Kraken is an IoT middleware that can connect thousand of connected devices thanks to it's horizontally scalable design.

RFID, barcode, Bluetooth devices are connected to local nodes to form a network of parallel computation network. Inputs are analyzed, persisted and distributed to different integration channels such as SAP.

It can track assets and personnels, determine the directionality of a moving object, take stocks and much more.

Device management, device connectivity, notifications and integrations are managed in a web application.

Kraken is used by the largest manufacturers, banks and city hospitals in Turkey to automate their processes using IoT.

I was a partner of the company and I acted as the architect, the team leader and the product manager of the system.

Detaware is a suite of applications and services that allows the assets to be created and tracked using IoT technologies like RFID and barcode. It has integrations to applications like SAP and Logo so that asset tracking information is always in sync.

It reduces the human error dramatically and speeds up the tracking and inventory taking process by more than 95%. It achieves hundreds of assets to be inventoried per second.

Detaware is used by largest banks, universities and manufacturers in Turkey.

Matrix Warehouse is the first and most advanced IoT enabled warehouse system that automates warehouse operations without any human intervention. It prevents incorrect order deliveries, violation of FIFO rules, violation of workplace security practices and greatly increases the visibility of operations in the warehouse.

A custom designed IoT system consisting of RFID technology and sensors are installed on forklifts and RFID tags are installed on warehouse addresses and goods. The systems on the forklifts are communicating with a central system that aggregates all the data, process it and integrate with ERP solutions like SAP.

Matrix Warehouse is used by more than 10 factories of Şişecam in Turkey, Russia and Europe.

Markarar is a system that allows the user to scan the barcode of a product using a smartphone and providing information about the product, the prices and the user reviews.

The data is gathered through an innovative scraping method. User's smartphone gets the scrape job, processes it and the scraped data is sent to the server. This prevents blocking of the server IP address due to excessive amount of scraping request.

I was the founder, the designer and the developer of the system. I was also managing a team of 3 others for advertising, UI/UX design.

Defined.ai is a crowdsource platform that pays the crowd for training AI models. I was responsible for designing and implementing payment processes of the crowd members.

I researched and developed payment integrations for Paypal and Payoneer. I optimized the microservice to increase the throughput dramatically.

I designed and implemented a caching system in front of Google Matrix API to reduce the cost and the response time.

The caching system produces response times under 100 ms consistently for more than 99% of requests and reduces the cost by 90%.

I was the leader of a team responsible for development and support of a highly complex speech analytics web application and backend services.

I introduced training sessions for developers, conducted job interviews and evaluated employee performances.

I profiled the applicaton and the services to find and fix performance issues as the services consumed huge amounts of real time streaming data.

I designed and implemented new features. I migrated the legacy monolithic application into a new microservice architecture, updated the framework and library dependencies.

The system was used by the largest banks and telecommunication companies in Turkey, Europe, Russia and Africa.
