Achieving growth without escalating costs

Since its creation, our Client has been committed to delivering the finest slots in the industry.

This effort demands continuous exploration of tech innovations to meet player demands and industry trends. While better technology yields better results, it can be costly. And we all know that staying within budget is key to sustainable growth.

The Client’s software required modernization and ongoing support. They aimed to refurbish their code and APIs. Develop a mobile app to reach new audiences. Give their players more payment options. Manage all of this while keeping costs in check.

To tackle these challenges, they decided to augment their in-house staff with top experts worldwide.

Since 2021, SENLA has worked on several key modules of the Client’s platform and developed the mobile application.

“We constantly strive to offer, without pause, a world-leading game portfolio and this is also how we choose which partners to work with – as only the best is good enough for our players.”

Our Client

Why SENLA?

⦿ SENLA’s strength lies in our broad tech expertise and how we nurture it. For this Client, we provided top experts for several areas of the product, all in one place and under a single contract.

⦿ As a mid-sized company, we offered a very competitive price-performance ratio with a steady commitment to the highest quality standards.

⦿ Based in Europe, our mindset and corporate culture closely aligned with the Client's, which made our collaboration effortless.

Microservices system for APIs

APIs are the heart and brain of an iGaming platform. It’s the hub that serves three purposes and connects three audiences:
⦿ Customers who play the games and make bets.
⦿ Game providers who host their games on the platform.
⦿ Payment providers who ensure secure and reliable money operations.

Think of it as a bustling highway during rush hour, where the entire business and profitability rely on its smooth operation and traffic flow.

But then imagine that this highway is two-lane only. Access to it is limited and complicated, and maintenance takes a lot of time and resources. That it cannot cope with the new traffic it needs to let through. That was the challenge our Client faced.

The old system was monolithic with all modules in one repository, limiting modifications. With time it became increasingly evident that such architecture hindered the platform’s growth and consumed significant maintenance resources. A need for a leaner solution arose.

SENLA joined the team tasked with segmenting the platform into separate microservices, like User API, Payments API, etc. that could be independently accessed and used for various purposes.

Using the Laravel PHP framework, our back-end experts transformed the old code to create APIs for internal and external partners. In parallel, the code was optimized and refactored. The challenge lay in rewriting while maintaining the old, heavily-used codebase operational 24/7.

“Being admitted to developing the APIs is a big honor and responsibility for SENLA. These are at the heart of the Client's business and require top security. We are proud to contribute our expertise to API development.”

Mobile application

Today, mobile apps are essential in competing for customer attention. After all, most people play casual games on their phones, right? The gaming industry has largely shifted to a mobile-first approach.

That’s especially true in North America, where our Client obtained its first license. To attract new users and boost revenue, the company decided to launch a mobile app. SENLA's mobile developers were brought on board for this project.

The app was intended to mirror the website entirely. It was developed using Flutter and Dart, with some modules in JavaScript. Flutter was chosen because it supports cross-platform application development—a preferred standard in North America. As a result, we optimized the development speed and costs.

Our developers examined the software specifications and UI mockups. Then they implemented the features and UI components into an MVP to align it with the existing website. In later stages, they worked on debugging and resolving issues.

The team collaborated closely with the API team, a necessity given the main platform's complexity. It stemmed from diverse jurisdictions, a multitude of payment methods, and the main product's functionality.

Payments

The payments module is the most responsible part of an iGaming platform. Smooth monetary transactions influence the whole business. Therefore, it's vital to offer players a variety of options and ensure effortless deposits and withdrawals.

“We work endlessly to improve our casino and website, to launch more games and suppliers, as well as increase the choice of payment methods for our players.”

Our Client

A separate team, which included SENLA's specialists, oversaw the payment aspect. They managed various payment methods such as bank accounts, credit cards, or Apple Pay, tailored financial modules to specific regions, and ensured thorough testing for all money procedures. Currently, they are integrating cryptocurrencies to open new markets to the Client and attract tech-oriented players.

Taking into account the heavy legal regulations in this sphere, a range of specific characteristics exist for payments:

  • Anti-money laundering. Each jurisdiction enforces specific deposit and cashout rules. For example, players must withdraw money using the same method they used to deposit. This prevents money laundering and fraud.
  • Responsible gaming. To combat gambling addiction and impulsive behavior, the platform allows players to set weekly or monthly deposit and loss limits. If players choose to modify or remove these limits, any changes will only be effective after a 7-day waiting period. This ensures enjoyable gaming that doesn't lead to financial or personal issues.

Test automation

iGaming platforms are complex and offer a wealth of features and games. They evolve quickly, need to be legally compliant, and must run reliably 24/7. One glitch can cost an operator millions in revenue.

That’s where test automation can save the day. Automated tests can cover and speedily execute a wide range of cases.

Our Client outsources QA automation to SENLA for several modules of the platform, such as registration, payments, and internal minigames.

Consider the signup and login process on the website. Each country where the casino operates has its unique registration procedure. All of them need to be verified and regulatory compliant. Besides, whenever our Client enters a new market or local laws shift, the process requires swift adjustments and thorough checks for all regions.

In addition to providing thorough testing, our specialists also mentor the Client's manual QA specialists, enhancing their skills in test automation. The aim is to nurture adaptable experts who can step into multiple roles and support one another.

“Adapting to numerous jurisdictions, each with its unique nuances, and managing a multitude of test environments makes our work on this project challenging but truly fascinating.”
