Monthly AWS spend reduced by 34% ($8,200/month savings) within 45 days.

Post-incident response: suspicious activity detected in AWS account, unclear scope of compromise.

• Contained threat by rotating credentials and isolating affected resources
• Analyzed CloudTrail logs to determine blast radius
• Implemented GuardDuty, Security Hub, and enhanced IAM policies
• Created incident response runbook for future events

Threat contained within 4 hours. Zero data exfiltration confirmed. Security posture hardened with continuous monitoring.

60-person company running on aging on-premise servers with end-of-life hardware approaching.

• Assessed 12 applications and 8 servers for migration readiness
• Designed AWS landing zone with VPC, networking, and security baseline
• Migrated workloads in 4 phases over 6 weeks
• Maintained site-to-site VPN during hybrid period

Full migration completed with zero data loss and 2 hours total planned downtime across all phases.

VPC designed 3 years ago with flat network, no segmentation, and IP exhaustion looming.

• Redesigned VPC architecture with proper subnet tiers (public, private, data)
• Implemented network ACLs and security group cleanup (removed 180+ unused rules)
• Built new VPC in parallel and migrated traffic incrementally

Zero-downtime network redesign. Proper segmentation with 10x IP capacity for growth.

Dev and staging environments running 24/7 costing $4,500/month despite only being used during business hours.

• Implemented automated scheduling (stop at 7pm, start at 7am weekdays)
• Right-sized dev instances from m5.xlarge to t3.medium
• Moved staging databases to Aurora Serverless

Non-production costs reduced by 68% ($3,060/month saved). Zero impact on developer productivity.

43 IAM users with admin-level access, no MFA enforcement, shared credentials across teams.

• Audited all IAM policies and mapped actual required permissions
• Implemented least-privilege policies for every user and role
• Enforced MFA across all accounts
• Deployed AWS SSO for centralized access management

100% MFA coverage. Admin access reduced from 43 users to 3. Access now managed through SSO with audit trail.

Deployments done manually via SSH, taking 2+ hours each and occasionally causing outages.

• Built CI/CD pipeline with GitHub Actions
• Implemented blue-green deployment strategy on ECS Fargate
• Added automated testing and security scanning in pipeline
• Created rollback automation

Deployments reduced from 2 hours to 8 minutes. Zero-downtime deployments with automatic rollback capability.

Active Directory environment with 200+ users needing cloud identity without disrupting daily operations.

• Deployed AWS Managed AD with trust relationship to on-prem AD
• Configured hybrid identity with seamless SSO
• Migrated users in waves with validation at each stage
• Documented cutover and rollback procedures

Hybrid AD deployed with zero user disruption. Seamless SSO working across on-prem and cloud resources.

RDS database running single-AZ with no backups configured. Single point of failure for production application.

• Enabled Multi-AZ deployment with automatic failover
• Configured automated backups with 30-day retention
• Implemented cross-region read replicas for DR
• Created database runbook with failover procedures

99.99% database availability target achieved. RPO reduced from 'unknown' to 5 minutes, RTO from hours to 60 seconds.

Startup scaling from 10K to 500K monthly users with architecture that wasn't designed for growth.

• Redesigned application tier with auto-scaling groups
• Implemented CloudFront CDN for static assets
• Migrated from single RDS to Aurora with read replicas
• Added ElastiCache for session management

Successfully handled 50x traffic growth. P95 latency reduced from 1.2s to 180ms. Infrastructure costs grew only 3x.

Preparing for SOC 2 Type II audit with no existing security controls documentation.

• Mapped SOC 2 trust service criteria to AWS controls
• Implemented missing controls (encryption, logging, access reviews)
• Created evidence collection automation using AWS Config
• Documented all policies and procedures

Passed SOC 2 Type II audit on first attempt. Automated evidence collection reduced ongoing compliance effort by 70%.

S3 storage costs growing 20% quarterly with 14TB of data and no lifecycle policies.

• Analyzed access patterns across all S3 buckets
• Implemented Intelligent-Tiering for frequently accessed data
• Moved cold data to Glacier with lifecycle policies
• Identified and removed 3.2TB of orphaned data

S3 costs reduced by 52%. Growth trajectory flattened from 20% quarterly to 3% with proper lifecycle management.

Company needed secure connectivity between 3 office locations and AWS VPC for hybrid workloads.

• Deployed site-to-site VPN with FortiGate firewalls
• Configured BGP routing for automatic failover
• Implemented split-tunnel VPN for remote workers
• Set up monitoring and alerting for tunnel health

Secure hybrid connectivity with 99.9% uptime. Automatic failover tested and validated. Remote workers connected in under 30 seconds.

Infrastructure managed entirely through AWS console clicks. No version control, no reproducibility.

• Reverse-engineered existing infrastructure into Terraform
• Organized into reusable modules (VPC, ECS, RDS, IAM)
• Set up remote state with S3 + DynamoDB locking
• Implemented CI/CD for infrastructure changes via GitHub Actions

100% of infrastructure now defined in code. Environment provisioning reduced from days to 20 minutes. Full audit trail of every change.
