You will get an n8n AI automation workflow powered by GPT or Claude
Project details
I build production-grade AI automations in n8n — not fragile demos that break the week after delivery.
I'm a senior engineer (Top Rated Plus, 100% Job Success) who ships AI systems used by paying customers daily: multi-tenant SaaS platforms, healthcare, and sales tech. I bring that same production discipline to your automation: proper error handling, retry logic, idempotent webhooks with signature verification, and clear documentation — so your workflow keeps running when an API hiccups instead of silently failing.
What I typically build:
• AI lead qualification and enrichment
• Call/meeting summarization pushed into your CRM
• Document processing with LLM extraction (invoices, forms, reports)
• AI email drafting and follow-up sequences
• Content generation pipelines with structured outputs
Every delivery includes source workflow, handover documentation, and a walkthrough video showing exactly how it works and how to adjust it yourself.
Not sure if your idea fits a tier? Message me before ordering — I respond within hours and I'll tell you honestly what it needs, including if an automation is the wrong tool for the job.

Affirmation ai Phase 2 Revamp
Absolutely, incorporating these points will really highlight Umar’s exceptional contributions. Here’s a revised review:
---
I am thrilled to share my experience with Umar, a stellar developer who played a critical role in evolving our project, Affirmation AI. Unlike my initial experiences with other developers, who often made the process challenging and claimed many tasks were impossible, Umar's approach was a breath of fresh air. He was always available, despite being in a completely different timezone, and his communication was impeccable.
Umar consistently delivered new builds and updates, each one reflecting a keen understanding of our needs and a dedication to pushing the project forward. His problem-solving skills were particularly remarkable; faced with issues that stumped others, Umar would acknowledge the difficulty and then pivot to finding a solution, never settling for a dead end.
His ability to listen to details and translate them into technical solutions was unmatched. Umar's work ethic and ability to manage both front-end and back-end development seamlessly integrated sophisticated designs and functionalities, making a significant difference to the usability and aesthetics of our platform.
For anyone in need of an expert in full-stack development, I cannot recommend Umar enough. His proactive approach, technical prowess, and unwavering dedication have been instrumental in the success of our project. We are so impressed with his performance that we've already started a new contract with him to continue our collaboration. If you're looking for someone who truly goes above and beyond, Umar is the person you want on your team.

Job Success
Rawalpindi, Pakistan - 2:24 pm local time
What I build:
⚙️ AI-Powered SaaS Platforms — End-to-end development from architecture to deployment. I've built systems integrating OpenAI, Anthropic Claude, AssemblyAI, Recall.ai, and Fathom with Node.js/Express backends, React frontends, MongoDB, Redis, and BullMQ job queues. Real multi-tenancy, role-based access, Stripe billing, and CI/CD pipelines — not toy apps.
🤖 LLM Integration & Custom AI Workflows — RAG pipelines, multi-agent systems, prompt engineering, custom AI model integration. I connect LLMs to your existing systems with proper error handling, retry logic, and production reliability.
🔊 Speech & Vision AI — STT (AssemblyAI, Whisper), TTS, OCR, image analysis, PII redaction with configurable policies, and speaker diarization. I've implemented async transcription pipelines processing thousands of calls with production-grade reliability.
🔗 AI Workflow Automation — n8n, custom webhook integrations, BullMQ queue-based processing, GoHighLevel, Stripe webhooks with idempotency and signature verification. I replace fragile "fire-and-forget" patterns with reliable, queue-backed architectures.
🛠️ Full Stack Engineering — React, Node.js/Express, MongoDB Atlas, Redis, PM2, Hetzner/AWS, GitHub Actions CI/CD. Security-first approach: rate limiting, input validation, cross-tenant isolation, audit logging.
What sets me apart:
→ I've shipped a production AI SaaS platform with real users and real payments — not just tutorials and side projects
→ 100% Job Success Score across 23 completed contracts
→ Security-first mindset: I've found and fixed privilege escalation bugs, cross-tenant data leaks, and authentication bypasses in production systems
→ I write tests. Every feature ships with unit + integration test coverage
→ Top Rated Plus on Upwork with 5-star rating
Recent production work includes:
Webhook reliability overhaul replacing fire-and-forget with BullMQ queue processing + Stripe recovery cron
6-vulnerability security audit (privilege escalation, broken access control, cross-tenant scope issues)
N+1 query optimization reducing database calls from 316 → 7
OAuth integration with Fathom AI for automated meeting imports
PII redaction engine with mandatory + configurable policies (96 tests passing)
Real-time AI sales coaching via Recall.ai bot integration with live WebSocket streaming

Steps for completing your project
After purchasing the project, send requirements so Umar can start the project.
Delivery time starts when Umar receives requirements from you.
Umar works on your project following the steps below.
Revisions may occur after the delivery date.
Discovery & scope confirmation
I review your answers, map the trigger-to-outcome flow, and confirm exact scope, apps, and the AI step's job before writing anything — so there are zero surprises later.
Workflow design & AI prompt setup
I design the n8n workflow structure and engineer the AI prompt (GPT/Claude) with structured outputs, so responses are consistent and machine-usable — not random text.
