Johann Duscher

Continued in role following the transition of Bosch Security and Safety Systems to Keenfinity Group.

* Designed and implemented a Protobuf-based streaming protocol for AI-generated video metadata * Architected and developed distributed backend services using DDD, Event Sourcing, and Akka.NET * Combined architectural ownership with hands-on development, code reviews, and technical coaching * Introduced ADRs to improve architectural transparency and long-term maintainability

* Designed and implemented a fault-tolerant and resilient multi-node distributed Resource Management backend service based on Lightbend's Akka Framework for Java. * Implemented massdata stream recording and replay in Java 10 based on Reactive Streams (Spring Flux) and Apache Kafka distributed streaming platform. * Designed and implemented a framework for high-performance parallel reactive stream processing in C++ (similar to Rx.NET or RxJava).

* Implemented distributed receiver driver components in C++ (Qt). * Implemented GUIs for remotely controlled receivers visualizing/analyzing status information and mass data in C++ (Qt). * Greatly improved code quality by massive refactorings of large C++ code bases. * Designed and implemented a distributed multi-agent system framework in C++ (Qt, ZeroMQ, Protobuf, Google Test). * Designed and implemented agents for a high performance information processing system.

* Designed and implemented a firmware prototype in C / C++ for a mobile embedded system (Sierra Wireless Open AT, WMP 100). * Designed and implemented an emergency call system for the desktop (Windows, MacOSX, Linux) in C++ (Qt, BOOST, POCO, ZeroMQ) which also allows for configuring mobile alarm devices, handling incidents, visualizing tracks on a map, aggregating sensor data, and sending or receiving SMS messages.

* Application Design and Development. * Designed, refactored, and implemented a service oriented architecture based on .NET 3.5 WCF, Spring.NET, and BizTalk Server 2006. * Defined and standardized web service interfaces. * Designed and developed an OSGi 4.1 based application using Spring and Springsource DM Server. * Implemented model transformations and code generators in C# based on Sparx Systems Enterprise Architect UML models. * Intershop Enfinity development.

* Decision Support and Decision Making for Autonomous Systems. * Managed and coordinated software development projects. * Used formal specification and model checking techniques. * Used middleware based on CORBA and FIPA. * Ontological knowledge representation by means of Protégé. * Used rule-/logic-based programming languages, such as CLIPS, LISP, and ECLiPSe Prolog. * Developed a new concept for distributed decision support in the field of modular integrated avionics.

* Co-designed, redesigned, and implemented distributed software agents and parts of their communication protocol for the distributed internet application called Medienbroker. * Developed and implemented an algorithm for fuzzy search within a database for the purpose of rights document retrieval, which is successfully used within the Medienbroker project. * Designed and implemented applications for the Multimedia Home Platform (MHP) standard used for Digital Video Broadcasting (DVB).

* Further developed and improved a complex database that supports medical diagnosis and keeps track of a patient’s medications and anamnesis. * Designed and implemented a graphical user interface front-end for that database.

* Designed and implemented distributed internet applications. * Coupled software tools with existing relational databases. * Programmed software tools for coupling of standard tools that layout and optimize machines.

* Introduced the use of and created electronically forms, which improved and accelerated overall daily work significantly. * Coached / consulted colleagues concerning software- and hardware-related issues.
