Tech lead on the Square Measurement Science team. The team is responsible for all forecasted internal metrics that are utilized from multiple teams across Square for quarterly/annual planning and investment portfolio optimization.
- Consulted on the design & development of various projects within the team. Helped by identifying possible gaps/roadblocks and suggesting ways on how to overcome these risks.
- Formed a small independent team of MLE's within Square and contributed to the design and implementation of a framework for deploying trained ML models as a service. The framework facilitated the application of ML models where real-time scoring was necessary.
- Enhanced existing merchant value forecast models to take into account the observed effects as well as speculated effects of the COVID-19 pandemic.
- Built a framework that facilitates the training of predictive models that are used to forecast a merchant's value across various Square products.
- Improved merchant churn prediction model, significantly decreasing the false positive rate in the upper score range. This in turn increased the amount of relevant case generation for the merchant retention program, meaning an ~ $11,000 improvement in daily ROI.

Research conducted at Square Capital for the purpose of automatically suggesting solutions to customer email inquiries. The research yielded a novel deep learning architecture that combines two disparate data sources when estimating its predictions.
Deep Learning in Customer Churn Prediction: Unsupervised Feature Learning on Abstract, Company Independent Vectors
Jun, 2015 - Aug, 2015
Initial research performed for Framed Data as part of the MSc Data Science Degree dissertation at Lancaster University. The research work conducted proved that Deep Learning can be successfully applied in the field of customer churn prediction by yielding better prediction results while also bypassing the tedious feature engineering phase in a traditional machine learning pipeline.

Resume Writing Tips
The following tips are based on what we've learned from helping over 100,000 job seekers create a resume with our resume builder.
Resume Format and Sections
Impressing recruiters and hiring managers will be much easier if you include the info they are looking for, in the correct order. Here are the sections and order we recommend.
- Contact information: This should be at the top of your resume and easy to find. Make sure to include your email and phone number.
- Work experience section: This is the most important part of your resume. Focus on your work experience that is most relevant to the job description you're applying for and use short bullet points.
- Education section: Make sure to list any degrees or certificates that the job posting requests. Only include your GPA and courses if you're applying for entry-level jobs.
- Other sections: You can also include skills, languages, patents, side projects, etc if they are relevant to the job you're applying for. It's generally best to avoid references. Recruiters will ask for them later and they take up valuable space.
While the contents of your resume are undoubtedly the most important part, a good resume template can increase your odds of getting an interview. Most requiters only spend a few seconds on their initial resume scan, you need to make them count.
If the job application requires a cover letter, it should have similar formatting to your resume.
Data Scientist Skills
Skills are an important part of a data science resume. You should analyze the job description you're applying for and make sure to include the requested skills in your work experience and skills sections. Focus on technical skills and omit soft skills like "problem solving". Recruiters ignore them.
Here are some skills that are frequently included in data science job descriptions on our remote job board.
- Machine learning
- Big data
- Data sets
- Data management
- Data processing
- Data modeling
- Random forest
- Large data sets
- Microsoft Azure
- Amazon web services (AWS)
