FAQ System that Automatically Generates Answers (NLP): DynamoDB, BERT, Milvus, Boto3, LangChain, Docker•Designed the architecture of the FAQ system and implemented the modularization of system back-end development..•Extracted contents from PDF files by PyPDF2.•Implemented recursive text chunking through Langchain, which solves the problem of individual words left behind in text chunking.•Used BERT's embedding function to convert text data into vector data and uploaded the data to DynamoDB. Released program memory from 2GB to 60MB.•Deployed Vector Database (Milvus) through Docker and extracted DynamoDB's vector data for similarity search. Used cosine similarity to perform similarity search. Provide knowledge base for LLM.

Streaming Media API (MacOS Development): Xcode, UIKit, AVFoundation, Tab Bar Controller, Navigation Bar•Designed the front-end client service by modules with Python and set up key communication channels by TCP/IP.•Delivered refresh speeds of more than 60FPS for video streaming of images sent from the USB-camera through Python server. Built check points to solve the program crash caused by the congestion of receiving data.•Solved the memory leak problem by auto release pool function. Reduced running memory from 1GB to 50MB.•Tested performances of the App and increases the availability and reliability.•Wrote the project report to share the experiences to peers.Image Processing (Python Development): Mask-RCNN, OpenCV, Numpy, Deep Learning•Designed and built parts of the Python server which received image data from our Swift Client by TCP/IP connection.•Participated in the development of identifying and outlining objects. Successfully detected the human faces in the image with over 95% accuracy, by Mask RCNN and OpenCV.•Checked the “IEND”chunk of PNG image and solved the problem that the program cannot automatically load images continuously.Camera Connection App (iOS Development): Xcode, UIKit, AVFoundation, Tab Bar Controller, Navigation Bar•Designed the front-end user interface for the application in UIKit with multiple modules - home page, account information, settings, etc. Connected the application to iPhone camera.•Built the function of displaying images and videos from network, and graft the function to the subsequent reception and storage of camera data.•Built functions of saving image capture and video clips from IP camera in iPhone Library by AVFoundation. Improved App usage efficiency and data preservation.
