Experience
Decentralized Creator Investment Platform
I served as the DevOps architect for a decentralized blockchain platform designed to bring cryptocurrency technology into the media and entertainment industry. The platform enabled fans to invest in and support their favorite creators through a social network-like experience, blending blockchain tokenomics with creator engagement.
My role focused on architecting the full cloud delivery pipeline and ensuring the platform could scale reliably as user adoption grew. I designed and implemented end-to-end CI/CD pipelines, analyzed the application architecture, and selected appropriate AWS services to maximize reliability, scalability, and operational efficiency.
To run the multi-repository microservices environment, I chose Amazon ECS and AWS Fargate, enabling fully managed, serverless container orchestration with predictable deployments and reduced operational overhead. My contributions ensured a robust, secure, and highly scalable cloud foundation for the platform.
