aconex GmbH needed to expand their HR management tool with a new customer satisfaction survey feature, something their clients urgently required. The system suffered from missing documentation, inconsistent code quality, and lacked a dedicated developer who could maintain, extend, and stabilize the platform. After difficulties with a previous developer, the client needed a reliable expert who could work independently and deliver fast.
aconex GmbH needed someone who could take full responsibility, stabilize the tool, and deliver new features without requiring constant oversight.
OTM introduced Edi, a full-stack engineer experienced in Java, Spring, Backbone.js, and end-to-end feature delivery. From day one, he took ownership of the product, cleaned up the technical foundation, and ensured predictable, fast results.
What impressed the client most was Edi’s independence and reliability. He translated business needs directly into solutions, with almost no meetings required.
Delivery
on-time delivery rate across all major features and releases, including complex HR automation modules
Performance
faster backend response times achieved through database and API optimizations for large datasets
Reliability
critical production issues over two years, thanks to stable code, clean migrations, and thorough validation
Continuity
years on the project, with multiple extensions
The client repeatedly extended the collaboration and proactively raised the hourly rate, because of the excellent results and dependable long-term support.
OTM made the entire collaboration effortless. From fast onboarding to ongoing support, I always felt backed by a team that communicates clearly and acts quickly. This allowed me to focus fully on development and deliver reliable results for the client.
