Braille & Audio Production

Dedicon is a non-for-profit that serves the visually impaired population of the Netherlands by making information readable, visible, audible or tangible. I really enjoyed working for Dedicon and contributing to their cause of helping our fellow impaired citizens.

As a lead dev, I was responsible for the technical design and implementation of the new production and reproduction orchestration, which processes over a million orders each year. My primary focus lay on the Broker; a sophisticated integration between the Cloud-based ERP-solution AFAS Profit and Dedicon’s own internal service landscape.

• Put Profit, the ERP-solution of AFAS, at the heart of the system, centralizing data there and minimizing alternate truths
• Capable of processing thousands of orders in a short period (burst-processing)
• Transaction-based, parallelized and idempotent processing of orders, maximizing throughput, minimizing fall-out, supporting recovery and disaster scenarios
• Design and implement a Canonical Data Model to ease reasoning by domain experts and standardize messaging exchange between applications
• Generate metrics and push telemetry to Dedicon’s operations monitoring system (Zabbix)
• Simple web-interface for operations to handle orders that failed to process
• Implementation using well-known industry proven technologies, like Java, Spring Boot, SQL Server, XML/XSD, etc.
• Set-up DTAP-environment, automated builds and deployments

I incorporated all the above requirements into a suitable implementation based on modern techniques and design principles.

As a tech lead, I provided guidance to the software development team of Dedicon (8 people), by introducing the Atlassian stack, automating builds, automating regression testing, introducing continuous integration and automating deployments.
