After winning the ClimateLaunchpad national final we got the tickets to enter the stage 2 of EIT Climate-KIC Accelerator. This stage includes several tasks, such as attracting potential customers, develop a prototype for our solution, and deliver the first operational results for our product. We have secured a €20.000 budget for staffing, travel/ subsistence, and consumables/services costs.
Ag Catalytic Solutions -- Ballast Water Treatment System.
EIT Climate-KIC Accelerator is Europe’s largest cleantech accelerator for early stage startups which is focused upon getting them ready for their first customers, helping them fine tune and scale their business and be ready for investors. We won the 1st prize at the national final and took the tickets to the global final in Amsterdam. During the training phase we have learned how to conduct a proper market analysis, finding our beachhead market, perform market segmentation, and develop a detailed business plan.
Special Scientist / Research Associate.
Ecofy is a startup company that revolutionized the recycling process through crowdsourcing and gamification. We have created a smart recycling platform for promoting recycling by giving people inceptives. People who recycle can earn different rewards on products and services. I have been personally involved in all cycles of software development including problem definition and problem analysis, needs and requirements analysis, software development (back-end and front-end project development using MySQL for database, PHP for API and Ionic framework (Typescript, CSS and HTML) for the smartphone application), testing and debugging and finally maintenance. Our startup was hosted by IDEA incubator - accelerator.
Business Courses, IDEA Accelerator training, which is an incubator program with entrepreneurial activities, business and marketing courses for startup companies.
Participated in the King Abdullah University of Science and Technology (KAUST) Winter Enrichment Program (WEP) Poster Competition. My personal research submission, on protein secondary structure prediction using artificial neural networks and Gabor filters, was chosen out of a very competitive pool of students from around the world. Visited KAUST university in Jeddah, Saudi Arabia, and participated in the final contest for selecting the most innovate and applicable idea to be funded by KAUST university.
Summer intern at Cyber Security/Risk department of Deloitte Ltd Limassol. The internship was about expanding as well as refactoring the warberry tool. WarBerryPi was built to be used as a hardware implant during red teaming scenarios where we want to obtain as much information as possible in a short period of time with being as stealth as possible. Just find a network port and plug it in. The scripts have been designed in a way that the approach is targeted to avoid noise in the network that could lead to detection and to be as efficient as possible. The WarBerry script is a collection of scanning tools put together to provide that functionality. The internship was about expanding the current free and paid version of warberry tool. Paid version includes hacking tools and scripts for attacking vulnerable network spots once they have been detected. Encryption of data and results was also developed. Warberry is a network scanning/hacking tool for cyber security purposes.
