At the end of 2017 Keymile AG in Bern has been acquired by ABB Schweiz AG.Further architecture design and implementation activities, including but not limited to:- migrating micro-service layer to Spring Boot 2 (Spring 5), introducing Spring WebFlux and asynchronous development in Java 8 (to the team and myself)- redesigning the current E-NP architecture with focus on utilising the micro-service layer as much as possible

Senior Software engineer (C++ / Java / Python) in the Network Management System team. Main developer of the MPLS-TP Control / Service Plane in C++ and Micro-Service Layer in Java. Product Owner deputy in SCRUM and later in SAFe methodologies.Main developer of Ethernet Network Package (E-NP) providing support for MPLS-TP protocol (C++03 and recently C++11, Java 8)Active development in the legacy C++ system- Responsible for maintenance and active development of new features of the E-NP (MPLS-TP) managerDesigning and implementing new micro-service layer (Java) on top of the legacy monolith application (C++), using: - Spring Boot 1.5, Spring MVC, Spring Cloud (Netflix services), RabbitMQ, Gradle and integrating it within the legacy eco-systemIntroducing Test-oriented development practices:- Google Test & Google Mock framework (for C++ Unit tests)- Designing and implementing testing framework in Python 2.6 for automated system / integration tests (over legacy CORBA API, CLI and new RESTful API)Continuous Integration advocate (introducing fully automated CI workflow from scratch using GIT + GitFlow, Jenkins, SonarQube and Artifact repository)- Adapting Atlassian JIRA, Confluence and Bitbucket to be used for Scalable Agile Framework (SAFe) on the R&D department level- Participating in the research projects investigating the possible use of SDN, NFV and Intent-Based Networking (IBN) in the industry, mission-critical networks

Design and implementation of Supervisory Control And Data Acquisition (SCADA) system. Due to real-time data acquisition and processing, core functionalities has been implemented in ANSI C. Communication with programmable controllers (PLC) is obtained utilizing industry well-known protocols like ModBus RTU/TCP or MBus. Measurements and statistics are stored in PostgreSQL database.Measurement and statistical data are accessed from middle-ware (service layer) application implemented in Java Spring framework (Spring MVC, Spring Security and Hibernate) with northbound interface utilizing RESTful paradigm. Moreover service layer is responsible for a asynchronous measurement notification using ActiveMQ message bus.Visualization of industrial sites is available via web portal - implemented using HTML5/CSS/SVG (Bootstrap and D3.js), JavaScript (Backbone.js / Marionette.js, Underscore.js) and STOMP (for asynchronous communication).

GEANT3+JRAT1 - Research on applying SDN paradigm in the multidomain environment; Investigating the potential usage of the NSI-CS 2.0 protocol in the SDN environment; Testing and evaluating support of the Openflow 1.0 protocol by choosen OF-enabled switches.ADDONAS - Design and developing ADDONAS Control Layer for SDN/OpenFlow-enable metro network (JAVA developer - extending functionality of Floodlight (http://floodlight.openflowhub.org) Network Operating System) as well as coordinating of design and implementation works on other modules (along with implementation in Java Spring framework)

Design and development of the real-time SCADA system for industry. Implementation using ANSI C, PL/pgSQL, JavaScript/PHP/HTML/CSS programming languages and technologies.Implementation of Modbus RTU/TCP and Mbus protocols for communication with the MicroPLC controllers in ANSI C.
