Do you want to build very powerful data science applications with stunning visualizations? Or are you interested in obtaining data from the web, it could be huge amount of data that would take more time to obtain manually. Or even more, do you have messy data, that is unstructured and you want that data to be cleaned, analyzed, modeled and visualized? Well, I'm here for you. I'm a passionate data scientist, web scraping and automation expert who offers optimum solutions to all of the above stated challenges. My day to day basis revolves around data. Right from data extraction and web scraping to data cleaning, data manipulation, data mining and analysis all the way to data visualization is just a general picture of what I do. 🔸🔸🔸𝙃𝙀𝙍𝙀 𝙄𝙎 𝙒𝙃𝘼𝙏 𝙄 𝘾𝘼𝙉 𝘿𝙊 𝙁𝙊𝙍 𝙔𝙊𝙐 ✅ Web Scraping and Data Extraction - being a passionate data extraction specialist, I tend to give web scraping a little more attention because I am keen to obtain the right data, with more accuracy and correctness. I build web scraping tools that update data to a database regularly. ✅ Data Cleaning and Manipulation – sometimes data is messy and not well structured. My attention to details ensures that data is clean and manipulated well before analysis. ✅ Exploratory Data Analysis – the building of models depend on insights derived from the data. Using EDA, I'm able to derive insights that go along way in determining what data decisions we take. ✅ Data Mining – this ensures that I extract vital information from a large dataset and thus find out the patterns and correlations between several business variables, which is very useful to any business. ✅ Data visualization - a great analysis would be useless without it being visually presented to users. I harness the power of Python visualization libraries as well as Google Data Studio and PowerBI to come up with stunning visualization charts and dashboards, that are able to easily communicate to the users. ✅ Machine Learning - I also build powerful machine learning models that are very useful for businesses. Models that can accurately predict stock prices, weather, real estate prices etc. ✅ Spatial Analysis and Remote Sensing – as a spatial analyst, I have built tools around network analysis, geocoding and geolocation, suitability analysis, least cost path analysis, route optimization, isochrones analysis, demographic analysis. Using tools such as ArcGIS, QGIS and GEE, I'm also able to handle satellite image extraction and processing, DEM processing and image classification. 🔸🔸🔸 𝙎𝘼𝙈𝙋𝙇 𝙀 𝙒𝙀𝘽 𝙎𝘾𝙍𝘼𝙋𝙄𝙉𝙂 𝙋𝙍𝙊𝙅𝙀𝘾𝙏𝙎 1. Scraping football matches for odds across different betting websites - this tools scrapes for betting odds every 15 minutes from different betting websites and stores the data in Google Sheets. 2. Scraping E-Commerce Products - this project harnessed the power of web scraping to obtain the details of certain products, which included prices, discounts, ratings, product features etc. I utilized this simple project when I was purchasing my new phone, where I let the tool assist me in finding the cheapest deal of a specific phone from a range of shops. 3. Scraping Movies' Website – this was a side project where I was obtaining movie information from a movie website. Information on the movies, such as genre, movie title, year releases, ratings, trailer links, reviews etc. were all modeled to try and build a recommendation system. 4. Scraping Stock Market Sites – this was a project where I was helping a client to obtain market stock prices on some of the stocks: Bitcoin, Gold, S&P 500 etc. What makes this a unique project is that it automatically runs on a daily basis to extract the changing prices. This process is automated to be a recurring task. 🔸🔸🔸 𝙊𝙏𝙃𝙀𝙍 𝙋𝙍𝙊𝙅𝙀𝘾𝙏𝙎 𝙄 𝙃𝘼𝙑𝙀 𝘿𝙊𝙉𝙀 ✅ Building PowerBI dashboards and reports aimed at visually presenting data. ✅ Modeling schools data and building visualization dashboards to help track, monitor students and their scores as well as allocate teachers across schools. ✅ Calculating travel time to different schools to find accessibility range. ✅ Building route optimization algorithms. ✅ Developing a stock comparison chart for different stocks/assets. ✅ Building a planting calendar dashboard using Google Data Studio. ✅ Building a forest fire dashboard to help in fire analysis, analyzing trends and predicting occurrences of such phenomena. ✅ Developing GIS mapping applications and geo-processing tools. . 🔸🔸🔸 𝙒𝙝𝙮 𝙈𝙚? ✅ Attention to details. ✅ Sharp suggestions that help improve project success. ✅ Great commitment. ✅ Fast response and good communication. ✅ Self-driven. ✅ Reliability.
