Remote-ready · I work US & UK business hours · start this week
I turn ad spend into pipeline — and build the system that scales it.
I'm Sunny Guha — a paid-media & growth strategist with 12+ years and $400K+ in monthly ad spend across 500+ brands. As a Computer Science engineer I also ship AI automation, custom CRMs and production apps end-to-end.
Currently taking 1–2 new engagements this quarter.
Let's talk — start here
Every pixel you're clicking — and the CRM behind it — I built alone.
This website, its copy, the booking flow, the AI chatbot and a full custom CRM — designed, written and shipped end-to-end with agentic AI, by one person. What you're browsing isn't a case study of the work. It is the work — and I can build the same for you and your clients.
Consider this page your live demo.
Brands I work for
Hire one person. Get a whole team.
Most companies stitch together 8 specialists — and the hand-offs, meetings and salaries between them — to do what I do end-to-end. You get all of it in one operator: one hire, one salary, zero hand-offs.
Remote, but never distant.
The usual worry with hiring remotely is time zones and communication. Here's how I remove it — the same way I've run US, UK, UAE and Australian accounts for 12 years.
- Your hours, not mine
I hold overlapping hours with US (ET/PT) and UK/EU teams — standups, reviews and launches happen live, on your clock.
- Async-first, always documented
Daily written updates, Loom walkthroughs and shared dashboards. You always know what's running and what's next — no chasing.
- Reachable in hours, not days
WhatsApp, Slack or email — I reply within a couple of hours, most days. Twelve years of distributed accounts made async second nature.
References & LinkedIn recommendations available on request — I'm happy to walk you through live client dashboards on a call.
A quick intro — who I am, how I work, and what I'd do for you.
Held in high regard by the people who actually work with me.
Not paid reviews — genuine, unsolicited recognition from the teammates, team leads, managers and directors I've worked with. Real people, real dates — captured from internal peer-recognition tools and team chats.
“I know it's not Thank You Thursday, but I wanted to give a shoutout to Sunny from the Paid Media team for taking the lead on a client escalation. He got on a call with the client, proposed a strategy, ensured action items were completed, and kept the client informed throughout the process. This is a great example of ownership and client care!”
“Special shoutout to Sunny for his outstanding knowledge and expertise in Google Ads. His ability to navigate and implement effective strategies is impressive. His attention to detail is remarkable and he tackles every task assigned to him, ensuring nothing is overlooked. Sunny consistently delivers high-quality work, making him an invaluable asset to our team.”
“Sunny is such an invaluable asset to the team. He works unbelievably hard and consistently works beyond his hours and on weekends to ensure everything runs smoothly. He is so talented and ambitious that it's contagious. Sunny thank you for all that you do, we are so lucky to have you and it is a pleasure working with you :)”
“Sunny is one of the most active team members among us; he never waits for his office hours to finish his assigned tasks.”
“Sunny is the one who is available every time for all of us. He is very helpful and works like a machine. Extremely knowledgeable and always helps the team at a very good level.”
“Unconditional support is what Sunny gives. Some call it support, Chuck Norris calls it 'a worthy ally'. Thank you, Sunny!”
“Thank you Sunny for your ongoing support and for your quick help this week when I lost access to my Google account. I appreciate you responding via WhatsApp and connecting me with the account manager to resolve the issue.”
“I always know I can count on you, no matter what time or what the situation is. Thanks brotha!”
“I appreciate all your hard work on the CallRail project. This will have a great impact on how we deliver results to our clients.”

View all recognitionsTwo skill sets that almost never live in one person.
A senior performance marketer and a Computer Science engineer — in the same operator. The strategy and the machine that runs it are one decision, not a hand-off.
For twelve years I've run performance marketing at the top end — $400K+ in monthly ad spend across 500+ brands on Google, Meta, LinkedIn and YouTube, with 22–30x ROAS in healthcare, 9–12x in e-commerce and 7x+ across industries. I think in CAC, blended ROAS and pipeline, not impressions.
I'm also a Computer Science engineer (M.Tech, CSE). I built a multi-agent AI marketing-automation platform — 20+ concurrent AI agents orchestrated as Node.js services with a custom CRM and WhatsApp/email automation — shipped 100+ algorithmic trading systems (MT5, PineScript), and build production sites and apps with agentic AI, including this one.
That combination is the whole point. I don't hand off the tracking, the landing pages or the reporting tool to someone else and hope. I build them — so the strategy and the machine that runs it are the same decision.

A few engagements where the strategy, the build and the reporting were all mine.
This site — and a full agency CRM — were built end-to-end with Claude & Codex.
Front end and backend. Marketing site, high-converting landing pages, and a working CRM — dashboard, pipeline, leads and auth — designed and shipped as a non-coder directing agentic AI.
I work the way a technical lead works: own the architecture, review every change, and ship. The result is production Next.js, not a prototype — the proof is the software you're reading this on.
- Next.js · React · TypeScript
- CRM · pipeline · auth
- Server-side tracking & APIs
- Core Web Vitals & SEO built in
The stack that lets one person build anything.
The AI models, agentic coding tools, automations and analytics I run daily — and the programming stack I ship with, all directed through agentic AI.
AI models
The models I run daily for strategy, copy, analysis and building.
Agentic coding
How I ship production software without a dev team.

Diagnose. Build. Scale. Compound.
A repeatable operating system for turning spend into an asset — not a monthly gamble.
Diagnose
Audit the account, tracking and funnel. Find where spend leaks and where demand is being left on the table — the honest baseline no dashboard shows you.
Build
Rebuild the engine — account architecture, server-side tracking, creative system and landing pages — instrumented so every dollar is attributable.
Scale
Push profitable spend with agentic AI in the loop — bidding, budgets and creative iterated continuously by a multi-agent system against a blended-ROAS target.
Compound
Layer SEO/GEO, organic social and internal software so results stop being rented from ad platforms and start becoming an asset you own.
Certified where it counts — measured on results.
No borrowed logos or inflated numbers. The proof is the certifications, the recognition and the ROAS — all verifiable, and all mine.

The questions I get before we start.
Still unsure if it's a fit? Book a call — we'll know inside twenty minutes.
Yes — I'm available for senior in-house roles and a small number of select projects. That ranges from fractional head-of-growth engagements to fixed-scope builds (a paid-media rebuild, a landing-page system, a CRM). Fastest way to find out if it's a fit is a short call.
Entirely remote, and I run overlapping hours with teams across the US, UK, UAE and Australia. Twelve years of managing distributed accounts means async-first communication and clear reporting are the default, not an afterthought.
Both work. I take senior full-time and fractional positions where I own growth end-to-end, and I take defined freelance projects with a clear outcome. If you're not sure which you need, that's usually the first thing we figure out together.
Most people are a marketer or an engineer. I'm both. I architect and run $400K+/mo in paid media across 500+ brands, and — as a Computer Science engineer — I build the tracking, landing pages, dashboards and CRM the media strategy depends on, with a multi-agent AI system giving me the leverage of a team.
This site and a complete agency website plus a working CRM — front end and backend, auth included — were built end-to-end with Claude Code. I direct agentic AI the way a technical lead directs a team: architecture, review and shipping. The proof is the software you're looking at.
