Data Engineer (Paid Internship). Refactored and improved PGM Click model logic along with Query Reformulation candidate extraction on Hadoop Ecosystem.
- Customisation of Apache Airflow for Working Group
- PGM click model logic refactoring and improvement with Scala-Spark on Hadoop Ecosystem. Hyper-parameter tuning for all PGM models with grid-search. Pipelined and scheduled the model training daily with Airflow (train the model on spark cluster with data from hdfs).
- Built Universal Retrieval Feature Experiment demo tool (For in-house purposes.)
- CLI plugin built for convenience and improvement of in-house retrieval feature evaluation web page (GUI). Presented the plugin at the in-house Engineering Day conference.
- Extracted Query Reformulation (QR) candidates with cross attention score of sentence BERT embeddings. Pipelined and scheduled the extraction by calling the pytorch model deployed on Kubernetes from spark cluster and storing on hdfs

Software Engineer Intern. Built admin tool as webpage for manage search results and engineered features to improve search engine's rank model.
- Front-End(FE) build with Vue.js for Internal Admin page. The Back-End(BE) of the page is built by senior-engineer. By cooperating with others for developing one product (FE-BE) led me to understand the importance of communication with colleague and documenting the clear endpoint. This project guided me to have interest on Full-stack developing.
- Feature Engineering for video search engine's rank model. To improve the performance of established rank model, more than 100 features about the video that were not used are analysed and processed. The engineered features improved Normalized Discounted Cumulative Gain (NDCG) of rank model and also the precision and recall. The ordinary Machine-learning methods are also important as much as how deep-learning works.

Maintenance of hardware(HW) and software(SW) content for Kids cafe / Construction of multiple kiosks for new branch open.
- Supporting maintenance process of old kiosks.
- Maintenance/modification/full-change of HW kiosk due to new application development. Experienced on following machines for parts production. (CNC milling machine, vertical/horizontal milling machine, 3D printer, table save and some handy machines) For CNC milling machine and 3D printer, I had experience of designing part of large parts/whole part of small parts with Autodesk Fusion360.
- Proposed and applied the method for HW and SW maintenance and improvement.
- Application and calibration of sensors and cameras for each kiosk. Most of kiosks had static focus camera so the camera was installed to plastic block which is going to be implanted to the kiosk and the camera is calibrated.
