Hi! I’m an AWS-certified DevOps Engineer and Solutions Architect helping SaaS companies build, secure, modernize, and scale production systems on AWS. I have 7+ years of backend engineering experience and 5+ years of AWS cloud engineering experience. CERTIFICATIONS * AWS Certified Solutions Architect – Associate * AWS Certified DevOps Engineer – Professional * AWS Certified Solutions Architect – Professional My main advantage is that I understand both AWS infrastructure and backend applications. You do not need to hire separate cloud, DevOps, security, and backend engineers to solve one production problem. WHAT I CAN HELP YOU WITH 1. AWS PLATFORM MODERNIZATION AND GOVERNANCE * AWS Organizations, Control Tower, Landing Zone, SCPs, and IAM Identity Center * Multi-account architecture with separate development, staging, and production environments * ECS, EKS, Lambda, and serverless architecture * Centralized logging, account governance, and platform standards 2. INFRASTRUCTURE AS CODE AND CI/CD * Terraform, CloudFormation, and AWS CDK * Reusable modules and infrastructure migration * Terraform import, state management, and drift remediation * CI/CD implementation and optimization * GitHub Actions, CodePipeline, CodeBuild, and CodeDeploy 3. AWS SECURITY, NETWORKING, AND COMPLIANCE * IAM least-privilege access and security reviews * VPC design, subnets, routing, NAT Gateway, and VPC endpoints * Security groups, network ACLs, segmentation, and private connectivity * Security Hub, GuardDuty, Inspector, AWS Config, CloudTrail, and KMS * Secrets management, encryption, backup, and recovery * Technical remediation for SOC 2, ISO 27001, Vanta, Drata, and Sprinto I provide practical implementation, not only an audit report. 4. AWS FINOPS AND COST OPTIMIZATION * EC2, ECS, EKS, Lambda, and RDS right-sizing * Savings Plans and Reserved Instance planning * NAT Gateway, storage, data transfer, and CloudWatch cost optimization * Cost allocation tags, budgets, and anomaly detection My process is simple: Analyze → Implement → Measure → Monitor 5. FRACTIONAL AWS ENGINEERING, MIGRATION, AND RELIABILITY I can support SaaS teams for 10–20 hours per week with: * AWS architecture and production change reviews * Monitoring, incident investigation, and reliability improvements * Cloud and database migrations * High availability, backup, RTO, RPO, and disaster recovery * Backend and database troubleshooting 6. AWS AI AND MACHINE LEARNING INFRASTRUCTURE * Amazon Bedrock and foundation model integration * Amazon SageMaker AI infrastructure and model deployment * Amazon Textract, Rekognition, Transcribe, Polly, and Comprehend * Secure IAM, private networking, and model access controls * AI workload monitoring, governance, and cost optimization WHY WORK WITH ME I can work across the complete production system: * AWS architecture, networking, security, and Infrastructure as Code * Go, Java, Spring Boot, and APIs * PostgreSQL, Redis, and Elasticsearch * Containers, CI/CD, monitoring, and production troubleshooting You work directly with a senior engineer who can assess the problem, recommend the right solution, implement it, and support it in production.
