I worked as an Android engineer contributing to a large-scale consumer application used by millions of daily active users. I focused on building and improving customer-facing features within an established, highly modular architecture. I worked primarily in Kotlin, leveraging modern Android components such as Jetpack, Coroutines, and reactive streams to implement scalable, maintainable solutions.

An online payment system that allows individuals and businesses to securely and conveniently send and receive money electronically. PayPal allows users to link their bank accounts, debit cards, or credit cards to make online purchases or transfer payments to other PayPal accounts. It is widely used for eCommerce transactions, online auctions, and peer-to-peer payments.

At Amazon, I worked as an Android engineer, contributing to large-scale consumer applications that met high reliability and performance standards.
I developed features in Kotlin within a structured, modular architecture, following strict engineering guidelines around scalability, maintainability, and operational excellence. Given Amazon’s scale, even incremental changes required careful design, thorough code reviews, and long-term thinking.
I collaborated closely with product managers, designers, back-end engineers, and QA to deliver features end-to-end—from technical design discussions through implementation and production rollout. The environment emphasized ownership, quality, and measurable impact, which strongly shaped how I approach Android engineering today.
