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.
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.

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 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.
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.

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.

You're standing in the work sample.
I designed, built, secured and deployed this site myself — Next.js on my own VPS, with a custom CRM behind it. So audit the thing you're already looking at: run Lighthouse on this URL and see if these hold.
Hardened, not just fast

- Mail authenticated with SPF, DKIM and DMARC; SMTP relay refused
Google Lighthouse, 2026-07-21, across all 14 public pages on the default desktop profile.

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.
