Jodel is a mobile hyper-local community social media app connecting users and the local community.

I acted as a full-stack developer in the monetization team, creating new features for premium users and developing internal ads management tool for the app.

A micro-service used as an adapter between two crucial services of the insurance sales application. Implemented as an AWS Lambda function with Snowflake, DynamoDB, and other AWS Services, the entire infrastructure was defined as a code. I delivered the final product with complete code test coverage and documentation. I have been the main and only developer working on this app. I went through the entire software development process, from specifying requirements, conducting workshops, writing deliverables, and implementation to production deployment.

The app's responsibility was to accept input, decorate it with the external data from the Snowflake data lake, and map it to the expected output format using rules defined in the control tables.

After development, I managed to drastically improve the performance for the big inputs using a subscriber design pattern.

Engaged in building an internal company communication system used by over 100,000 people. Implemented with Spring Boot (back-end), Thymeleaf, and Vue.js (front-end)

The system is used to schedule and manage meetings and provides functionality to use and manage conference room devices. Users were able to check the availability of the device and book it for their next meeting. I was one of the main authors of that feature.

After I learned modern UI frameworks, I prepared the PoC of the UI in React and Vue.js and convinced the product team to transition from the old VanillaJS front-end to Vue for the benefit of all. I prepared documents with components architecture, helped plan the workload, and spearheaded the development process.

Besides implementing new functionalities and fixing bugs, I was also in charge of preparing monthly code quality reports using SonarQube and Istanbul.
