Sebastian Cherny

• Worked as an independent freelancer in different full-stack projects, using React+JS for frontend, Python+Django for backend, and PostgreSQL for storage. Publishing projects in Heroku or through AWS. Docker for CI/CD.
• TDD with unittest, pytest, Selenium and mocks.
• LLM integration via GPT and Claude APIs.

Built projects for several clients:

• Web dashboard for users to register/log in and upload personal information and data that they wanted to analyze, from which a set of interactive graphs would be created and displayed.
• Web dashboard that pulls information from different APIs about Solar Energy production and display graphs, considering a selected timeframe.
• Scrapper for obtaining data from PDF reports and storing it into a database, together with a frontend where the user can search for some of the obtained data and filter it.

In all of these projects I was in charge of building the frontend or APIs from scratch, deploying them in a production environment, test the code and any new change, and build a way so that maintenance would be easy for my non-developers clients.

• Creation and maintenance of websites of internal use, where users can generate Spreadsheets with reports, edit and share them through Google Drive with different users/revisors and mark them as completed, generating automatic changes in the database.
• Administration of automatic checks that daily evaluate and look for errors in the database, reporting them if found; analysis of logging in the AWS servers to detect failures.

Job interrumpted in two periods to participate in Meta's internships.
