OLX - App Monolith Separation and Redesign
At OLX (a company of Prosus Group), I planned and delivered the separation of the mobile monolith into microservices related to each product team.
Product Summary
Split the Mobile API Monolith into four new independent end-to-end modules.
When I worked at OLX, the company used the API/Next Gen (Mobile solution inherited from Schibsted) to connect the Apps and the Database content. The API was a single code platform that our team refactored and split into four modules according to the context of the following vertical squads:
-
Paid Product
-
Ad Insertion
-
Chat
-
Account Creation.
​
By delivering the code separated in new APIs, the teams mentioned above could work independently of the old Monolith, which improved the development speed and allowed the teams to make several deploys whenever they wanted to.
In other words, OLX teams don't have to wait for the other teams' deployment approval. Now they can work on small independent modules (endpoints).
Paid Gallery Redesign
First, I used SQL queries to measure our paid products' liquidity, connectivity, and visits. The main goals were monitoring, understanding, and having more insights into OLX products' performance. Then I analyzed 3 KPIS/Metrics, the Reply Average per Sold Product, the Liquidity Average per Sold Product, and the Visits Average per Sold Product.
​
I created a new metric called Liquivity, which is liquidity (average of paid products flagged as sold) on Connectivity (Number of messages average per product sold), so I realized that the Gallery had the worst performance for the users. Then I made online surveys to understand the buyers' and the sellers' perspectives on the subject.
​
Through user tests and online surveys, I discovered that the Gallery didn't attract the buyer, and worst, they thought the product was an advertisement (like a banner). So, I talked and aligned with the Designers, and we began to redesign all the products to attract more buyers and, at the same time, help the users/sellers who paid for the Gallery to make a deal and sell.
I also aligned with the front end and the two backends to understand if it was hard to code the new design users chose through the three options we showed in the online survey.
​
The result was that the new Gallery increased the total monthly Revenue by 13% in the next three months, another good outcome was that the CTR of the new Gallery (compared to the old one) increased by 18%, and users' satisfaction with the sellers grew by 29%.
My Participation and Results
I led two squads as PO at OLX, the Mobile APP squad called SSS (Scalability, Security, and Structure) and the Paid Product team. Through this leadership, I was able to reach the following results:​
-
Split the Mobile API Monolith into four new independent end-to-end modules, which allowed squads to work with autonomy and upload their deploys;
-
Redesign the Paid Product - Gallery, which led OLX to the following results:
-
Increased the total monthly Revenue by 13%;
-
CTR of the new Gallery (compared to the old one) increased by 18%;
-
Users' satisfaction with sellers grew by 29%.
