Eldorado Hub is a cryptocurrency exchange platform built for people in countries where traditional currencies lose value daily due to inflation.

The platform offers a secure and simple way to convert savings into stable, low-volatility currencies.

Our role was to quickly deliver the first version of the platform so the founders could validate their product hypothesis, test with real users, collect feedback, refine the solution, gain traction, and attract investors.

We achieved all of this in less than six months. After the handover, the client successfully continued developing the platform with their own team.

Business challenge

The goal was to build a user-friendly, fast, and secure P2P cryptocurrency exchange platform with a built-in reputation system.

We worked with the client from the initial idea through to the launch of the first version. The process began with our Product Discovery Workshop, where we defined high-level goals, must-have features, and non-functional requirements. From there, we created a roadmap of short, achievable milestones and moved quickly into execution.

The four main challenges were:

1. Managing the complexity of P2P cryptocurrency trading and integrations with multiple third-party providers
2. Setting up microservices efficiently while keeping infrastructure costs within the startup’s budget
3. Ensuring high security and scalability without exceeding reasonable development and infrastructure costs
4. Designing a platform that is easy to use and fast, even in regions with low internet bandwidth

Business solution

Our Product Manager and development team worked closely together to avoid wasting time on goals that didn’t add value.

The aim was to test the feasibility of the idea while keeping costs low without compromising quality or security. Our approach was straightforward: build a dedicated fintech solution quickly, gather client feedback as early as possible, and then improve the product.

We accelerated development by using third-party solutions, such as an anti–money laundering layer. Following domain-driven design best practices, we created secure and extensible microservices that could be adapted easily to new requirements.

To address infrastructure costs linked to microservices, we combined select SaaS providers with AWS pay-per-usage tools. This strategy kept expenses minimal while the platform was still gaining traction. For example, instead of hosting our own Jenkins Master and Slave architecture, we moved continuous integration to AWS CodeBuild, CodePipeline, and CodeDeploy, which resulted in significant cost savings.

Results

We delivered the first version of the platform, which played a crucial role in the product’s success. It gave the client momentum and helped secure funding for further development. Since then, their internal team has continued to grow the platform and raise additional financing rounds.

Today, El Dorado is thriving as an independent company, and we are proud to have supported the start of their journey.
