I’m excited to share a set of mobile apps I’ve recently completed and published on both the Google Play Store and the Apple App Store. These apps are designed with a simple goal in mind: to make meaningful, structured content more accessible, whether you’re studying theology or improving your English vocabulary. 📱 Now Available on Both Platforms All apps are live and available for download: Google Play Developer Page: https://play.google.com/store/apps/dev?id=5835943159853189043 Apple App Store Developer Page: https://apps.apple.com/ca/developer/q-z-l-corp/id1888794100 📖 Theology & Confession Study Apps For those interested in Reformed theology and classical Christian teachings, I’ve developed a series of apps that present foundational texts in a clean, focused reading format: The Belgic Confession Canons of Dort Heidelberg Catechism Westminster Shorter Catechism Each app is designed to provide a distraction-free experience, making it easier to read, reflect, and revisit these im...

Today is January 1st, 2026 . Before rushing into new goals, I spent some time looking back at the past 12 months of data for this blog — the quiet numbers that tell a very honest story. Looking Back at the Numbers Over the past year: 📈 Total views: ~44,600 👀 Daily average visits: ~200 💬 Comments: 19 💰 AdSense income: about $0.01 per month At first glance, these numbers may look small — especially the income. But when I zoom out, I see something more meaningful. This blog has been quietly read every single day . No viral posts. No aggressive promotion. No paid traffic.

At this point, your Next.js standalone app: Builds cleanly Runs in a minimal Docker image Deploys correctly on Kubernetes / OpenShift Serves static assets properly Uses runtime configuration and secrets Now let’s make it resilient and scalable . Why Health Checks Matter Kubernetes relies on health checks to: Know when a pod is ready to receive traffic Restart unhealthy containers Safely roll out new versions Without proper probes, traffic can be sent to a pod that isn’t ready yet. Readiness Probe A readiness probe tells Kubernetes: “This pod can accept traffic.” For most Next.js apps, the root path works well: readinessProbe: httpGet: path: / port: 3000 initialDelaySeconds: 10 periodSeconds: 5 If your app depends on downstream services (APIs, d...
