The Problem
LinkedIn professionals waste 45+ minutes per session manually evaluating job postings, crafting generic comments, and guessing which roles match their skills. The workflow is fragmented across multiple tools and painfully slow.
The Solution
I built LinkPilot AI Pro — a privacy-first Chrome extension powered by Groq + Llama 3 that brings intelligent automation directly into LinkedIn. Smart comment generation in multiple styles, instant job-profile matching, batch scoring with color-coded badges, and AI-driven profile enhancement — all without leaving the page.

My Role & Deliverables
Key Features & Scope
Major capabilities built into this product:
Key Technical Decisions
- FastAPI on Vercel for serverless, high-performance API serving
- Manifest V3 Chrome Extension with secure service worker proxy
- Supabase for passwordless device authentication
- Structured prompt engineering for consistent AI output quality
Challenges & Engineering Solutions
Dynamic LinkedIn DOM Parsing
LinkedIn frequently updates its DOM structure. Built modular, decoupled parser components (job-card-parser, job-page-detector) that isolate DOM extraction logic for instant updates.
Chrome Web Store Security Compliance
Strict Manifest V3 rules prohibit inline scripts and arbitrary network calls in content scripts. Implemented an isolated background service worker proxy to securely sign API requests.
Sub-Second AI Response Latency
Users expect instant comments and job match scores. Leveraged Groq LPU hardware acceleration paired with Llama 3 to deliver sub-second generation directly into the browser context.
Privacy-First Data Architecture
Designed data flows to minimize sensitive user payload storage, relying on Supabase for lightweight, passwordless auth tokens while keeping user browsing data strictly ephemeral.

Vercel
FastAPI backend on Vercel serves RESTful endpoints for comment generation, job analysis, batch scoring, and profile enhancement. The Chrome Extension uses a service worker (background.js) as an API proxy while content scripts extract data directly from LinkedIn's DOM. Groq + Llama 3 powers all AI features. Supabase handles database storage and secure, passwordless authentication.
Performance & UX Highlights
Outcome & Production Status
Reduced average job application evaluation time from 45 minutes to under 10 minutes. The batch Job Scanner feature lets users score an entire page of jobs at once. Successfully rebranded to LinkPilot AI Pro and implemented strict data privacy measures, ensuring the extension is compliant for the Chrome Web Store.
