Welcome outlander

I am Szilárd, the hungarian version of Constantin.

I am a Software developer from Kolozsvár (Cluj Napoca) from the hearth of Transylvania.

I don’t hunt demons or slay vampires. I am more into working with C/C++, Golang, playing around with Particle Photons or watching the Star Wars saga again.

Technical experience

Programming languages, technologies and frameworks

C: I have experience working with real time systems, hardware components, sensors, relays, (etc.) in enterprise IoT projects. I have designed and implemented IoT solutions targeting different type of development boards. The aim of the projects was to implement domain specific solutions for the internet connected devices. During development I have used the following communication protocols: CoAP, MQTT.

Key words: ESP32, Qualcomm boards, Raspberry Pi, Particle Photon, CoAP, MQTT, HTTP(S), XMPP(TLS), C programming language, Unity test framework, Google test, CMake, Docker, CI/CD, GitLab

C++: I have developed cross platform communication libraries for IoT devices using HTTP(S), XMPP(TLS) protocols. I was responsible for creating and maintaining the continuous integration using GitLab CI. The libraries were built for Android (armv7, arm64, x86, x86_64), iOS (armv7, arm64, Simulator, Simulator64), MacOS (x86, x86_64), Linux, (armv7, x86, x86_64) and Windows (x86, x86_64).

Key words: Boost, Poco, CMake, Android, iOS, Unix, MacOS, Windows

Go: I have started using Go in 2015 starting with my dissertation thesis. In this project I have created a home automation platform. The backend service was written in Go, it provided a Rest API to access the service. The user data was written to RethinkDB the sensor data was inserted into InfluxDB.

I have developed command line tools and services for different purposes (job automation, package and configuration managers, software installers, etc.).

VueJS: I have used VueJS and Quasar framework for developing a web application with a Golang backend.

Used tools, SaaS, and IaaS solutions

DevOps: In the last few years I have implemented different DevOps solutions for my projects. I also deployed and managed different services (Jenkins, Selenium, Sonatype Nexus, etc) on K8s.

Kubernetes: created and managed K8s deployments for multiple projects

Key words: GitLab, GitLab CI/CD, Jenkins, GitHub, Travis CI, Docker, Kubernetes, Openshift, Kubernetes, K3s, Terraform, Vagrant, Ansible, AWS
