I worked as a back-end developer during the engagement. Delivered enterprise solutions as a Salesforce Developer across multiple client projects using Scrum Agile methodology. Implemented Salesforce features and integrations to support client business requirements and operational workflows. Worked with the data engineering team to develop data processing pipelines and visualization solutions on Microsoft Azure Data Factory. Assisted with backend refactoring and system improvements to enhance system maintainability and development efficiency. Contributed to the integration of Salesforce Einstein Agent Bot, enabling intelligent automation within enterprise platforms.

I worked as a software engineer in the Resource Center of China Unicom Yunnan branch. During this serving time, I was mainly engaged in the development and iteration of some internal systems and a data visible central platform. Among them, the data visible central platform is a project which was built from scratch.

As the project leader of this project, I led a small team of four teamates to achieve it from sorting out business benchmark requirements with leaders of other departments to designing the architecture of system, designing the database, extracting transactional data, development and launch.

The back-end technics mainly covered Spring Cloud framework, while the front-end technics covered a React framework named Ant-Design. As for data extraction, we used an ETL tool named Kettle and combined it with the traditional Oracle stored procedure. For the internal business operational system, I was primarily resiponsible for the development of orders schduling module, which was essentially an extended development based on the old system architecture from AsiaInfo, the target of this achievement was to integrate existing business processing engine. Through my whole serving time, I've extended my capability in managing projects and controlling the risk of projects, I've as well gained novel awareness in software development.

I worked as a Java Software Engineer in the Goverment Development Department of Neusoft Group Yunnan branch. The primary business and responsibility of this department is to build information systems for the medical insurance in the whole province, furthermore, the construction of management and charging systems of most hospitals and pharmacy which supports medical insurance service.

Systems consist of few charging modules which are built with PB and most management modules based on B/S architecture which are built with Java. The database is mainly Oracle. Most projects based on Struts, Spring and Hibernate composite framework, while some of them also uses MyBatis as ORM. The work of development is also involved with multi-threading, scheduled tasks and PL/SQL stored procedure. During this serving time, I've greatly enhanced my ability on using database tools and database development. Apart from thtese works, I've as well taken part in the develpment of an IOS application which is used to provide quering functionality for medical insurance business. I was coding for the user interfaces and the data demonstration in this project, the IOS application needs to invoke interfaces from the back-end service which is developed with Java. In some medical insurance charging systems, the complete business involves from outpatient service to prescription, distribution, hosptitalization and discharge, among which also including the whole process of drug inventory management (warehousing - outbound - distribution - inventory - balance).

Most projects I've participated were involved with prototype design, database design, font-end and back-end development. During this period, I've not only improved my ability in Java programming, but also thoroughly gained a comprehension about the principle of widely used Web frameworks developed in Java and the MVC architecture, simultaneously, I started to learn about agile development.

I worked as a Software Testing Engineer in the processing management department of Yunnan Nantian Electric Information Industry. I was responsible for white testing on ATM related systems and modules. Most systems were based on Spring, Struts, Hibernate and FreeMarker composite framework. During this period, I started to learn software developing knowledge and some basic skills of Web development.
