🚀 Full-Stack Developer & AWS/DevOps Engineer | Cloud Infrastructure • Automation • Web Apps Need someone who can build your application and set up the cloud infrastructure to run it reliably? I do both — so you get one person who understands the whole picture, from the code to the servers it runs on. 🔹 What I Can Do for You ☁️ Cloud Infrastructure & DevOps — I design and deploy production-grade AWS architectures: multi-AZ setups for high availability, auto-scaling, managed databases, and disaster recovery. Everything as code with Terraform, so it's reproducible and version-controlled. 📐 Cloud Architecture & Diagrams — I design AWS architectures and produce clear, professional diagrams that show exactly how your system works — components, data flow, failover behavior, and cost breakdown. Useful for planning, client sign-off, team onboarding, and documentation. 🔄 CI/CD Pipelines — I build automated deployment pipelines (Bitbucket Pipelines, Docker, ECR) so your team ships code safely with zero-downtime deploys and easy rollbacks. 🌐 Web Apps & APIs — Fast, secure, scalable applications built with Laravel, Node.js, React, and Vue. ⚙️ Automation — Smart workflows that eliminate repetitive work, from data pipelines to business process automation. 🔗 Data & Integrations — I connect your tools, organize your data, and make sure everything works together seamlessly. 🌟 Why Work With Me? I'm not just a developer or just a cloud engineer — I bridge both. That means I can architect the infrastructure, build the application, and wire up the deployment pipeline as one coherent system. No handoffs, no gaps, no "that's not my department." I focus on infrastructure that's: 💪 Resilient — survives failures with automated recovery 🔁 Reproducible — defined as code, documented, version-controlled 💰 Cost-effective — right-sized, not over-provisioned 📄 Well-documented — architecture diagrams and runbooks so you (or your team) always understand how the system works and how to operate it 📐 Architecture & Documentation I don't just build infrastructure — I make it understandable. For every project I deliver clear AWS architecture diagrams showing components, networking, failover behavior, and estimated monthly cost. This helps clients make informed decisions, get stakeholder sign-off, and onboard their teams without guesswork. When designing systems, I often present staged options — from a lean MVP setup to a fully resilient multi-AZ production architecture — so you can choose the right balance of cost and reliability for where your business is now. 🛠️ Technical Expertise ☁️ Cloud & DevOps ✔️ AWS: EC2, ECS/Fargate, RDS, ElastiCache, S3, ALB, VPC, Lambda, API Gateway, CloudWatch, Secrets Manager ✔️ Infrastructure as Code: Terraform (reusable modules, multi-environment setups) ✔️ CI/CD: Bitbucket Pipelines, Docker, ECR, automated testing & deployment ✔️ Cloud architecture design & diagramming ✔️ High-availability architecture: Multi-AZ, auto-scaling, load balancing, disaster recovery ✔️ Monitoring & cost optimization 🖥️ Backend ✔️ Laravel, Node.js, Python ✔️ Web Scraping & Automation (Python) ✔️ Databases: MySQL, DynamoDB, Elasticsearch/OpenSearch ✔️ API Development & Testing (Postman) 🎨 Frontend ✔️ JavaScript, React, Vue.js, jQuery ✔️ HTML, CSS, Tailwind, Bootstrap ✔️ Data Visualization: Chart.js, Kibana ⚙️ Automation ✔️ Zapier, n8n, Go High Level (CRM automation), Email Automation 🧰 Tools ✔️ Git, Bitbucket, Linux
