My Story

From curiosity to campaign mastery.

As a performance marketing specialist in India, I help brands scale with data-driven ads. My journey into digital marketing started with a curiosity about how data-driven advertising directly influences business outcomes. That curiosity evolved into deep expertise in paid search across Google, Bing, Meta, LinkedIn, Amazon, and Yahoo Japan — and I’ve been obsessed with optimising every last metric ever since.

Over 4.5 years I’ve built and scaled campaigns for D2C startups and Fortune 500 companies alike, across EMEA, APAC, and NAM. At Assembly Global I manage a $6M quarterly SEM budget. At Qlikmatrix before that, I ran full-funnel global campaigns — Search, Shopping, Display, Video, and Performance Max — owning end-to-end strategy and execution.

"I don't just run ads. I build systems that compound — where every campaign teaches the next one how to win."

I’ve improved CVR by 55% for multiple brands through rigorous A/B testing, and achieved a 5.5× ROAS improvement through strategic budget allocation and smart bidding. I leverage SA360 to streamline cross-platform workflows and mentor SEM teams — because great performance starts with great process.

Core Values

How I work, and why it makes the difference

These aren’t buzzwords — they’re how I operate on every single engagement, every single day.

Results Over Vanity

Clicks and impressions are starting points — not success metrics. I obsess over revenue, leads, and profitability. Every decision traces back to the bottom line with clear KPI tracking: CTR, CVR, CPA, and ROAS.

Always Testing

Good enough is the enemy of great. I run structured A/B experiments on ad copy, bidding strategies, audience targeting, and landing pages — because the next 15% gain is always hiding somewhere.

Radical Transparency

You'll always know exactly what I'm doing and why. No hiding behind confusing dashboards — clear reporting in plain language, client QBRs with genuine strategic insight, zero fluff.

Scalability by Design

Every campaign I build is architected to scale. I leverage SA360 to streamline cross-platform workflows and reduce manual dependency so that when we grow budget, performance doesn't fall apart.
