Most clients find me after wasting weeks on engineers who deploy fast but leave security gaps, brittle scripts, and zero documentation behind. Well, I do the opposite. I'm a DevSecOps engineer with 7+ years building cloud infrastructure that is production-hardened from day one, not secured as an afterthought. AWS, Kubernetes, CI/CD, secrets management, container security, GDPR-compliant workflows, all of it built clean and documented properly. I'm also one of the few engineers who builds AND secures AI agent systems.

You coded a working app on Replit, Lovable, or Base44 over the weekend. That part was easy. Then real paying customers showed up, and the setup that was fine for a demo started to break. Here's the simple truth about AI app builders. They excel at one thing: quickly turning an idea into a live app. This helps you win your first test users. But that's where it ends. These tools were never designed to run a real product for thousands of paying customers. Once you get actual traffic and money, you need infrastructure that these tools cannot provide. That's what I do. I take apps built on these tools and rebuild the underlying systems on AWS. This allows the product that already works to scale to thousands of paying users without breaking or wasting money. I set up the AWS architecture, automate your deployments, and keep everything stable, secure, and cost-effective as you grow. I have built backend and cloud systems for over 10 years, recently focusing on AWS, DevOps, and Infrastructure as Code. I have also worked inside a medical-device company, where reliability, clear documentation, and compliance were crucial. What clients say: 🏅 "Jose was amazing... he provided fantastic and specific advice which I value a lot. Will surely reconnect with him." (AWS API Gateway consultation, 5 stars) 🏅 "He is an expert with Terraform and AWS. Great addition for a technical team." (AWS data pipeline, 433 hours as lead architect) 🏅 Clients call my work reliable, collaborative, and high quality. We are a good fit if you are thinking: 🔑 "We built our MVP on Lovable, Replit, or Base44, and now it cannot handle the users we are getting." 🔑 "Our app works, but it slows down or goes offline every time we get a spike." 🔑 "We need real CI/CD and Infrastructure as Code, not manual clicks just to ship." 🔑 "Our cloud bill keeps going up and no one can explain why." 🔑 "We want someone senior who documents the work and stays around after launch." Working with me, you will 🎉 Stop struggling with infrastructure that fails when real traffic arrives. Your setup will be written as code, versioned, and easy to repeat rather than assembled by hand 🎉 Have automated and safe deploys, ensuring that shipping a change is never a scary moment 🎉 Get systems that are monitored and easy to debug, allowing you to identify problems before your users notice them 🎉 Have tracked and reduced costs, so growth doesn't deplete your budget 🎉 Receive a fully documented setup, making it easy for your team to continue the work even if I'm not available A few quick stats: 📈 100% Job Success Score and Top Rated across 13 Upwork contracts, with 500+ hours logged 📈 400+ hours as lead architect on one AWS data pipeline, taken from prototype to production 📈 Four AWS certifications verified by Upwork: Solutions Architect and DevOps Engineer (Professional), plus Developer and SysOps Administrator (Associate) 📈 10+ years building software, with a recent focus on AWS and cloud Tech I work with: 🛠️ Cloud & DevOps: AWS (EC2, ECS, EKS, Fargate, Lambda, S3, RDS, API Gateway, CloudWatch, IAM), Azure 🛠️ Infrastructure as Code: Terraform, CloudFormation 🛠️ CI/CD & Containers: GitHub Actions, GitLab CI, AWS CodePipeline, Docker, Kubernetes 🛠️ Backend & Automation: Python, Bash, Golang, FastAPI, Django 🛠️ Data & MLOps: PostgreSQL, MongoDB, Redis, data pipelines, production MLOps Building the app was the easy part.
