Usama Munawar, Full-Stack Product Engineer for React, Node.js & Laravel

Full-Stack Product Engineer helping founders, startups, and product teams ship React web apps, React Native mobile apps, Node.js services, and Laravel/PHP backends. 5+ years building production systems with TypeScript and PHP, with verified profiles on Upwork and Fiverr.

What I Build

I architect and ship complete products: accessible React web interfaces, React Native apps for iOS and Android, typed Node.js services, and scalable Laravel/PHP application cores with billing, RBAC, audit trails, APIs, queues, and zero-downtime deployments.

I build self-hosted call centers on Asterisk and FreePBX, IVR flows, predictive dialers, SIP trunking, and CRM-integrated call workflows, plus real-time systems on Laravel Reverb, Pusher, and Socket.IO for presence, live dashboards, and chat.

On the automation and AI side, I ship n8n workflows, MCP agents, RAG pipelines on Pinecone and pgvector, and Claude/GPT-4 integrations wired safely into existing Laravel and Node backends with proper guardrails, evaluation harnesses, and observability.
