+
+I proudly announce that ReactOS Deutschland e.V. has hired Jérôme Gardou to work full-time on the ReactOS kernel's memory manager for the next 3 months.
+
+Jérôme is a ReactOS veteran who has been contributing to the project since 2009.
+He has deep expertise into nearly all parts of ReactOS, ranging from various user-mode components (mostly related to low-level graphics) over their kernel-mode counterparts and down to bare-metal components like the kernel memory manager.
+
+During the upcoming months, Jérôme is going to overhaul the `Mm` (Memory Manager) and `Cc` (Cache Controller) components of the kernel.
+Both of them are core parts of the operating system, which are involved in every memory request and file operation.
+Improving them is expected to have a substantial effect on the overall stability and performance of ReactOS.
+
+Going into the nitty-gritty technical details, Jérôme first wants to make `Cc` a client of `Mm`.
+Instead of creating a cache entry for each file section (as ReactOS does right now), let's do it the other way round:
+Create an `Mm` section for each cached file and page it in when the filesystem driver requests it.
+This has several benefits:
+* We use less address space in `Cc`, as each file section will not create a cache entry anymore.
+* The ReactOS kernel's architecture gets closer to the Windows original, thereby improving compatibility and maintainability.
+* Simplified development in both `Mm` and `Cc`, as that step makes the kernel more modular.
+
+The work will be followed by integrating file section creation into the code path of the "modern" ReactOS memory manager (internally known as `ARM3`), registering pages into process working sets, and finally implementing a thread for proper memory paging.  
+For parts that are still unclear as of today, Jérôme plans to write additional kernel-mode tests.
+
+This announcement comes just a few months after we [hired Victor Perevertkin](/project-news/victor-perevertkin-hired-full-time) to work full-time on the storage stack.
+He is still working for us and just about to finish [porting the Kernel-Mode Driver Framework (KMDF) to ReactOS](https://github.com/reactos/reactos/pull/3234), which will enable us to leverage many open-source storage drivers written for Windows.
+
+With two full-time hirings, 2020 is definitely a landmark year for the ReactOS Project.  
+Many thanks go out to our generous **donors** for making this possible!
+Your [continued donations](/donate) already enable us to finance two developers, and hopefully many more in the future.
