    About

    About
    Experienced across different layers of web development with a strong focus on writing efficient, secure and easy-to-read code. I started programming in 2008 while still in school. At university I developed firmware for Atmel microcontrollers in C and later moved into web development. My main strength is growing projects from small startups into large-scale SOA-based distributed applications that serve millions of users. I have worked both in outsourcing and product companies across a wide range of domains — banking, healthcare, online games and many other web applications. Currently I work at a company that develops DDoS protection solutions and high-performance HTTP accelerators. As a Team Lead I improve team efficiency, help with onboarding, guide teammates through complex problems and carefully monitor internal processes to achieve the best possible results. I also have several complete pet projects that demonstrate my skills — you can find them on my website.
