The most amazing...
...project I've developed is building a custom trial optimization model for a pharmaceutical company which outperformed all existing ML models.
Work Experience
Senior Data Scientist
Novo Nordisk
- Built time series forecasting models using SOTA deep learning algorithms like N-HiTS and N-BEATS, which outperformed traditional ARIMA and Holt-Winters ES models.
- Built a proprietary trial optimization algorithm to predict the end date of trials, which outperformed all the time series models.
- Built ensemble models for demand and sales forecasting.
Machine Learning Developer
Zvoid
- Created a tweet listener capable of listening to the tweets from a given list of authors and making the data ready for the decision engine.
- Built the automated trading capacity using the Alpaca API.
- Developed the end-end analysis of a particular Twitter IPO hypothesis.
- Worked on the decision engine using a random forest regressor that accepts the tweet and the stock price and gives out a stock buying or selling recommendation.
Senior Data Scientist
COGNIZER AI
- Developed a BERT-based conversational AI solution based on business requirements.
- Converted natural language queries into SQL queries using BERT-based deep-learning architecture.
- Contributed to significant parts of the back-end flow and took ownership of those flows.
- Extracted various fields from contract PDFs using regex and deep learning models and optimized the models to increase processing speed using TensorRT.
- Put the DL models into production using APIs and Docker. Used AWS and GCP to enable autoscaling features.
Data Scientist | Researcher
Freelance
- Built data pipelines for data coming from multiple sources like the Quandl API and a SQL database.
- Performed an exploratory data analysis on the built dataset, derived insights, and presented it to the stakeholders on Jupyter Notebook and Tableau.
- Modeled the data using decision tree-based regression models.
CTO
WiseLike
- Competed at the IE Business School's startup lab and won the investors' choice award and the most innovative project award.
- Developed the whole machine learning pipeline from scratch, starting with a web scraper for pictures, extracting properties of a picture, and training the model using the data.
- Served the model using a REST API (Flask) on the website wiselike.pythonanywhere.com.
- Performed A/B and hypothesis testing to test the validity of the model.
Quantitative Analyst
Futures First
- Performed an exploratory data analysis on large-scale financial datasets and derived insights that led to tradable strategies, using Python and visualizing data through dashboards in Tableau.
- Implemented a time series analysis (SARIMA and GARCH) of prices in commodity markets, considering CFTC reports and external factors like currency.
- Developed regression-based mean-reverting strategies in fixed-income markets of the US and Brazil.
- Deployed ETL pipelines and ML pipelines working on GCP.
- Performed backtesting and forward testing of strategies by tracking their Sharpe ratios.
- Performed hypothesis testing and evaluated the risk for strategies based on Monte Carlo simulations and historical value at risk.
- Built natural language pipelines to track news sentiment.
Research Intern
Next Sapiens
- Developed a novel 4D (degrees of freedom) solution for the simultaneous localization and mapping of an unmanned aerial vehicle to reduce the computation cost and published research on the same (Leeexplore.ieee.org/document/6461785).
- Combined location data from various sources like LIDAR, proximity sensors, inertial measurement units, and camera using extended Kalman filters to update the state information of the robot.
- Developed a fuzzy logic-based PID controller for the unmanned aerial vehicle to maintain stability during flight.
