    I am a skilled Power BI custom visual developer. I can use React, d3.js, and Bootstrap to develop custom visuals. The custom visuals have the same functions as those official visuals. Utilities include but not limited to filter, tooltips, and custom format pane. I have three years of working experience in data analysis, with my most recent focus being on financial analytics. In this capacity, I made performance dashboards using Power BI and processed data using SQL and DAX. I started my career working as an auditor in Big Four. My clients are data- intensive organizations, which means the key to this role is understanding and analyzing large amounts of data. By leveraging advanced Excel functions (Pivot Table, VBA, and DAX), I was able to produce results timely and accurately. Apart from that, I used SQL to extract, transform and load data.

    I'm a machine learning Engineer with 3 years of work experience and 2 years of educated background in master's degree. I could implement AI models with a diversity of algorithms, and find AI solutions for business cases. I am a highly self-motivated individual capable of navigating from identifying real-world business challenges to devising optimal solutions, and then proceeding to model training, optimization, and deployment—all accomplished to a high standard. Specialty: LLMs, Machine learning, Deep learning, neural networks both in NLP and CV domain What do I do? - Machine Learning / Deep Learning Models using Python - Natural Language Processing (NLP) / Computer Vision (CV) using Python - Prompt Engineering for ChatGPT / Other LLMs - Data Analytics using Python - Data Science Models using Python Skills: - Programming: Python (Pytorch, TensorFlow, Keras, OpenCV, Pandas, NumPy, SciPy, Scikit-learn, etc), SQL, Shell scripts - Statistical/Machine Learning Models: Retrieval Augmented Generation(RAG), LLM fine tuning, Recommendation Systems, Neural Networks, Prompt Engineering for LLMs, Reinforcement Learning, Imitation Learning, Deep Auto-encoder(DAE), Restricted Boltzmann Machine(RBM), Principal Component Analysis(PCA), Self-attention Mechanism, Regression, Clustering, Decision Tree, Pattern Recognition, etc - NLP Tools: BERT, NLTK, spaCy, GPT - Databases: SQLite, MySQL - Cloud Platforms: Azure, AWS - DevOps Tools: Git, Linux, Docker, CUDA, GPU - Data Visualisation: Power BI, TensorBoard, Matplotlib, Seaborn - API Development and Integration: Postman - Web Development: Flask - Other Tools and Technologies: Carla Simulator Recent projects: - Generating SQL in finance utilizing Large Language Model (LLMs) , Feb 2024 - Jul 2024 Responsible for developing the SQL generation model for a chatbot system, transforming client queries into SQL queries to retrieve and display relevant data from the backend database as numbers or charts. I developed an SQL generation model using LLMs Qwen/Mistral, optimising performance and accuracy with customised prompts, pre-defined rules, and pre-written formulas. - Chat with PDF utilising LLMs, Jul 2023 - Jan 2024 Enhanced the capabilities of LLMs by introducing the "Chat with PDF" feature, enabling users to upload local PDF/txt documents and ask questions based on the document's content. I innovatively introduced a new method where LLMs pre-generate virtual materials needed to answer a question, combine this information with the question, and then calculate the similarity between this combined information and each chunk in the PDF document. Additionally, I initiated a self-assessment feature for LLMs to verify whether the generated answer truly addressed the question. Eventually, response accuracy was improved by 8%, this significantly boosted customer satisfaction and company revenue. - Autonomous driving car with Carla open source, Oct 2021 - Dec 2022 Developed and optimised self-driving AI algorithms with Reinforcement Learning(RL) and Imitation Learning(IL) in Carla Simulator, using images from equipped cameras as input. I implemented RGB image preprocessing techniques, such as Gaussian blur, shadowing, shearing, brightness adjustment, etc, and tested the model not only on regular scenes but also on 10 customised extreme scenarios in Carla Simulator, such as manoeuvring in the opposite direction, an opposite vehicle running a red light, control loss, etc. Eventually, RL and IL were demonstrated functionality in 8 out of 10 assessed scenarios, exceeding client requirements and earning high customer satisfaction. Earlier projects: - Relation extraction with BERT model, May 2021 - Oct 2021 - Anomaly detection with deep neural networks in Aircraft Propulsion, Apr 2020 - Sep 2020 - Speech synthesis from ECoG using Transformer with self-attention mechanism, Sep 2019 - Oct 2020 - Ball kicking module for Nao Robot, Sep 2019 - Jan 2020 - Face recognition with principal component analysis, Feb 2019 - Mar 2019 - Anomaly detection in the early universe, Jan 2019 - Jun 2019 Certification & Awards - Microsoft Power BI Data Analyst Associate (Apr 2023) - Microsoft Azure AI Fundamentals (Nov 2022) - Second place in a self-driving competition with a team of 5 using a 1/16 scale car model, organised by Microsoft (Jul 2022)
