A C# console application designed to apply a lowpass filter to images, 产生视觉上吸引人的模糊效果. The application allows users to experiment with picture blurring using different window sizes.

This console application uses a straightforward approach to blur images. 通过指定图像路径和模糊的窗口大小, 用户可以运行代码并生成新的模糊图像. The application does not include production-ready features such as exception handling or performance optimizations. It was developed as a fun, one-night-stand project to create a simple image-blurring application.

A project management system I designed and developed for internal use in the company I worked for as a junior developer.

它是为管理瀑布项目而构建的. 项目可以被分成许多嵌套的子模块, and each module can be assigned to teams and developers with specific deadlines and milestones. Every project piece also accepted all kinds of documentation to work on. Later on, the solution also integrated announcement and chat modules.

An enterprise file-sharing (EFS) solution I've worked on as a lead engineer from its conception for four years.

EFS是面向企业客户的SaaS解决方案. It encompassed web, native iOS, Android mobile, and desktop client applications. Its primary objective was to empower clients to seamlessly integrate and manage their users through LDAP, Active Directory, 或者我们专用的管理端点.

The EFS provided end users with a plethora of modern features that were a delight to develop. 其中包括选择性同步, 实时文件同步, delta sync, 本地邻居客户端P2P同步, deduplication, 版本历史操作.

A route optimization project I undertook for one of the biggest shipping companies in Turkey, Yurtiçi Kargo. 我已经处理了它的设计阶段.

We developed a convex hull heuristic with capacity and 2-opt and 3-opt optimization algorithms. The heuristic aimed to increase the efficiency of cargo trucks' daily routes. Trucks had volume capacities, constrained working hours, and legally allowed working area borders. We then managed to increase the efficiency by an average of 33% for a relatively large branch in İzmir with three months of historical data. Unfortunately, the project was never launched due to business conflicts.

An online exam platform I designed and developed for a local education consultancy firm as a freelance developer.

总部注册的分支机构均可使用该平台. Each branch could register new students with the codes provided by the main office. The administrative branches were able to create a variety of tests. The supported test types were regular tests with a time limit for the whole test, 记忆测试用文字或图像来记忆一段时间, 每个项目有多个定时问题, and Likert scale tests. 在创建测试之后, registered students were given these exams according to the improvement path they bought and their age group. 在完成每次考试后的一段时间后, a higher level test was presented to the student to monitor their improvements.

Another enterprise file-sharing (EFS) solution to which I've contributed as a lead engineer, 贯穿设计和开发阶段.

This version was an on-premise solution marketed to corporate clients with their own data centers and file systems. 与上面提到的SaaS不同, it lacks a desktop application as all the end users were in the intranet and used the existing file system. 与NTFS和NetApp集成, the web and mobile applications worked on top of the existing file system, 利用所有现有的功能, 例如权限和快照操作. 根据管理用户定义的规则, users could share files and folders outside the company via shareable online links. Also, administrative users could see and generate usage and sharing reports for all users, 哪个功能受到官方机构的欢迎.

For me, the most fun feature it had was an online document editing tool where users could collaborate on the shared office documents in real time.

为联合利华食品解决方案(UFS)开发的项目, 我在一个敏捷的远程团队中工作.

We handled the entire development process of UFS, from its back office to the B2B webshop. 利用强大的CMS平台Adobe Experience Manager, I played a pivotal role in developing new components and ensuring the smooth operation of existing functionalities as part of the innovative UFS team.

致力于这个企业级项目, 它迎合了大约50个国家的需求, 是一次愉快的经历.

A project related to my wife's master's thesis targeting a web-based remote sensing application to which I've contributed as a graduate student.

I developed a few filtering and clustering algorithms used in remote sensing satellite images, such as low-pass filters, mean filters, median filters, high-pass filters, Laplacian filters, Sobel filters, 无监督聚类算法, and KMeans clustering. Additionally, I developed a user-friendly library to play with band combinations of a satellite image for this project using GDAL.

A project related to my master's thesis in which I designed and developed a distributed self-stabilizing simulator.

Distributed algorithms are hard to design and test since they require many distinct processors to work on. Self-stabilizing ones are even harder as the system has to be alive in real time while some processors are born, and some are dying. In order to ease out the development and testing processes of distributed algorithms, I developed a thread-based self-stabilizing distributed simulator. This tool can either be used for developing or testing new algorithms or going through the execution of an algorithm step-by-step for educational purposes. We also published this work as an academic paper at a local conference.

A project that comprised the investigation of the practical performance measures of all three known distributed self-stabilizing dominating set algorithms using the SELFSIM I developed. 研究结果发表在当地的IEEE会议上.

一本尚未出版的《欧博体育app下载》, Cloud Computing, 和无线网络优化”. I wrote one of its chapters related to my master's thesis—"Capacitated Graph Theoretical Algorithms for Energy Efficient Wireless Sensor and Ad Hoc Networks."
