Profile
Veteran software developer and systems engineer experienced in multiple fields with a shy of 20 years professional experience. FOSS enthusiast, honorary member of Macedonia's Free Software NGO and Belgrade's first hackerspace. Designed and implemented distributed and monolith systems in the cloud, on-site and in hybrid infrastructures. Keen on refactoring for the greater good. A long time GNU/Linux user of many flavors, currently endeavoring to use Fedora CoreOS, or any other OSTree based distro in a production environment. My Linked-In, GitHub and my selfhosted Gitea server may provide more info if needed.
Skills and toolset
Python is the language and ecosystem I have the most experience with. I've done a lot of web apps in Django, Flask, FastAPI and make heavy use of SqlAlchemy. Nowadays I use AsyncIO for async programming, but used gevent a lot in the past as well. I'm obliged to say I've got to use most of uWSGI's features and love it for its robustness, richness, large set of configuration options and wonderful documentation.
Huge fan of PostgreSQL with some NoSQL experience in Apache CouchDB. I have fair experience with Apache Kafka, RabbitMQ, MQTT, ZMQ, gRPC for message distribution and make use of Protobuf and Cap'n Proto for packing data before sending it through the wire.
Professionally I used to manage infrastructure on AWS, GCP, OpenStack and employed Ansible on multiple projects. Docker was a thing I've used a lot in the past, but switched to Podman due to its daemon-less, free nature (as in freedom) and its Kubernetes compatibility.
Hobbies and Languages
I spend most of my free time writing Rust, from lock-free queues to web applications in WebAssembly (must also mention that Elm provided me with one of the greatest hobby-programming experiences ever). Recently I've been busy with an embedded application in Rust for tracking e-bikes on an esp32 with a sim module.
I'm an avid table tennis player, frequent hiker (~100k steps/week), pizza and bread baker and an ordinary everyday cook. I also enjoy playing video games, mostly football when in good company.
Macedonian is my native language. I speak English and Serbian fluently and have a fair German knowledge with a C2 degree in 2001.
