About

I'm a brand marketer who operates at the intersection of culture, storytelling, and performance.

From launching 12 flagship smartphones at Xiaomi India to building Lumio's brand from the ground up, I've spent 7+ years shaping how consumers see, feel, and choose products. I think in narratives, operate in data, and believe the best marketing is indistinguishable from culture.

Every dimension of a launch from box design to media strategy, keynote scripting to retail execution. I've stood on stages, fronted media briefings, and managed large agency partners.

Deep Capabilities

What you're actually
hiring me for.

Not a generalist who dabbles. A practitioner who has done the work, managed the spend, and owned the outcomes across five disciplines most consultants treat as separate.

i.Brand Marketing & Strategy
+

I build brands with a point of view, not just a logo and a colour palette. From defining brand architecture to owning visual identity and tone across every touchpoint, I've done this at scale (Xiaomi) and from scratch (Lumio).

  • Brand positioning and POV development
  • Visual identity and tone-of-voice systems
  • Athlete and celebrity partnership strategy
  • 360 degree campaign architecture
  • Brand consistency across multiple channels
  • Cultural moment-making
ii.Performance Marketing
+

I don't outsource performance. I've directly owned campaigns across Meta, Google, Amazon Ads, and Flipkart Ads, building the frameworks, running the experiments, and being accountable for ROAS, ACOS, and CAC.

  • Meta Ads full funnel, creative testing
  • Google Ads search, display, YouTube
  • Amazon Ads Sponsored Products, DSP
  • Flipkart Ads PLA, display
  • ROAS / ACOS / CAC optimisation
  • Performance infrastructure setup from zero
iii.Product Marketing
+

Product marketing is the craft of making a product make sense to a consumer. I've done it for 35+ products from the earliest positioning brief to launch day, including keynote scripting, website copy, and marketplace content.

  • Product positioning and messaging frameworks
  • Box and packaging creative direction
  • Product film scripting and direction
  • Keynote and speaker notes writing
  • Marketplace A+ content and listings
  • Website copy and digital asset direction
iv.Digital Marketing
+

Digital is where brand and performance intersect. I run both. Social media strategy, content direction, influencer scouting and briefing at scale, digital media planning, and organic and paid in lockstep. 1000+ influencers activated across career.

  • Social strategy Instagram, YouTube, X
  • Influencer scouting, briefing, and activation
  • Content direction and creative strategy
  • Digital media planning and buying
  • Organic and paid content integration
  • Community building and engagement
v.GTM & Launch
+

I've launched 35+ products. I know what the week before launch looks like, what breaks, and how to hold it together. I've managed launches with 191.5K concurrent viewers. I've done surprise releases with zero leaks.

  • Go-to-market strategy and planning
  • Multi-channel launch orchestration
  • PR TML and media strategy
  • Retail and e-commerce execution
  • Live launch event management
  • Post-launch sustenance planning
