Jiajing Fang | Software Developer

Hi, I'm Jiajing Fang.

A

Quick learner, passionate programmer who enjoys solving complex and challenging real-world technical problems. Focus on Machine Learning and GenAI area.

I am currently working at DeliveryHero as Backend SDE with skills in Golang, Python, MongoDB, Postgre, GCP, terraform, k8s.

About

I gained my computer science master degree at Saarland University, Germany. I enjoy problem-solving and coding. I am interested in NLG and machine learning area. I have worked on technologies like front-end development (HTML5, CSS, JavaScript), data mining and natural language processing and generation(SpaCy, NLTK, Neo4j) during my study. I have two full-time internship experiences which helped me strengthen my experience in software development and machine learning(NumPy, Pandas, Sklearn, Pytorch, Keras) in QuantPi and Huawei. I am passionate about developing applications for real-world use and researching on up-to-date machine learning.

Languages: Python, Golang, C++, HTML/CSS, Bash
Databases: Postgre, MongoDB, MySQL, Neo4j
ML Libraries: NumPy, Pandas, Sklearn, SpaCy, NLTK,
ML Frameworks: PyTorch, Keras
Tools & Technologies: Git

Always looking for an opportunity to work in a challenging position combining my skills in AI/ML Engineering and Software Engineering, which provides professional development, interesting experiences and personal growth.
