Thilo Fromm

Lead developer / architect of a distributed RESTful web application in Python / Django for managing a cloud of embedded systems.

Founder of the Ahkera free software project implementing the RestMS message broker protocol.

Introduction and application of SRCUM / Agile Methods, integration into the Employer's ISO 9001-2000 waterfall process.

Project Manager Software of 3 projects implementing digital video recording systems: 3 core developers, 4 supporting developers.

Embedded system firmware development in a 3 CPU system (Philips Nexperia 1505 DSPs), pSOS / tmOsal runtime; system / low level / core programming, PCI, TCP and ethernet drivers and communication libraries programming.

Design and implementation of an OpenVPN based networking concept providing connectivity (NAT traversal, presence) and security (authentication, authorisation, encryption) between mobile (Linux based) GPRS/EDGE devices and workstations. Implementation included a web-based status display and maintenance interface and extensive embedded Linux networking scripting.

Product maintenance and extension of an embedded Linux product line including migration path planning, kernel updates, maintaining / porting kernel drivers, and system runtime analysis.

Embedded Linux “plumbing level” system scripting and run-time sanity checks for system and harddisks, networking scripting for dynamic connections via LAN, PPPoE, and GPRS/EDGE dialup.

Implementation of an embedded linux device protocol translator connecting a VDS security system (serial line) to a Siemens TopSIS building management system (TCP message stream).

Project Manager Software of supporting / auxilliary projects: 1 core developer, 2 supporting developers.

Prototype implementation of an emdedded video grabber / encoder / transmitter device featuring H.263 encoding, RTP/UDP media transmission, SIP signalling, and dual (both ends) NAT traversal.

Implementation of a make based multi platform build system supporting Windows, Linux, Philips Nexperia target platforms as well as linux (gcc) and windows (cl, tmcc) build hosts.

Design and implementation of a layer 3 / layer 4 network simulator (delay, bandwidth, loss) using Linux traffic shaping / routing; remote configurable via a web interface.

Design and implementation of an embedded SIP/2.0 library.

Design and implementation of an embedded Linux video recording system (ARM CPU); setup and maintenance of a roll-your-own compiler toolchain, setup of a Linux ARM root fs, implementation of a USB/DMA device driver, and port of the Linux kernel to a custom PXA 255 (ARM) based machine.

Design and implementation of a digital signature concept ensuring authenticity of recorded video streams for an embedded Linux video recording device.

Hardware Design and prototype production of a video digitizer board a StrongARM development platform; linux kernel driver programming, video server and -client (live viewer) design+implementation.
