2016 - 2022: Setting up the security core of the microcontroller

Role: Senior Embedded Software Developer

Customer: Continental/Vitesco

Tasks:

The client, responsible for products? cybersecurity, needed support for the security core of the microcontroller: activation, states? change, and

data exchange with the main cores.

• Increased by 4x the user experience by implementing a software module to activate the security core and read its status, and another module to set up the security settings, such as authorizations and passwords.

2013 - 2022: Flash memory services

Role: Senior Embedded Software Developer

Customer: Continental/Vitesco

Tasks:

The client, responsible for the software components loading into the electronic control unit memory, required a set of services to handle large

amounts of data to be written, read, or erased from the flash memory of the microcontroller.

• Enabled the data control over more than 95% memory capacity, by implementing services to allow the user to request writing or reading a given amount of data in or from the Flash Memory or RAM.
• Enhanced by 2x the integrity check of the data, by implementing a service for the checksum calculation over large ranges of Flash Memory or RAM, while considering the other OS tasks scheduling.
• Enabled the erase for 100% capacity of the Program Flash, and more than 95% Data Flash memory capacity by implementing a service for erasing a range of memory; due to its long time operation the service considers the other OS tasks scheduling.

2020-09 - 2021-01: User authorization in warranty return shops

Role: Senior Embedded Software Developer

Customer: Continental/Vitesco

Tasks:

The client, responsible for electronic control units warranty return service, required a process to authenticate a user before authorizing him

to the reprogramming mechanisms.

• Improved by 2x the security measures by implementing a protocol of user authentication by messages sent in a specific time frame.
• Reduced by 80% the risk of unauthorized gain of access to the software code, by integrating the above-mentioned protocol in a single software component which is erased after the authentication process.

Skills:

Microcontroller Startup, Boot Control, External Communication: CAN

Role: Senior Embedded Software Developer

Customer: Vitesco

Tasks:

The client, a designer of the electronic components of a car, needed software to support the possibility to transfer data between microcontrollers situated on the same electronic board, at a high speed.

• Increased by 4x the communication speed by implementing the software module to handle the high-speed serial link feature of the microcontroller, and enable the user to request the sending and retrieving of the needed data by a simple, easy-to-use, protocol.

Skills:

Infineon TC3xx microcontroller internal communication: HSSL

Role: Senior Embedded Software Developer

Customer: Continental/Vitesco

Tasks:

The client, responsible for the electronic control units' reprogramming, required the software to skip the authentication process of the toolchain

user in certain circumstances where the user authentication is not relevant.

• Improved by 3x the user experience with authentication by implementing a strategy of skipping the user authentication and granting the user access in those circumstances.
• Decreased the interaction time by up to 10% by avoiding the processing of a dummy certificate sent by the user of the reprogramming toolchain.

Skills:

Role: Senior Embedded Software Developer

Customer: Continental

Tasks:

The client, responsible for products? cybersecurity, needed a service to get the possibility to set up the tuning protection over the memory and

debug ports. The tuning protection is meant to reduce several risks that may affect either the product owner or the producer.

• Reduced risks by more than 90% by implementing the software mechanism that deals with the microcontroller capacity of preventing unauthorized access to its memory and access ports.
• Increased by 2x the experience of the user by implementing a software module that lets the user exchange the setup data in a compact and easy way.
