I am a software developer using mostly Java and SQL
(T-SQL and PL/pgSQL dialects) at which I am expert.
Also, for 2 years I used to work professionally with C# but that
was more than a decade ago and I haven't practiced it since.
I have M.Sc. and Ph.D. in Computer science
(Ph.D. is in Bioinformatics in particular).
Long ago I studied in a mathematical high school,
and I did a lot of competitive math too.
I like math and pure computer science a lot.
I am open to freelance work which is somewhat related to
algorithms, mathematics, statistics, data science, etc.
