CoderRange - Endless Programming Languages

Are you a Data Analyst with 2-8 years of experience craving the next-level skills to crack complex datasets, optimize pipelines, and deliver real-time business impact?
If yes, this meetup is your golden ticket!
***
🎯 What we’re covering:
🚀 Extreme Real-Time Analytics & Data Internals

• Architecting lightning-fast data pipelines that don’t break under pressure
• Understanding streaming data platforms (Kafka, Spark Streaming) — beyond the basics
• Real-time anomaly detection, predictive analytics, and instant dashboards

📊 Advanced Data Modeling & Query Optimization

• Deep dive into SQL internals and performance tuning for massive datasets
• How to design scalable, maintainable data models for complex business scenarios
• Data warehouse vs. data lake vs. lakehouse: pros, cons, and use cases

🛠️ Tools & Techniques You’ll Love

• Leveraging Python & R for advanced stats and machine learning
• Automation hacks for ETL, data cleaning, and data quality checks
• Hands-on tips for using BI tools like Power BI, Tableau with real-time data

📈 What real employers expect from senior analysts

• Storytelling with data under extreme time constraints
• Cross-functional collaboration: influencing product and engineering with data
• From data wrangling to strategic decision-making: your complete playbook

Why it works: Most pros know K8s basics—this dives into real-world challenges and solutions.
Subtopics:

• Real production outage war stories
• Node pressure, evictions, autoscaling pains
• Resource tuning (CPU/Mem/Pod limits)
• Monitoring beyond Prometheus & Grafana
• Readiness/Liveness vs startup probes
• Helm pitfalls and GitOps wins

💡 Add Live Demo: Chaos engineering with `kubectl` and `chaos-mesh`.

### ⚙️ 2. “Kubernetes at Scale: 1 Million Pods and 10,000 Nodes”

Why it works: Shows high-scale architecture and tuning—perfect for infra-heavy audiences.
Subtopics:

• etcd scaling and shard patterns
• kubelet optimizations, CRI tuning
• Cluster federation vs multi-cluster service mesh
• Use of CRDs to customize control plane
• Scaling logs/metrics/ingress

💡 Add Open-source Showcase: Show your infra-as-code Terraform/GitOps setup.

***

### 🔐 3. “Zero Trust Security in Kubernetes”

Why it works: Security is top priority; show real isolation models and best practices.
Subtopics:

• NetworkPolicies and Calico setup
• RBAC hardening (least privilege)
• Secrets management: HashiCorp Vault + K8s
• Zero trust service mesh (Istio/ZTunnel/Linkerd)
• Container image scanning (Trivy/Snyk)

💡 Live Attack Demo: Try a misconfigured pod → access cloud metadata, then fix.

***

### 🚀 4. “From Dev to Prod: Enterprise CI/CD with Kubernetes”

Why it works: DevOps folks love end-to-end automation.
Subtopics:

• Jenkins + ArgoCD + Helm flow
• Canary & Blue/Green deployments with Istio
• GitHub Actions + K8s deployment pipeline
• Secrets management in CI
• ChatOps and Slack deploy bots

💡 Live Deploy: Trigger code → GitHub Actions → ArgoCD deploy → verify in real-time.

### 🤖 5. “Kubernetes Operators: Automate Anything”

Why it works: Few people master Operators; it’s a hot area.
Subtopics:

• What’s an Operator vs Controller
• How to write one (Kubebuilder)
• Use case: Auto-scaling DB clusters, Backup jobs
• Watchers, Reconcilers, CRDs explained
• Real operator (e.g. Prometheus, Kafka)

💡 Live Demo: Build and deploy a mini custom Operator.
