Profile
=======

Skilled software developer and systems engineer experienced in multiple fields
with 15 years of professional experience. FOSS enthusiast, honorary member of
Macedonia's Free Software NGO and Belgrade's first hackerspace. My `Linked-In

(https://www.linkedin.com/in/vladan-popovic-957ab733) and `GitHub
<https://github.com/vladan>`_ (https://github.com/vladan) profiles may provide
a bit more than stated here.

Skills and toolset
------------------

Extensive knowledge of the web stack. Develop, design and automate distributed
and monolith systems on various infrastructures. Keen on refactoring for
the greater good. Striving for balance between meeting business needs and
producing maintainable, tested and well documented software that wouldn’t be
overwhelmed by technical debt.

* Long time GNU/Linux user of many flavors like Arch, RHEL, CentOS, Fedora,
  Debian, Ubuntu, Alpine, etc.

* I use VIM and Emacs as text and code editors / IDEs, mainly Sphinx (rst) and
  PlantUML for documentation.

* Python is the language and ecosystem I have the most experience with, mostly
  web with Django, Flask, SqlAlchemy, etc. Async network communication with
  gevent and asyncio, small helper scripts that are too complicated to implement
  in bash, automation scripts, etc.
  Rust is lately my No.1 choice for most of the software I write and use, from
  low-level queues to frontend web applications in WebAssembly, for which I also
  use Elm with great joy.

* Virtualization with KVM / QEMU, libvirt and virt-manager. Experimented with
  crosvm, Firecracker, Ignite and similar new technologies.

* Service / infrastructure management on AWS, OpenStack, Apache Mesos, Docker
  and Kubernetes. Ansible for deployment automation.

* I have a fair experience (> 10 projects) with GitLab CI and Jenkins. Also
  experimented with Travis and Circle CI, but never used them for actual
  projects. Very passionate about GitLab, it gave the best experience so far.

* Experience with Apache Kafka, RabbitMQ, MQTT, ZMQ for message
  distribution and Protobuf, FlatBuffers, Cap'n Proto for packing objects.

* NoSQL with Apache CouchDB and a solid experience with PostreSQL.

Languages
---------

Macedonian is my native language. I also speak English and Serbian fluently
and have a fair knowledge of German, with a C2 degree in 2001.
