  • Abstract:
  • Career indecision among final-year engineering students is a pervasive problem that generic counselling sessions fail to address adequately. This paper presents CareerPath AI, a full-stack web application that recommends technology career paths from two complementary sources: (1) a proportion-based skill-matching engine querying a curated Firebase Firestore career database, and (2) a large language model (LLM) fallback using OpenAI GPT-3.5-turbo for goal-oriented or low-coverage inputs. The system employs a cascade hybrid architecture in which the database layer is always queried first; the LLM layer is triggered only when results are insufficient or when the user supplies free-text career goals rather than discrete skills. Testing across fifteen structured scenarios demonstrated sub-400 ms median response times for database queries and sub-3 s for LLM-assisted queries, with correct results in all fifteen cases. The paper documents the design, scoring algorithm, prompt engineering strategy, merge-and-deduplication logic, and lessons learned, and situates the work within the broader recommender systems and educational technology literature.
