      ● Lincoin is the leading North American Bitcoin mining pool changing the game of Bitcoin mining through innovating in pool, firmware and farm level.● Scrapped, cleaned, and unified energy data from nine North American energy providers including ercot, spp, and nyiso with Python. It was challenging because not all of the sources had APIs and the data should have been extracted from the interfaces via parsers like BeautifulSoup and lxml or analyzing network requests. It was a massive success because the company could launch a product based on that.● Parsed and structured the wrangled data with Pandas and NumPy to prevent faults in data sinks.● Provided a backend with Flask to serve the cleaned data into the pipeline.● Integrated and visualized the source data with Grafana to give the C levels and the customers an insight.

      ● WECHANGE is a cooperative of visionaries, developers and many volunteers with a clear goal: to actively promote social change towards a more social and ecological world. ● Collaborated closely with product owners, designers, and backend developers to shape the project in its best form both regarding the user experience and the developer experience. ● Broke down the project into solvable tickets that could be scheduled into Scrum sprints, estimated, and measured in terms of story points. With this policy we could satisfy our promises to the customers and frequently balance the constraints of time, quality, and budget. ● Configured Chackra UI theme to match the platform design language. The challenge was to style the components only via the theme both for the light and dark theme. Also we had the requirement that different portals may have different brand colors and styles. ● Developed various multilingual pages and scenarios including custom flow of authentication, private areas, multi-step forms, stateful components, and reusable layouts.
