All the contracts and projects have been from Ryobi Systems.As a BrSE, I have undertaken the following projects from Ryobi Systems.Vehicle-mounted Device (HMI) Development Team (up to 2019/04):I developed parts of the Diag App, Reprogram App, and Radio App, and analyzed any issues that arose.VPN Development Team (from 2019/05):As a leader, I held discussions with clients to finalize specifications, created work plans, and synchronized progress with team members daily. I reported weekly progress to the clients and addressed any concerns they had. Moreover, I researched technical aspects that were unclear to my team members and resolved those issues. I developed a VPN server using OpenSSL.From 2019/08, I cross-compiled C/C++ libraries such as asio, lz4, openssl, and openvpn3, integrated them into Android using CMake and Gradle, and created a prototype VPN client. Starting in October, I formally developed device manager apps for Windows (in C#), macOS, iOS, and Android versions and released them by the end of December.From 2020, I began the consideration and design of a remote desktop system. Utilizing Apache Guacamole, I customized it according to client requests and developed a web version of the remote desktop system. Using the FreeRDP library, I created a customizable prototype app for Windows RDP. The device manager app was further developed, adding VPN tunnel connection and RDP connection features.I analyzed open-source software like mattermost, jitsi, nextcloud, and keycloak, integrated them, and designed new features based on client requests. I delegated coding and testing tasks to team members while periodically reviewing the source code and verifying test factors.

I joined Tripod Works and was assigned to work on the following tasks at Aisin AW Co. Ltd.For the VOLVO/BMW group in the company, in order to address BUGs, I used HILS for test reproduction. After obtaining the CAN log and analyzing it, I identified issues in the code and proposed solutions. After making the modifications, I tested them for validation.

Worked on design and development of 【Baseband Controller】 in 【Micro Radio Equipment Controller】(MiddleWare between Docomo and Nokia Siemens Network) from zero.I'm in charge of Dedicate Channel(R99 and R5 Call) create, hard-handover, and soft-handover.This project was very smart, using automated testing to greatly ensure product quality.Then in February 2013, project was successfully done and i was transferred to study 【eNodeB UE functions】.After more than half a year studying, the Japanese took development back, because deadline could not be delayed said by Docomo, so i was transferred back to continue design and develop 【Baseband Controller】, but in new 【High Density Base station Digital processing Equipment】, in charge of Dedicate Channel(R99, R5, R6 Call) . Seeing the code I wrote in 2005, it's so immature that I'm embarrassed to admit it was me.

In the first year, worked on android/iOS app projects, developed three android games and one iOS app.Then in the next half year, worked on a Perl/PHP project (Mail data trace track and analysis) .Since October 2011, dispatched to [Panasonic Software Development Center Dalian Co.]

Embedded development of OKI Printers. In charge of Status Management Module. Responsible for parsing, fixing BUGs, and testing for verification.

First job, old times. most time use c language to develop middle firmware(SD card data copy. MP4 file decoder, render) of phones (linux core) of panasonic. then iPhone came, all over. And also use c++ to develop call process controller firmware of 3G base station of panasonic(to ntt docomo). and 3 months excel vba + oracle database project experience. and 8 months visual studio C++ MFC application develop experience. It was a good company, maybe the first, the best?big effecttion to my work personality. and give me the most important thing - the formal procedure of software development. and also my best friends here. Thank you, Mr.P.
