Alfie Renn

Software Engineer & Web Designer

Hi! I'm Alfie: physics graduate, toki pona speaker, and software engineer. I love to make beautiful things with code (mainly using HTML/CSS/JavaScript and Python), including websites, apps, and graphs. With all my work I create good quality, robust, and well-tested code, as well as powerful automation and well-organised git repositories, empowering collaboration. Do check out my website and GitHub!

Work

  • Co-maintaining gspread, an open-source Python API for Google Sheets with over 8 million downloads per month, demanding a high level of future-planning and project management.

  • Management and upkeep of WordPress and Shopify eCommerce sites for an international brand.

  • Maintaining an extensive database of tens of thousands of vehicle paint colours using CSVs and SQL, including keeping it up to date, adapting the database format to the needs of the users, and ensuring a reproducible data pipeline.

  • Development and upkeep of a bespoke PHP plugin enabling dynamic product content for WordPress, as well as programmatic integrations with common WordPress plugins like WooCommerce and Yoast SEO.

  • Developed a mod for the video game Factorio in Lua, involving a low-level partner-plugin for the voice chat client Mumble, written in C. Released on Windows and Linux.

  • Interfaced with an electronic dot-matrix display discarded from a bus station, using C, requiring an involved knowledge of electronics and low-level communication protocols.

Software Engineer

  • Utilised Vue and TypeScript to create an intuitive, user-friendly web application, using robust design patterns and best practices to ensure optimal functionality and user experience.

  • Designed and developed a responsive, feature-rich web application using Flutter and Dart, incorporating a range of views and user-friendly interfaces for maximum ease of use.

  • Employed WPF and C# to create a high-performance application, using SQL and an MVC architecture to facilitate the viewing, manipulation, and analysis of data.

  • Streamlined the deployment process of complex code with multiple dependencies, using Docker and GitLab CI to optimise the development process and improve productivity.

Solar Physics Research Student

Researching novel telescope imaging techniques using quantum gases

  • Developed robust code with Python for fabricating and analysing images from a solar telescope.

  • Performed deep literature review to justify techniques used in the creation of said telescope.

  • Discussed and acted upon desires and needs of telescope engineers, theorists, and observationalists.

Design Engineer Intern

Programmed and debugged a real-time optimisation algorithm on a microcontroller with C. This was used to minimise power losses for a microwave generator, to be used in an ion thruster for space satellites, improving both industry knowledge and personal skills.
