Hire the Best Cluster Computing Developers

The engineer you call when software, infrastructure, and networking all need to work together. 🚀 Senior DevOps Engineer | Backend Developer | Cloud & Platform Engineer Most technical problems don't exist in a single layer. An application is slow, but the root cause is the database. A deployment fails because of infrastructure. An API works locally but breaks in production because of networking. AI features underperform because the data pipeline was designed incorrectly. My background spans software development, cloud infrastructure, Linux systems, networking, automation, and AI integrations, allowing me to build and troubleshoot systems end-to-end. Over the last 5+ years, I have worked across AWS, GCP, Kubernetes, Docker, Terraform, CI/CD automation, backend APIs, distributed systems, AI-powered applications, and production environments supporting real business operations. 🎯 What I Can Help With ✅ Backend Development (Node.js, Python, Go, .NET) ✅ Cloud Infrastructure (AWS, GCP) ✅ Infrastructure as Code (Terraform) ✅ Kubernetes & Docker Platforms ✅ CI/CD Automation (GitHub Actions, GitLab CI, Jenkins) ✅ Linux Administration & Troubleshooting ✅ Database Design & Optimization ✅ AI & LLM Integrations (OpenAI, RAG, AI Agents) ✅ Monitoring, Observability & Reliability Engineering ✅ Performance Optimization & Cloud Cost Reduction 🔧 Clients Typically Bring Me In For • Building platforms that require both development and infrastructure expertise • Solving production issues that span applications, databases, networking, and cloud services • Modernizing deployment workflows and DevOps practices • Designing scalable cloud-native architectures • Integrating AI capabilities into existing products • Reducing operational complexity and cloud costs 💻 Core Technologies ☁️ Cloud AWS • GCP • Azure ⚙️ Infrastructure Terraform • Docker • Kubernetes • ECS • EKS • Linux 🖥 Backend Node.js • Python • Go • .NET • FastAPI 🌐 Frontend Next.js • React • TypeScript 🗄 Databases PostgreSQL • MySQL • MongoDB • Redis 🚀 DevOps GitHub Actions • GitLab CI • Jenkins • Monitoring • Observability 🤖 AI OpenAI • LLM Integrations • RAG Systems • AI Agents 💡 I work best with startups, SaaS companies, and engineering teams that need a single engineer capable of owning systems end-to-end—from architecture and development to deployment and operations. 🟢 If your project involves software, infrastructure, automation, or AI, let's talk.

Your infrastructure breaks at 2 AM. Your deploys take 45 minutes. Your AWS bill climbed 40% and nobody can explain why. I fix all three - and I've done it 100+ times on this platform. Former SRE Lead at Yellow AI (100M+ users, AWS + on-prem). Now I run Skybyte, a DevOps and cloud consulting practice focused on startups and mid-market teams that need senior infrastructure work without the senior hire. What 61+ Upwork jobs and a 100% Job Success Score actually look like: Cloud cost optimization - cut AWS/Azure/GCP spend by 40-60% through right-sizing, Reserved Instances, spot fleets, and architecture cleanup. Not guesswork; I run the cost audit, build the dashboard, and hand you the savings. Kubernetes migration and management - moved production workloads to EKS, AKS, and self-managed clusters on Hetzner. Helm charts, ArgoCD GitOps, zero-downtime cutovers. I've handled clusters running 200+ pods and clusters running 6. CI/CD pipeline engineering - GitHub Actions, GitLab CI, Azure DevOps Pipelines, Bitbucket Pipelines. Took teams from 45-minute manual deploys to sub-5-minute automated releases with rollback built in. Infrastructure as Code with Terraform - full AWS, Azure, and GCP environments defined in Terraform modules. State management, drift detection, and PR-based infrastructure reviews that your team can maintain without me. DevSecOps and compliance - SOC 2 infrastructure from scratch, cloud security audits, Cloudflare WAF and DDoS protection, network security architecture, and DPDP-aligned data handling. I've built the controls and written the documentation auditors actually accept. Monitoring, observability, and SRE - Prometheus, Grafana, OpenTelemetry, Datadog, PagerDuty. Full observability stacks that catch failures before your users file tickets. I set up SLOs, runbooks, and on-call workflows. Beyond core DevOps - SSO/SAML integration, n8n workflow automation, MLOps pipelines, Docker deployments on bare metal and VPS, GCP Cloud Run serverless, and technical documentation your team won't ignore. I work best with funded startups burning money on cloud, engineering teams stuck in deployment hell, and companies scaling past the point where one developer can manage the infrastructure part-time. Stack: AWS (EKS, EC2, Lambda, RDS, S3) · Azure (AKS, DevOps, AD) · GCP (GKE, Cloud Run) · Kubernetes · Helm · Terraform · Docker · GitHub Actions · GitLab CI · ArgoCD · Prometheus · Grafana · OpenTelemetry · Datadog · Cloudflare · n8n Not a "set it up and disappear" contractor. I document everything, train your team, and build systems designed to run without me and scale.

Hey, Choudhry here. Most freelancers either build AI agents or they deploy infrastructure. I do both. So when your project hits the messy handoff between the two, and it always does, nothing breaks. That seam is where most builds fail, and it’s the reason you’re reading past the first line. I build the infrastructure that takes AI from notebook to production, the agents that run on it, and the full-stack platforms that wrap around both. Currently Acting CTO at Peregrine Ventures AI and Building an awesome product Deplexify. Previously shipped production systems at SINO-PAK Center of AI, TCEngine AI, Nestbox and KAUST Supercomputing Labs for Shaheen III. A quick filter: if you want the cheapest bid, I’m not it. If you want it built once, correctly, by someone who owns the outcome, keep reading. 🚀 What I deliver LLM Serving & GPU Infrastructure vLLM optimization, NVIDIA Triton, multi-GPU tensor parallelism, MIG scheduling on H100/A100, Kubeflow pipelines, GPU memory profiling. Kubernetes Platforms Bare-metal K8s on Proxmox/Rancher (Calico, MetalLB, HAProxy), managed K8s on GKE/EKS/AKS, GitOps via ArgoCD, IaC via Terraform/Ansible/Pulumi.

I’ll tell you upfront if I’m not the right fit, because a clean no saves us both weeks. Recent client feedback says it better than I can: “He single-handedly built our Kubernetes infrastructure for our GPU setup and the end-to-end pipeline. A full stack AI guy.” “Energetic, hungry, and sharp. When he says he’s gonna do something by a deadline, he does it. Owns accountability.” “Worked late into the night to get it done. Delivered what he promised.” Fixed-price for scoped work, hourly for ongoing engagements. Tell me what you’re building. I’ll come back with a frank read on whether I can help and what it’ll take.
