New Framer template launched

Built this template from scratch, learned a lot, fixed way too many tiny issues, and it's finally out.

If you're building a modern website in Framer, hope this saves you some time.

Would love to hear what you think. 🚀

A framer template for indie hackers, solo founders, and SaaS builders who want to launch fast without the unnecessary complexity. Clean, conversion-focused, and ready to customize.

This is my second template released in August, and I'm just getting started.

Feedback is always welcome!

Shipped: a full DevSecOps pipeline running on EKS Via Karpenter 🥷 Spent the last stretch building out infrastructure for my e-commerce project (BUSHIDO) — and last night it all finally clicked into place end to end. Commit → scan → build → scan image → push → deploy → observe. Fully automated, zero manual kubectl. 🔹 Multi-AZ EKS cluster with Karpenter for autoscaling 🔹 8-stage Jenkins pipeline — SAST (SonarQube), SCA (OWASP Dependency-Check), Trivy image scanning, all gating the build before it ships 🔹 ECR with immutable tags + AES-256 encryption 🔹 ArgoCD GitOps — Jenkins updates the tag, ArgoCD syncs it automatically 🔹 Full observability with Prometheus + Grafana — nodes, pods, network, all in one dashboard Want to deploy it yourself? Code is fully open source, links below 👇 Would love feedback from anyone who's built similar pipelines, or roasts on what I could do better. 🔗 App repo: https://github.com/HamzaMaLik121/samurai-themed-e-commerce-store.git 🔗 Infrastructure repo: https://github.com/HamzaMaLik121/Samurai-Infrastructure-.git #DevOps #Kubernetes #EKS #Jenkins #ArgoCD #GitOps #AWS #DevSecOps #OpenSource #Karpenter
