Profile

I am Greg. (alias Grégoire), a Solution Architect at AWS WWPS, focused on helping organizations understand, adopt, and extract business value from Cloud, AI, and Automation technologies.

With over 20 years of experience spanning public sector, financial services, healthcare, manufacturing, and telecom, I bridge the gap between business strategy and technical execution. My approach is grounded in a simple principle: technology should serve business outcomes, not the other way around.

I specialize in:

  • Cloud Architecture — designing scalable, secure, and cost-efficient solutions on AWS
  • AI/LLM & GenAI Integration — embedding generative AI into real-world business processes (RAG, MCP, Bedrock Agents)
  • Agentic Workflows — designing and implementing autonomous agent pipelines (GitHub Agentic Workflows, AWS Bedrock Agents) to automate complex, previously manual back-office and operational processes
  • Business Automation — modeling and automating complex business rules and processes at scale (BPM, DMN, Rule Engines)
  • Modern Application Design — microservices, event-driven architectures, API-first design, Kubernetes

Having delivered projects for organizations ranging from small nonprofits to institutions managing processes for 70 million people, I am equally comfortable advising a CTO on transformation strategy and rolling up my sleeves to architect and implement the solution.

Prior to AWS, I served as a Senior Cloud Architect at Red Hat for over a decade, and as a Tech Leader at Capgemini for several years.

What I Can Do For Your Organization

Whether you are a startup, a mid-size company, or a large enterprise, the challenges are often the same: too many manual processes, siloed systems, slow delivery cycles, and difficulty extracting value from data and AI.

I can help you:

  • Define and execute a Cloud or AI adoption strategy aligned with your business goals
  • Identify and automate high-value, time-consuming workflows using agentic and AI-driven approaches
  • Design scalable architectures that grow with your organization
  • Integrate GenAI and LLM capabilities into your existing products and processes
  • Modernize legacy systems with pragmatic, low-risk migration paths
  • Build and mentor engineering teams on Cloud-native and AI-first practices

Engagements I have successfully delivered include:

  • Executive and stakeholder meetings — business, sales, project, and delivery topics
  • Transformation, integration, and development projects
  • GenAI/LLM integration into IT systems, chatbot and agentic workflow design
  • Cloud architecture, application design, ADR, and Cloud patterns
  • Customer feedback loops on product adoption, success metrics, and pain points
  • Team planning and technical leadership
  • Hands-on coding and continuous integration
  • Knowledge transfer, training, and technical evangelism
