Graduated mathematician specializing in computer science with practical experience spanning over 20 years. Participated in the development and implementation of all types of applications. Designed and developed many utilities, programming libraries, open-source tools, and critical online services with a large user base.
Expertise in all types of automation of Windows and Unix-like operating systems – unattended installations, helper tools, automatic testing, CI/CD, integrations, GUI and browser automation, smart things, etc. I am highly experienced in a number of programming languages and paradigms, object-oriented design, functional programming, Windows/Linux administration, and DevOps practices.
Passion for design of full web service lifetime which includes all supporting infrastructure and starts from first lines of code, over design and testing, to production and maintenance, up to eventual archival. Almost anybody can make it a year or two on a project, but real problems come later when entropy builds up on projects that span more than several years.
In my free time, mostly occupied by open source programming, audio synthesis, medicine, nutrition, cooking, gaming, and being a father.

Treasury Bank Account Statement Service produces statements for 200K+ bank accounts (all public funds accounts of the country).
Most of the statements are produced daily in 4 formats and few are produced continually during the day, every few minutes. Every second of performance counts - full generation never exceeds one hour and individual few seconds, which my team achieved with a single commodity server. Service replaced dozen of home born systems decades in development that were generating this data for many hours, even days. The most critical part of the service runs around 1 AM and must have no errors of any kind. To achieve that, we created several notification tools that guaranties that people do wake up and fix eventual incident. During 3 years of production, we had 0 observable incidents generating several gigabytes of data daily.

IDP - 2020-2024
The government Subsidy Registry is a Serbian government service that allows every citizen to apply for a direct donation of 100 EUR as an economic help measure due to the Covid 2019 pandemic. This service had unreal expectations: to be done within a single month, to serve millions of requests in a single day of highly classified data, integrations with all banks and dozens of ministries, to be highly secure and resistant to malversations and attacks and with all of the citizen data to be hosted in the country. This was all to be done in the military emergency state where most of institutions didn't have a regular working schedule and working in severely diminished capacities, unregular working time and 100% remote.
My roles on this project included: solution architecture, complete infrastructure design/installation/management, CI/CD, automatic testing, project management, support and so on. The project is done, as usual, with open source technologies, commodity hardware and on-premise without using any public cloud except CloudFlare (only for DDOS protection).
The service successfully registered 2M citizens in a few hours, and almost all Serbian citizens the next day, without downtime, processing more than 10M requests per day while utilizing 1-3% of each included server resource. Nobody expected this kind of rush - initial estimates were the order of magnitude lower.
This is an achievement and sleepless month that I am most proud of. Success stories for this could be found on the entire Serbian Internet.
The service had 6 separate instances in different periods of pandemic.
With my team, I support critical Treasury infrastructure: Redmine, Zimbra, DNS, NTP, PKI, MS SQL Server, Gitlab, Nginx ...
