Aerospace control engineer building fitness, autonomy, and quantitative tools from Germany. 航空航天控制工程背景，正在德国做健身软件、自主系统和量化学习相关的个人项目。
I studied aerospace engineering at the University of Stuttgart and worked on flight dynamics, control allocation, distributed electric propulsion, PX4 firmware, ROS2/Gazebo simulation, and learning-based aerial robotics. My current work connects that engineering background with personal software products, fitness systems, and quantitative finance learning. 我在斯图加特大学学习航空航天工程，做过飞行动力学、控制分配、分布式电推进、PX4 固件、 ROS2/Gazebo 仿真和学习型空中机器人。现在我把这些工程经验延伸到个人软件产品、健身系统和量化金融学习里。
A Flutter-based strength training and nutrition tracker for serious lifters and coaches. It includes structured plans, workout history, nutrition logging, Supabase sync, multilingual UI, and a coach SaaS workflow moving toward a desktop web dashboard. The product is still pre-customer and being shaped through personal use, technical validation, and demo workflows. 力量训练与营养追踪应用，包含训练计划、历史记录、营养日志、Supabase 同步、多语言界面和教练 SaaS 工作流。现在还没有真实客户，仍处在个人使用、技术验证和演示流程打磨阶段。
Product in validationNavigation, guidance, control, NMPC, control allocation, PX4 integration, ROS2 simulation, and flight software work for fixed-wing, multirotor, lighter-than-air, and current FPV/autonomous drone simulation work. 固定翼、多旋翼和飞艇方向的导航、制导、控制、NMPC、控制分配、PX4 集成和 ROS2 仿真；现在的 FPV/自主无人机小项目还在 DroneSim 仿真阶段。
AerospaceOngoing study notes and models around quantitative finance, risk, derivatives, and systematic analysis. This will later become a cleaner public reading log instead of a raw file dump. 正在系统学习量化金融、风险、衍生品和系统化分析，后续会整理成更清晰的公开学习记录。
Learning logIronTrack started as a replacement for spreadsheet-based gym tracking and is growing toward a coach workflow: plan assignment, nutrition targets, review states, and eventually a desktop dashboard. It does not have customers yet. IronTrack 从替代 Excel 健身记录开始，逐步扩展到教练工作流：训练计划分配、营养目标、复盘状态和桌面端看板。目前还没有真实客户。
This is a future product experiment, not an active offer yet. For now it stays here as a visual note: a playful fitness accessory that may later become a small Germany-based listing after product, price, logistics, and legal details are decided. 这是之后可能慢慢做的小商品实验，目前不是正式销售页面。先作为视觉占位，等产品、价格、物流和合规细节都确定后再决定是否上线。
Current focus: web-safe Flutter entry point, Supabase auth, real coach data, and clean deployment.当前重点：Flutter Web 入口、Supabase 登录、真实教练数据和部署。
Topics include derivatives, risk, models, and systematic analysis. Public notes will be curated later.正在整理衍生品、风险、模型和系统化分析相关学习材料。
The current stage is still DroneSim simulation. I plan to add my own FPV photos later when the hardware side is ready.目前还在 DroneSim 仿真阶段。等硬件侧准备好后，我会补上自己拍的 FPV 照片。
