Cloud Architect and Senior DevOps Engineer with 6+ years building, migrating, and operating AWS and Azure platforms for startups and enterprises.
I help teams design scalable, secure, cost-optimized cloud architecture and deliver reliable CI/CD so features ship faster with fewer incidents.
My focus areas include Kubernetes (AKS/EKS), Docker, Terraform, Ansible, Helm, GitHub Actions, GitLab CI, Azure DevOps, and automated environment promotion (dev/uat/prod) with blue-green and canary strategies. I architect VPC/VNet networking, subnets, routing, NAT, VPN/peering, security groups/NSGs, WAF/App Gateway, private endpoints, and zero-trust IAM/RBAC/ABAC. I implement observability with CloudWatch, Azure Monitor, Prometheus, Grafana, OpenSearch/ELK, structured logging, metrics, tracing, SLO/SLAs, runbooks, and alerting. I also handle HA/DR, backups, replication, failover, and disaster recovery testing.
On AWS I work daily with EC2, EKS, ECS/Fargate, Lambda, API Gateway, RDS/Aurora, DynamoDB, ElastiCache/Redis, S3, CloudFront, Route 53, SES/WorkMail, IAM, KMS, Parameter Store/Secrets Manager, CloudWatch, CloudTrail, CodePipeline/CodeBuild, and CloudFormation. On Azure I deliver AKS, App Services, Functions, API Management, Storage, SQL/PostgreSQL for Azure, Traffic Manager/Front Door, Application Gateway/WAF, Monitor/Log Analytics, Key Vault, Entra ID SSO, Virtual Network, and ARM/Bicep.
I write infrastructure as code with Terraform, Ansible, CloudFormation, and ARM/Bicep for reproducible, reviewable, policy-guarded deployments. I containerize legacy apps, design microservices, create secure ingress with Nginx, tune autoscaling (HPA/VPA/pod disruption budgets), and optimize images and build pipelines for speed and reliability.
Recent work includes a legal AI platform on AKS with multi-environment CI/CD, secure ingress, HPA tuning, and deep observability; cloud-to-cloud cPanel migrations; email infrastructure on AWS; and adoption of open-source collaboration tools.
I built a Grafana Dashboard Schema Tool to auto-generate dashboards from infra metadata, improving visibility and reducing manual effort. I routinely run cost reviews and FinOps optimization: right-sizing, storage tiering, autoscaling policies, CDN/caching, reserved/savings plans, and spend forecasting.
How I engage:
Clear scoping and architecture diagrams, IaC from day one, automated pipelines with tests and policy guardrails, proactive monitoring, strong documentation, and responsive communication.
I’m comfortable with regulated and security-sensitive workloads and can align to best practices like CIS Benchmarks, OWASP, least privilege, encryption at rest/in transit, and audit trails. Certifications include AWS Solutions Architect Associate, Microsoft Azure Developer Associate (AZ-204), and Red Hat Specialist in Ansible Automation.
If you need to stabilize production, accelerate releases, migrate to the cloud, harden Kubernetes, or stand up CI/CD the right way, I can help.
Core skills and keywords:
AWS, Azure, Kubernetes, AKS, EKS, Docker, Terraform, Ansible, Helm, GitHub Actions, GitLab CI, Azure Pipelines, CloudFormation, ARM/Bicep, Nginx Ingress, API Gateway, Lambda, App Services, RDS, PostgreSQL, MySQL, S3, Blob Storage, VPC, VNet, WAF, CloudWatch, Azure Monitor, Grafana, Prometheus, CI/CD, IaC, SRE, Platform Engineering, HA/DR, Security Hardening, Cost Optimization.

Free AWS audit upfront. Full refund on the first milestone if you're not satisfied.
100+ AWS migrations. Zero unplanned downtime. Cloud costs cut by up to 60%. SOC 2 passed after a 30-day security audit.
I am Ibrahim, a senior AWS DevOps engineer with 9+ years building, securing, and scaling cloud infrastructure for SaaS platforms, fintech teams, and e-commerce companies. I specialize in AWS, Kubernetes (EKS), Terraform, Docker, CI/CD pipelines, and cloud security
What I’ve already done in environments like yours:
Migrated 100+ production environments from EC2 to EKS with zero unplanned downtime. Full Kubernetes orchestration with Docker containers, Helm charts, and Terraform-managed infrastructure as code across multi-region AWS architectures.
Cut CI/CD deployment time from 4 hours to 12 minutes using GitHub Actions and GitLab CI/CD with blue-green deployment, automated rollback, and ArgoCD-driven GitOps workflows.
Reduced AWS cloud costs by 30 to 60 percent through EC2 right-sizing, spot instance strategy, auto-scaling groups, Lambda serverless optimization, and ECS Fargate consolidation. Average client savings: $4,200 per month.
Cleared 44 of 47 AWS security findings in 30 days for a fintech client. Passed SOC 2 Type I on the first attempt with full compliance controls across IAM, CloudTrail, GuardDuty, WAF, Security Hub, and AWS Config.
