  • E-flex 5 | 2019-2022

    An application to design connectors for offshore flexible pipes for hydrocarbons up to 16" diameter. It allows engineers to import the pipe setup, perform structural analysis, and size the connector's components by following a set of established methodologies. It further gives input to a 3D CAD for detailed design.

    Having experience as a designer for the product, I was invited to maintain a previous C# desktop application with a similar scope. Seeing many shortcomings, I proposed redeveloping it as a modular web application with a Python and MongoDB back end. The components would be written in a simple way, accessible to non-software engineers, and suitable to replace traditional mechanical design documentation.

    • Eliminated duality between documentation and code and the associated development delay.
    • Allowed most users to understand the code and opened to more contributors.
    • Exposed an API for scripting.
    • Allowed use of units of measurement and tolerances.
    • A new DB allowed searching on hundreds of design parameters.
    • Provided a more appealing and functional interface.
    • Provided more comprehensive testing.
    • Eliminated desktop deployment overhead.
    • Modularity opens to become a generic design product.

  • Barracuda | 2021-2022

    An application to visualize a production map for offshore flexible pipes where one must ensure that original defects in the supplier materials and welds introduced during production are adequately spaced so that the structural capacity of the pipe is not affected. Used for production planning and quality control.

    Initially tasked to adapt the visualization features of an existing, more ambitious but never adopted application for optimizing production. Technical interfacing showed that the goals and architecture of the old software were not in line with the factory's needs, so the idea was discarded, and I proposed a new, lighter implementation that could quickly become useful. It consists of an input spreadsheet capable of synchronizing bi-directionally with a stateless web application, which displays the data and allows to reorganize the input visually.

    Close collaboration with future users resulted in substantial improvement in planning and checking workflows at both the design office and factory. Focus on simplicity allowed us to deliver a working prototype usable on an actual project in a few months, providing invaluable development feedback. The success of Barracuda opened more smart factory activities.

  • Timeline | 2021-2022

    A web application to visualize documentation, training, and software deliverables on a timeline, used by management for resource planning.

    While working on flexible pipe production software, a personal side project was developed as a single-page app focused on simplicity. It presents a shared, color-coded timeline of deliverables and a tree of selectors based on the company organization structure and performs access management based on department membership.

  • Inconnu | 2022

    A lightweight, modular authentication microservice intended to provide easier and consistent user identification for other applications, handling the interface with identity providers (currently supported by Microsoft and Okta).

    A personal initiative to avoid the identity provider set up and simplifying auth coding on different applications.

  • EFMB | 2018-2022

    A spreadsheet application used to prepare mounting instruction books for offshore pipe connectors, printing the workshop forms for producing a particular design configuration.

    The application presents an ordered table of ca. 200 Word documents selected automatically based on a matrix of design options, downloaded from a web server, compiled with project information, indexed, and printed in execution order. Derived from a previous spreadsheet where the logic was completely embedded in the VBA code, this new development has the advantage of being readable and editable by non-programmers and doubles as an overview of the production process, which was not available previously.

  • Graphic Counter | 2022

    A personal project for recording events and displaying their occurrence graphic over a time period (e.g., number of trainings per month and intake of medicines per week). Proof of concept for using Flutter, Firebase, and Play Store.

  • Graphic Counter | 2020–2021

    A personal project for recording events and displaying their occurrence graphic over a time period (e.g., number of hours of training per month and intake of medicines per week). It is a proof of concept for using Vue, Chart.js, and GUN.

  • Micrometer Output Customizer

    A helper application to format the data transferred from a Bluetooth micrometer to a laboratory computer for input in a custom database. I first investigated the feasibility of intercepting Bluetooth communication and implemented it as a keyboard event handler.
