Deploying Flutter Web to Firebase Hosting with GitHub Actions CI/CD

Deploy Flutter Web to Firebase Hosting using GitHub Actions CI/CD. Firebase Hosting is a fast path to production due to its ease of use and auto-HTTPS setup. To deploy, configure Firebase Hosting with a GitHub Actions workflow, using the FirebaseExtended action. Set up a service account in the Firebase Console and store the private key as a secret in your GitHub repository. This allows for automatic builds and deployments to Firebase Hosting.

What is RAG? A Beginner's Guide to Retrieval-Augmented Generation (With a Full Pipeline Walkthrough)

RAG (Retrieval-Augmented Generation) is an AI framework that integrates information retrieval into Large Language Models (LLMs) to improve factuality and relevance. It addresses challenges of frozen LLMs, high retraining costs, and regulatory requirements. RAG decouples knowledge from the model, allowing for dynamic retrieval and up-to-date answers. To implement RAG, a knowledge base is prepared by gathering relevant documents, and then the LLM looks up information in the base to answer questions. This approach is particularly useful for regulated industries where answers need to be backed by sources.

Moving a large-scale metrics pipeline from StatsD to OpenTelemetry / Prometheus

A large-scale metrics pipeline was migrated from StatsD to OpenTelemetry and Prometheus, showcasing the scalability of the new system. This move is significant as it highlights the growing adoption of OpenTelemetry and Prometheus in the industry. Engineers can learn from this example and consider migrating their own pipelines to take advantage of the benefits of OpenTelemetry and Prometheus. The migration process involved significant changes to the system architecture and required careful planning and execution. The outcome demonstrates the feasibility of using OpenTelemetry and Prometheus for large-scale metrics collection.

FinOps Isn’t Slowing You Down — It’s Fixing Your Pipeline 

FinOps is helping engineers optimize cloud costs by integrating cost estimates and policy-as-code into DevOps workflows, reducing the need for costly firefighting after deployment. This approach, called 'shift cost left,' allows for more efficient cost management. Engineers can use tools like Terraform and GitHub to implement this strategy. By doing so, they can reduce cloud costs and improve overall pipeline efficiency. This is especially important for large-scale cloud deployments.

Building a Docker + Kubernetes Project from Scratch with Helm

This article guides engineers through building a Docker + Kubernetes project from scratch using Helm. It covers a 2-tier microservices application, automating deployment, scaling, and service management. To implement, follow steps to build the backend, dockerize the application, create a frontend with Nginx, run a Kubernetes cluster, and create a Helm chart structure. This project simulates a real-world DevOps workflow.

Agentic CI/CD is Not Automation: Why the Distinction Will Define DevOps in 2026

Teams are misusing LLM-powered agents in CI/CD pipelines, calling it 'agentic CI/CD.' This is not automation, but rather decision-making. This conflation will impact DevOps in 2026. Engineers should understand the difference to make informed decisions. Focus on actual automation, not just fancy tools.

How I Built a Multi-Agent Code Review Pipeline That Actually Works

A team built a multi-agent code review pipeline to speed up the review process, reducing time from 4 hours to 30 seconds and catching 94% of issues. This was achieved by having specialized agents that share contracts, not memory, and focus on different aspects of code review. The result is a more efficient and effective code review process. To replicate this, focus on better handoffs between agents rather than adding more agents. This approach can be applied to any team looking to improve their code review process.
