* Developed new OS-native Bricks build system bootstrapper with automatic update ability, achieved over 90% unit test coverage.
* Prepared and executed migration of the Bricks build system and corresponding repositories to a different GitHub server.
* Rewrote Bricks entity database synchronization component for improved code quality, performance, stability and test coverage (Golang / Google Go, Python, SQLite).
* Substantially contributed to Bricks build system release quality by developing Bricks build system system tests and downstream user project test jobs.
* Created additional technical documentation for the Bricks build system and the Bricks bootstrapper using the C4 model (c4model.com) and Sphinx.
* Recommended to use Sophist MASTeR templates for user requirements gathering for improved successor build system, organized and held meetings for capturing requirements of multiple core teams.
* Set up an AWS ElastiCache for Redis instance to be used as Bricks Evolution Build System build cache (AWS, HashiCorp Terraform).
* Set up an AWS Redis Cluster to be used as Bricks Evolution Build System build cache (AWS, CloudFormation).

Technnical landscape: multiple thousand ATM devices over Austria and Hungary as well as central servers they communicate with

* Designed and implemented numerous banking features such as: savings book operations (deposit, withdrawal, transfer), money dotation and withdrawal for various cash devices, employee mode and maintenance mode functionalities, surcharge (Kostenersatz Bargeld) and top user transaction features, multi-type money transfers (payment, donation, manual, own)

* Device Integration & Simulator Enhancements: developed and refactored cash handling device simulators and native layers (cash dispensers, recyclers, readers, coin dispensers/roll dispensers), added new functionality and improved simulation accuracy, supported various programming environments (Java, Java FX, C++, C#, RAP, XFS)

* Build Systems & CI/CD: introduced and maintained CI/CD infrastructure (Jenkins), developed build pipelines for client/server projects, introduced new build tools (Gradle with Kotlin)

* Migration & Modernization: migrated projects from Subversion to Git, Java 8 to Java 11, Eclipse to IntelliJ, refactored and modernized critical components for maintainability and performance

* Automation & Reporting: created automated jobs to generate regulatory transaction reports (ECB, OeNB), built and configured automated CI server backups

* Documentation & Knowledge Sharing: authored comprehensive documentation for CI server configuration and use, Git workflows for development and release processes

* System Integration: integrated third-party interfaces such as KEBA’s RESTful Error Correction Assistance system

* Coordination & Planning: led the planning and execution of significant infrastructure transitions (e.g., source control migration), coordinated development for multi-feature rollouts

Project: CMX Mobile Protocol Tester / Protocol Framework, LTE Stack, NR Stack

Build Systems & Tooling:
* Maintained and enhanced GNU Make-based systems, enabling ClearCase/RTC integration and porting tools like Retriever to Linux (C++, p7Zip).
* Developed automation pipelines in Python, Groovy, and Jenkins for builds, releases, and artifact management via Artifactory, with support for multiple compression formats.
* Created developer productivity tools, including a ClearCase/RTC synchronizer, RTC snapshot comparison client (Java), and build regression test framework (C#).
* Designed and implemented NGBuild, a CMake-based build system and dev environment for multiple protocol stacks, with Python module support, code generation (ASN.1, MDL), and library creation.

Migration & Knowledge Transfer
* Led migration of large C++ codebases from ClearCase to RTC, adapting and extending build systems for compatibility.
* Produced technical documentation and training materials; executed smooth handover of NGBuild and Retriever to successor teams.

Requirements & Evaluation
* Gathered and documented 125+ requirements and 101 evaluation criteria for next-gen build systems across multiple product lines.
* Evaluated 10 build system candidates (e.g., CMake, Bazel, Meson) and delivered 400+ pages of analysis with formal presentations.
