Moving the app off its default *.run.app URL onto a company subdomain with Cloud Run domain mappings: the domain-verification step the runbooks skip, why a zone apex takes A/AAAA records instead of a CNAME, why the cutover order matters when an OIDC audience is involved, and a 502 that looked like a broken deploy but was a TLS cert still propagating.
Adding deadline reminders to a workflow tool: a Cloud Scheduler → Cloud Tasks → worker pipeline, why IAM run.invoker was the wrong lock for a public SSO-gated Cloud Run app, verifying OIDC tokens in-app instead, making retries idempotent, computing Japanese business days without hardcoding holidays, and a Next.js standalone build trap with Google client libraries.
When Slack SSO works for staff but not guest accounts: adding Google sign-in as a gated fallback, re-keying users on email, preserving Slack mentions for users who never sign in with Slack, and enforcing who may use which door.
The cloud half of the DB: enabling GCP APIs, choosing the cheapest Cloud SQL tier and why, Private Service Connect with no public IP, serverless VPC egress, and migrating a database you cannot reach from your laptop.
Replacing an in-memory mock with local Postgres: Docker, a Drizzle schema and first migration, seeding, swapping the data layer, and designing for private-network cloud access.
A new design draft and a fresh requirements list arrived mid-build. How I triaged them against priority, deferred the integration-heavy features without stalling, kept the plan doc as the source of truth, and decided the schema was finally stable enough to stand up the database.
A fullstack workflow tool for designers receiving creative work requests, built with Next.js 16, Drizzle on Cloud SQL Postgres, and Slack SSO. Deployed to Cloud Run with GitHub Actions CI/CD. Covers stack planning, AI-assisted development setup, and GCP infrastructure.
A Slack bot powered by Vertex AI Gemini with GCS-based knowledge base, deployed to Cloud Run with GitHub Actions CI/CD. Covers Python dev setup with uv, Flask REST APIs, Gemini integration, and cloud infrastructure.
Four internal operations automations driven by Slack Workflow Builder forms, wired to Google Sheets, Google Calendar, GitHub, and an AI coding agent. A Flask + slack-bolt bot on Cloud Run reads each form submission and turns it into the right action: a private DM, a spreadsheet row plus calendar event, an owner mention, or an auto-generated pull request.
