Hello, I’m Lenko Donchev. I’m Software Developer.

I’ve been building software since 1999. Back then I started by building Internet meta search engine in Perl. I sold the search engine for undisclosed sum. I have used many programming languages but Perl still has a special place in my heart.

I have been blessed to work on building amazing software systems like the following:

  • cloud infrastructure and DevOps
  • educational(K-12) and clinical assessments
  • financial trading systems, fault-tolerant real-time feed handlers and market data gateways
  • distributed machine learning - Betting Advisor for betting on horse racing
  • distributed poker game server
  • Internet of things big data platform for retail analytics
  • casino and arcade games
  • petabyte scale financial trading infrastructure

In my free time I like to play a violin or make a violin.

The best way to contact me is through email:

I can also be found on Speaker Deck, Keybase, Twitter, Github and LinkedIn.
