I am an experienced Software Developer who enjoys tackling complex problems in an Agile environment. I constantly pull work, so product managers enjoy working with me as I always tackle the tasks that bring in the most value. I began my career as Operations Optimizations Research Assistant, but I switched to software development to build meaningful and impactful products. I have spent most of my career as a backend developer, but I'm no stranger to the Frontend part either, which means I can work full-stack as well. Most of my applications run in the AWS cloud. I've spent most of my career using Java and ReactJS, but I reasonably quickly adjust to any technology. Some of the projects that I've worked on include: - Recording platform that supports millions of transactions daily (Java, Spring Boot, ReactJS, Docker, Hazelcast, AWS) - Voice messages & IVR supporting thousands of transactions daily, providing text to speech campaigns (Java, Spring Boot, Docker, Hazelcast) - Customer Relationship Management (CRM) app for leading Middle-east Telecom company (Java, Spring Boot, Hibernate, Docker) - A mobile app that is a part of an IoT system that includes intelligent devices controlled by the app via BLE protocol as well as IP protocol (Android, JavaScript), - Access Control Optimization - tasked to develop an algorithm for role mining and beat the world's known results at a given instance using a heuristic algorithm that translated this problem into the problem of determining the minimum biclique cover of a bipartite graph (Java); - Development of SCADA system on hydro-power plants - tasked to develop the HMI, and the communication model - Various scripts to automate and speed up manual tasks that are part of my everyday job (Python) Languages and libraries: Java, Spring Boot, Hibernate, Maven, JavaScript, ReactJS, Python, SQL, Docker, Hazelcast Cloud: AWS
