I engaged in a rewarding side project where I developed native Android and iOS applications as well as a website using Next.js, aimed at individuals who are passionate about hot deals. By exploiting the functional prowess of Spring Boot, Kotlin, and Gradle, I was able to design a robust API for this venture. The platform encourages users to share, follow deals, and have access to promotional codes and discounts, creating an interactive community for deal lovers.

As the lead and developer of the Android development team, I played a substantial role in the successful development of a Kotlin-based utility and self-account management application for Turkcell, Turkey's largest mobile operator.

The highly robust application, benefiting from a 99.8% crash-free rate, effectively satisfies the needs of over 16 million monthly active users, making it one of the top three most downloaded apps in Turkey. My responsibilities encompassed the end-to-end management of the software development process, from conception and design to coding, testing, and maintenance, ensuring its continuous functionality and adaptability to user needs. I utilized my team leadership capabilities and advanced technical expertise in Kotlin and Android development to successfully map out project scopes, tackle complex problems, drive quality assurance, and achieve project goals within stipulated timelines.

As an integral part of the development team, I dynamically contributed to the successful creation of a sophisticated online auction app meticulously built on the Kotlin platform.

This app engages AWS Kinesis to facilitate live streaming, a feature that greatly enhances user experience. Spearheading its Android variant, my involvement branched out to several crucial areas. I strategically utilized WebSockets to take charge of messaging and receiving bids, emphasizing smooth, real-time communication across the platform. My expertise was also employed in the implementation of in-app purchases for credit acquisition, further simplifying user engagement. Each of these elements was galvanized towards generating a transformative, seamless, and interactive application that revolutionized online bidding in the Android environment. By constantly synchronizing the interactive, monetary, and communication components, I effectively drove the project's successful development.

I was instrumental in developing a comprehensive Kotlin-based Android SDK for Turkcell, a robust telecommunications provider. This project encompassed the design and implementation of an integral login feature widely utilized across numerous Turkcell applications. The SDK was conceptualized with a unique chaining feature, automating the login process for applications within the same category, greatly enhancing user experience and operational efficiency. A defining aspect of this project was creating customizable UI elements, which were dynamically adaptable to meet the varying design and functionality needs of different applications. This ensured a flexible and versatile toolkit for designing uniquely differentiated applications under the Turkcell brand. This SDK played a pivotal role in bolstering user engagement across multiple applications through streamlined login processes and enhanced UI personalization.

I was instrumental in the successful development of a bug report SDK for Turkcell. Drawn from the Android platform, I leveraged the power of the Kotlin language to create an Instabug-inspired tool aimed at enhancing efficiency for system testers.

The SDK integrated seamlessly with project management platforms such as Jira and Trello. This integration allows testers to effortlessly commence a task with indispensable information like images and priority level among others. The process initiation is quite user-friendly and intuitive, necessitating merely a screenshot to set in motion. Optimizing simplicity, quality, and productivity were at the core of this project. I ensured these by playing a key role in all the development stages, from conceptualization and design to the successful implementation of this modern and efficient bug report SDK.

In my role at Turkcell, I functioned as the lead developer on a distinctive project, crafting a Kotlin-based app intended for elite users. The app, with over 3 million downloads and over 500 thousand monthly active users, was designed to provide special promotions, discounts, and exclusive offers wrapped in a sophisticated UI design, seamlessly integrated with engaging animations. My responsibilities encapsulated not only leading the project execution but also expressing myself in the capacity of the chief Android developer. A pivotal part of my role was to incorporate essential features that empower users with complete oversight over their account management. Through my leadership, we successfully launched an app that pushes the boundaries of customer satisfaction, distinguishes its users, and sustains a robust following. The success of this project stands as a testament to my dedication and proficiency in software development.

As the sole Android developer for a sophisticated Java-based application designed for Turkcell's corporate clientele, my focus was on streamlining the management of the company's communication lines. The core architecture of the project was implemented using Java. I had the exclusive opportunity to drive the project and demonstrate my expertise in Android development throughout the process.

As part of our tech evolution initiative, the inclusion of modern features was necessitated. Thus, I extended my role to not only maintain the existing Java codebase but also complement it by adding new features using Kotlin. This included assessing the needs of our corporate customers, designing features accordingly, and seeing them through to successful integration. Overall, my instrumental role managed comprehensive app design to successful deployment, highlighting my ability to work independently and effectively weave together multiple programming languages to accomplish the project goals.

I successfully developed an advanced iOS widget application, leveraging the SwiftUI framework, designed to simplify vehicle tracking and parking. This intricate app provides users the ability to effortlessly record and save their parking locations, either via direct location data or through photographic references.

The utility of this app stands out with an additional feature of tracking the elapsed parking duration, ensuring careful adherence to potential parking time restrictions. More complex yet user-friendly, the app comes with a customizable widget available in three different aesthetically pleasing sizes, which aids users in visually locating their parked vehicles without entering the app. This meticulously designed functionality incorporates a seamless amalgamation of precision location tracking and visual photo references, thereby providing an unmatched user experience for vehicle park tracking. This app stands as a testament to my technical prowess in iOS app development and user-centered design approach, with a focus on delivering practical, intuitive solutions for everyday issues.

The project revolved around the development of a sophisticated social media application based on Java and Kotlin. As the sole Android developer, I was entrusted with the full cycle of application development, from initial planning to final deployment. This dynamic app boasts a multi-module architecture framed with an MVVM design pattern, ensuring an efficient, structured, and scalable solution.

The app supports a host of different post types for display and sharing, thus enriching user interactions and engagement. To heighten the real-time experience, it also incorporates "push notifications" and "sockets," providing users with instant updates and communication abilities.

My responsibilities spanned understanding project requirements, drafting the architecture layout, writing clean, efficient code for disruptive features, and conducting rigorous testing to ensure the top-notch usability of the app. I also worked on debugging, fixing bugs, and rolling out updates as needed. The successful deployment of this application largely underscores my capabilities as a dedicated Android developer.

Implemented a music streaming application, similar to Spotify, using Kotlin as the primary programming language. As the lead Android developer, I efficiently drove the project from its inception to completion within a stringent timeline. Expertly engineered 80% of the application using Jetpack Compose, exhibiting superior coding proficiency and project management skills.
