Paid media specialist first. AI-assisted builder right beside it.

I work as a Sr. Performance Marketing Analyst across Google Ads, Meta Ads, lead generation, CRO and tracking, then use agentic AI to build the software around the funnel: SaaS apps, dashboards, CRMs, backend/API workflows, QA pipelines, RAG/chatbots and automations.

No agency · no dev team · no template

Every pixel you're clicking — and the CRM behind it — I built alone.

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.

The unfair advantage

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.

How I work with your team

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 being built, tested and improved — 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.

Client care
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!

What makes me different

Two 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.

Peak healthcare ROAS
M.Tech
Computer Science & Eng.
20+ concurrent AI agents give one person the leverage of a team.

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.

  • Landing pages designed and shipped in-house

How I work

Diagnose. Build. Scale. Compound.

A repeatable operating system for turning spend into an asset — not a monthly gamble.

01

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.

02

Build

Rebuild the engine — account architecture, server-side tracking, creative system and landing pages — instrumented so every dollar is attributable.

03

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.

04

Compound

Layer SEO/GEO, organic social and internal software so results stop being rented from ad platforms and start becoming an asset you own.

Credentials

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.

FAQ

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 either a marketer, a developer or a tester. I combine growth experience with AI-assisted software delivery: requirements, architecture, build direction, QA, tracking, dashboards, CRMs, RAG/chatbots and automation workflows in one operator.

It means I use agentic AI as the build engine while I own the requirement, architecture, testing, review and shipping loop. This site, a complete agency website and a working CRM — front end, backend, auth, dashboard and pipeline — were built that way. I do not sell myself as a traditional hand-coder; I sell the modern result: faster software shipped with AI, domain expertise and QA discipline.

Hire the marketer who can also ship the system.

Senior roles and a small number of select projects — currently open. Remote, working your business hours across the US, UK and worldwide.
