Anxiety. It’s a swarm of thousands of tiny, bright yellow, buzzing insects. On the best of days it’s just kind of … there. Just at the edge of your vision, a low hum, threatening to attack, to cover the world around you with the yellow.

On the worst of days, it’s on your skin, vibrating. It covers every inch of your body, feeding on your discomfort, the oil and sweat and grime on your body. It clouds your vision completely. It’s in your ears, making it difficult to hear the sounds of the world around you. It doesn’t sting, doesn’t bite, but it’s a sensation that overwhelms all other sensations.

Motivation

Most of abof's traffic is mobile (true for most e-commerce companies in India)
Old website took ~20s to load on 3G, which killed conversion rates
We got it down to <5s, increasing conversion rates by 40%

Part 1: Building abof.com

Choosing a tech stack
The competition: React, Angular, Angular 2, Riot, Vue
