Dipanjan Roy — Tech Marketer

The page. The ads. The AI that closes. Built by one person.

I work as a Tech Marketer

Full-stack marketing, actually full-stack: I design the landing page, run the Meta ads, and build the WhatsApp + voice AI that answers every lead in seconds and books the call. One person, zero handoffs.

Résumé · the twenty-second version

What I've actually done, with receipts.

I count what reached the bank — not what the ad platform says it sold.

  1. 2023 — Present

    Performance Marketer

    Independent projects (part-time) · D2C campaigns: MilanYog and e-commerce products

    AI Automation & Lead Generation

    Part-time · B2B AI services for clinics, gyms, salons and local services

    • An AI voice agent that calls new leads within 15 minutes and sends an automatic WhatsApp recap; four WhatsApp templates approved by Meta.
    • Prospecting: 640 local-business leads (London, Toronto, Sydney, Dubai) via the Google Places API.

How these are counted: every order is matched to Razorpay, not Ads Manager. That is how I found the Meta Pixel double-counting, and test orders marked as paid — I count captured payments only.

Don't read about it. Run it.

Describe your business — or paste your website — and get a go-to-market plan in under a minute. It is the same framework I use on my own brands, running live.

No business handy? Try:

Written from the brief you give it. It is strategy scaffolding, not a researched market report: it has no data on your market and will not quote statistics, and anything it had to assume is listed at the end.

Growth Systems · In Production

The machinery behind the marketing.

Pretty pages don't close leads — systems do. These run live behind my own funnels: they answer, qualify, follow up and book while I sleep. All designed, coded and wired by me.

WhatsApp AI Sales Agent

Monica

Answers every WhatsApp lead in seconds, reads the buyer's stage, pushes toward a booked call via Cal.com — and hands over to a human the moment it should.

▤
Automated Lead Magnet

AI Audit Funnel

A visitor drops their website URL — the system researches the site, writes a 7–12 page branded PDF audit and delivers it on WhatsApp + email in about two minutes. No human in the loop.

☎
Voice AI

AI Receptionist

A phone call comes in over SIP; a natural AI voice answers, qualifies and triggers follow-up — so a missed call is never a missed customer.

⌖
Outbound Data

Lead Engine

Scrapers over Google Places and YouTube plus a daily scheduler that turns raw listings into scored, deduped lead lists ready for outreach.

✉
Cold Outreach

Dream Machine

Drop a prospect's URL — it scrapes their brand and drafts the cold DM plus a cinematic "your future website" teaser, personalised to them, at batch scale.

Content Studio

Cadence

A five-agent pipeline that designs carousel posts as pure HTML and renders them through headless Chrome — on-brand social content without an image model.

Architecture & Interiors

Five sites for people who build.

A development studio, two private residences, and two interior-architecture practices — the vertical I've built the deepest. Every one carries a scroll-scrubbed film of the space itself, not a slideshow of stills.

Selected Work

A one-of-one, conversion-first site for every brief.

Architecture, interiors, real estate, hospitality, retail, entertainment — different worlds, same standard: cinematic first frame, fast load, and one clear action on every page — book, reserve, enquire, buy.

About

One person who runs the whole growth loop.

Ads, landing page, WhatsApp AI, voice agent, booking — no handoffs, no agency-inside-the-agency. I design it, code it, wire the automation, run the campaigns, and watch the numbers.
