Hello, With a Computer Science degree I Started coding as a Ruby on Rails full-stack developer in 2015. Since then, I've been of building and utilizing APIs, designing SQL databases, creating tests, deploying, and using popular JavaScript frameworks. In addition to my technical accomplishments, I take immense pride in my contributions to the open-source community. Collaborating with fellow developers has been an enriching experience that expanded my horizons. However, beyond the lines of code and the algorithms, my true strength lies in my profound understanding of user requirements. I believe that the heart of software development is in crafting solutions that not only meet technical benchmarks but also resonate deeply with the end-users' needs and aspirations.

Hi, I'm Jarrett. I'm a data extraction specialist and data scientist with 5+ years of experience that includes pulling data and making sense of it for startups. See my website (jdevereaux.com) for examples. I'm certified to work with AWS services to carry out data engineering tasks, and I'm currently working with Bedrock/LLMs and Sagemaker AI. I primarily work with Python, SQL, AWS, and Javascript. I run Linux every day so I'm familiar with server-side operations and cloud deployment. I've engineered, published, and marketed extensions on the Chrome Webstore that deal with automation. My areas of expertise and services offered are: Data Extraction Services: * Make requests to RESTful APIs to retrieve data * Parse through JSON backends | Useful loophole to rapidly pull data from Soundcloud and Upwork * Spoof auth tokens/cookies to get access to data | Useful for sites that require credentials * Use browser automation to keep cookies/tokens fresh | Useful for tasks where you need to maintain account logins * Proxy rotation | Useful as a last resort to get around anti-scraping mechanisms Data Wrangling Services: * Arrange data into an easily navigable file structure * Clean data, drop duplicates, conditionally remove entries, add a column from another source * Update data | Keep track of new entries and update existing rows. Server Side Services: * Deploy projects to cloud * Docker * Creating a RESTful API In my experience, I've learned that good data doesn't come easy. I have some tricks up my sleeve to get past bot detection / CAPTCHAs. There's a lot of good resources on Github that are helpful in my daily stack. I'll be happy to see if I'm the right fit for your projects. If not, I can hopefully point you in the right direction! Thanks Jarrett FAQs - What language do you use? • Python • Javascript - Where can I see some examples of work you've done? • jdevereaux.com • Github (github.com/jarrettdev) • Kaggle (kaggle.com/dataranch) • LinkedIn [linkedin.com/in/jarrett-devereaux-75846a323/ - What libraries do you use? + Sending GET/POST requests • Requests • Axios • Scrapy + Parsing webpages • Scrapy • BeautifulSoup • json + Bypassing CAPTCHAs • Puppeteer-Extra + Proxy rotation • Torchestrator + Data cleaning / wrangling • Pandas + Data visualization • Matplotlib • Seaborn
