Eliminating Gaps in Revenue Strategy for 7-Figure Brands Wanting to Become 8-Figure Brands | Sales and GTM Operations Leader | Selling is Serving

I have 10 years of experience helping early-stage startups unlock revenue by building the GTM systems they should have started with.

As a strategic operator, I work across sales, customer success, and product feedback loops to drive meaningful results. I’ve helped grow both internal teams and client companies to $5M+ in annual revenue by tightening execution, sharpening messaging, and aligning GTM strategy with real customer needs.

I’ve been an entrepreneur my entire career. Along the way, I’ve learned that doing what you can now is the only way to earn the freedom to do what you love later. That mindset also shapes how I approach AI. It's already reshaping and disrupting the world I work and thrive in. I have a responsibility to my family to prepare for what’s coming, not just react to it.

I share on LinkedIn and invite anyone to join the conversation. If you identify with anything below:
✓ building in public 
✓ startups, investing, and legacy building
✓ coffee and photography (for the creatives 😉 ) 

Connect or say hi. 

Much love, 
Aaron

Experiencing "Teaching"  !

I didn't know before that "teaching" can be so much fun, There was a time when I used to learn from my teachers and now my students are teaching me more about the world, about the behaviors, human psychology. Students are the true motivation and inspiration only if you want to learn from them. It is challenging at the same time as this generation is living in digital age, they are much faster !

Femina Magazine

A magazine which focused entirely on women issues. To be very honest this is not my forte at all. As usually these types of magazine cover fashion, gossips, entertainment, horoscopes etc. I don't believe in this type of content only as women have much more to do. So truly, didn't enjoy much but again it helped in practical learning.

Assistant Editor

Dastak Magazine

Dastak is a magazine focused on political and social issues, with the relevant target audience. 
I learn to work under pressure to meet the deadlines and to work with lack of resources. I managed the entire magazine on my own from theme selection, article writing to proofing and finalizing the magazine. Basically what I learn is, "How to WRITE" and I am glad for that.

I always thought I am an extrovert, lockdown in the pandemic taught me, I can somehow qualify for introversion too. So count me an ambivert. 

I am an educationist and storyteller. I love history to the core, and enjoy traveling unconditionally. 

Traveling gives you the ultimate perspective of life, culture, people, food and places. 

World is transforming to skill-based education, though I am a PhD candidate but I agree with the approach of skill based learning. 

I am a Lecturer in Media Studies department at Sindh Madressatul Islam University since 2012 (currently on study leave), because I am pursuing PhD in Business and Behavioral Sciences in Italy.
