, and it was engineered with scalability and reliability in mind.
Results & Impact
This project established the client as Binance’s exclusive transaction facilitator in Brazil. The platform now handles high transaction volumes smoothly and scales with demand.
System performance improved, reducing support requests and boosting user satisfaction. The cryptocurrency wallet offered users a seamless way to manage crypto and fiat assets.
These changes elevated the client from a basic payment processor to a trusted, full-featured payments platform. Following this transformation, the client successfully obtained a license to operate as a financial institution, further solidifying its market position.
Conclusion
This case shows how strategic execution and technical expertise drive growth in emerging markets. eLando provided a scalable foundation that let the client expand confidently and maintain control.
By building a robust, adaptable platform, we helped transform the client from a payments provider into a trusted gateway within one of the world’s largest crypto ecosystems – positioning them for ongoing success.
