Hire the Best Vortalsoft Aspect Specialists

I build production systems where AI actually has to work — not demo it. Over 8,800+ hours on Upwork (100% JSS, Top Rated Plus), I've shipped Claude and OpenAI integrations, MCP servers connecting agents to live business data, and automation pipelines that run unattended in production — handling real users and real financial data, not sandbox traffic. ✅ AI in production — Claude & OpenAI integrated into live SaaS handling real load, plus MCP server development connecting agents to real systems ✅ Automation that doesn't silently fail — n8n & Inngest pipelines with durable execution and idempotent step writes ✅ Built for scale — Kubernetes-deployed apps maintained across 2,400+ production hours. ✅ FinTech-grade reliability — APIs and pipelines for an alternative-assets platform where correctness isn't optional ✅ End-to-end ownership — Postgres schema to Docker/Kubernetes deploy to the pager going off at 3am Core stack: TypeScript, Next.js, NestJS, PostgreSQL, Redis, Docker, Kubernetes, AWS, Claude API, LangGraph, RAG/pgvector, MCP, n8n, Inngest, Stripe/Stripe Connect, Prisma, Supabase, Shopify, Go, Kafka, Terraform. If you're integrating AI into an existing system, building an MCP server, automating a manual workflow, or scaling a SaaS product without breaking what already works — send me a message with what you're building.

🚀 Full-Stack AI Augmented Web Engineer | 6+ years | LangChain • Voice AI • OpenAI • Nest.js • AWS Hi, I'm Hammad. I build production-grade AI SaaS platforms, RAG-powered chatbots, and Voice AI agents that don't break the moment a real user touches them.
