Senior Full-Stack Developer | Scalable Architecture | Performance & Stability If your platform is struggling with latency, unstable deployments, or a codebase that’s becoming a bottleneck, I can help. I specialize in turning "scaling pains" into high-performance, predictable systems. What my 5+ years of experience bring to your team/project: Performance Optimization: I recently optimized an LMS by resolving OpenAI RAG latency. By designing a Sidecar container to handle AI streaming in parallel, I delivered real-time responses while the main backend handled data storage which massively improved the user experience. DevOps as a Standard: I utilize infrastructure as code (Terraform, Cloudformation etc) as a best practice for deployments. Whether it's AWS, GCP, or OVHcloud, I ensure your environment is version-controlled, reproducible, and scales behind automated load balancers. Bulletproof Auth & Payments: I prioritize security with HTTP-only cookie auth and have integrated complex subscription flows using Stripe and Square. Zero-Downtime Releases: I implement CI/CD pipelines that allow you to ship code with a single trigger that require no maintenance windows, no user interruptions. 🛠 The Toolkit Backend: Node.js (Fastify/Express), Python (Django/FastAPI), Supabase, Parse Server. Frontend: React, Next.js, Angular, TypeScript, Tailwind CSS. Infrastructure: Docker, Kubernetes, Terraform, AWS, Redis. Real-Time: WebSockets, NATS, MQTT. The Bottom Line: You get clean, maintainable code, measurable speed improvements, and a partner who understands the "founding team" hustle. I’m available to start immediately and operate with a high-availability mindset. Let's hop on a call and discuss further.

If your cloud infrastructure, CI/CD pipelines, data workflows, or ML deployments are becoming difficult to manage, insecure, or hard to scale, I can help you build a reliable, automated, and production-ready system. I’m a DevOps, MLOps, and Cloud Engineer with 4+ years of hands-on experience designing, deploying, and maintaining secure cloud infrastructure across AWS, Azure, and Google Cloud Platform. I help startups and growing companies automate deployments, manage Kubernetes environments, optimize cloud operations, and deploy AI/ML systems with scalable DevOps practices. My work focuses on building systems that are secure, scalable, cost-efficient, observable, and easy to maintain. Here’s how I can help: DevOps Engineering & CI/CD Automation I build and optimize CI/CD pipelines using GitHub Actions, GitLab CI, Jenkins, AWS CodePipeline, and Bitbucket pipelines. I help teams automate deployments, reduce manual errors, improve release speed, and create reliable workflows across development, staging, and production environments. Cloud Infrastructure on AWS, Azure & GCP I design and manage cloud infrastructure using AWS, Azure, and GCP, including compute, networking, storage, IAM, databases, load balancing, certificates, secrets, monitoring, and security services. I also work with infrastructure automation using Terraform and AWS CDK. Kubernetes, Docker & GitOps I deploy and manage containerized applications using Docker, Kubernetes, ECS, EKS, Helm, and Argo CD. I can help with Kubernetes cluster operations, Helm chart development, GitOps workflows, autoscaling, ingress, secrets management, and production-grade deployment strategies. MLOps & AI Infrastructure I support AI/ML and GenAI workloads by deploying and managing ML models, RAG and non-RAG workflows, and AI infrastructure using tools like Azure AI Foundry, Kubernetes, cloud storage, APIs, and CI/CD automation. I help teams move ML workloads from experimentation to stable production environments. Data Engineering & Workflow Automation I build and automate data workflows using Python, AWS Lambda, S3, DynamoDB, API Gateway, databases, Kafka-based workflows, DAG pipelines, and cloud-native data services. I can help automate manual tasks, improve data reliability, and connect systems through scalable backend workflows. Cloud Security & Compliance Support I implement security best practices across cloud environments, including IAM hardening, Secrets Manager, AWS Security Hub, GuardDuty, Inspector, WAF, vulnerability scanning, and secure CI/CD practices. I also have experience working with compliance-focused environments, including PCI DSS. Monitoring & Observability I set up monitoring, logging, alerting, and dashboards using Prometheus, Grafana, AWS CloudWatch, Datadog, New Relic, and Uptime Robot. I help teams detect issues early, reduce downtime, and improve visibility across applications and infrastructure. I don’t just configure tools. I build complete cloud and DevOps systems that help businesses deploy faster, reduce operational risk, improve security, and scale with confidence.
