For a customer in München I (as a part of a team) was tasked to
integrate an FSoE Safety protocol layer on top of an existing EtherCAT
protocol into an existing prototype of safety-relevant application (a
human-machine interaction system).
C/C++, Linux, FSoE Stack Library
(two different suppliers), CPPUnit, JIRA.

For a customer in region Frankfurt am Main: A Battery Management
System product firmware extension and bug fixing. I was tasked to
figure out a lost/legacy procedure of bootloader and firmware update of
a battery management system, fix issues with overcurrent of the battery
load and model a charg/discharge process to verify a correct functioning
of introduced changes for a legacy firmware that has already been
longer time deployed to the end customer.

C/C++, AtmelStudio (not an ASF-based project), 1-Wire serial interface,
Python (to model charge/discharge current dynamics of the BMS)

11/2017 – 2/2018

Platform and communication channel-independet abstraction software layer library design and
implementation. The abstraction layer was meant to hide the connection
and transmission-related details from the application layer software. The
layer covered GPRS and WiFi as a network interfaces and acted as
unified software facade.

C/C++, MQTT/MQTTS. Various ARM-based MCUs on multiple
development boards.

For a customer in USA: Floating/submercing meteorology-buoy controll
software and communication interface design. Proof of concept
implementation.
C++, I2C, KiCad (for connection schematics layout).
The challange on the project was to suggest a compete solution to the
customer, and consider maintenance procedure (the system is difficult to
access once deployed). Requirements analysis was also a non-trivial task
– the customer had very deep understanding and practical experience in
the field but no systematic approach to formulate the acceptance criteria
and requirements in general. I had to suggest an electronics design
as well as software solution (both application and system level). Another
challenge was that the system can be deployed only during particular
weather conditions – making period from November to March not
suitable for testing and effective development. Partial system simulation
has been used to save testing efforts.

For a customer in Ireland: Feasibility study for qr-code recognition
library.C, Make/Cmake, Linux.
Suggested and set up a stress test for most popular qr-code recognition
libraries. Based on processing involving provided sets of images
suggested the library that would cover the requirements. The challenge
on the project was to provide a unified set of metrics to compare
libraries and to prove to the customer that the suggested library meets
the expectations.
