I was responsible for a group developers. Duties include design and develop a thorough clinical system from device to database/cloud storage. The application provides an interface for a specific clinical device (A Neuro-Audio based system for tinnitus evaluation and rehabilitation) to evaluate hearing problems. Extensible architecture, synchronizing via cloud, considering clinical protocol for calibration, personal information confidentiality and durability were the main challenges of this project. I have also involved in driver development of an signal generator on I2S bus and real-time guaranty of data buffering.

In this project I was working on different parts of a customized Linux operating system. My responsibilities were participating in diverse range of challenging R&D system software projects. Including: (1) Deploy a customized real-time Linux kernel on specific embedded board. Adapting drivers with hardware characteristics, remote kernel debugging, performance analysis and real-time evaluation were main challenges in this project. (2) Implementing a module for GRUB 2 to distinguish physical and virtual hardwares. Apply this module in ISOLINUX boot loader to install virtualized operating system via CD-ROM. (3) Implementing a tiny hyper-visor engine for key management by preparing a virtualized hardware interface for read/store data in block devices. (4) Encapsulating device drivers to enrich high availability and improve accessibility.

In several years I developed real-time and industrial applications for controlling movement of cutting CNC machines which are working on industry, so called CNC Controller (CNCC). Three version has been developed which are: (1) A specific hardware based on AVR processors and corresponding desktop application. The application imports Autocad design files, sends navigation data to the board and board stores it in a local flash storage. Through PC and remote controller, it could control movement of a 3-axes CNC machine for cutting sheets of steal according to the Autocad design. (2) A firm real-time application for controlling CNC machines directly via PC, using RTX environment. (3) A soft real-time application for controlling CNC machines directly via PC, using windows multimedia timer. (The code is OpenSource)

VOI is one of the most rapidly growing startups of Sweden and its core business is to provide e-scooter/e-bike sharing on Eurpoean major cities. In this company I had the chance to contribute in a high demand project at very agile and fast growing environment. I joined VOI as a senior software engineer and I involve in multiple tasks at tech team. As an example I was responsible for design and implementing a rule-engine pipeline to apply safe rule-action on live customers. Main challenges in this project was designing a DSL language combined with architectural decisions of a compatible solution with Kubernetes orchestration that is able to scale with time-based and stateful actions.
