Solutions portfolio
I've built several open sourced solutions. Have a look at what I've created and see if there's anything that would work for you or your organization.

Google Cloud Platform solutions
Cloud Instance mapper
Cloud Instance mapper creates a score-based mapping of different cloud IaaS VM instance types from EC2 and Azure Compute to Google Cloud Platform instance types, based on fresh data fetched from APIs. You can also map AWS RDS instances to Google Cloud SQL database types.
gcpviz
gcpviz is a visualization tool that takes input from Cloud Asset Inventory,
creates relationships between assets and outputs a format compatible with graphviz.
Pubsub2Inbox
Pubsub2Inbox is a swiss-army knife for reacting to Pub/Sub message. It can perform many different tasks, like sending out emails using your own SMTP servers, copying files between buckets, running BigQuery queries, turning single messages into multiple ones (fan out), etc.
Custom Role Manager
Custom Role Manager is a tool that can be used to keep custom roles up to date. You can source permissions from either testable permissions of a resource or from another role or set of roles.
GCS2BQ
Collect all your Google Cloud Storage metadata from your organization and build storage dashboards.
Per-user Metadata Proxy (to be published)
per-user-metadata-proxy is a proxy server that can provide separate Service Account identities for workloads
running under different users on a single Compute Instance server. It uses the /proc filesystem's list of TCP
connections to find the local identity of the workload and maps any gcloud/Cloud SDK/curl requests to another
service account.
gsnapshot
gsnapshot provides a more traditional experience in managing VM instance level snapshots, rollbacks
and commits.
pubsub2syslog
A very simple example of reading from Pub/Sub and writing the messages to syslog (can be used for example to transport audit logs to security products that support reading syslog).
Lambda compatibility for Cloud Run
Running unmodified AWS Lambda functions on Cloud Run? With credentials? It's possible by using a Lambda Runtime API emulator written in Go.
Terraform solutions
Persistent counter provider
A provider for keeping persistent counters for resources.
