  Fine-tuned a pre-trained model (BERT) to perform sentiment analysis on noisy structured data. Created a preprocessing pipeline to clean the noisy data. Prepared a text labelling guideline for local teams to label the data accordingly. Performed data clustering on noisy text data to assist a slot-filling task. Analysed text data to find the optimum amount of clusters using mathematical methods. Experimented on different word/sentence embeddings (e.g. BERT embedding, fastText embedding, word2vec, GloVe, TF-IDF) to compare the weaknesses and strengths in different tasks of NLP. Researched on different python web frameworks to find one that suits the application. Developed and deployed APIs using falcon web framework which consistently performs really well on high load. Crawled data from online sources using multiprocessing on multiple proxies while maintaining low number of HTTP request to prevent web traffic disruption. Performed unit testing (Python's unittest and PyTest) and load testing (JMeter) on APIs before entering UAT and Live deployment. Application of various machine learning algorithms, statistical modelling and evaluation metrics using scikit-learn. Show less

  Developed a dashboard web application with ASP.NET MVC and ASP.NET WebAPI as a CRM software. Deployed the web application to IIS Server. Researched on machine learning use cases in telecommunication company. Introduced to Speech-to-Text Conversion by Google and discussed with manager about my findings. Created an application to convert .wav file into binary data, which enables voice data storage. Learned different attributes in a .wav file (encoding, sample rates) and compression techniques (lossless and lossy compression). Show less
