Top-Rated Plus, Expert-Vetted, Upwork Top 1 Percent, Fortune 500, Federal, Inc 5000 Thanks for reading! 🚀 I build the world's leading AI and DevOps tooling — and we bring that same engineering rigor to every Upwork engagement. I've shipped production systems for Fortune 500 enterprises, federal agencies, the U.S. military, and Inc. 5000 startups. That means the patterns we deploy for your project aren't theoretical — they're running right now in environments with real compliance requirements, real uptime SLAs, and real scale. We've designed the kind of infrastructure other teams buy as a product, and now we're making that caliber of work available to smaller teams and faster-moving projects. Here's what you get when you hire me: 🏆 BATTLE-TESTED EXPERTISE Terraform, CI/CD, LLM pipelines, observability, secure-by-default AWS architecture — the full modern cloud stack, built by people who've deployed it in regulated environments. 🤖 FRONTIER AI & DEVOPS TOOLING We build the systems other agencies resell. When you hire me, you're hiring the builders, not the middlemen. 💰 ENTERPRISE-GRADE WORK, STARTUP-FRIENDLY PRICING I'm deliberately structured to deliver senior-level results at a rate that fits real-world budgets. No big-agency markup, no junior engineers pretending to be senior. Whether you need to cut an out-of-control AWS bill, ship a CI/CD pipeline you can actually trust, stand up an AI system that solves a real business problem, or just get a second opinion from people who've seen it all — I'd love to talk about what you're building. Hire me and you're getting the expertise of a team trusted by the world's most demanding clients, at a rate that actually makes sense. Let's build something.

As an AWS-certified DevOps and cloud security engineer, I help startups, fintech companies, and AI/ML platforms build secure, compliant, production-grade AWS infrastructure — including the AI infrastructure layer most DevOps engineers haven't touched yet: LLM inference endpoints, RAG pipelines, and GPU-backed compute. With certifications in AWS DevOps Engineer – Professional, AWS Solutions Architect – Professional, AWS Security – Specialty and AWS CloudOps Engineer – Associate, your infrastructure is in capable, currently-certified hands. WHAT I DO BEST AI/ML Infrastructure on AWS I deploy fine-tuned LLM inference endpoints across GPU instance families, build RAG knowledge bases using Amazon Bedrock and pgvector, and stand up Feature Stores for ML pipelines — all on Terraform, all production-grade. If your platform runs AI workloads, I build the infrastructure underneath the model. Enterprise Cloud Foundation & Governance I establish AWS cloud foundations using Control Tower and Landing Zone with automated multi-account environments and security guardrails — Security Hub, GuardDuty, AWS Config, CloudTrail, and SCPs. This significantly eases SOC 2, ISO 27001, and HIPAA audit preparation through automated compliance evidence. Security-First Infrastructure VPC isolation, least-privilege IAM, secrets management, and encryption everywhere. A recent project passed a SOC 2 audit with zero infrastructure findings, built in from day one. Cloud Migrations & Containerization I migrate applications from on-premises and legacy clouds (GCP, Azure) to AWS with zero downtime — deploying to ECS/Fargate, EKS, or traditional EC2, with a focus on cost efficiency and security. Infrastructure as Code Everything is Terraform-based, version-controlled, and reproducible — multi-account Control Tower setups, VPC architectures, IAM policies, all defined as code with peer review. CI/CD & Production Reliability Deployment pipelines (GitHub Actions, GitLab CI, AWS CodePipeline) that cut deployment time from hours to minutes, with automated testing and rollback. Designed for 99.99% uptime through Multi-AZ deployments and auto-scaling. RECENT RESULTS - Architected GCP-to-AWS migration for an AI/ML fintech platform — 5 fine-tuned LLM inference endpoints across GPU instance families, RAG knowledge base on pgvector, full Terraform IaC - Deployed a containerized Spring Boot app on ECS Fargate with Control Tower multi-account setup, Security Hub, GuardDuty, Config, and CloudTrail across dev/staging/prod - Migrated a payment platform to AWS — 99.99% uptime, handled 10x traffic spikes, 40% cost reduction - Delivered enterprise Landing Zone migration framework for 85 applications, 450 VMs, 55 databases - Automated deployments from 2 hours to 15 minutes with improved security posture TECH STACK AWS AI/ML: Amazon Bedrock, Amazon SageMaker, RAG pipelines, pgvector, Feature Store, GPU instances AWS Governance & Security: Control Tower, Organizations, Security Hub, GuardDuty, Config, CloudTrail, IAM, Secrets Manager, KMS, WAF AWS Infrastructure: ECS/Fargate, EC2, Lambda, RDS, DynamoDB, S3, VPC, CloudFront, ALB/NLB, Auto Scaling Containers & Orchestration: Docker, ECS/Fargate, Kubernetes/EKS, ECR Infrastructure as Code: Terraform (5+ years), CloudFormation, AWS CDK CI/CD: GitHub Actions, GitLab CI, Jenkins, AWS CodePipeline/CodeBuild/CodeDeploy Databases: RDS (PostgreSQL, MySQL, SQL Server), DynamoDB, MongoDB/DocumentDB Monitoring: CloudWatch, CloudTrail, VPC Flow Logs, Security Hub, Config Scripting: Python, Bash, Shell WHO I WORK WITH - AI/ML platforms needing production-grade inference and RAG infrastructure - Startups preparing for SOC 2 certification - Fintech companies needing secure infrastructure for financial data - Healthcare/SaaS companies requiring HIPAA-ready environments - Companies migrating from on-premises, GCP, or Azure to AWS - Enterprises needing multi-account AWS governance WHAT MAKES ME DIFFERENT Most DevOps engineers deploy applications. I build enterprise security foundations — and the AI infrastructure layer most of them haven't touched yet. You get: ✓ AI/ML infrastructure built by someone who understands both the model and the cloud underneath it ✓ Security and compliance built in from day one ✓ Automated audit evidence collection ✓ Multi-account governance preventing drift ✓ Clear documentation and knowledge transfer Looking for secure, audit-ready AWS infrastructure — or AI/ML platform infrastructure that actually scales? Let's talk.

At this point probably you've already read dozens of AI-generated or copy-pasted "100% Job success, Top Rated 👑" profiles overviews of other freelancers and I bet you don't want to read another one. To make it short - I'm proficient at AWS as Solutions Architect and DevOps, worked with all the main services, including AI/ML (such as Bedrock, Rekognition, Textract, etc.); also I have a big experience with PHP backends and Python. Key points: * Doing things in a proper way is my priority. E.g. I will never create static AWS IAM key for an app running on EC2 instance, even if your dev team insists on that (probably simply because they don't have enough expertise) - the proper way to do that is to leverage IAM roles, because this is much more secure. I already had several customers suffering from conflicts with their dev teams where dev teams simply destroyed their setup, because they had static IAM keys, while with IAM roles that would be impossible * I always support my customers after the contract is ended. I cannot do 24/7 support, but believe me, in case of any issue, I'll respond as soon as possible * If you hire me for resolving some bug/issue and it's not resolved by me - I won't charge you. Please note, that this applies to initially described bug/issue; in a situation when there is a next bug appears after the first one is fixed - I'll let you know if I can solve it or no and what will be an additional cost (typical example - after the fix of SSL issue it turns out that site is not working due to some mistakes in code - this is different issue, not related in any way to the first one) * I'm not a good fit for any job that requires 24/7 support even with rotation - even though I'm responding as fast as I can - I cannot always guarantee that * I can work via screenshare, but that's not as efficient as direct access, and therefore will be more expensive as more time will be spent Thanks for reading this and looking forward to our collaboration.
