Olivia (Shiqi) Ma

I'm a dedicated Backend Developer and Machine Learning Engineer with a strong academic foundation in computer science. I hold a Bachelor's degree in Computing & Financial Management with Dean's Honors from the University of Waterloo and am about to pursuing a Master's in Computing with a focus on Artificial Intelligence and Machine Learning at Imperial College London.

My professional experience includes designing and building scalable microservices, implementing GraphQL APIs, and optimizing database performance. I'm particularly skilled in AWS infrastructure and automation, having created deployment pipelines and monitoring solutions.

I thrive in dynamic, collaborative environments and have a passion for pushing the boundaries of technology. I'm excited to contribute my skills and knowledge to impactful projects that drive innovation and solve complex problems.

Backend Developer Intern 

Ergoz 

Shanghai, China 

• Developed recommendation system to generate multiple recommendation strategies including exploration, categories and nearby functionalities using Spring Boot for backend services, GraphQL for APIs and Kubernetes utilized by over 1k users 
• Implemented data processing pipeline to gather realtime user interaction data with AWS Kinesis and user profile data, create scheduled jobs to feed the training data to recommendation model every hour using Apache Airflow 
• Connected Grafana to AWS service to track service performance of recommendation system, using over 10 matrix in latency, number of times called and viewership rate of recommended content 
• Designed and developed crawler using Python, AWS Lambda and CloudWatch to schedule crawling content daily from over 90 Instagram accounts and hashtags at specified time 

R&D Intern 

Momenta 

Beijing, China 

• Developed visualization tools for model data and draw activation value heatmap, outputs scatterplot and weights line chart using Matplotlib and Seaborn 
• Used Protocol Buffers in Python to launch model encapsulation, unifying model representations and enabling synchronous modification of serialization and inference logic I
• dentified inference problem of slow speed caused by batch transmission of data on remote platform, introducing batch forward packaging and transmission of data to improve speed by 16 times 
• Implemented CI pipeline in Github for automatic test and deployment to avoid installation and operation issues resulting from platform use in different environments
