Hello! I'm a python developer who's experienced in data mining, machine learning and statistics. I can get you insights and informative visualizations, or transform the data you have to the data you need. I work with startups, entrepreneurs and small businesses to get them quality results quickly. I'm friendly and easy to work with, and I provide quality customer service every time. Contact me today! I can solve your problem, quickly. Machine Learning: I've used ML to solve touch problems and deliver quality work. Together with my degree in Statistics I'm well-equipped to derive insights from large challenging datasets. Data Mining: I'm skilled in extracting and transforming data to meet your needs and surface insights. I have experience with tools like numpy, pandas, PostgreSQL and formal grammars, and I get results. ETL: Working from an SQL database, JSON file, XML file or spreadsheet, I can load the data, clean it up or transform it, and output it in any format. I turn in highly polished results, every time. API Integration: I'm also to download or upload data from APIs, implement API integration, or maintain state in a remote system via an API. Even the hard-to-work-with ones. Not much slows me down.

Over the last 7 years, I have developed a wide range of websites using HTML, WordPress, PHP and MySQL including sites for startup companies and small businesses. I have customized SugarCRM to meet various workflows. Also created many upgrade-safe custom modules for SugarCRM. I can customize SugarCRM not only in an upgrade-safe manner, but also tinker with the core functionality to meet any specifications. Since SuiteCRM is a fork of SugarCRM Community Edition and uses its codebase, I can (and have) work on it as well. Software Documentation - Requirements - Client Communication(Interview) - Team Orientation - BRS / SDS - Project Manuals - Wireframing - Diagram (DFD , Pageflow diagram etc) - Requirement Prioritization Project Management - Client Communication - Task Allocation - Resource Management - Scrum Master - JIRA, Trello, VersionOne less
