About

I didn't start in marketing. I started by building things.

My first company was Sigma Academic Care — an education business I co-founded at 20 that grew to $10K MRR and 500+ students. My second was Pista, a cloud pizza delivery startup that captured 2.17% market share in Dhaka in just 5 months through digital-only marketing. Both taught me the same lesson: growth isn't about campaigns — it's about systems.

That builder instinct led me to professional marketing, first as a consultant driving 4x ROAS for an ecommerce brand (TukiTaki) and 6-cent chat leads for a sustainable products company (Nirbaan), then to enterprise scale at ADA Global (Axiata Digital) — a $550M, SoftBank-backed agency where I managed up to $16M in annual media spend across 6 countries and built a 21-person team from scratch. I earned 4 industry awards including Best Ad Ops in Southeast Asia (DRUM) and a Gold at Bangladesh Brand Forum. I was invited to judge those same awards twice.

Then I made a deliberate choice. I left the agency world to build a growth function from zero at Shikho — Bangladesh's leading edtech startup (Forbes Asia 100 to Watch). With 4 people and a $420K annual budget, I built the measurement infrastructure, experimentation culture, and lifecycle marketing engine that tripled install-to-conversion rates, improved ad efficiency by 53%, and scaled the subscriber base to 55K+ active paid users. I ran incrementality studies no one in this market had attempted. I built a media mix model without a data science team. I launched into India.

Now I'm looking for the next challenge — a company where enterprise methodology, startup builder mentality, and emerging market innovation combine to create outsized impact.
