Nasir I.

Backend and DevOps engineer, 9+ years in production, now putting AI into systems that already run a business. On Upwork: 69 contracts, $100K+ earned, 100% Job Success, Top Rated Plus. Retained by four clients today, two of them past 500 hours each. WHAT I AM HIRED FOR NOW - AI-built apps to production. Your MVP came out of Lovable, Bolt or Claude Code and now needs auth, permissions, tests and a deployment that holds. I productionised a multi-tenant React, Express and Postgres platform for a Swiss health-tech company over 520+ hours, and spent 146 hours as a software engineer in test and API security engineer before that. - Claude Code on your existing codebase, with guardrails. Hooks, permission settings, a claim-checking agent before anything goes out, one workspace per project. I built that system for a cloud consultancy that runs nine enterprise engagements on it, and I train teams on it (5 stars, "an excellent expert in AI"). - AI connected to the systems you already have. MCP servers over SQL Server, Postgres, CRMs and ERPs, read-only first, write actions after approval. A real-estate operator's private Claude assistant runs on this: 200 to 300 inbound messages a day through their CRM. - Infrastructure for AI platforms. Bicep and GitHub Actions deployment for a Fortune 500 manufacturer's internal AI assistant (about 500 users): Azure AI Search, AI Foundry, private endpoints, Key Vault, managed-identity RBAC, Entra ID sign-in. - Plain backend and DevOps. A FastAPI actuarial data API with Azure DevOps pipelines for a reinsurer, a Terraform landing zone and tenant-consolidation work for a manufacturer, a demand-forecast pipeline over 41,000 SKUs for a US apparel brand. Many of my earlier contracts are Java game-server work: plugins, mods and tuning for repeat clients, including a network of 500+ daily players where I raised sustained TPS from 15 to 19.8 through JVM tuning and rewriting hot paths. Real-time systems, performance, and users who notice every lag spike. Those reviews are below; the same clients kept coming back. STACK - Backend: Python (FastAPI), Java, TypeScript (Node, Next.js), Postgres, SQL Server - DevOps: Azure, Terraform, Bicep, Azure DevOps, GitHub Actions, Docker, Linux - AI: Claude and OpenAI APIs, MCP, RAG, agents with approval steps, Claude Code for teams Small paid first slice before a larger commitment. Written handover on every engagement. Nothing changes in production without your go-ahead. Based in India, working US hours daily.
