From local code to a fully automated CI/CD pipeline. 🚀 I just wrapped up a major update to my portfolio! It’s no longer just a React site—it's a production-ready environment. I’ve integrated: ✅ Dockerized Architecture: Using multi-stage builds and Nginx for high-performance local serving. ✅ Automated Workflows: GitHub Actions now handle my deployments to Vercel with zero manual effort. ✅ Cloud Media: Integrated Vercel Blob to serve project walk-through videos seamlessly. #DevOps #ReactJS #Docker #GitHubActions #JuniorDeveloper #WebDevelopment

Task Orchestrator: Resilience & Scale A cloud-native task management engine built for modern distributed teams. This project bridges the gap between fast backend execution and automated DevOps infrastructure.😊

Habit Grind is a high-performance, offline-first mobile application designed to bridge the gap between local speed and cloud reliability. Offline-First Core: Built with React Native and SQLite to ensure zero-latency user interaction, regardless of network status. Serverless Sync Architecture: Developed a custom sync engine using Hono.js and AWS Lambda to handle secure data backups without the overhead of a traditional server. DevOps-Driven Reliability: Every update is pushed through a GitHub Actions CI/CD pipeline, achieving a production-ready deploy in just 66 seconds. Linux-Optimized Environment: Developed exclusively on Pop!_OS to leverage low-level kernel control for smoother Android/iOS emulation and faster build times.😊

Live-Ops Command Center: Resilience-First Monitoring Platform I engineered a production-grade monitoring dashboard focused on system resilience and live telemetry. This project demonstrates a 'Zero-Babysitting' infrastructure mindset, ensuring maximum uptime through container self-healing. The Goal: To move away from 'fake metrics' and build a tool that provides real-world system awareness for distributed architectures. 📂 Source Code: [https://github.com/Codemonkey-API/live-ops-system ]
