My 100-Day Roadmap to Becoming an AWS-Specialized AI Engineer
From Cloud Fundamentals to Building Production-Ready AI Applications
Artificial Intelligence is evolving rapidly, but building AI applications is only part of the challenge. Deploying, scaling, securing, and monitoring these systems in production requires solid cloud engineering skills.
That's why I've decided to follow a structured 100-day AWS learning roadmap, combining certification preparation, hands-on projects, and real-world engineering practices.
My long-term goal is to become an AI Engineer specialized in AWS, capable of designing and deploying reliable, scalable, and cost-efficient AI systems.
I'm not approaching this journey as a certification collector. I want every concept I learn to translate into practical engineering skills.
My Learning Strategy
I'll dedicate approximately 100 hours over 100 days, studying for two hours every other day.
My approach will follow three principles:
- Learn the fundamentals: Understand cloud infrastructure, security, networking, and AWS architecture.
- Build real projects: Apply concepts using Python, AWS services, and serverless architectures.
- Think like an engineer: Prioritize testing, reliability, observability, security, and cost optimization.
I'll divide my learning time into approximately 38% theory, 42% hands-on practice, and 20% revision and exam preparation.
Phase 1: AWS Fundamentals (Days 1–16)
I'll start by preparing my AWS environment and studying the foundations of cloud computing.
My focus will include cloud service models (IaaS, PaaS, SaaS), AWS Regions and Availability Zones, scalability, elasticity, high availability, and the AWS Well-Architected Framework.
I'll also explore the differences between EC2, Lambda, ECS, and other compute services.
Hands-on project: Cloud Architecture Decision Lab
I'll design two alternative architectures for a document-processing application, comparing EC2-based and serverless approaches.
My goal is to understand architectural trade-offs rather than simply memorize AWS service names.
Phase 2: Security, IAM, and Storage (Days 17–30)
Security is a fundamental responsibility in cloud engineering.
I'll study the AWS Shared Responsibility Model, IAM policies and roles, least-privilege access, encryption, Amazon S3, AWS KMS, and secrets management.
Hands-on project: Secure Document Storage
Using Python and Boto3, I'll build a secure document storage application that interacts with Amazon S3.
I'll focus on private access, proper permissions, error handling, and automated tests.
Phase 3: Serverless Architecture and Databases (Days 31–50)
Next, I'll explore the services that power event-driven applications.
My main topics will be AWS Lambda, API Gateway, DynamoDB, SQS, SNS, EventBridge, and Step Functions.
Hands-on project: Event-Driven Document Processing
I'll develop a serverless pipeline where uploading a document to S3 triggers a Lambda function that extracts metadata and stores processing information in DynamoDB.
This will help me understand asynchronous workloads, event-driven architecture, and how cloud services communicate.
Phase 4: Networking, Monitoring, and Cost Optimization (Days 51–66)
A working application isn't necessarily a production-ready application.
I'll study VPC networking, subnets, security groups, API Gateway, Amazon CloudWatch, AWS CloudTrail, and cost management.
Hands-on project: Document Processing API
I'll extend my previous project with an API for retrieving processing results, structured logging, basic monitoring, and error handling.
I'll also document architectural decisions, potential failure scenarios, and operational costs.
Phase 5: AI Engineering with AWS (Days 67–80)
This is where my cloud foundations begin connecting directly with my AI Engineering goals.
I'll study Amazon Bedrock, Amazon SageMaker AI, foundation models, embeddings, inference, and the fundamentals of Retrieval-Augmented Generation (RAG).
I'll also explore model evaluation, inference latency, token usage, and cost optimization.
Hands-on project: AI Document Classifier
I'll extend my document-processing pipeline with an AI component powered by Amazon Bedrock.
Using Python, Boto3, and Pydantic, I'll implement structured outputs, validation, automated testing, and basic inference monitoring.
The objective is to understand how AI capabilities integrate into a real cloud-native application.
Phase 6: AWS Cloud Practitioner Certification (Days 81–100)
During the final 20 days, I'll focus on preparing for the AWS Certified Cloud Practitioner (CLF-C02) exam.
I'll review the four official domains:
- Cloud Concepts
- Security and Compliance
- Cloud Technology and Services
- Billing, Pricing, and Support
I'll use official AWS practice exams, review my mistakes, and focus on understanding why each answer is correct.
My personal readiness target will be at least 85% on two different timed practice exams.
My Main Portfolio Project
Instead of developing several disconnected applications, I'll work on one evolving project:
Cloud-Native AI Document Processing System
My planned technology stack includes:
Python | Boto3 | Amazon S3 | AWS Lambda | DynamoDB | API Gateway | Amazon Bedrock | CloudWatch | Pytest
Throughout development, I'll apply an engineering lifecycle built around four stages:
Build → Test → Deploy → Monitor
I want my final GitHub repository to demonstrate more than a functioning application. It should include architecture diagrams, automated tests, deployment instructions, observability, security considerations, and documented engineering trade-offs.
Learning Resources
I'll prioritize authoritative resources rather than jumping between multiple courses.
My primary learning sources will be:
- AWS Skill Builder — Official courses, certification preparation, and labs.
- AWS Documentation — Technical references and implementation guides.
- AWS Builder Center — Workshops, community learning, and technical content.
- AWS Well-Architected Framework — Architectural best practices.
I'll also use the official exam guides to keep my study plan aligned with certification objectives.
What's Next After These 100 Days?
The Cloud Practitioner certification is only my starting point.
After completing this roadmap, my next target will be the AWS Certified AI Practitioner, followed by more advanced certifications depending on my technical development.
I'm particularly interested in the AWS Certified Developer – Associate, AWS Certified Machine Learning Engineer – Associate, and AWS Certified Generative AI Developer – Professional.
As my knowledge develops, I plan to build more advanced applications involving AI agents, LangGraph, RAG pipelines, and production-grade LLM architectures deployed on AWS.
Final Thoughts
My goal isn't to master AWS in 100 days. It's to build a strong foundation for becoming an AWS-specialized AI Engineer.
I believe the combination of cloud architecture, Python development, AI engineering, and real-world projects will be far more valuable than certifications alone.
I'll document my progress, share technical insights, discuss architectural decisions, and publish what I learn along the way.
For me, the most important outcome won't be the certification itself. It will be the ability to design, build, deploy, test, and monitor AI applications with confidence.
