My name is Serghei Iakovlev, and you’re looking at the 4th reincarnation of my web presence. I use this blog to share ideas and code snippets using my favorite languages: Haskell, Common Lisp, Ruby.

My GPG public key.

I’m a programmer. I’m mostly focused on creating Zephir Language, building parsers work with static and semantic analysis and research in high-performance compilers: advanced analyses and optimizations for high-performance computing.

For years now my focus has been on building and improving tools that make developers’ lives easier and their time more effective.

I’m part of Phalcon Framework, full-stack PHP framework delivered as a C-extension. I’m Codeception team member. I’m currently working at PDFfiller, a comprehensive online document management platform that provides the services of an online editor, cloud storage platform, and a signature request manager all in one package.

When I’m not working, I’m enjoying watch documentaries, science fiction movies and sometimes play Mahjong or Go.

I’m available for consulting as well.

I love open source, Haskell, Common Lisp, Ruby and live in Emacs on Linux/macOS.
