Catering for Internal Needs

An industry-leading EPOS technology provider had a capable development team. Their roadmap was chock-a-block with features catering to end clients’ needs. However, the CTO and his in-house team faced constant pressure from the marketing, operations, and sales departments, each demanding changes to be rolled out in the shortest time possible. Realising that this was akin chasing one’s tail, the CTO decided to enlist an external team to handle the delivery of functionality less critical but vital for the business.

SPG was awarded this opportunity. The company’s specialists created a web-based sales analytics and reporting subsystem, and integrated it into the customer’s wider suite of admin tools. They also helped adopt the SPA approach, introducing a variety of modern technologies such as React and Redux (which accelerated the development of dynamic and responsive interfaces). The SPG team then designed and implemented another separate forecasting subsystem that utilised a number of data science and machine learning capabilities.

Upgrading the Legacy Codebase

A SaaS platform for UI and product designers approached SPG. The solution allowed its users to design, collaborate on, and present visual concepts — from low-fidelity wireframes to fully interactive prototypes. While the existing team worked around the clock implementing new features, the company’s CTO grew increasingly concerned about the accruing technical debt, and the numerous postponed migrations, which were increasingly time pressing.

The SPG team was tasked with analysing how a legacy API microservice written in PHP could be re-implemented with Node.js and Ruby, as required by the new architecture approach to the APIs. The Node.js part had to cover all functionality related to working with mockups and wireframes, while Ruby-based code had to incorporate user management and payments functionality. The SPG specialists helped uncover some long-forgotten dependencies and complexities in the architecture. In addition, they facilitated the platform’s update to the most recent versions of Node.js and other frameworks. This successful upgrade and unification of the versions made the product team’s life easier, as they could continue development and maintenance using the latest versions of the software available.

Diverse Expertise Helps Beat Old Performance Problems

Our customer was running a web-based solution offering numerous cybersecurity analytics tools to business customers and individuals. The platform’s key features included:

• A cyber security score based on the analysis of digital behaviour
• A tailored action plan
• Scanning for Cloud infrastructure vulnerabilities
• Data breach monitoring

SPG was offered the opportunity to augment our customer’s in-house team. The relationship began by developing a set of brand-new microservices for a phishing simulator. Each microservice had to follow the Domain Driven Design (DDD) approach. Given the platform’s evolution over a long period, its ecosystem was an array of various technologies and frameworks. After successfully releasing new functionality, the SPG specialists were invited to address an old problem with memory leaks — one of the SaaS processes regularly stalled. The problem was rooted in outdated architecture and limitations of the underlying technology. The SPG team suggested porting this legacy logic to Kotlin and Quarkus (quarkus.io). As a result, long-lasting performance issues were eliminated entirely. Problems with traceability and debugging also improved.
