Building a SaaS to Bridge Real-World Data and AI — The Digeiz Web App Story

Building a SaaS to Bridge Real-World Data and AI — The Digeiz Web App Story

Digeiz Web App : Core Application of Digeiz Back-Office

Digeiz develops an AI that leverages computer vision to provide shopping centers with real-time insights on digital screen audiences and visitor flows, measuring demographics (age and gender) and engagement (store visits, dwell time, screen-to-store conversion…).

Their analytics empower clients to refine marketing strategies and enhance customer experiences by optimizing retail space and media effectiveness.

I have worked on the complete Digeiz back-office value chain with a focus on the Digeiz Web App, which relies on 2 branches:

  • Map Editor, the core and most complex application. It is used to create venue maps for deploying Digeiz’s footfall metrics AI.
  • The customer dashboard, used to easy to read and to use data to the customers.

Venue maps are at the core of Digeiz’s value chain and serve multiple purposes:

  • Providing customers with accurate estimates and defining the project perimeter.
  • Coordinating the installation and maintenance of the site’s CCTV camera network.
  • Managing site parameters (e.g., contracts per store, escalator directions, digital screen positions, sizes, and fields of view).
  • Positioning and maintaining all AI visitor counting stations.
  • Creating heatmaps for customer data visualization in the dashboard.

My Role & Responsibilities

  • Conducted UX research across company stakeholders.
  • Led the UI design of the application (visuals withheld for confidentiality reasons)
  • Managed the full web app roadmap and wrote specifications.
  • Oversaw the development team and ensured smooth execution.
  • Trained and managed a junior product manager
  • Built a company and product knowledge database.

Map Editor is not just a visualization tool—it is the foundation of Digeiz AI’s accuracy.
Since AI-driven footfall analytics depend on real-world spatial mapping, the system must process complex site parameters like:

  • Camera positioning & visibility range
  • Store layouts & entry points
  • Multi-floor escalator traffic flow
  • DOOH screen exposure areas

However, site deployment, operation, and maintenance also required periodic updates to account for changes over time, including:

  • Camera status (relocations, deactivations, adjustments)
  • Counting station updates (new installations, recalibrations)
  • Store activity & brand changes (tenant shifts, closures, renovations)

To maintain AI accuracy, these evolving parameters had to be manually updated or periodically checked/refreshed within the system and stored in a structured history.
A key challenge was designing a scalable data model that could integrate these historical updates into AI processing workflows—without requiring real-time tracking—while ensuring consistency and usability over time.

This required translating real-world changes into structured metadata that could be leveraged effectively for both site deployment and AI-driven analytics.


Key Challenges

  • Creating a new product (almost) from scratch.
  • Structuring the Front-End development team and strengthening cross-team collaboration.
  • Translating complex real-world parameters into structured data and metadata usable by AI and the system (spatial & temporal considerations).
  • Designing a solution adapted to all stakeholders, featuring a scalable ACL architecture to manage different user roles and permissions.
  • Delivering fast and continuous updates to the Operations Team, which relied heavily on the tool for site studies and deployments.
  • Continually training teams and documenting the product to keep pace with the rapidly evolving web app and ensure it could be used to its full capabilities.

Impact & Results

  • Developed an application essential and foundational to Digeiz’s operations and growth.
  • Reduced study and deployment time from several weeks to just a few days.
    • Achieved an estimated gain of ~€20k per mall study (-60% time reduction).
  • Structured the company lexicon and knowledge database, solving critical alignment issues between teams.
  • Implemented versioning and document export systems, used by on-site ops and as key annexes for contracts.
  • Delivered a strong « WOW! » effect for customers and prospects.
  • Enabled the study, deployment and management of 38 shopping centers (15 active at the time of my departure).
    • Each shopping center represented an average of €100k ARR.

Key skills for success

  • UX Discovery

    Comprehensive UX discovery of the Digeiz stakeholders and challenges were required in order to create a product that can be used by many but with different focus.

  • Complex Problem Analysis

    Inventing appropriate features, coordinating the roadmap effisciently and collaborating with advanced tech deparement required a holistic understanding of everyone's challenges.

  • Product Design

    Personally designed in Figma the complete UI of the application, including 20+ page and panel templates, and laid the groundwork for its V2 with a new navigation structure and atomic design.

  • Team management

    The Front-End Digeiz dev team needed restructuration. The team was fully restructured, and we implemented orthodox Scrum management, yielding significant improvements.

Company Details

Digeiz offers DOOH audience and footfall analytics for shopping centers, airports, stations & subways, leveraging CCTV & Deep Learning

Testimony
  • « We replaced the camera study process done by our OPS team on google slides by this collaborative web interface. The interface was successfully used to deploy over 15 malls in Europe and was key to make it a success in the constrained timeframe : the duration of our camera studies dropped from several weeks to a few days. Aurele perfectly handled the product development and coordinated the frontend team which was remotely working from Poland. »
