You can achieve the result by the following modifications:
- Use the option
firstinits=true: Use only the first letter of the forname
Declare the format of the names to the order first-last. The order is specified in the name list format sortname. To change this, you can use:
\DeclareNameAlias{sortname}{first-last}
The complete MWE is:
\documentclass{article}
\usepackage[style=authortitle,firstinits=true]{biblatex}
\addbibresource{biblatex-examples.bib}
\begin{document}
Text \cite{companion}
\DeclareNameAlias{sortname}{first-last}
\printbibliography
\end{document}
