You will get expert n8n workflow automation and AI integration system
Project details
Are basic automations no longer enough? Step into the future of autonomous workflows with advanced AI agents.
As a Full-Stack Engineer, I don’t just connect apps—I build intelligent, self-executing systems. I specialize in engineering enterprise-grade AI architectures using n8n, LangChain, and sim.ai to completely transform how your business operates, communicates, and scales.
Unlike standard no-code freelancers, I write custom code to push these platforms to their absolute limits.
What I deliver for your business:
🧠 LangChain AI Agents: Custom LLM architectures featuring conversational memory, document retrieval (RAG), and custom tool-calling to execute complex, multi-step reasoning.
⚡ n8n Orchestration: Scalable, high-performance workflows that replace expensive Zapier setups, seamlessly connecting your entire tech stack via custom REST APIs and webhooks.
🤖 sim.ai Integration: Deploying highly advanced conversational AI agents for automated customer support, lead qualification & intelligent business operations.
Your workflows should think, adapt, and execute like a human team member. Let’s build a powerful AI-driven infrastructure. Message me today to discuss your architecture!

If you're manually handling leads, follow-ups, customer support, appointment booking, document processing, CRM updates, or moving information between different tools, I can help turn that into a reliable AI-powered workflow.
My approach is simple: understand the process first, find where automation can actually help, and then build a system around the business not the other way around.
AI Agents & Agentic Automation
I build AI agents that can understand information, make decisions, use tools, retrieve data, and take actions.
Lead qualification & research agents
AI sales and follow-up agents
Customer support agents
AI email agents
Multi-agent workflows
AI assistants with tool calling and memory
Human-in-the-loop workflows
Agents connected to CRMs, APIs and databases
For more advanced workflows, I use LangGraph and LangChain to structure the agent logic and control how different steps, tools, and agents work together.
n8n & make & Zapier AI Automation
I use n8n + AI + APIs to connect your existing tools and automate complete business workflows.
CRM & lead automation
Lead capture and enrichment
Email & follow-up systems
API & webhook integrations
Google Sheets / Gmail / Slack / Notion automation
Data processing & reporting
AI business workflows
Automated notifications and approvals
Human-in-the-loop workflows
A typical workflow could look like:
New Lead
AI Research
Qualification
Lead Score
CRM
Personalized Outreach
Follow-up
Human Escalation
I can build a workflow from scratch, connect it to your existing applications, or improve an automation that is already running but needs better logic, reliability, or integrations.
RAG & AI Knowledge Assistants
I build AI systems that can work with your own business information instead of relying only on general model knowledge.
PDF & document Q&A
Company knowledge bases
Internal AI assistants
Customer support knowledge systems
Product documentation assistants
SOP and process assistants
Document extraction & processing
Vector search & retrieval
Grounded responses
A typical system can include:
Document Ingestion
Chunking
Embeddings
Vector Database
Retrieval
LLM
Grounded Response
Depending on the project, I can work with Qdrant, Pinecone, PostgreSQL, pgvector, and other data stores.
AI Voice Agents
I build AI voice systems that can interact with customers and connect conversations to your existing business workflows.
→ AI receptionists
→ Lead qualification calls
→ Appointment booking
→ Customer support calls
→ Outbound calling
→ Call summaries
→ CRM updates
→ Automated post-call workflows
For example:
Incoming Call
Voice AI
Understand Intent
Qualify Customer
Check Calendar
Book Appointment
Update CRM
Send Confirmation
I can integrate Retell AI or Vapi with n8n, CRMs, calendars, databases, and APIs so the voice agent becomes part of your complete workflow rather than operating separately.
API, CRM & Business Integrations
A lot of automation projects aren't just about the AI model. The real value comes from connecting the AI to the systems your business already depends on.
I can work with:
REST APIs
Webhooks
JSON
Databases
CRMs
SaaS APIs
OAuth integrations
& connect systems such as:
HubSpot
• GoHighLevel
• Google Workspace
• Gmail
• Slack
• Notion
• Calendars
• Google Sheets
• Custom APIs
It can retrieve information, update records, create tasks, send emails, trigger workflows, schedule appointments, generate reports, and notify a team member when human intervention is required.
Examples of Systems I Can Build
Some practical systems I can help with include:
AI Lead Qualification System
AI Sales Assistant
AI Customer Support System
AI Document Processing System
AI Receptionist
Internal Knowledge Assistant
How I Work
I don't believe every problem needs a complicated AI system.
Before building anything, I want to understand:
What is currently being done manually?
Which tools are involved?
Where does the data come from?
What should AI handle?
What should remain under human control?
What happens when something goes wrong?
What should happen after the workflow finishes?
Sometimes the best solution is a simple n8n workflow.
Sometimes it requires a RAG system or AI agent.
For more complex applications, a combination of LangGraph + Python + n8n + APIs + RAG may make sense.
