I have been working with java for a long time and am entirely comfortable with it. I have been a developer for the last 11+ years and use the following skillset: 1. React / Flutter 2. Spring boot 3. JPA 4. REST API 5. Bootstrap 6. JavaScript 7. Groovy/Grails to help create new/troubleshoot any problems in : 🌟 Developing website/web applications 🌟 Developing back-end applications with Spring Boot 🌟 Developing micro-services with clean architecture. 🌟 Unit testing 🌟 Creating services to work on Docker 🌟 Working with RDBMS (SQL Server, MySQL, etc.) and No-SQL databases (MongoDb/Neo4J) 🌟 Rest API development 🌟 Full Stack development 🌟 Payment Gateway integrations I am looking for a remote work and planning to take it further, with work from clients like you and good reviews, for completing given work to fulfillment and satisfaction and bring: ● 11+ years of professional experience ● Skilled and dedicated professional ● Efficient, hardworking, and highly organized ● Detail-oriented, focused, and motivated ● Communicative and responsible ● Clean, corporate, professional, modern design ● Quality: of course! ● Quick turnaround (you'll always have your project on time) ● Rush work available ● Interaction/feedback on work in progress (iterative model)/SCRUM till you are satisfied. I know you'll probably get a bunch of low bids, but do you really want to risk this project on somebody because they are the lowest bidder? Probably not. You can avoid pitfalls and save yourself time, energy and hassle if you choose a quality developer, with qualifications and most important experience. You want peace of mind, knowing that the job will be done right the first time. But if anything does go wrong, you want to know that your developer will stand by his/her work and complete the project with integrity, interacting with you all the way, to re-design and re-code the solution to your fullest satisfaction, with the best coding practices. So, if you want a dedicated, dependable and person with integrity, who would go the extra mile to give you the best, you have found him right here. So feel free to contact me to discuss your aspirations and designs, which I can code to reality. Thanks for your time. Regards Isteeak

My professional career was mainly in Java, I have 10 years of experience on it, and I mostly covered all the frameworks that run on it, but my favorites are Spring and App Engine SDK. For the last 4yrs I was the Technical Developer Leader, in Prestosports. We worked in a GWT based project to support entries of live plays of +8 sports like football, soccer, and hockey. We built the backend that exported that to XML and a custom binary format. All the APIs were JSON based. I designed and built custom REST APIs for other clients to consume our data, and had to do several important refactors to existing code base. Previously, I worked as CTO & co-founder of Ironsoft in Argentina. I had several tasks on my plate, from HHRR, to training new developers, and design and implement projects. One of our biggest clients was the startup BetterCloud, were we helped them to raise their current success on Google App Engine and GWT, with more than one million of users. I like to work will the complete profesional development suite: * Agile / Kanban * Git / Code Reviews * Jira, Trello * Hipchat / Slack * Maven / Gradle * REST apis * Microservice design & structure * Jenkins / CI * Linux Tools / Shell Script / Automation I also have experience with responsive sites, HTML5/CSS, Angular 2/4/5 and Native Script. Angular 4+ is something I love to work with, and I use for all my hobbies projects. Finally, In my free time, I like to fly gliders, study anything related to finance (and crypto-currencies) and play soccer with friends. Thanks for visiting my profile, looking forward to hear from you!