Built HIPAA-compliant Kubernetes infrastructure on EKS with encrypted RDS databases, VPC isolation, private subnets, and continuous compliance monitoring via Prometheus, Grafana, and Datadog.
Managed AWS EKS infrastructure for 30+ client environments with 99.9 percent uptime, zero major outages, and full observability with CloudWatch, ELK Stack, and Prometheus alerting.
Designed multi-region AWS architectures handling 50,000+ concurrent users for e-commerce and fintech platforms using EKS, CloudFront, S3, RDS, ElastiCache, and Route 53.
I'll work best with you if you are:
A SaaS or fintech team whose AWS bill keeps growing. You need DevOps cost optimization, EC2 right-sizing, and cloud infrastructure cleanup.
An engineering team that needs Kubernetes (EKS) built, secured, and maintained without a full-time DevOps hire. I handle Docker containerization, Helm charts, and container orchestration.
A CTO scaling fast who needs AWS infrastructure that will not break under load. Auto-scaling, load balancing, multi-AZ failover, and high-availability architecture.
A company preparing for SOC 2, HIPAA, or ISO 27001 compliance. I build cloud security controls, DevSecOps pipelines, and audit-ready AWS environments from scratch.
A team migrating from legacy EC2, on-premise servers, or Elastic Beanstalk to Terraform-managed, containerized infrastructure on EKS or ECS with full CI/CD automation
AWS DevOps & Cloud Security for Compliance-Ready Teams:
I'll help you build AWS cloud infrastructure that is fast to ship, hard to break, and ready for serious security and compliance demands. My core strength is turning your aws environments into secure, compliant, production-ready platforms with strong AWS cloud security, DevSecOps, and clear controls for SOC 2, HIPAA, and ISO 27001.
I work with your existing tech stack:
AWS | Kubernetes / EKS / GKE | Terraform | Ansible | Docker | CI/CD | GitLab CI/CD | GitHub Actions | CodePipeline | Prometheus | Grafana | Datadog | Security Hub | GuardDuty | WAF | Shield | IAM | CloudTrail | ELK Stack | GCP
How to Get Started:
Send me a message with a quick overview of your AWS environment, your biggest infrastructure pain point, and where you want to be in 30 days. I will reply with a clear DevOps action plan. No pitch. Just what I would do differently with your Kubernetes clusters, your Terraform configs, your CI/CD pipeline, and your cloud security posture.

Hey, glad you stopped by 👋
You’re probably here because you need someone who can take ownership and actually move your project forward, not just write code.
I’m a Full-Stack Developer with 30+ years in software engineering and 15+ years building SaaS platforms, MVP products, CRM systems, and B2B applications used in real business. Most of my work is around systems where Node.js handles backend logic and React powers fast, scalable frontends.
As a Full-Stack Developer, I typically join at different stages. Sometimes it’s an MVP for a startup that needs to move fast. Sometimes it’s an existing SaaS or CRM system that needs to scale, stabilize, or be restructured. In both cases, the goal is the same: build something that works now and won’t break later.
From a backend perspective, as a Node.js Developer, I design REST APIs, API Integration layers, and services that can handle real load. On the frontend side, as a React Developer, I build responsive interfaces using React, Next.js, and TypeScript, focusing on clarity, speed, and usability. As a SaaS Developer, I also think about things like multi-tenant architecture, performance, and what actually happens when users grow.
AI is something I integrate when it makes sense. Not as a feature for the sake of it, but as part of real workflows inside SaaS and CRM systems. That usually means connecting AI agents to backend logic, adding automation for B2B processes, or building AI-powered dashboards in React. AI Development, AI Bot integrations, and AI Agent Development are things I use when they genuinely improve the product, especially in SaaS Development and MVP stages.
In practice, I sometimes use tools like OpenAI GPT-3 and GPT-4, Claude, GitHub Copilot, Cursor AI, and ChatGPT APIs to speed up development, automate parts of workflows, or support MVP builds. They help move faster, but the core always stays in solid architecture and predictable systems.
My day-to-day stack includes React, Next.js, Angular, Vue, JavaScript, TypeScript, Redux, HTML5, CSS3, SASS, Bootstrap, Tailwind, and Material UI on the frontend, and Node.js, Express.js, Nest.js, Laravel, REST APIs, API Integration, OAuth, JWT, and WebSockets on the backend. I work with PostgreSQL, MongoDB, MySQL, Redis, and DynamoDB, and deploy systems on AWS using EC2, S3, Lambda, and CloudWatch, supported by Docker and CI/CD pipelines.
Overall, what you get is a Full-Stack Developer who understands SaaS, CRM, MVP, and B2B systems end-to-end. Someone who can step into an existing codebase, figure things out quickly, and start delivering without constant guidance.
If you need that kind of support, just message me and we’ll take it from there
