    🔥🔥 Looking for remarkable results quickly? You want as less mistakes as possible? 🔥🔥 Working as a full stack developer for years and knowing how to pull hard projects, I can guarantee that you will be 100% satisfied with my results. The procedure I follow that guarantees 100% success rate (Don't believe me? look above at my score!) 1) Understanding the needs and problems you have (free) 2) Thinking & Discussing the best possible solution for your budget & time (free) 3) Creating a blueprint-structure of the application/solution 4) Code & Test everything 5) Support you until I die :P In other words, I plan everything in advance, I give you all the details in a nice and clear pdf document so you know exactly what you are getting. If you agree with my plan, we are ready to start the contract, otherwise we change it and make it meet your requirements and needs! This is also a surprisingly good way to build a MVP (Minimum Viable Product) to have something to work on while you request for updates! Furthermore, it is the best way to avoid mistakes, because you have already checked & planned everything in advance ;) Not A Simple Engineer, but a Ninja! Since I was a little kid I had a passion about technology and science! Flying cars, smart homes, artificial intelligence, time traveling machines or simulation models are some of the projects that I am working on right now or I plan to work in the future! Some of them are IMPOSSIBLE, but it is still fun working on them and learning a lot of things everyday. Currently, I am building a rocket!!! 🔥🔥 First time clients are going to have an amazing offer!!! 🔥🔥 I have years of experience in the following languages: ◉C ◉C++ ◉Python ◉PHP ◉CSS/CSS3/SCSS ◉Javascript ◉HTML/HTML5 ◉SQL ◉NoSQL ◉Assembly (16 & 32 bit) Proficient in the following frameworks & Softwares: ◉Python-Flask ◉NumPy ◉Codeigniter ◉Bootstrap ◉Jquery ◉MySQL ◉MongoDB ◉BeautifulSoup ◉Selenium ◉PhantomJS ◉Chrome (headless or not) ◉Firefox (headless or not) ◉WordPress ◉Joomla ◉ReactJS ◉MeteorJS ◉D3Js I am usually working on: ◉Web/Mobile Applications ◉Data Analysis/Mining/Scrapping Tools ◉Automation Programs & Softwares ◉Security tools Most of the times I make a mix of Automation/Scrappers and APIS. For Example, the most recent automation software that I developed was a Python-Flask API with: 1)Dashboard with basic options like download results,add sites to scrap, delete results etc... 2)Parallel Scrapping multiple sites, who wants a slow scrapper right? 3)Data analysis of the results 5)Login System In case I did not make it clear, I love automation softwares. Especially a mix of an automation connected to an API that can be controlled via a web browser and automatically control multiple little things :P I have also participated in bugcrowd & hackerone bug bounty programs and I have spend many hours in penetration testing labs You made it to the end, I am proud of you :) Feel free to send me a message! Have an astonishing day!
