This is a submission for the 2025 New Year Writing challenge: Retro’ing and Debugging 2024.

Memorable Achievements
Professional Certifications
Achieving the AWS Certified Machine Learning – Associate certification was a defining moment in 2024. It deepened my understanding of AWS’s machine learning ecosystem, including services like Amazon SageMaker, Rekognition, and Comprehend. This credential reinforced my ability to build, train, and deploy machine learning models at scale, enabling me to tackle real-world AI challenges.

Mastering AWS AI Services
Beyond certification, I explored AWS’s AI and machine learning tools in greater depth. Leveraging Amazon SageMaker, I developed end-to-end machine learning workflows, and utilized Rekognition for image recognition tasks and Comprehend for natural language processing. These experiences broadened my expertise in applying cloud-based AI solutions to diverse use cases.

Innovative Product Development
Using insights from AWS's machine learning tools, I expanded my product line with innovative designs, such as themed keycaps and collectible stickers. These efforts combined creative thinking with data-driven decision-making, allowing me to better align my offerings with market trends.

Building Scalable AI Workflows
With the power of AWS, I successfully optimized workflows for scalability and efficiency. By integrating AWS Lambda and Step Functions, I automated key processes, reducing manual overhead and ensuring seamless operation across projects.

Resilience in Marketplace Ventures
From handling competitive dynamics to refining my product strategies, I combined my technical knowledge with business acumen. This balance allowed me to innovate and sustain resilience in a competitive environment, particularly by using data insights from AWS tools to guide decisions.
