Work Experience
Senior Machine Learning Engineer
Adidas
- Developed a temporal fusion transformer model for demand prediction, which decreased mean absolute error by 10% compared to a linear model.
- Implemented Bayesian hyperparameters optimization and distributed learning with Amazon SageMaker and PyTorch Lightning.
- Designed and developed an ETL pipeline for pricing models using PySpark and Airflow. Implemented CI, unit, integration, and data quality testing.
- Implemented simulation based markdown optimization algorithms.
Machine Learning Engineer | Co-founder
Solai Inc.
- Outperformed traditional approaches by 5-20% by researching and developing deep reinforcement learning algorithms for solving the vehicle routing problem (VRP), including creating a discrete event simulator for pickup and delivery issues.
- Designed and developed a transportation management system back-end API with Go Fiber and PostGIS and implemented a CI/CD pipeline with GitHub Actions.
- Reduced expenses by 60% by developing and training models using XGBoost and graph neural networks to lessen distance matrix API requests. Used Amazon Sagemaker to implement the ETL and training pipeline.
- Improved on-time delivery from 50 to 90% and reduced average delivery time from 70 to 50 minutes by designing and creating a simulated annealing-based real-time dispatcher for on-demand grocery delivery. Built XGBoost-based models for ETA prediction.
- Researched and developed meta-heuristic algorithms to solve various black-box optimization problems. Configured and implemented VRP and linear programming solvers such as jsprit, VROOM, OR-Tools, LKH-3, Gurobi, and CP-SAT.
Machine Learning Engineer
Aitu
- Designed and developed the ETL pipeline for a video-sharing platform's recommendation system.
- Increased the click-through rate from 4 to 6% by developing collaborative filtering and content-based recommendation systems in an A/B testing environment.
- Developed a deep convolutional model for detecting not-safe-for-work content.
Machine Learning Engineer
PUBG (trademarked by KRAFTON)
- Created an image classification model and a weakly supervised object localization model to detect extra sensory perception cheat occurrences on users' gameplay screenshots—achieving 95% accuracy and above 0.5 Intersection over Union value.
- Developed a time series classification model for auto-aim and recoil-control cheating detection—achieving 80% recall and 95% precision on the unbalanced dataset.
- Handled the logic design, data analysis, and development of the behavior tree for a data-driven AI bot for PUBG PC and console—outperforming the previous bot and replacing it in later updates.
