in Portugal

I'm CTO, System Architect, Full-Stack developer with 10+ years of experience. I've experience of building billing systems for Internet Service Providers, Mobile Content Providers, Site Builder Systems (like a SitePlus.com, Wix.com), Learning Management System (cyber-education.az), small tools and etc. stuff. I can work alone or manage a team and work together to keep them enough mentored and motivated. Experience list (developing during work): 1. NodeJS - expert with 5+ years experience (my main serverside script interpreter that I use extensively in projects where high load and low latency is in first place), 2. PHP - expert with 10+ years experience (have rich experience with any popular framework of it, built billing systems and apps that will be supported by other developers where NodeJS devs are few), 3. Rust, C++, C#, Java, Python, Ruby - debugger and had deal with code written on these languages, writing own small projects on Rust as hobby before using it in customer's work. 4. Databases: MySQL (also Galera Cluster) - expert (installing, tuning, replication, complex queries, building optimal db solutions), PostgreSQL - expert (installing, tuning, replication, complex queries, building optimal db solutions), MongoDB - expert (currently preferred as primary db in most of projects, have rich experience on any aspect of this db), CouchBase - expert (using as secondary after MongoDB to cache, store data that is requested with high concurrency), CouchDB - expert (same as CouchBase, but I prefer CouchBase for it's active data in memory principles), RethinkDB - expert (I use it to build back communication between api micro-services and web-socket micro-services to route response to exact connection in context of multi-instance containers) 5. Frontend frameworks: AngularJS, ReactJS - have experience of supporting code written using these frameworks and experience can be developed if there is big need to work with them 6. Building micro-services and dockerizing it - I write micro-services "every day" because it's more compact, stable, flexible, scalable way of shrinking system to modular parts that will not conflict much than monolythic apps 7. Server OSs: ArchLinux, Debian, Alpine 8. Continuous Integration: CI Scripting in GitLab, Jenkins, CloudBuild 9. Team/Task management and boards in Jira 10. Cloud service providers: GCP, AWS For me nothing is impossible. Have problem - I'll find solution, only question is time. I would love the opportunity to work with you on your project!
