My name is Andriy Kryvtsun (Ukrainian: Андрій Кривцун) but people often call me Andy (sometimes even Andrzej or Andre).
I wrote my first program in BASIC computer language in my school notebook with a regular pen in the late 80s as I didn’t have access to a computer at that time. My first personal computing device was a Soviet programmable microcalculator Elektronika MK-61 and I recall with great pleasure weeks spent writing and launching programs on it (actually those programs were something between binary codes and Assembly language).
Currently I’m a senior software engineer with over two decades of professional experience in the IT industry.
I’m definitely a backend guy. My actual technical stack consists of JVM-based computer languages (mostly Java, but also Kotlin and Scala too) and related technologies (like Spring framework, Hibernate, JUnit etc.) but in beginning of my career there was a period when I worked as a system network administrator and even passed Oracle Database Administration exam.
I have experience working in product and service companies both in my home country Ukraine as well as abroad. I lived in the New York City area for over four years working onsite in a bank. Since then I have fallen in love with street photography and hate the office dress code.
My professional interests lie in the field of software architectures, Domain-driven design (DDD), functional programming and creation of distributed systems.
I’m a Sun Certified Programmer for the Java 2 Platform (SCJP)
AWS Certified Cloud Practitioner,
and Microsoft Certified Professional (MCP).
