Hire the Best CI/CD platforms Freelancers
in India

I’m a DevOps & Cloud Engineer with 5+ years of experience building, automating, and maintaining production infrastructure across AWS, GCP, Kubernetes, and modern CI/CD environments. I help startups and businesses turn manual, unreliable infrastructure into automated, secure, and scalable platforms. 🚀 WHAT I CAN HELP YOU WITH • AWS Cloud Infrastructure EC2, VPC, IAM, ALB, Auto Scaling, RDS, S3, Route 53, CloudWatch, Lambda, EKS and other AWS services. • Kubernetes & Containerization Docker, Kubernetes, Amazon EKS, GKE, cluster setup, application deployment, scaling, troubleshooting, Helm and production workload management. • CI/CD & Deployment Automation Jenkins, GitHub Actions and automated build, test and deployment pipelines with reliable release and rollback strategies. • Infrastructure as Code Terraform, CloudFormation and Ansible to provision repeatable, version-controlled infrastructure instead of manual configuration. • Cloud Migration On-premises/VPS applications and workloads migrated to AWS/GCP with a focus on security, availability and minimal downtime. • Monitoring & Reliability CloudWatch, Prometheus, Grafana, logging, alerting, troubleshooting and production incident resolution. • DevOps Automation Python, Bash and PowerShell automation to eliminate repetitive operational tasks and improve engineering efficiency. 🔐 SECURITY-FIRST APPROACH I follow DevSecOps principles including IAM least privilege, secrets management, secure networking, infrastructure hardening and security checks within deployment workflows. 🎯 TYPICAL PROBLEMS I SOLVE ✓ “Our deployments are still manual.” ✓ “Our AWS infrastructure is difficult to maintain.” ✓ “Our Kubernetes cluster keeps breaking.” ✓ “We need Terraform instead of manual AWS configuration.” ✓ “Our CI/CD pipeline is slow or unreliable.” ✓ “We need to migrate our application to AWS.” ✓ “We need monitoring and alerting for production.” ✓ “Our infrastructure needs to be more secure and scalable.” 💡 WHAT YOU GET ✔ Production-ready infrastructure ✔ Infrastructure delivered as code ✔ Automated CI/CD pipelines ✔ Docker/Kubernetes deployment ✔ Security-conscious architecture ✔ Monitoring and documentation ✔ Clean, maintainable automation ✔ Clear communication throughout the engagement If you already have infrastructure, I can troubleshoot and improve it. If you're starting from scratch, I can design and build the DevOps foundation for you. Send me your current architecture, deployment problem, or infrastructure requirement, and I’ll help you identify the best approach.

If your cloud environment grew faster than your security did — IAM roles nobody's audited in a year, Terraform that's never been scanned, containers running images nobody's checked — I can fix that without slowing your team down. Here's what I can do for you: 🔐 Find out what's actually exposed. I'll audit your AWS/GCP IAM, network rules, and Terraform for misconfigurations before an attacker or an auditor does. You get a clear list of what's risky and what to fix first — not a 40-page report you'll never read. 🛡️ Catch problems before they ship. I'll wire security scanning into your CI/CD pipeline — IaC checks, container image scanning, dependency scanning — so misconfigurations get caught in a pull request, not in production. ☸️ Harden your Kubernetes. Image hardening, admission controls, runtime detection, network policies — so a compromised container can't quietly become a compromised cluster. 🔑 Fix your IAM before it becomes an incident report. Least-privilege access, service account cleanup, secrets out of code and into proper management — the unglamorous work that actually stops breaches. 📊 Give you visibility you don't have to chase. Monitoring and alerting (Prometheus, Grafana, CloudWatch) tuned to actually tell you something's wrong, not bury it in noise. ⚙️ Do it without breaking what already works. I come from production DevOps, not a security-only background — I know what it costs a team when a "fix" takes down a deploy pipeline, so I build security in a way you can actually live with. A COUPLE OF RESULTS FROM PAST WORK At one company, I was the first infrastructure hire and inherited a setup with no IAM discipline and no TLS standardization — I rebuilt it from scratch and cut incident resolution time 40% in the process. At another, tightening cloud resource and access controls cut monitored cloud waste up to 35%, while streamlining the pipeline around it cut release time 60%. WORTH KNOWING UPFRONT My depth is strongest in AWS/GCP-native security, Terraform-based IaC, and Kubernetes/container hardening. I don't currently have production experience with CloudFormation, ARM templates, Windows Server hardening, or enterprise Zero Trust platforms (ZTNA/SASE/PAM/XDR vendors like Zscaler or CyberArk). If your project needs those specifically, I'll say so upfront rather than figure it out on your dime. HOW I WORK I test, monitor, and document before I call anything done. You'll always know where things stand — no jargon dumps, no radio silence. I prefer 6+ month engagements because that's how security actually gets fixed, not patched. Tell me what you're running and where it hurts, and I'll tell you honestly what I'd do about it.

I build production-ready web applications from the ground up, combining modern front-end experiences with scalable back-end systems, secure APIs, and reliable cloud deployments. Whether you need a SaaS product, an internal business tool, a customer portal, or an AI-powered application, I can take it from idea to production. 💻 WHAT I DO • Build responsive, high-performance web applications using React, Next.js, TypeScript, and Tailwind CSS • Develop scalable back-end systems with Node.js, Python (FastAPI), Express, and PostgreSQL/Supabase • Design secure REST APIs with JWT authentication, OAuth, role-based access control, rate limiting, and robust input validation • Integrate third-party services, payment gateways, AI platforms, CRMs, and external APIs • Design efficient database schemas and business logic that scale as your product grows • Deploy applications using Vercel, AWS, Docker, CI/CD pipelines, and modern cloud infrastructure 🛠 MY APPROACH I believe great software isn't just about writing code. It's about building systems that are secure, maintainable, and designed for real users. Every application I build is developed with scalability, performance, and security in mind from day one. That includes clean architecture, reliable API design, proper authentication, encrypted data transmission, and proactive handling of edge cases before they become production issues. Instead of treating the front end and back end as separate pieces, I build them as one cohesive system that works seamlessly together. ✅ WHY WORK WITH ME • End-to-end ownership, from UI development to backend architecture, APIs, databases, and deployment • Clear communication and regular progress updates throughout the project • Clean, maintainable code that's easy to extend as your business grows • Proactive identification of risks, bottlenecks, and edge cases before they become costly problems • A focus on building reliable products, not just completing tasks If you're building a web application and want someone who can own the entire development process, let's talk. Tell me what you're building, and I'll give you an honest assessment of the best technical approach to bring it to life.
