With comprehensive proficiency in the Google Cloud Platform (GCP), I can aptly tackle your Terraform script development project. I have hands-on experience creating resources like networking, GKE clusters with nodes, permament volumes and claims for GKE, Postgres SQL services, and API Gateways in a scalable and secure manner on GCP. Specifically, your task to run a lambda function based on API URLs, and forwarding other requests to a service running in GKE is well within my capabilities.
Not only do I excel in Terraform and GCP, I'm also an automation enthusiast, which intersects well with this project’s requirement. My past tasks in automating hundreds of functions and reports through intelligent workflows have resulted in skyrocketing productivity for my clients. I would apply this same dedication to save your time by automating repetitive tasks in your GCP infrastructure.
Additionally, my web development wizardry will be useful if you need any frontend elements for the Tier portion of you API Gateway solution; optimizing HTML/CSS/JavaScript structures so they execute well at scale. Innovativeness and a focus on problem-solving has always been my key strength. With me on board, be prepared to witness exponential growth in functionality without compromising security or efficiency. I look forward to working together!
