  Background
  Xylem Inc. is a leading global water technology company that provides solutions for water… and wastewater management.

  Product owner in a team working on enabling the equipment in the field to connect to the cloud platform for remote monitoring, data logging, reducing operational costs.

  Assignment
  1. Lead a project of developing embedded SW and integration to a cloud platform, converting 5000 4G gateways deployed across the globe to the new standard.
  2. Find/develop a new, technically capable and cost effective solution for a 4G gateway while keeping backwards compatibility.
  3. Find/develop a suitable technical solution to enable camera streaming, power measurement and connectivity for remote pump stations.
  4. Responsible for general IoT initiatives at Xylem Water Solutions AB.

  Task
  Salko is responsible for the technical solution, meaning prioritizing what to implement and when, translating business requirements to technical ones and owning the backlog.
  Working alongside system architects and experts in modems, cellular connectivity, and cloud platforms.
  Working on optimizing provisioning and normal operation. Including integration to the cloud.

  Result
  1. The SW (everything except bootloader and OS) of the 4G gateway was developed from scratch. All customer features are ready and what remains is for production to adapt the new SW and the customer migration to start.
  2. 11 suppliers were initially considered and after a lot of discussions and work, one remains. As of now a well progressed discussion is taking place with this supplier and SW-development is scheduled for the summer.
  3. Deployed 20 pilot stations across the globe - the technical solution works fine but the chosen camera model does not withstand the gases in the pump station and breaks down after X months. Another camera solution is being worked on.

  Master Thesis

  Assignment
  The master thesis Steering System Verification Using Hardware-in-the-Loop (HIL) was a… proof-of-concept investigating possibilities and difficulties of moving calibration of ECU-parameters in car to HIL-rigs.

  Task
  Investigate if it is possible to calibrate major parts of the steering rig ECU in the HIL-rig instead of in the field.

  Result
  The steering system was integrated in the HIL rig.
  Tests were automatizing tests in order to optimize the calibration.
  The conclusion was that it is possible to move parts of the calibration to the rig.
