I can teach you Go, from ground-zero to become a paid professional. Wanna learn about Concurrency? Interfaces? Deferred Funcs? Embedding? Composition? Go software design? No problem. I can teach you all. My experience with Go: + I'm the author of popular Go blog: https://blog.learngoprogramming.com I built: + Concurrent and scalable real-time backend APIs with REST and gRPC. + Cross-Platform Command-Line Apps + Fast Json/XML parsers and data crunchers + Scrapers, crawlers + Web apps, database backed apps etc. And many more.

I've done many successful code reviews for many teams across the world. We sign an NDA and good to go. I can inspect your codebase or a small part of your app to create a code review documentation and annotations on your code. I'll provide: - are you doing ok? - are there any problematic parts in your code? - what are your tech debts? how can you fix them? - what would be better if you do something else? - performance problems - automation problems - re-structuring, architecture and general advice - suggestions on your tests - and other suggestions depending on your needs

I designed and developed web-scale messaging and analytics systems in the cloud with node.js which process hundreds of millions of requests daily. Using it in everyday life whenever performance or an API is necessary.

I've been breathing with javascript for 20+ years. I'm very knowledgeable about OOP and design in js and can fluently code in ES6 and ES7. I've been using js for client side, server side; I've been developing full-stack Javascript apps. Started with it on making my web applications dynamic back in 1995s. I've created javascript only search engines, UI utilities like drag drop. That was times when there is no jquery or something, so we were doing most of the thing manually. Great times. Then, came jquery, I've been using it for everything since its first release. Also, using its alternatives, micro-libraries or directly modern browser DOM utilities (vanilla js movement).

I have decent experience with React such as building components for analytics dashboards. Huge ecosystem.

Ruby is simple and to the point. I'm aware of its pitfalls and brilliance. Duck typing, patterns, and metaprogramming, etc.

I'm a Ruby on Rails, Sinatra, RSpec expert. I'm currently the top %8 Ruby developer on the stackoverflow. From installation on various operating systems to working with it through rspec and cucumber. Created analytics dashboards, management dashboards, websites, apps for platforms like Facebook and created many background workers that take the heat off of the system.

Testing is my middle name. I've very in-depth knowledge of testing, from functions, classes to full apps in any environment. And, I can teach you that hard-earned experience.

I've been managing databases for 20 years. Started with Microsoft Access and then SQL Server, MySql, PostgreSQL, SQLite and continued with NoSQL databases like Redis, MongoDB. I've even created my no name database systems for the needs of the projects that I'd been developing. Tuned hundreds of millions of rows databases. Created databases for real-time response needs etc. Also, created caching solutions for all of the databases that I've described so far. So, I'm very OK with database optimization too. I've created many complex SQL queries and tuned them to the last bit of CPU cycle / IO operation.

I created automatization solutions like builders, deployers, background jobs, etc. Also, I've experienced in administrating Linux servers.

I can automize coding, deployment, monitoring, testing etc. I can deploy and test servers automatically. I can create staging and production servers. Or I can make systems deploy and test themselves continuously.

I'm not only using editors, I program them and bend them to my will :)

I've been launching and managing many web scale product from zero to one using agile and lean methodologies. I'm an experienced agile coach, scrum master and product owner for a lot of teams. I know how to write very concise user stories, how to adapt teams to agile, how to plan a project and product, etc. I know how to make a product a reality.
