with more than 15 years of professional experience. FOSS enthusiast, honorary

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

Experienced developer designing and automating distributed and monolith systems
on various infrastructures. Keen on refactoring for the greater good. I'm a long
time GNU/Linux user of many flavors (regularly use Arch, CentOS, Fedora, Debian,
Ubuntu, Alpine, etc.). As an IDE I use neovim and Emacs, preferably Sphinx (rst)
and PlantUML for documentation but markdown happens on daily level as well.

Python is the language and ecosystem I have the most experience with. I've done
a bunch of web apps in Django, Flask, SqlAlchemy, etc., used async network
communication with gevent and asyncio, RPC for some IoT projects, in love with
uWSGI ... and also write small helper / automation scripts in Python (and bash
if really small) almost every day.

Rust is the language I spend most of my free time with, from low-level queues to
frontend web applications in WebAssembly, for which I gladly use Elm ...
Ocaml 5.0 (with Eio) is next in line :) some things from this paragraph can be
found on my personal gitea server: `https://gitea.vp.mk/explore/repos
<https://gitea.vp.mk/explore/repos>`_.

I have fair experience with Apache Kafka, RabbitMQ, MQTT, ZMQ for message
distribution and Protobuf, FlatBuffers, Cap'n Proto for packing objects. NoSQL
with Apache CouchDB and fair development experience with PostreSQL.

For virtualization I use KVM / QEMU for personal needs, and I'm pretty fond of
the new microvm approaches such as Firecracker, Cloud Hypervisor et al.
Professionaly I used to manage infrastructure on AWS, Azure, GCP, OpenStack.
Used to love Ansible, but now I'm more of a fan of Fedora CoreOS / Silverblue
(OSTree based distros) for building images and setting up workload environments.

Languages
---------

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