  • Project Management System

    I designed and developed a project management system which was used internally in the company I worked for when I was a junior developer. It was built for managing waterfall projects. The projects can be separated into many nested submodules, each module can be assigned to teams and developers with specific deadlines along with milestones and etc. Also, every piece of the project was accepting all kinds of documentation to work on. Later, announcement and chat modules have been integrated into the solution as well.

  • Enterprise File Sharing (SaaS): fileorbis

    I worked in the design and development phases of an enterprise file-sharing (EFS) solution as a lead engineer from its conception for four years. EFS was a SaaS solution marketed to corporate clients. It had web, native iOS, and Android mobile and desktop client applications. While clients can integrate and administer (assign quotas, handle immediate off-boardings, etc.) their own users through their LDAP or Active Directory or through our administrative endpoint. End users were capable of taking advantage of many modern features of an EFS, which were a real joy to develop: selective sync, real-time file synchronization, delta sync, P2P synchronization (for local neighbor clients), and deduplication, along with version history operations.

  • Route Optimization

    I worked on the design phase of a route optimization project for one of the biggest shipping companies in Turkey (Yurtiçi Kargo). We developed a heuristic using a convex hull with capacity and 2-opt and 3-opt optimization algorithms. The heuristic aimed to increase the efficiency of the daily routes of the cargo trucks. Trucks had volume capacities, constrained working hours, and legally allowed working area borders. We then managed to increase the efficiency by 33% on average for a relatively large branch in İzmir with three months of historical data. Unfortunately, the project was never launched due to business conflicts.

  • NeroHealth - Online Exam Platform

    I designed and developed an online exam platform for a local education consultancy firm as a freelance developer. The platform can be used by registered branches of the main office. Each branch can 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, memory tests with items to memorize (either text or image) for a period of time, multiple time boxed questions for each item, and Likert scale tests. After the tests were created, registered students, according to the improvement path they bought and their age group, were presented with these exams. After a certain period upon completing each exam, a higher level test was presented to the student to monitor his/her improvements.

  • Enterprise File Sharing (On-premise): fileorbis

    As a lead engineer, I worked on the design and development phases of another version of the enterprise file-sharing (EFS) solution. This version was an on-premise solution marketed to corporate clients with their own data centers and file systems. Unlike the SaaS mentioned above, it lacks the desktop application as all the end users are in the intranet and use the existing file system. Integrated with the NTFS and NetApp, web and mobile applications work on top of the existing file system utilizing all existing functionalities, such as permissions and snapshot operations. According to the rules the administrative users defined, users can share files and folders between each other and outside of the company via shareable online links. Also, administrative users are able to see and generate usage and sharing reports for all users, which was a well-received feature by official institutions. To 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.

  • Unilever Food Solutions

    I worked as part of an agile and remote team for Unilever Food Solutions (UFS). We handled the entire development process of UFS from its back office to B2B webshop. Mostly empowered with leading CMS platform Adobe Experience Manager, I was responsible for developing new components and maintaining existing functionalities as part of the innovation team for UFS. Working on a multi-tenant (around 50 countries) enterprise level project like this was a lot of fun.

  • Web-based Remote Sensing Application

    I worked as a graduate student on this project and teamed up with my wife for her master's thesis. I developed a few filtering and clustering algorithms used in remote sensing satellite images such as low-pass filters - mean filter, median filter, high-pass filters, Laplacian filter, Sobel filter, unsupervised clustering algorithm, and KMeans clustering. Also, I developed a user-friendly library to play with band combinations of a satellite image for this project using GDAL.

  • SELFSIM: A Discrete-event Simulator for Distributed Self-stabilizing Algorithms

    I designed and developed a distributed self-stabilizing simulator for my master's thesis. 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.

  • Performance Evaluation of Distributed Self-stabilizing Dominating Set Algorithms in WSNs

    I investigated the practical performance measures of all three known distributed self-stabilizing dominating set algorithms using the SELFSIM I developed. The results are published at a local IEEE conference.

  • Book Chapter: Capacitated Graph Theoretical Algorithms for Energy Efficient WSN and Ad Hoc Networks

    I contributed to a not-yet-published book "Handbook of Research on the IoT, Cloud Computing, and Wireless Network Optimization" for its chapter related to my master's thesis—"Capacitated Graph Theoretical Algorithms for Energy Efficient Wireless Sensor and Ad Hoc Networks."
