The cruise line seeks to design and deliver marketing campaigns that resonate with specific audiences, optimizing bookings, and enhancing guest satisfaction.

Demographics Data Collection:

Collect data such as age, gender, family status (e.g., single, married, kids), income level, occupation, nationality, and education. This data can be sourced from past bookings, guest surveys, and third-party data providers.


Building the Chatbot:

RAG Model Integration: Use RAG to combine the benefits of retrieval-based and generative approaches. The model will retrieve relevant FAQ passages and use them as context for the LLM.

LLM Integration: Use GPT-4 or a similar model to generate detailed responses based on the context provided by the RAG model.

Full Picture

While my official designation is "Enterprise Architect - Data Architecture," it barely scratches the surface of the myriad roles I've undertaken. My daily tasks seamlessly blend responsibilities of an Enterprise Architect, a Data Architect, and a Solution Architect.

Direct Technical Engagement:

I'm a firm believer in the hands-on approach. Writing code and working elbow-to-elbow with engineering teams isn't an exception for me; it's the norm. This close-knit collaboration ensures the architectural guidance I provide is always grounded in practical realities.

Bridging Strategy and Execution:

My interactions aren't confined to tech teams. I'm regularly in strategic discussions with our C-suite - from the CIO and CDO to the Chief Architect and CMO. These dialogues help me align our data architecture endeavors directly with overarching enterprise goals.

Efficiency through Simplification:

One of my core philosophies is "Simplicity as an Enabler." By refining and simplifying our architectural frameworks, I've ensured they empower us, rather than hinder progress.

Staying Ahead of the Curve:

I'm always on the lookout for emerging tech that can elevate our operations. For instance, I've dived deep into Large Language Models (LLM), leading studies and crafting prototypes, all while gauging the potential of AI integrations across the enterprise spectrum.

Demystifying Complexity:

Complex concepts? I have a knack for breaking them down. Whether it's discussing intricate domains with teams or presenting to stakeholders, I pride myself on clarity and coherence.

A Commitment to Growth:

Mentorship, to me, is more than a program; it's a passion. I've taken many mentees under my wing, guiding them through their professional journeys, sharing insights, and fostering their growth.

In essence, while my title is a testament to my primary focus, my roles and responsibilities are as diverse as they are impactful. At the end of the day, it's all about adding value to our organization, every step of the way.
