04/2017 - 04/2019
Design Engineer
Self Employed; Logithoroughfare AB (Industry and mechanical engineering, < 10 employees)

Worked in 3M Peltor Svenska AB on an assignment Sigma Technology Mid AB (from May 2017 to December 2018).
* Did firmware development on ARM-based processors for establishing a network with multiple BLE devices and routing data traffic of commands and responses from wireless modules. Different low profile, battery-operated PCBs have also been designed and tested.
* Did PCB design for different projects which includes the design of power supplies, amplifiers, and audio electronics. It also includes bring-up of electronics, low profile SMD
soldering, and Bluetooth qualification tests.

01/2016 - 03/2017
Consultant
ALTEN Sweden AB (Industry and mechanical engineering, 1000-5000 employees)

* Worked with different companies named Kongsberg Automotive AB, Cobham Gaisler AB, and Unique Pyrotechnic AB. In housework includes the design of analog and digital electronics for current measurements on ignition coils, integration for RMS value of current and control using operational amplifiers. Developed a converter module for power line communication on a customized RS485 interface from a referenced design. Did calibration and testing in the production of the units.

* Did PCB design for seat heaters with LIN interface for JLR. Did documentation at different stages of design/development like FMEA, HWDD and test specifications. Testing
of electronics according to automotive standards and environments.

12/2014 - 01/2016
Design/Test Engineer
INRESOL AB (Industry and mechanical engineering, 10-50 employees)

* Development of an automation solution for Sterling Engine which includes three-phase inverters and firmware development on DSPIC processor by Microchip. Motor control inverter for PMSM motor has been designed with the capability of 5.5 K watt of power (565V and 10A). Isolated off-the-shelf DC to DC (330V to 12V) has been selected and used. The system also includes the battery management system and a grid inverter. Did project management.

12/2011 - 10/2014
Senior Design Engineer
Bitidentify Sweden AB (Industry and mechanical engineering, < 10 employees)

* Developed a solution for cyber hacking from specification to end system design on FPGA.
* Designed several state machines for controlling and modifying the traffic of a storage device attached to the SATA-III interface according to the SATA specification and requirements of the concept. Implemented behaviour as a pseudo-SATA host and device between the SATA host controller and SATA device controller. Designed test cases for simulation and testing using ChipScope on off-the-shelf FPGA boards.
* Did management by the scheduling of the project and implemented the solution on off-the-shelf hardware consisting of an FPGA board and computer system. Did demonstrations of the setup to different expected customers/investors and described system-level usage and importance.
* Responsibilities also include the schematics for high-speed interfaces, switch-mode power supply, EMC design and connections to a computer motherboard.

07/2011 - 10/2011
Design Engineer
EUR AB (Industry and mechanical engineering, < 10 employees)

* Developed firmware for ARM7 and Cortex-M3 processors. A MATLAB algorithm for assessment of adverse health effects in the lumbar spine due to multiple shocks was implemented on a Cortex-M3 processor. The system includes RF transceiver, accelerometer and flash memory.

08/2010 - 05/2011
International Scholar
IMEC (Interuniversity Microelectronics Center) (Industry and mechanical engineering)

* Validated a mixed-signal ASIC of sigma-delta modulator. Developed low noise and low distortion electronic circuits, data acquisition setup and FFT based performance analysis using MATLAB and LabVIEW. SNR of the input signal, acceptable jitter of the sampling clock, requirements of noise on the power supplies, signal integrity, and EMC
are investigated and implemented. Digital interface (Customized SPI) of the modulator chip is being programmed with MSP430 for configuring different modes
