Detail- Oriented ESL test and training materials

Japan - Last active: 14 hours ago

An American national living in Japan, I focus on cultural awareness and international communication. My background as an ESL teacher and as an interpreter for a travel agency gave me the opportunity to work with individuals from around the world. These experiences help in writing concise, clear ESL teaching materials and practical tests with logical explanations for the answers. Now I work from home so that I can take care of my young son. I take pride in professionalism; high-quality, level-appropriate English; and attention to detail. I have a black belt in judo and am interested in textile arts. In addition to academic work, I enjoy writing about my hobbies and about Japan; not flat stereotypes, but real experiences from living in a foreign culture today.

Sr. IT/Software Development (Project) Management

Italy - Last active: 14 hours ago - Tests: 10

- Sr. QA Engineer - Sr. Project / Program Manager / Scrum Master - Sr. Business Consultant After years of experience in Management in both the Software Development and IT industry, I want to expand my horizon at my level of expertise. I'm more geared towards management of technical staff and/or projects. In this setting I have experience in a lot of different specialties (QA, Customer Support, Web Development, Development, IT, Production, Client Management, and others). I'm comfortable in a lot of environments, but I like to be able to use my own management style that is more aimed in managing through positive experiences, openness and coaching and training. I'm definitely not a supporter/believer of managing with an iron fist. My main aim is always to create a positive and productive environment in which people can feel happy and flourish, as opposed to being stressed and strained. I learn quickly and I'm flexible and precise in my work. I have experience with multiple cultures and am a good communicator.

Planing, Design and Development of iOS Apps

Japan - Last active: 14 hours ago - Tests: 1 - Portfolio: 7

My name is Tonriké, or Toto for short. I'm independent freelance iOS developer and designer based in beautiful city of Kanazawa in Japan. I help companies and entrepreneurs to plan, design and develop iOS applications, usually — from scratch. This covers everything from information in-take, analysis and architecture to application prototypes, user-interface design and software development. I also offer those services separately; however, I will not do UI design without comprehensive UX consulting. Technically, my skill-set covers anything from iOS Foundation frameworks to advanced topics like image processing and digital signal analysis. I already develop and help community to research Swift Language and latest Apple technologies. My experience as iOS developer starts right after iPhone SDK was debuted in 2008. Fascinated by product design and information architecture, I also started to design user interfaces and planing software products in 2009. In 2013 I was offered to teach "User Interfaces for Programmers" in Caucasus University in my hometown, Tbilisi, Georgia. That's what I did and as result, ended up creating whole syllabus which is still in use by university. I'm also fluent with many other technologies around those languages: Ruby, JavaScript, Go-lang. I charge what I charge because I'm one of the best in business, and results I provide are not disposable. "Fire and forget" is not my style of working and many returning clients are prove to that. I do not accept "I need Instagram clone for $1000" jobs, those are for scammers and "developers" desperate to ruin their reputation for little money. In short: If you want high quality, fully-working, maintainable and well-planned product with pre-development consulting and proper design, than contact me.
