Software Developer in Bucharest, Romania

An Android app for food delivery and takeaway.

I was an Android software engineer working as part of a cross-functional team on the order journey section of the app.

LATCH Intercom is an intercom product designed for building entrances that allows residents to receive audio calls at any US telephone number.

As the sole Android app engineer, I was architected and implemented the intercom’s core app.

Since this is an always-on product, it came with various challenges that are not encountered when developing regular Android apps. As a result, I had to spend more time profiling the app, building redundancy into the system, and setting up error detection and self-recovery systems.

Among the other notable requirements that I implemented were VoIP calls, BLE both in central and peripheral modes, and app to back-end communication via MQTT.

Latch App is an Android app that complements the company’s smart devices. It allows users to configure their devices, unlock doors, and receive VoIP calls from the Latch Intercom.

I worked on developing the app’s voice and video calling features.

SmartMobile is Raiffeisen Bank's mobile banking solution.

As the lead developer, I architected the app from the ground up, from implementing critical features (authentication, authorization, payments) and enforcing security best practices to delegating tasks to other Android engineers.

Another interesting feature that I had to implement was the app’s widget.

Ticketscript is a box office app for the selling and printing of tickets. I built this mobile POS app and implemented the Adyen payments SDK. Ticket printing was done using StarMicronics printers; for this purpose, the Star Micronics SDK was integrated.

Ticketscript Flow is an app used for event-entrance management by scanning ticket barcodes.

It has an exciting offline feature to sync scanning between devices in places without internet coverage. For this purpose, I developed a system similar to Apple Bonjour.

It could handle many records, up to 100,000 tickets stored for offline validation.

The mobile app gives customers access to Allianz-Tiriac insurance contracts, private pension products, damage claim status, and insurance premium payments. Customers can also file claims and acquire travel insurance, vehicle insurance, and road vignettes.
