Global Training App

I spearheaded the comprehensive development of a web application for a prestigious German car manufacturer, 革新新产品发布的全球培训计划.

This dynamic application empowered training planners to strategically apply rules across a world map, 准确估计各国的培训需求, roles, and more. Post-planning, 它为每个国家编制了全面的培训摘要, 促进市场业主之间的讨论和合同签订. 可定制的规则简化了参与者的计算, 利用汽车制造商的员工数据库获取实时数据.

前端，用Node构建.js和Angular，与PostgreSQL数据库无缝协调. On the back end, Java and Spring Boot, 辅以有策略地使用lambda, ensured a successful 2-year development journey that significantly transformed the company's training process, 取代过时的电子表格与精确, efficient, 数据驱动的解决方案.

绝地求生冠军赛分析

I embarked on a personal side project that culminated in a remarkable web application tailored for PUBG (Player Unknown's Battlegrounds) enthusiasts. This innovative platform empowered players to orchestrate tournaments and scrutinize their gameplay performance. 利用官方游戏API, 它提供实时比赛分析, 为团队和个人构建全面的计分板. 用户可以深入了解玩家的表现, 从整体成就到每场比赛的统计数据. 进一步提升体验, 我引入了一个重放功能，允许用户重看比赛, 完成记录的游戏内事件, 所有这些都在浏览器中显示.

Remarkably, 这款应用迅速在电子竞技社区获得了关注, amassing over 10,在没有任何营销努力的情况下，3个月内获得了1000个独立日用户. 事实上，游戏中的所有比赛都采用了我们的平台进行计划和分析.

这款应用也迎合了职业玩家的需求, 提供深入的比赛分析, movement scrutiny, 以及通过回放功能来发展战略.

这个项目在负载优化方面是一个宝贵的学习经验.

No-code Platform

我是一个开创性的无代码平台背后的关键核心团队成员. 我们制作了一种类似于虚幻引擎蓝图的可视化编程语言, 通过合并数据简化应用程序开发, UI, and logic into one layer, 消除了传统分层的复杂性.

我的贡献包括构建一个与MySQL兼容的独立数据库层, Postgres, and MS SQL. 我领导了从纯HTML和JQuery到React和Webpack的前端转换, enhancing usability. The platform facilitated collaborative work through WebSockets, and its back end was entirely Node.js with TypeScript. 我们提供了各种各样的构建模块, from basic to high-level, akin to Excel formulas, 使没有编码经验的用户能够使应用程序适应他们的特定需求. 此外，我将UI编辑器修改为WYSIWYG，提升了开发体验.

无代码应用程序编译器

我成功地为无代码应用程序开发了一个Rust编译器, 使用户能够以接近本机的速度执行这些应用程序. Through WebSockets, 该应用程序促进了无缝通信, 分析潜在的执行路径并验证应用程序的功能. 它小心翼翼地导航着这些路径, 在虚拟文件系统上生成一个完整的Rust项目, 它后来通过一个二进制接口通过STDIN/STDOUT编译和调用. 利用SIMD和WGPU组件, 编译器擅长对大量数据集进行矩阵计算. 由于我的Rust专业知识，我独自承担了这个项目, 在政府机构的资助下.

无人机任务规划系统

我成功地为一家无人机制造商制作了一个定制的无人机任务规划解决方案. 利用Python并在开源ERP系统Odoo上构建, 客户已经使用了哪些, 我开发了一个能够协调多天的应用程序, 多飞行无人机任务. 每一次任务行动都被细致地记录下来，以确保全面的记录. The application seamlessly interfaced with the drone via an API, providing real-time health data. 它跟踪了无人机从维护到产品开发的所有变化. 无论是测试还是商业飞行，这款应用程序都有助于飞行计划. Furthermore, 它提供了深入的分析, including flight hours, accidents, 对授权进行细致的记录, 对飞行员和无人机都有利.

Notably, 这个解决方案允许客户从Jira过渡过来, streamlining mission planning into a dedicated software that lightened the workload on pilots and ensured compliance with all legal requirements.
