• Because of the stealth nature of the project, I do not disclose the goal and scope of the project. I function as a foundation engineer to probe the design, technical viability, and construct a POC of a complete AI based software. Here are some of the tech skills that I use in this project:• Investigated various installations of openpose, mediapipe, Yolov8, Yolo-nas, under a variety of environments: Linux, Windows, docker images and containers, Dockerfile, pre-configured images, cmake, python virtual environ, Nvidia gpu, cuda, anaconda, vlc, ffmpeg, streamlit• Used vision ML packages (object recognition, pose estimation) yolov8, yolo-nas, openpose, mediapipe, pytorch for object detection and pose estimation.• Used vision package opencv• Used pretrained models and done some model training. Used annotation software cvat to prepare labels for training.• Done affine transformations for 3D modeling: translation, rotation, quaternions, 3D transformation matrices, etc.• Used Blender to craft 3D objects and Blender scripting (python) for object movement control.• Used Unity and Unity scripting (C#)• Done socket programming for messaging: both UPD and TCP sockets, message between (1) python and python (in Blender) and (2) python and C# (in Unity)• Thread and aync coding (C#) for decoupling messaging and object control• Investigated data storage for storing and searching large amount of image data

1. Done analysis to optimize marketing campaigns parameters (presto SQL/Hive/notebooks).Details: initially to analyze the effect of bid cap, through investigation in database. Bid Cap is one of the ad parameters. During investigation, I found that many other parameters affect the campaign effect, and can be formulated as a high dimensional optimization problem. Used python plotting libraries, presto SQL, Hive.2. Analyzed Marketing result and write report of findings (presto SQL/Hive/statistics/notebooks)Details: marketing campaigns are conducted as A/B test. The results of campaigns are recorded in database. Need to find lift, reach, impression, CTR, OR, in different channels, objectives, and verticals, partner conditions, etc. Any significant discovery need to be backed by statistical significance. This analysis uses z-test, t-test, p-value, winsorization, CUPED, programmed in python/R/Presto SQL on Jupyter style platform) for marketing managers.3. Machine Learning: define audience for marketing campaigns（ML/AI, used PyTorch/Hive/notebooks）Details: based on marketing manager’s marketing campaign design, use ML (PyTorch) to identify target customers suitable to be included in the campaign. This involves label (target measurement of optimization) design, data preparation, model design, and training. The trained models are used to filter customers that are most responsive to the marketing campaign.4. Wrote Data pipelines to support marketing campaigns (Presto SQL/Hive/Python/pipelines).Details: A pipeline (in META) is a python program that combines multiple SQL statements in a logical way, each SQL is in Presto (a big data query engine) SQL and run on Hive data store. The work involves run presto SQL queries on Hive (the effect of presto SQL needs to accomplish what are specified in the marketing campaign design document, from marketing managers), and then combine the SQLs into a data pipeline, and schedule the pipeline run.

Work as a senior technical member in data solution team, with diverse duties and tasks• Data Mining (Text Data Pattern Matching and Apriori): Independently built a program to find more than 1000 useful patterns with over 99% accuracy in a database. To compare, previously, two analysts worked over 6 months and found 700 patterns with similar data. • Text Data Classification: Independently built a program to classify product tier in a database with product info. This program replaced previous manual work. The effect of a single run is equivalent of two-people performing 12-months of manual work.• Text Parsing: Independently built a program to parse US Patent Office PDF documents (>50K docs) to do OCR and extract relevant patent citations information with 95-97% accuracy. These docs are prepared by USPTO patent examiners individually and manually. OCR is the first step in this data processing pipeline.• Data Search Tool: Independently built a MS SQL database search tool with a Windows GUI (PyQt, python). It can be used to visually search and display aspects of a relational database, such as table relationships, relevant keywords, data contents, etc.• Graph Data Visualization: Built a visual interface to display lines & nodes representing graph data in a SQL Graph database.Coding work are python coding with PyQt (GUI), D3 Js (Web node graph), tesseract (OCR), re, nlp, apriori (data mining), relational modeling and graph data modeling
