About Evan

Independent fullstack developer, I design and deliver business web applications for companies that want to digitize their processes, expose their data to their clients, or automate their back-office.

My preferred stack: Next.js, TypeScript, Supabase Postgres + Auth) and FastAPI when the project requires Python back-end. On the integration side, I regularly work with Airtable, AI APIs (OpenAI, Anthropic), and document generation services (PDF, Excel).

Some recent projects:
- Secure B2B portal with consumption dashboard, PDF exports, and strict data segregation per client (Row Level Security)
- Automated PLM technical data sheet generation solution for a manufacturer, connected to their Airtable PIM
- Prospecting tool with scraping, multi-criteria scoring, and mapping dashboard for a marketing agency

What I prioritize: clarity on scope and deadlines, a quickly delivered MVP to validate before investing, and maintainable code that you or your team can easily take over. I respond within the day and prefer long-term relationships over one-off missions.

    Following my apprenticeship, I naturally continued the development and maintenance of the application. The objective now is to move towards a "from scratch" solution as Bubble is becoming a constraint.

    September 2022 - April 2023 (8 months)
    The objective of the mission is to create an NFT marketplace. These NFTs are created in collaboration with talents and provide access to an experiential program related to the NFT, its rarity, and its associated "talent".
    To develop this web application, I chose React.js for the front-end and Node.js for the back-end. I also master the Ether.js library, which allows me to easily interact with the blockchain. I am also capable of creating the appropriate Smart Contract for the NFT collection needs.
    Although our application depends partly on the blockchain, some data is stored on AWS. The application itself is also deployed on an AWS instance.

    September 2020 - September 2022 (2 years)
    As part of my apprenticeship, I developed a web application using Bubble.io, Javascript, and Node.js. The application is intended for professionals and allows them to manage their clients and create various resources they need for their work.
    Even though Bubble is a no-code platform, it allows for the creation of custom plugins. I was able to develop various plugins using Javascript and Node.js. For example, one of my first plugins allows for the precise export of data from a page to create an XML or TXT file with a specific template.
