SKILLS
With over 4 years of experience, I help companies around the world design and implement their software solutions.
Only interested in remote work.

On the technical side, I enjoy working with Java, Spring (Boot), JHipster, NodeJS, REST, Linux, Unix, Javascript, Angular, Microservices, AWS services, SQL, MongoDB and I know my way around Computer Vision technologies.
I love a good technical challenge.

I work as a consultant/contractor/freelancer and help businesses develop their enterprise products.

My programming language of choice is Java (backend solutions using mainly Spring framework and JHipster generator) but I have also worked with Angular, Javascript, NodeJS and Computer Vision technologies when needed. I am continuously looking for new challenges and self-improvement.

Some projects that I have the pleasure to work on:

• Amazon Fake Reviews detection Tool
The client had a problem to determine the fake reviews rate for a specific product from Amazon.
I created a solution to save all reviews for a product by extracting 1000 reviews per second with 100% precision by implementing an amazon crawler using Java and Node.js and stored the data in MongoDB for quick access. The solution was based on artificial intelligence and the extracted data from the crawler.
Main skills used: Java 8, NodeJs, MongoDB

• Hotmark - https://www.hotmark.io/
My client needed an automated payment system for his platform, an easy way to manage all contracts and accounts and a chat system.
I improved the platform by saving 8h of manual work for every change of the contract type and saving 20h/week of manual work by implementing a tool that can be used to change the plan price and create specific offers, by integrating Bluesnap as a payment processor and Intercom as a chat system using Java with Spring and JHipster and by creating a management wizard using Angular.
Skills used: Java 8, Spring Framework, JHipster, Angular 7, MySql, Javascript, HTML, CSS, and best QA and. Selenium testing.

• Panel Vision
The client needed a solution to extract data from certificate pinned apps like Facebook, YouTube or Instagram.
I created a solution to save all reviews for a product by extracting 1000 reviews per second with 100% precision by implementing an amazon crawler using Java and Node.js and stored the data in MongoDB for quick access. The solution was based on artificial intelligence and the extracted data from the crawler.

• Panelist Traffic Scanner for AdClarity
My client needed a solution to optimize and reduce the time to process traffic data.
I improved the panelist traffic flow by reducing the processing time from 2 days to 4 hours for 50GB of data by implementing the first layer using shell scripting and Java and by automating the entire process using RabbitMQ messages, REST API calls, and logs.
Skills used: Java 8, Spring Framework, JHipster, REST API, RabbitMQ MySql, Shell Scripting, and best QA and testing conventions.

• IOS app Downloader
My client needed a solution to download multiple versions of IOS applications from the App Store.
I designed the solution by developing a system capable of saving and versioning specific applications with minimal manual intervention in just 3 minutes per application by researching the IOS system, methods of jailbreaking and the specific properties of an IOS application and by using shell scripting skills and a Jailbreak device with IOS version 12.4.
This system allows the user to install and use the app later, even when that specific version of the app will not be any more available on the store.
