Project
Support assistant
Deflection-ready- Automated common support tickets with grounded answers.
- Routed by intent and escalated low-confidence cases.
- Improved ticket deflection while keeping a safe handoff.
Why this project is valuable
Strong applied-AI signal
A support assistant shows you can ship an LLM product with grounding, routing, and safe human handoff, not just a demo.
Good ATS coverage
The project naturally supports LLM, RAG, intent routing, support automation, and human-in-the-loop keywords.
Clear business relevance
Ticket deflection and faster resolution are concrete outcomes hiring managers value.
Good interview depth
You can discuss grounding, intent classification, confidence thresholds, escalation, and quality safeguards.
Project overview
An LLM support automation assistant is strong AI engineer resume material because it shows you can deploy an LLM product responsibly, deflecting routine tickets while safely escalating hard ones.
The assistant classifies ticket intent, retrieves grounded answers from the knowledge base, responds with citations, and escalates low-confidence or sensitive cases to human agents with context.
On a resume, that gives you concrete ways to describe RAG grounding, intent routing, confidence-based escalation, human-in-the-loop design, and how the assistant improved deflection without harming quality.
Architecture overview
Project flowIncoming ticket
Support tickets arrive from chat or the helpdesk for handling.
Intent classification
An intent classifier routes tickets to the right handling path.
Grounded retrieval
Relevant knowledge-base content is retrieved to ground responses.
Answer generation
The LLM drafts a grounded answer with citations for the user.
Confidence-based escalation
Low-confidence or sensitive cases hand off to human agents with context.
Quality monitoring
Deflection, satisfaction, and escalation rates are tracked over time.
What this project includes
- Intent classification and routing
- Grounded retrieval from the knowledge base
- Cited answer generation
- Confidence-based human handoff
- Deflection and quality monitoring
Tech stack
This stack is practical for AI engineering hiring because it shows a complete, responsible LLM product with safe escalation, not a toy chatbot.
OpenAI
Powers intent classification and grounded answer generation.
pgvector
Stores knowledge-base embeddings for retrieval.
LangChain
Orchestrates routing, retrieval, and generation steps.
FastAPI
Serves the assistant and integrates with the helpdesk.
Zendesk
Provides ticket intake and human handoff integration.
Python
Implements routing, escalation, and monitoring logic.
Features implemented
Grounded answers
Knowledge-base grounding with citations reduces hallucination in replies.
Intent routing
Classification routes tickets to the right handling path.
Confidence escalation
Low-confidence cases hand off to humans instead of guessing.
Human-in-the-loop
Safe handoff with context keeps quality and trust high.
Deflection tracking
Metrics show how many tickets were resolved automatically.
Quality safeguards
Monitoring catches poor answers and escalation gaps.
Resume bullet examples
These bullets show how to present support automation as responsible applied-AI engineering rather than 'built a chatbot.'
- Built an LLM support automation assistant with RAG grounding and citations that resolved common tickets over a knowledge base.
- Added intent classification and confidence-based escalation so low-confidence or sensitive cases handed off to human agents with context.
- Integrated with the helpdesk for safe human handoff, keeping a human-in-the-loop for hard tickets.
- Tracked deflection, satisfaction, and escalation rates to improve automation without harming support quality.

ATS keywords extracted from this project
Use keywords that reflect a responsible applied-LLM product, not only the word chatbot.
Interview questions based on this project
Support automation projects often lead to questions about grounding, escalation, and protecting quality.
How did you keep answers accurate?
I grounded responses in the knowledge base with citations and escalated low-confidence cases instead of letting the model guess.
How did you decide when to escalate?
I used confidence signals and sensitive-intent detection to hand off to humans with full context for hard or risky tickets.
How did you measure success?
I tracked ticket deflection, customer satisfaction, and escalation rates, optimizing deflection without degrading quality.
How would you improve it further?
I would add automated answer evaluation, feedback-driven retrieval improvement, and per-intent quality dashboards.
Common mistakes
Explain grounding, routing, and escalation so it sounds like responsible applied AI.
Discuss human handoff so the assistant sounds safe, not reckless.
Mention RAG grounding and citations so accuracy is credible.
Include deflection and satisfaction so impact is concrete.
FAQ
Is a support automation assistant a good AI engineer resume project?
Yes. It demonstrates a complete, responsible LLM product with grounding, routing, and human handoff that applied-AI roles value.
Do I need a real helpdesk?
A sample knowledge base and ticket set work for a portfolio, as long as grounding and escalation logic are real.
Should I mention human-in-the-loop?
Yes. Safe escalation is a strong signal that you build responsible, production-minded AI.
How many bullets should I use for this project on a resume?
Usually two to four bullets. Focus on grounding, escalation, and deflection impact.
