About Anthony

For over 8 years, I have been passionate about creating robust and scalable SaaS applications that address complex business problems.

As a freelance developer, my mission is to quickly integrate into your ecosystem to accelerate your product roadmap. I am involved in all phases of your projects, from the design of the MVP to the evolution of an existing platform.

My expertise covers the entire modern stack:
🔹 Frontend: Fluid and intuitive interfaces with React.
🔹 Backend: Robust business logic and performant APIs with Node.js (REST & GraphQL).
🔹 Architecture: Design and implementation within Microservices and event-driven environments.
🔹 Databases: Optimized use of NoSQL (MongoDB) and SQL (PostgreSQL, MariaDB) databases.

Beyond the technical aspects, I am your partner. Through transparent communication, a deep understanding of your business challenges, and an UI/UX eye, I don't just develop features: I build solutions that have a real impact on your users and your growth.

Looking to strengthen your team with an autonomous and proactive expert? Contact me to discuss your technical challenges and how I can help you overcome them.

Experience

  • Universus Technologies
    Associate & Lead Developer
    MEDICAL
    March 2024 - August 2025 (1 year and 5 months)
    Québec City, QC, Canada
    Universus Technologies is a company specializing in high-quality transcription and medical report writing for healthcare professionals, optimized by AI.

    As an associate, I took on a dual role of strategic partner and technical leader. My mission was to define and execute a new technological vision to unlock the company's growth, which was critically hampered by manual processes and unstable infrastructure.

    ✅ Orchestration of complete automation of the production workflow. I designed and developed a new event-driven system (Node.js, Trigger.dev, Supabase) that transformed the company's core. We moved from a limiting manual process (distribution, tracking, billing) to 100% automated production, enabling us to handle much larger volumes while reducing operational costs.

    🤖 Implementation of an advanced AI pipeline for processing medical reports. I integrated and orchestrated several AI services (Gemini, OpenAI, Anthropic) to automate the transcription, correction, and translation of reports, as well as other production workflow processes. I also implemented solutions for advanced audio processing (silence removal, format conversion), radically increasing the quality and speed of deliverable production.

    🚀 Development of the complete application ecosystem (Full Stack). I led the development of all user interfaces: a secure client web portal, an interface for transcribers, and a comprehensive administrator dashboard. I ensured a consistent and intuitive user experience across the entire platform, from creating a case to delivering the final report, and then to client and transcriber billing.

  • Hyperspread
    Senior Full Stack Developer / Technical Lead
    RETAIL (LARGE RETAILERS)
    April 2021 - January 2023 (1 year and 9 months)
    Paris, France
    As a senior developer and technical lead within the product team, I was responsible for developing key features for this SaaS/PaaS platform, optimizing performance, and providing technical mentorship to the team.

    ✅ Design of a scalable data architecture (Custom Fields). Starting from a specific client need, I proposed and developed a generic system to extend the properties of any entity in the solution. This initiative accelerated the deployment of new features and offered greater customization flexibility to clients, without developer intervention.

    🚀 Performance optimization and technical mentorship. Faced with growing performance issues (N+1 problem), I implemented a GraphQL batching solution that drastically reduced the number of database queries. I then trained the entire team on its use to ensure the adoption of best practices and the sustainable performance of the application.

    🛠️ Development of complex business modules at the core of the platform. I led the end-to-end development of several essential functional components for the client experience, such as a customizable payment system (invoices, quotes), integration of SSO with Zendesk, and advanced data management tools like an import/export system.

  • Bob! Desk (GMAO SaaS)
    Full Stack Developer
    CIVIL ENGINEERING
    March 2020 - March 2021 (1 year)
    Paris, France
    As the lead developer working directly with the CEO and CTO, I had complete autonomy to drive the evolution of the Bob! Desk CMMS, a SaaS solution used notably by the Marie Blachère group. In addition to ongoing maintenance and continuous roadmap development, I led several foundational projects that transformed the product:

    ✅ Modernization and reliability of the codebase. I took charge of the complete refactoring of the back-office, transforming a legacy codebase (slow, unstable, and difficult to maintain) into a solid technical foundation. This initiative drastically reduced bugs, improved performance, and increased the team's velocity for future development.

    ⚙️ Automation of critical business processes. I designed and developed a complete invoicing module for all platform stakeholders (clients, contractors), automating a key process and reducing the workload of the client's administrative team. I also implemented an automatic intervention ticket assignment system and synchronization with external calendars (Google/Microsoft) to streamline operations.

    📈 Development of strategic features. To meet the needs of a major client, I implemented high-value-added features: a customizable fields system to adapt the solution to specific client needs, a statistical dashboard for activity management, and a migration tool to accelerate the onboarding of new clients.
