Medtronic is a global medical technology company, recognized as a leader in medical devices and health solutions.

As a Solutions Architect within the UNiD service team, I contributed to the development and deployment of an advanced cloud-native solution for designing and manufacturing spinal implants:

• Audit and redesign of AWS infrastructures and critical applications, focusing on high availability, performance, security, scalability, and cost optimization using EC2/ECS, VPC, RDS, S3, Global Accelerator, Cognito, among others.

• Modernization of the Data Lake to a serverless architecture combining Lambda, Step Functions, Glue, SNS, SQS, to improve resilience and reduce complexity.

• Automation of multi-environment deployments using Bitbucket Pipelines, Azure DevOps, CodeDeploy, Terraform, CloudFormation, ensuring consistency in application and database deliveries (including anonymized copies).

• Implementation of CI/CD pipelines integrating unit, integration, and performance tests, as well as documentation generation.

• Deployment of a comprehensive DevSecOps approach with SCA, SAST, IAST, RASP, CSPM tools, secret management via Secrets Manager, threat modeling with Data Flow Diagrams, and Security Risk Assessments.

• Strengthening of the security posture: access management (IAM), encryption (KMS), audit and traceability (CloudTrail, Config), threat detection (Inspector, GuardDuty), securing external access (WAF, VPN), in compliance with ISO 27001, HIPAA, GDPR standards...

• Contributions to the quality system: documentation of specifications, procedures, and quality control.

• Administration and supervision of Linux & Windows environments hosting .NET and Python applications, with Shell, PowerShell, Python, and SQL scripting.

Newtone Technology (now QIMA Newtone) specializes in the development of acquisition systems and software solutions for appearance measurement. The company designs high-precision technologies to analyze and quantify complex visual parameters, such as color, texture, and gloss, for various applications, particularly in the medical, pharmaceutical, and cosmetic sectors, thereby facilitating the improvement of their quality control and research processes.

As an architect and developer, I designed and developed the CIPaaS service from scratch, an innovative solution for connecting acquisition systems and image processing solutions via a secure web application, ensuring real-time monitoring and control of clinical studies:

• Design and full development of CiPaaS, a web & cloud platform (Symfony / Angular) deployed on AWS (VPC, EC2, RDS, S3, WAF, VPN, IAM, KMS, Global Accelerator).

• Implementation of real-time distributed computing for clinical image preprocessing via AWS Step Functions and Lambda.

• Adaptation of the platform for major clients in the cosme-dermatology sector, including the portability of CiPaaS to dedicated AWS infrastructures and the development of custom services meeting specific requirements for confidentiality, compliance, and business workflows.

• Close collaboration with internal hardware, image, and software teams to ensure interconnection between acquisition systems, image processing, and the platform.

• Secure and scalable architecture, with network management, IAM, encryption (KMS), deployment automation, and application supervision.

• Contribution to product specifications, clinical workflow modeling, and data model definition.

Seety was a mobile application focused on creating an enriched and immersive jogging experience, allowing users to discover and share new running routes with geo-located audio podcasts.

As a co-founder and technical lead, I was responsible for the entire platform design and development, from architecture to production:

• Design and development from scratch of the web platform (PHP / MySQL) and the native Android application (Java), featuring real-time geolocation, route synchronization, audio streaming, statistics, and user management.

• Supervision of the iOS application development, liaising with an external provider and then an internal resource, and coordinating with the design and product teams to ensure functional and UX consistency.

• Deployment of the web application on OVH Cloud, implementing security, caching, and monitoring mechanisms: Nginx, Varnish, Let's Encrypt, Monit, Fail2Ban.

• Publication of the mobile applications on official Android and iOS stores, managing updates, testing environments, and user feedback.

• Management of infrastructure, monitoring, and performance optimization, ensuring service reliability despite limited resources.
