...thing I've accomplished is developing a machine learning model for ligand binding to cell GPCR that outperformed the best publicly available model at the time.
Work Experience
Director
Tech-Art
- Made a machine learning model for assigning an expense type based on product descriptions (text) and other features.
- Developed an API using Django with a GraphQL endpoint for administration and data manipulation (CRUD) and a PostgreSQL database.
- Built a utility module for the company's internal use by creating an interface layer on top of standard Python libraries and third-party modules tailored to the specific user needs.
- Made a machine learning model for assigning official product codes to invoice lines based on product descriptions (text).
- Deployed a web scraper to collect, process, and store publically available data into a local database using Selenium, Django, and Postgres.
- Created a script that automates the use of the Docker Machine Amazon EC2 driver. It also creates a new machine, runs the Docker image, stops the machine, and deletes the stack.
Data Science Manager
Ancora
- Developed custom algorithms for extracting clinical trial inclusion and exclusion criteria from free-form text.
- Created a machine learning model for predicting ligand binding to cell GPCR membranes that outperformed the most accurate model publicly available at the time.
- Managed an eight-people distributed team using Agile development techniques.
- Communicated with clients in the requirements definition process.
- Deployed the application's back end to AWS using EC2, RDS, and Route 53.
- Created a short-term ML model for forecasting sales over a vast geographical area with a complex political structure using the DeepAR algorithm.
- Designed a complex data model in the healthcare sector and implemented it in PostgreSQL.
- Provided mentorship and code reviews for junior team members and interns.
Data Science Lead

- Deployed the application's back end to AWS using EC2, RDS, and Route 53.
- Created a long-term forecast model for sales of medication in emerging markets using XGBoost.
- Created a long-term ML model for forecasting sales using Keras.
- Designed a complex data model in the healthcare sector and implemented it in PostgreSQL.
Data Science Analyst
Ancora
- Created a data visualization app using Python (PyQt 5).
- Conducted data analysis using PL/pgSQL and PostgreSQL.
- Applied data parsing and sanitizing using Beautiful Soup and Python re module.
Experience
Ancora
https://www.ancora.ai/My role as a data science manager entailed designing the data model, implementing parts of the NLP process, managing a distributed team, and deploying the app to AWS.
Short-term Sales Forecast
I owned the entire project, from data sanitation and enrichment, feature design, and model training to validation. Used Amazon SageMaker and Amazon Forecast.
