# Designing and automating multi-environment AWS infrastructure, CI/CD pipelines, and production observability.
$ Key Responsibilities:
- ▸ Restructured and fully imported a multi-environment (dev/staging/prod) AWS infrastructure into Terraform; built a reusable modules library to standardize and accelerate infrastructure provisioning across all cloud accounts
- ▸ Set up Prometheus and Grafana for production monitoring; diagnosed a critical outage by tracing a memory leak through metrics and logs, coordinated the fix with the backend team, and added service-level CPU/memory limits and alerting to prevent recurrence
- ▸ Built custom Grafana dashboards tracking API Gateway metrics — request rate, response time, response size, and rate-limit violations — with threshold-based alerting to surface performance issues early
- ▸ Deployed Jaeger for distributed tracing, providing end-to-end visibility into request flows across services and making latency bottlenecks and failure points traceable
- ▸ Designed and validated a disaster recovery strategy: configured deletion protection, DynamoDB backups, and AWS Backup; ran a full DR simulation achieving RTO of 16 min (target: 20 min) with RPO of 24 hours
- ▸ Cleared a storage crisis on production instances — from 90–93% down to 53–55% — by purging stale deployment artifacts and tightening revision retention, preventing future deployment failures
- ▸ Introduced Ansible for post-provisioning configuration, automating Nginx/SSL setup, package installs, and environment variable management across environments and eliminating manual SSH access
- ▸ Integrated database migration execution into the CI/CD build phase, ensuring schema changes are applied before application startup and preventing environment drift
- ▸ Migrated the production email system to AWS SES and refactored the sending layer with connection pooling and parallel processing, improving throughput and removing reliability bottlenecks
- ▸ Automated dev/staging environment shutdowns outside business hours, cutting compute costs by ~45–50%
⚙ Tech Stack:
★ Achievements:
- ✓ Achieved RTO of 16 min (vs. 20 min target) in full DR simulation with 24h RPO
- ✓ Migrated 12+ manually created AWS resources into reusable Terraform modules across dev/staging/prod
- ✓ Cut compute costs by ~45–50% through scheduled non-production shutdowns
- ✓ Cleared production storage from 90–93% to 53–55% utilization, preventing deployment failures
- ✓ Diagnosed and resolved a critical production memory leak through Prometheus/Grafana observability
