AI Recruitment Workflow Automation

I need a small-scale, cloud-hosted system that can manage my recruitment flow end to end with only minimal upkeep. Each time a vacancy opens, around eight to ten times a year, résumés arrive in a dedicated Gmail inbox. The moment they land there I want the solution to:

• detect and skip duplicate applicants
• pull the attached CV (PDF, DOCX, etc.) and parse it
• save every candidate’s core details in BOTH a lightweight database (Firestore or similar) and a Google Sheet for quick ad-hoc access

Next, an AI layer should screen each profile against a job description and shortlist on three dimensions I will supply per role: educational qualifications, relevant work experience and key skills / keywords. From that shortlisting, the system must create a simple web dashboard that at minimum shows:

• a summary list of shortlisted candidates
• their stage-by-stage progress tracking
• overall recruitment statistics so I can spot bottlenecks

Google Apps Script combined with Gemini API (or an equivalent LLM endpoint) feels like the right low-maintenance stack, but I’m open to other cloud-first ideas as long as they keep costs down and don’t require babysitting.

When you reply, please include:
1. An outline of your proposed architecture and technologies
2. Estimated development timeline with key milestones
3. A ballpark cost split by milestone if possible
4. Ongoing maintenance expectations (updates, monitoring, support)
5. Links or brief notes on any similar AI-driven hiring tools you have built

I’m aiming for something lean, reliable and easy for a non-technical team to operate once it’s live. Looking forward to your approach.
