About

I am Thomas Zimmermann. I am the creator and maintainer of picotm, the system-level transaction manager. My professional interest is in transactional, distributed, and operating systems; systems development; and low-level programming.

Professional

I offer professional support for picotm. If you are interested in training, consulting, or anything else around picotm, please reach out.

I have been around in FOSS for roughly 20 years and been programming mainly in C and C++ since 2000. I have experience with the complete software stack, from hardware emulation in QEMU to Linux drivers to system’s programming, to graphics programming with OpenGL and GTK+. I (re-)designed the low-level communication and driver architecture of Firefox OS during my time at Mozilla.

I hold a University degree in Computer Science (Diplom-Informatiker, comparable to M.Sc.).
