About Me

My name is Alexis Guyot. I design and lead complex cloud-native platforms dedicated to research, data science and artificial intelligence environments, placing automation and user experience at the heart of every architecture.

A systems engineer by training, I work at the intersection of technical architecture, infrastructure industrialization and operational IT strategy. My approach is guided by a simple conviction: build robust, readable and automated systems so their users can focus on what matters, without being held back by underlying complexity.

At Groupe GENES, I led the technical evolution of the Onyxia platform — a multi-tenant Kubernetes infrastructure in production serving scientific entities (ENSAE, ENSAI, CREST, CEPE). This platform pools shared resources (GPU, object storage, open-source services) and allows users to provision self-service environments within a secure, automated and observable framework.

Automation is at the core of how I work. I design platforms built to last, evolve and remain manageable over time. Building infrastructure that makes complexity as readable as a YAML file sums up my approach to systems pretty well.

Beyond the technical layer, I place great importance on cross-team collaboration, process clarification and user adoption — because infrastructure only has value when it is understood and mastered. I am currently pursuing the PMP certification to structure and deepen my project leadership skills according to international standards.

Cloud Resume
Serverless portfolio on AWS — alexisguyot.click
HTML/CSS/JSAWS S3CloudFrontRoute 53LambdaDynamoDBCodePipelineOAC

Built after the AWS Cloud Practitioner cert. Hosted on S3, served globally via CloudFront with OAC enforcing CDN routing. Lambda triggers on each page load to increment a DynamoDB visitor counter. CORS restricts the Lambda URL to the production domain.

Full CI/CD via CodePipeline + GitHub. Domain via Route 53, SSL/TLS via Certificate Manager.
