# Ivachev Fedor (费杰)
## Self-Introduction
* I am a PhD candidate in Computer Science at Tsinghua University, focusing on **Human-Computer Interaction** — specifically context-aware conversational systems based on real-world scenarios.
* I have accumulated engineering experience at international tech companies such as Huawei and Samsung, with full-stack capabilities ranging from low-level algorithm development to the deployment of large language model applications, covering **Computer Vision**, **Mixed Reality**, and **AIoT**.
* Trilingual (English/Chinese/Russian), I am committed to promoting innovative applications of AI in diverse scenarios.
## Work Experience
#### Tsinghua University, Beijing (Teaching Assistant, 2021/01 - 2022/01)
* Assisted lead instructor in facilitating the Human-Computer Interaction course.
* Helped and taught both international and local students.
* Developed educational tutorials and provided assistance for student group projects.
#### Huawei Technologies Co., Ltd, Moscow (Software Engineer, 2019/02 - 2019/08)
* Worked on low-level graphic profiling tools using **C++**.
* Retrieved data from integrated GPU counters for more precise draw call timing.
* These tools were used by graphic optimization and QA teams.
* Coordinated with developers across Russia and China.
#### Samsung RC, Ltd, Moscow (Intern, Programmer, 2018/06 - 2018/09)
* Developed computer vision algorithms for the 3D Avatar team using **C++** and **Python**.
* Modified OpenCV source code to correct camera distortion and implemented facial physical landmark detection.
* The solution was later integrated into the operating system release.
## Education
* PhD in Computer Science (2021/09-2026/07), Tsinghua University, China. All coursework completed. From 2026/05, taking 1-3+ years leave due to family reasons; will require approximately 3 months leave for PhD defense upon return.
* Master's in Computer Science (2019/09-2021/06), GPA 3.9, Tsinghua University, China
* Bachelor's in Computer Science (2015/09-2019/06), Lomonosov Moscow State University, Russia
## Projects & Technology Stack
* **OpenAI API + Azure AI + Huawei Mobile Services** — AI real-world agent: an LLM-based agent that uses multimodal information from sensors to build comprehensive human portraits and manage real-world contextual conversations.
* **Unity C# + IoT platforms** — [NUIX-Studio APP](https://github.com/FedorIvachev/NUIX-Studio-APP): a platform to test AIoT environments in VR. Based on Microsoft MRTK, OpenHAB, and HomeAssistant (v1), it lets users extend real-world IoT devices with VR functionality. Version 2 uses Oculus SDK and includes a UI for prototyping IoT interactions without programming knowledge.
* **Blender** — TikTok effects: I created 10 advanced AR effects for TikTok (Douyin), used over 3 million times.
