Production-grade task manager on AWS built to demonstrate cost-aware infrastructure from day one. Auto Scaling Group with scale-out at 70% CPU and scale-in at 30%. Two-layer self-healing: Docker restarts crashed containers in seconds, ASG replaces failed instances in minutes. RDS password lives only in Secrets Manager, fetched at boot via IAM role scoped to that single secret ARN. Full network isolation, Jenkins CI/CD, CloudWatch alarms wired to scaling policies.

4-server Linux environment built from a single golden image template. All configuration managed through Ansible playbooks and roles — nothing configured manually twice. System hardening across all servers: SSH key-only auth, UFW firewall rules, Fail2ban. 3-tier application stack where each tier only accepts connections from the previous tier. Node exporter on all servers for centralized metrics collection.

Full-stack web app that takes a LinkedIn PDF and job description and outputs a tailored, ATS-clean Word document in under 15 seconds. 4-step AI pipeline via Groq: extract, rewrite, keyword match, tailor. Stateless by design, no database, no stored data. Rate limiting per IP, bot guard, CORS restricted to production origins. GitHub Actions CI/CD deploys backend to Render and frontend to Vercel on every merge. Live at readytoapply.work.
