Work History
ML/AI Engineer
Hello Heart
10.2023 - Current
- Developed and deployed two end-to-end production ML models: a risk prediction model for heart conditions and an insights recommendation processor, taking both models from research to production.
- Implemented comprehensive data pipelines using AWS Glue to create Athena tables, and built offline and online feature stores for both training and inference datasets, ensuring efficient data management and model performance.
- Designed and deployed real-time and batch inference systems for both models, setting up robust monitoring and alerting mechanisms to ensure continued model health and performance in production.
- Utilized Python and SQL extensively for data analysis, feature engineering, and model development, while collaborating across teams to integrate ML solutions into the product ecosystem.
Data Scientist
Polygon
07.2022 - 04.2023
- Developed SQL tables and Big-Query datasets which encapsulates users behavior on Polygon network. Utilized the Apriori algorithm to mine association rules and identify patterns among user groups. This led to more effective marketing strategies.
- Developed a system using PySpark and SQL to detect over 98% of arbitrage and liquidation events on the Polygon network, showcasing its effectiveness in capturing significant network activities.
- Ingested and decoded blockchain data from various Ethereum-compatible chains, enriching our data warehouses through SQL table maintenance.
- Oversaw custom research projects in sectors such as Decentralized Finance, Non-Fungible Tokens, and gaming. Created reports and dashboards using Looker and Python.
Data Scientist
SeeTree
10.2019 - 06.2022
- Achieved over 20% improvement in true positive rate for detecting symptoms on trees by training, evaluating, deploying, and maintaining CNN classification models.
- Led the design and implementation of several MLOPS pipelines for data collection, data annotation and dataset building using Python, SQL, Google DataFLow and Apache Beam
- Built an automatic multi camera calibration module using SIFT like features detector and RANSAC to account for outliers. Improved accuracy and robustness of calibration.
Algorithm Developer
Intel, TrueView
09.2017 - 08.2019
- Developed advanced algorithms for computer vision modules, such as segmentation, 3D reconstruction, and calibration, to optimize TrueView's image processing pipeline for efficient performance.
- Achieved over 10% improvement in accuracy for fast-moving objects image segmentation by designing and implementing a high-precision temporal segmentation flow.
- Conducted algorithmic optimizations on a visual hull-based 3D reconstruction algorithm, resulting in significant improvements in accuracy and run-time performance.
