What a Simple Autofill Extension Taught Me About Product Engineering

My parents are not a part of the tech world. They use technology only to solve everyday activities like messaging, ordering food and booking taxis. Their idea is that as an Engineer I should know how to fix everything in the house. But a recent incident made them genuinely curious about what software engineers build and truly appreciate my profession.

For about 4 months my parents were trying to book an online ticket for a pilgrim visit. This ticket is free and is in very high demand since it can be booked only one day of a month via designated website or mobile app . They were unable to tackle the huge traffic that occurs during the time of booking. After blaming themselves for not knowing how to type faster they asked for my help.

Since my brain is wired like a software developer, the first thing I did was search for an autofill extension to make the typing part easier. Fortunately someone had recently built one for this website. I quickly downloaded it and prefilled the basic information, ID proof and contact details which normally took me 5 minutes. Once the booking started, I had to wait in a virtual queue for 3 minutes. But as soon as I was let in, I booked the ticket in 5 seconds, thanks to the autofill feature. My parents’ joy knew no bounds.

This is what useful software should do, reduce friction for its users. The autofill extension reduced repeated typing, timing stress and unwanted refresh cycles. All the things a good product should do to achieve its purpose. At the end of the day it made life easier by one small step, reminding me that an application’s practical usefulness matters more than fancy features, AI hype and complex enhancements.

This experience quietly reminded me why we build products in the first place: to reduce user friction, improve the overall user experience, and ultimately solve the problem the product was designed for. It reinforced the idea that meaningful engineering need not always be building massive systems with complex architecture, most of the time it’s about reducing stress for users.
