About Coco Lam

Analyzing transportation data is captivating!Data is a root of decision-making which I used for my final year project to analyze bus data to improve the traffic system. I enjoy looking for hidden patterns as well as analyzing the facts behind new machine learning algorithms until the sunrise comes. Comparing the difference between random forest and XGBoost can understand why we use these methods to handle different cases. Now, my work after work-off is to play along with data, training them and optimizing them.With5+ years of experience in specialized in transportation industry and enthused LINUX, SQL, Excel & Python, I love to take the initiative to minimize the processing time of repetitive work by writing scripts. Investigating the usual problems and turning them into code makes me indulge in the world of trying and running the scripts. When I run the results successfully, I feel satisfactory and energetic to brainstorm more innovative ideas and share insights into business solutions with my teammates.As an analytical problem-solver, I am well-versed in data cleaning and debugging complex errors methodically.- OS: LINUX (Ubuntu, Debian, Centos), - Language: SQL, Python (scikit-learn, matplotlib, pandas, numpy), Excel VBA, Bash Shell Script, C++, PowerShell, Node.js, PHP, HTML, CSS, GIT-Tools: Power BI, Microsoft Office Excel, MATLAB, Anaconda (Jupyter & Spyder), Github, JIRA
