We have closed submissions for Fragments Conf, Bangalore edition which will be held on 30 March. If you wish to submit a proposal for the conference, make a submission here.
Fragments is a conference on mobile engineering, including:
- State of platforms/OS
- Engineering approaches and paradigms
In 2019, Fragments is a traveling conference with editions in Ahmedabad, Bangalore, and potentially Hyderabad and Kochi (in the second half of 2019).
Topics for submission:
We seek proposals – for short and long talks, Birds of Feather (BOF) session topics, and workshops + tutorials – on the following topics:
- Deep dive technical talks on Flutter.
- AR Core: practical approaches and the business use cases.
- Reducing app size to below 10MB and how to cater for lower-end phones.
- PWA caching strategies.
- ML Kit (ML Kit | Google Developers).
- On device ML.
- Server-side ML.
- Progressive ML, where the fallback is on-device ML when the device goes offline.
- Functional programming for mobile.
- Coroutines in Kotlin.
- Mobile specific user research.
- Case studies from teams which have switched away from cross platform approaches.
- Use cases for which Native apps work versus use cases where it doesn’t make sense to build Native apps.
- Deep dive talks on performance.
- Optimising for lower-end hardware.
- Future of chatbots for conversations on mobile.
- Automating design to code.

Customer Driven Development : What, Why & How?
Think of this talk as a crash course for Mobile Developers to become Product Owners.
It will teach developers how to efficiently write & setup experiments (A/B Tests) and hence showcase a way to create apps that keep the customers at the centre of everything.
If you attend this talk you will learn how to frame the hypothesis, calculate runtime of an experiment, set up metrics to measure success so that you can act as a product owner yourself in future!
Having run over a 100 experiments in the last 2 years at Booking.com (World’s biggest OTA running massive number of A/B Tests at scale) with an enormously high success rate, I’ll present some hard to believe facts related to user experience and design that developers often overlook while shipping features.
How often do you change the colour of a button on your app? How often do you change the layout of a part of the app? How do you measure the effect of these changes? Of course you do that with a hypothesis in mind related to some business goal you want to achieve. Do you actually always validate your hypothesis?
This talk will tell you how you can convert users into customers and customers into decision makers of your product vision.
By validating all your decisions in your product through data you can be sure what’s working and what’s not. Digging a little deeper you’ll also always find a cause about why it’s working and why it’s not. Taking a step further you can easily derive what is smallest next step you can take to ship a new feature/change in your product that might positively impact your customers.
