PDU: software1. Participating in memory database of GMDB R1. The version is developed by the indian team in the inda. Because the indians develop at will, no layering , serious couping and massive use of recursion(very slow in aix), I analyse the codes and get a result. The result is that the version is failed. It's not fit to develop and maintance. Never products. I advise our PM to give it up. At last, our PM get my advice. Development results: finishing changing memory to share memory in GMDB R1. Developing kernel codes about 1500 lines, cover 12 files. Developing gmstat tool that query database.2. Developing GMDB R2, compete with TimesTen of oracle. The performance of query and update is higher than TimesTen. Redesign tools frame to easy developing and extension. The tools frame can support gmstat complicated functions. In the begining, a lot of experts think gmstat can't be developed successfully. Because memory database is complicated, including a lot of types locks and high data query, high performance, the experts think the kernel can not support interface to gmstat. By my analysing and prospect, i think gmstat can come true. Finally i develop gmstat successfully. The tool plays an important role in kernel developing. Find bugs in time. Help to find a lots of bugs, for example controlspace loading failed, chain in circle, index value abnormal, redo information error. Gmstat can query GMDB's status, status of tablespace, systables,index information, GA information. Development results: developing gmstat about 18000 lines, our team get president's Reward Order, give us gold medal team.3. Charging the GMDB' installing and upgrading. Explaining GMDB'knowledge and leading teams to develop clone and configs are centrally modified. using python to develop checking on line. Development results: solving history difficult bugs' list. Restruct the checking , 20 gmrecover's small demands, leading teams to finish development tasks on time and high quality.

Leading more than ten people to develop the 5cworld product. Using VC++ to develop windows apps. The server is php + mysql. Participating in frame design and developing design. Leading and finishing Three-tier framework restructure. Finishing the separation of data from UI. Getting our boss' praise. About the restructure, i first try in one modular. After success, develop the rest 7 modulars. Participating in discussing the technical direction and designing methods. At last, finishing the restructure. About the difficulties, the complicated coding, memory vulnerability,the complicated dependency, making a lot technical try to the big redundant coding.

1. Using VC + access database, developing the collecting software of a temperature device . The software can collect 20 points of temperature in the meantime. Because the control of VC can not be fit, i use drawing line api to draw lines of the temperature. Make the collected data put in access. Can check the history data and nowtime data. Using serial interface, collecting data four time in one second. At last can export in excel.2. Car DVD software developing. On mips frame, embeded developing on wince os. Developing mobile digital TV. Collecting digital signal by digital antenna. filter video streaming and analyse channel information to show the information on the app. Using suspension button , solve the video button issue. Developing DVD player, analog television , radio apps. Using threads, stl technology. The developed products are sold well.
