Andrei Alexandrescu (born 1969) is a Romanian-American C++ and D language programmer and author. He is particularly known for his pioneering work on policy-based design implemented via template metaprogramming. These ideas are articulated in his book Modern C++ Design and were first implemented in his programming library, Loki. He also implemented the "move constructors" concept in his MOJO library. He contributed to the C/C++ Users Journal under the byline "Generic<Programming>". Alexandrescu worked as a research scientist at Facebook, before departing the company in August 2015 in order to focus on developing the D programming language.

Education and career
Alexandrescu received a B.S. degree in Electrical Engineering from Polytechnic University of Bucharest (Universitatea Politehnica din Bucureşti) in July 1994.
His first article was published in the C/C++ Users Journal in September 1998. He was a program manager for Netzip, Inc. from April 1999 until February 2000. When the company was acquired by RealNetworks, Inc., he served there as a development manager from February 2000 through September 2001.
Alexandrescu earned an M.S. (2003) and a Ph.D. (2009) in computer science from the University of Washington.
More recently, he has been assisting Walter Bright in the development of the D programming language. Alexandrescu released a book titled The D Programming Language in May 2010.
Alexandrescu, Herb Sutter, and Scott Meyers run C++ and Beyond, a small annual technical conference.
Contributions
Expected is a template class for C++ which has been proposed for inclusion in Boost. Alexandrescu proposes Expected<T> as a class for use as a return value which contains either a T or the exception preventing its creation, which is an improvement over use of either return codes or exceptions exclusively. Expected can be thought of as a restriction of sum (union) types or algebraic datatypes in various languages, e.g., Hope, or the more recent Haskell and Gallina; or of the error handling mechanism of Google's Go, or the Result type in Rust.
He explains the benefits of Expected<T> as:
Example
For example, instead of any of the following common function prototypes:
int parseInt(const string&); // Returns 0 on error and sets errno.
or
int parseInt(const string&); // Throws invalid_input or overflow
he proposes the following:
Expected<int> parseInt(const string&); // Returns an expected int: either an int or an exception
