How I increased Conversion with new UX & PWA for RailRestro [Case Study]

How I increased Conversion with new UX & PWA for RailRestro [Case Study]


Every one likes increased conversion and decreased bounce rate for their eCommerce web and mobile app. So does our client RailRestro wanted with us. The first version of Railrestro web app was built on Cakephp Framework back in 2015 by our team in which most of the development, design , ux all was done single handedly by me. 

The Client

RailRestro is official e-catering partner of Indian Railways IRCTC which delivers restaurant food in train as agregator across India. At first we had just the front-end web app from where people used to place order from partner restaurants, Later after 3 years of operation and lacs of food orders processed we were requested to build an app, We chose to build a hybrid mobile app for IOS and Android. But with the growth in order volume while crossing 10 lac orders we needed to improve ux of web app and mobile app as the user base of mobile exploded to over 95%. 


We needed a full rebuild of Web app and Mobile app both as mobile app was almost fulfilling the purpose but was lacking features and slow development cycle for the mobile app development was keeping us from deploying rapid changes and also the UX on Mobile web / Desktop and Android app was totally different. 

New Objective

After discussion with the founder and their team we came up to develop single PWA app so that we can focus on the mobile first ux and rapid improvement was possible keeping speed and seamless design on all platform I was handed over task to re design the whole web app and replace the android app with the new PWA web app which was to be served also via play store. 


NEW UX on Desktop & MOBILE APP Screen

Challenges and our Approach

Because the web application front-end was in production and had to plan the new app development and transition without disturbing most of the url structure due to SEO rankings it was tough listing and planning every page and develop totally fresh on a new stack, I used Laravel with bootstrap 4 to design and code the backend and frontend for new PWA app of Railrestro. I had to be careful as conversion pages url, landing pages which were indexed and events to be migrated in new app to reflect the similar analytics data specially for goal conversion. 

The New Ordering UX Screen Checkout Page and Confirmation

The Result

After initial testing and feedback gathering we launched the new app and measured the performance of application load time impact on conversion rate, total eCommerce transaction, bounce rate and other metrics and found significant improvement in all areas.

Performance Improvement was in multiple x to the previous app.

GT METRIX Report compared with peer
Lighthouse SCORE for PWA (The Best we achieved)

When we compared whole week analytics data since we launched new app the bounce rate decreased by 4 percent , Conversion Rate Increased from 5 % to 8% Sessions increased by approx 25 % on an average. Cart abandonment rate decreased by 2x.


The period of 4 months was challenging due to the fact that we had to migrate every feature, content and improve the ux at the same time, but the hundreds of pulls and pushes along with feedback from client end had made it possible and we are happy with the significant improvement in website performance, goal completions & conversion rate.

We encourage you to test the new RailRestro app and experience ordering food in train it your self.

How to Install Linux Bash on Windows 10 & run Ubuntu inside it

How to Install Linux Bash on Windows 10 & run Ubuntu inside it

First Personal computer I bought was preloaded with Windows 98 than came windows Xp which I loved most and from the next new release I started hating it. And between the period of Windows Vista and Windows 7 I had totally switched to a linux flavour desktop Ubuntu as my Primary Computer. However 2 years ago I bought Macbook Air and realised how much it was easy for me as a full stack web developer and server admin to code and manage the servers with both Linux and Ubuntu while running open-source web server stacks.

But Very recently I bought a Windows 10 desktop PC for home use after the windows has matured and is now way better than it was few years back. I came to know that Windows 10 has now stable Linux Bash and support for Ubuntu and linux system builtin after (Fall Creators Update). In this Tutorial I would lay down steps to enable “Windows Subsystem for Linux Bash”   feature that will allow you to natively install Ubuntu and use it within Windows session without any virtual box setup. I had tweeted after I came to read about the news in Microsoft Update blog. Here is the easy steps you can take to enable this and use Ubuntu yourself in your Windows 10 Pc.

Enabling Windows Subsystem for Linux feature in Windows 10

Before I start This feature will not work in windows 32 bit version Choose Windows 64 bit for this you should be any way switching to 64 bit version of Windows.

So if you are using Windows 10 64 bit Go to Control Panel > Programs > Turn Windows Features On or Off than enable “Windows Subsystem for Linux” in dialog box click ok and let the process finish.

