My background is in data mining and machine learning with applied research experience working at the Data Mining Lab, York University. My most recent experience was working as an MLOps Engineer at a Google Cloud Platform (GCP) consulting company where I leveraged GCP ML stack to deliver end-to-end machine learning models. I’m certified as a GCP Professional Machine Learning Engineer.
I have experience working with Geo-Spatial Data sets for which I used PostgreSQL & PostGIS and Python to extract insights. I typically visualize data sets along the way to understand the pipelines and models I’m creating.
I conducted research as an Erasmus Scholar @ the Department of Information Technology, Uppsala University, Sweden in the area of Cloud Computing.
During my graduate studies at York University, I was working under the supervision of Prof. Manos Papagelis.

Graduate Research Assistant
Jan 2018 - Apr 2020
• The research was related to trajectory data mining, machine learning, and statistical inference.
• Developed a method that utilizes trajectories of [cars, pedestrians, etc.] as a way to infer semantic similarities between geographical areas.
• Published the research titled Learning Semantic Relationships of Geographical Areas based on Trajectories at the IEEE Mobile Data Management Conference 2020 Versailles, France, and received Best Paper Award.
Swedish National Infrastructure for Computing, Uppsala University
Aug 2015 - Jan 2016
• Designed a framework inside SNIC using Apache Spark, SparkR & Jupyter Notebook to simplify computations of highly parallel scientific applications.
• Our project titled Towards Moving Scientific Applications in the Cloud enabled researchers to seamlessly deploy their applications on the spark server and scale it to multiple worker nodes as needed.
Learning Semantic Relationships of Geographical Areas based on Trajectorieshttps://github.com/saimmehmood/semantic_relationships
Python (networkx, pandas, numpy, seaborn, matplotlib), PostgreSQL, PostGIS, MATLAB, Google Cloud (Places & Directions) API
• Developed a framework to understand semantic relationships between geographical areas based on object movement paths i.e., trajectories. (Best Paper Award for IEEE Conference on Mobile Data Management 2020)
Expert Developer Recommendation Using Very Large Datasetshttps://github.com/saimmehmood/ExpertDeveloperRecommendation
SQL, Google BigQuery, Elasticsearch
• Built a search engine to find expert developers by utilizing GitHub datasets. • Reduced 3TB of data into merely 600 MB by keeping developer specific information such as (number of commits, first and last commit, average time between commits etc.)
Towards Moving Scientific Applications in the Cloudhttps://github.com/saimmehmood/Towards-Moving-Scientific-Applications-in-the-Cloud
Cloud Computing, OpenStack, Apache Spark, Jupyter Notebook
• Cloud computing provides usability, scalability and on demand availability of computational and storage resources, remotely. These are the characteristics required by scientific applications and that’s why we used it. The project had two dimensions. First one addresses the benefits of cloud infrastructure for end users. In the second portion, we tried to do performance analysis.
