Ready for work
Shantanu is ready for their next project!
AI lead generation and cold email automation that finds prospects, audits their website and writes a personalised pitch, built end to end with Gemini AI and Google Apps Script.
How it works:
→ AI prospecting: finds businesses in 6 niches across 5 countries (India, USA, UK, Australia, UAE)
→ Website audit: checks GA4, Meta Pixel, Google Tag Manager, Google Ads tag and real mobile speed (PageSpeed API)
→ Gemini AI writes a personalised email built on the biggest problem it verified on that site
→ Every email includes a visual audit: scorecard, speed chart, business impact and a clear next step
→ Human approval in Google Sheets before anything is sent
→ Gmail sends in the prospect's local working hours (max 20/day), follows up after 4 days in the same thread, detects replies and bounces, and emails me a daily summary
Built to be honest and safe: it never pitches a problem it couldn't verify, includes an opt-out and a do-not-contact list, and runs 4 automations at 0% error rate.
Stack: Gemini API · Google Apps Script · PageSpeed Insights API · Gmail API · Google Sheets

Built an Instagram auto-publisher that posts a Reel every day at 7 PM with zero manual work.
How it works:
→ Drop a video into a Google Drive folder
→ Gemini AI writes the caption: hook, 5 hashtags and a call to action
→ The Reel joins a Google Sheets queue with its exact go-live date
→ At 7 PM the Instagram Graph API publishes it automatically
Built to run unattended: chunked uploads for videos up to 300 MB, it waits for Instagram's processing, retries on errors, refreshes its access token weekly, and emails me if anything fails or the queue runs low.
Result: consistent daily posting, and the only job left is recording videos.

Revenue Leak Radar: AI Analyst That Caught Broken Tracking on Day 1
📸 Real build, real screenshots, not mock-ups.
I built an AI analyst that checks a store's GA4 data every morning, spots revenue drops, funnel leaks and broken tracking, and explains each issue in plain English with a cost, an action and an owner.
The result: when revenue showed $0 but 19 customers had actually paid, the radar flagged it as a tracking problem on the first day, not a sales crash.
What it does:
• GA4 → BigQuery: 10 business metrics every day
• Compares each day to the same weekday over 28 days
• Catches orders recorded without revenue
• Gemini writes the diagnosis, action and owner
• Sends a visual report and an alert email
• "Ask your data" box: type a question, it writes and runs the SQL
Tools: Google Apps Script, BigQuery, GA4, Gemini API, Google Sheets
Cost: $0 (free tiers only)
Tested on Google's public GA4 demo dataset (Google Merchandise Store).