Enabling Windows Subsytem for Linux

As your computer restarts you can than choose to install Ubuntu on your Windows 10 from Microsoft Store you will see list of many Linux distribution when you search “Linux” in Windows 10 Store. I recommend using Ubuntu as it works very well for all my purposes like connecting to remote servers using ssh and taking backups using rsync command.

After you have installed Ubuntu or any other linux distribution from the store you can start it from the Start Menu as in following picture as I had installed Ubuntu.

You might want to pin this application shortcut to your Start menu, desktop or in taskbar for quick access.

First time you open the Ubuntu app from start menu you would be prompted to create a password remember you would be automatically given a username which will be same as your windows username. Just set your password and you are in to the world of Linux.

That’s It if you are user of Mac Os or Ubuntu already you must be familiar from here happy using linux on your windows.

The information is key for passengers traveling via train to keep their travel comfortable and cut the several issues they have to face, RailMitra is the answer to multiple issues train travellers come across in smarter way using cross platform App with PWA capabilities which lets it work seamlessly across devices and platforms.

What RailMitra app does for train Travellers?

RailMitra as the name is a friend for every train traveler currently you can get information about your PNR status, Predictions or chance of Wait-list ticket confirmation, Train Running Information, Train Schedule, Fare information etc. which uses Artificial Intelligence and machine learning practices in background. Later team of RailMitra have roadmap to offer multiple services to train travellers such as Order Food in Train, Book Train Tickets, Book Bust Ticket and more.

How RailMitra App is implementing AI & ML practices?

“Nitish Kumar” the founder of RailMitra is focused on implementing Artificial Intelligence , Machine learning practices in RailMitra Mobile and Web application.  As a lead product developer for RailMitra I have been heading a team of developers to implement various AI and ML techniques to make app more useful for users and provide information they need.

Apart from improving user experience we are gathering historical data of all  trains running instances to provide you recommendations for booking train ticket, food or plan your travel based on train delays predictions and more. These features would roll with time as we gather more data.

As we are dealing with huge data-set and processing information we would frequently release train running performance reports users feedback about stations and more.

Consequently, as RailMitra expands and progresses I would share more information on it.  Working with such app while learning and implementing AI is a highly exciting for me.

How SevaMart offers you On Demand Home Services in Patna?

How SevaMart offers you On Demand Home Services in Patna?

There were days when we had to suffer finding technicians such as Electrician, Ac Repair technician , Fridge repair , Water purifier repair technicians in Patna. And all the contacts referred by friends didn’t came to use all the time as many technicians were unprofessional who either didn’t ever came within their promised time or they charged fortune for a very simple repair. Even many of technicians charged a kind of Visit/inspection fee in case we rejected there offer for repair or their service because it was too costly. However these are common issue specially for those people moving to Patna from other parts of Bihar or out of Bihar. As a common man I also had faced such issues multiple time at my business place and at home.

On Demand Repair Service in Patna
SevaMart recently launched Mobile App for easy booking of Home Services.

Then just by coincidence on a day a company called Seva Mart consulted us claiming they had solution to eliminate these pains for people of Patna at least they told us so. And we were asked to build web application frontend solution for their consumer , mobile app for technicians and backend app to mange whole process of providing on-demand services to their consumer. As many of you already know I am lead programmer at Webx99 which offers full-stack app development services to business in Patna we agreed and built a robust solution for them. A frontend website, mobile app for user , another mobile app for Technician to process bookings/jobs and a backend for office use.

Now people of Patna can book technicians using website or via phone call. Recently they have launched their SevaMart mobile App on android playstore that you can download right now. I have used the app to book ac repair technician for my office on few occasions. It was quite simple I downloaded the app placed booking with my preferred date time for visit, Got confirmation on my phone for technician visit and guess what I paid via online method as I prefer it over cash. They visited our office in promised time-slot and did the repair work.

Believe me the team of SevaMart is highly focused and motivated towards providing quick, low cost repair services and is gaining few hundreds new users every month.

If you are looking for an app that can let you book professional repair services in multiple categories in Patna such as AC repair and Installation , Fridge Repair, Washing Machine repair, Geyser Repair, Water purifier repair and other services you should look no where and try their service once. They are not charging any visiting/ inspection fee also all repairs from SevaMart are covered by their 15 days warranty policy in case any thing goes wrong with repair done They would visit for free and look upon the issue.

5 Must have Mozilla Firefox ad-dons for web developers
