## 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 flavours, currently endaevouring to use Fedora
|
||
CoreOS, or any other [**OSTree based
|
||
distro**](https://gitea.vp.mk/vladan/workstation-ostree-config) in a production
|
||
environment. My
|
||
[**Linked-In**](https://www.linkedin.com/in/vladan-popovic-957ab733),
|
||
[**GitHub**](https://github.com/vladan>) and [**my selfhosted Gitea
|
||
server**](https://gitea.vp.mk/vladan) 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.
|
||
Nowdays 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, 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.
|
||
|
||
Professionaly 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 compatability.
|
||
|
||
### Hobbies and Languages
|
||
|
||
I spend most of my free time writing Rust, from [**lock-free
|
||
queues**](https://github.com/filipdulic/bus-queue) to [**web applications in
|
||
WebAssembly**](https://git.vp.mk/ui) (must also mention that Elm provided me
|
||
with one of the greatest hoby-programming experiences ever). Recently I've been
|
||
busy with an [**embedded application in Rust for tracking
|
||
e-bikes**](https://gitea.vp.mk/e-bike-tracker) 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.
