Built an AI-powered customer support chatbot for Fontty Games from the ground up.
Designed the system prompt architecture, intent scoping, and structured JSON output pipeline using the DeepSeek API. The assistant — Sir Alfonzo Quareno IV — handles game inquiries across three titles and escalates flagged cases (refunds, bug reports, collabs, and more) by collecting user data conversationally and logging it automatically to Google Sheets via a custom Apps Script webhook🔥.
Key engineering decisions:
Structured JSON output enforced via response_format to guarantee parseable replies
Stateless service with conversation history managed per session on the frontend
Escalation logic driven entirely by model output — no hardcoded UI triggers
Prompt designed to resist persona attacks, scope creep, and language confusion
