Mostly refined various aspects of major surface areas across web and mobile, such as channels, threads, activity, notifications, and more. Contributed to the major 2020 desktop redesign. ### Product Designer & Software Engineer @ Notion Jan 2018 – Jan 2018 | San Francisco, California, United States Designer #2. As part of a very small and fast-paced team, I spent a half-year tactically executing on key product priorities and accelerating growth. Below is an overview of what I accomplished in just about 6 months. Ask me why I left. Database lookups and rollups Designed an intuitive method for creating point-and-click relations between databases, a.k.a. “lookups” or foreign keys. In a follow-on phase, we added the ability to “rollup” a related cell with simple aggregations, such as count, max, average, etc. This simple building block opened up a whole new world of use cases for database pages, including: - Project management, e.g. connect projects and tasks together, run sprints and capture issues - CRM, e.g. manage your sales pipeline and customize your cycles: opportunities, leads, sales, customers… - Hiring process, e.g. link up candidates to interviews, fold in role-based exercises and interviewer reviews Credit system Designed a generous credit system for individuals and teams. By performing simple and basic actions in the system, users acquire real-currency credit that can be used to get free months of Pro. Basic actions include signing in from different platforms, downloading the mobile app, importing from various services, etc. Content, voice and tone were a major part of the project: this was about helping people easily get started with the product rather than advertising. It ended up doubling as a decent growth vector for new team activations. Dark mode Designed and implemented a full-proof theming system, including custom theme definitions and dynamic grayscale tinting. Shipping this involved refactoring hundreds of files containing locally-declared styles. Interface systems Developed a library of reusable interface components. Codified and implemented a visual system into interactive components and intuitive APIs. Initially built for the core product, later extended to the marketing website. ### Product Designer @ Palantir Technologies Jan 2013 – Jan 2018 | Palo Alto, California, United States Alongside engineers and product managers, I led product design for many initiatives, including the core platform and various data analysis and data management applications sitting on top of it. Products include Gotham, Foundry and Radar. During my first month, a colleague and I developed the primary drag-and-drop interface used to assign Palantir analysts to customers and track deployments across the entire company. Soon after, I started a team dedicated to design systems and developer experience. We built tools to bridge the gap between designers and engineers, and scaled them across the company. We decided to open source the better parts of it in the form of Blueprint, one of the first strongly typed React UI toolkit combining both visuals and interactivity into a coherent API. We improved things further with feedback from the open source community. It has been used by several startups and fast-moving organizations to kickstart their product interface, such as Roam Research, Data USA, Tonic, Aleph… Along the way, I also helped out many business and internal development teams with building out custom software on top of the data platform. ### Software Engineering Intern @ Teleportd Jan 2012 – Jan 2012 | Paris Area, France Designed and engineered the first version of the Teleportd plugin, allowing people to export social photos to any website. Also developed 3 picture layouts for this plugin. Designed a Web application that allows users to search in real-time through millions of social photos shared everyday. Designed the iOS app icon of the very first teleportation device. Developed a Python wrapper around the Teleportd API. ## Education ### Master of Science in Computer Science EFREI - Grande école du numérique Jan 2008 – Jan 2013 ### Computer Science in Business San José State University Jan 2010 – Jan 2010 ### Computer Science in Software Engineering Université du Québec à Chicoutimi Jan 2012 – Jan 2012 ### Bachelor of Science in Mathematics, Computer Science Université Paris-Est Marne-la-Vallée Jan 2008 – Jan 2011 ## Contact & Social - LinkedIn: https://linkedin.com/in/antoinellorca - Portfolio: https://llor.ca/ --- Source: https://flows.cv/antoinellorca JSON Resume: https://flows.cv/antoinellorca/resume.json Last updated: 2026-03-25
