Project details

I connect your tools (CRM, Google Sheets, email, databases, APIs) into one automated workflow in n8n or Make, and add LangChain/LLM agents for the steps that need real intelligence: classifying, summarizing, enriching, routing, and replying.

What you get:
 • A mapped workflow (triggers → logic → actions) you approve BEFORE I build
 • AI agents with tool-calling, branching logic, and human-in-the-loop where it matters
 • Error handling, retries, and logging so it fails safely — not silently
 • Full documentation + a walkthrough video so your team owns it

I'm a senior engineer with 7+ years in production systems (fintech, edtech, healthtech). I write real production code AND understand LLM orchestration, most freelancers do only one, and that's exactly where automations break.

Message me 2–3 sentences about the process eating your time, and I'll tell you precisely how to automate it.

Full Stack Developer Needed - AI SaaS Hashir is an excellent full stack developer. He jumped straight into our AI SaaS platform and shipped new features across Next.js and Node.js, and handled our OpenAI and Claude API integrations cleanly. He also went beyond the scope, while working, he audited our auth flows and caught a critical issue in our Supabase Row Level Security that we missed entirely, then walked us through exactly how to fix it. Communication was fast and clear, the code was well-documented and easy to hand off, and he delivered exactly what we scoped. And beyond full-stack work, he's genuinely strong at AI automation too. Highly recommended!

Process to use IA to convert files math and latex to HTML Hashir helped me develop a system that makes effective use of AI through well-thought-out recommendations. He consistently delivers high-quality work, carrying out thorough research beforehand to ensure that nothing is overlooked and that solutions are successfully implemented all the way through to the final result.

Full Stack Developer (7+ yrs) specialized in AI automation and production SaaS. I help SaaS founders and ops teams replace slow, manual workflows with AI agents and full-stack software that runs at scale and that your team actually owns, not a demo you outgrow in a month.

The gap I fill: most "AI developers" stop at an API call, and most automation freelancers can't ship production code. I do both, which is what real AI automation takes.

Across 20+ products in fintech, edtech, and healthtech (HIPAA, PCI-DSS), I've led engineering teams and shipped systems that hold up under real traffic. Top Rated on Upwork.

On a recent AI-SaaS build, I caught a critical Supabase Row-Level-Security hole the team had missed, outside my scope, and showed them the fix. That instinct to audit, not just code, is what you're hiring.

WHAT I BUILD
- AI Automation & Agents, LangChain / LangGraph multi-agent and tool-calling workflows, RAG pipelines (pgvector, Pinecone), and n8n / Make orchestration with branching, error handling, and human-in-the-loop. Plus custom MCP servers so AI works securely with your tools and data.
- Full-Stack SaaS: Multi-tenant Next.js / NestJS / Node.js / Python products with Stripe billing, auth, admin dashboards, and analytics. Built end to end.
- AI-Powered Ops: CRM and workflow automation (HubSpot, Salesforce, GoHighLevel) for lead enrichment, follow-ups, and pipeline automation.

CORE STACK
Next.js · React · TypeScript · Tailwind · Node.js · NestJS · Python · FastAPI · PostgreSQL · Supabase · MongoDB · AWS · Docker · OpenAI · Claude · LangChain · LangGraph · RAG · MCP · n8n · Stripe

RESULTS CLIENTS GET
- Re-architected a US bank's auth layer to OAuth 2.0 / PKCE
- Built a multi-tenant RAG system (hybrid BM25 + dense retrieval) on real data
- Cut cloud spend 35% and lifted concurrent users 50%
- Shipped 40% faster with CI/CD and Infrastructure-as-Code

HOW I WORK
I scope before I build: free 20-min discovery call → architecture doc → phased build with milestones → handoff with full documentation. After that, proactive updates, clean modular code, and support that doesn't vanish at launch.

You get one person who's both an AI-automation architect and a senior Full Stack Developer production code, LLM orchestration that holds together, and documentation thorough enough that your team is never stuck depending on me.

Send me two or three sentences about the workflow or product costing you the most time. I usually reply within a few hours, and most projects start within 48.

Steps for completing your project

After purchasing the project, send requirements so Hashir can start the project.

Delivery time starts when Hashir receives requirements from you.

Hashir works on your project following the steps below.

Revisions may occur after the delivery date.

Discovery & Workflow Mapping

Kickoff to understand the process. I deliver a visual workflow map (triggers → logic → AI steps → actions) and confirm tools, data, and success metrics before building.

Connections & Access Setup

I set up the automation platform (n8n or Make) and securely connect your apps, APIs, and data sources using your own accounts and least-privilege access.

Review the work, release payment, and leave feedback to Hashir.
