Position: Senior Full Stack Developer / Team Lead - React, Node.js
Category: Lead
English level: upper
Years of experience: 9

- Development & ownership of big complex features, big refactorings in a large codebase
- Lead activities, mentorship & team support
- Significant performance improvements (code splitting, caching, progressive loading, improved WebVitals scores)
- Mentored a C# dev from 0 to a decent React dev in 6 months
- Integration of a State Machine to manage UI & logic of a very complex multistep form
- Graceful migration from Javascript to Typescript (significantly reduced a number of common bugs in code by catching errors on compilation early, force interface oriented development)
- Introducing unit & integration testing (with good testing practices such as TestDriver pattern, small maintainable tests)
- Migration of a monolith application to service oriented architecture (SOA) in a monorepo
- Added event-based (async) communication between services in SOA (delays non-essential tasks to background processing, improved real and perceived performance)
- Code all infrastructure in Terraform (full production setup - k8s, networking, databases, etc etc - can be up & running in ~20 minutes on a fresh AWS (or whatever) account)
- Dockerize applications in monorepo (to get rid of "works on my machine" and make deployments predictable) 
- Implemented full CI / CD process in Github Actions instead of Jenkins
- SonarQube integration for automated code reviews
Technical qualifications: 
- Languages: Javascript/Typescript, NodeJS, HTML, CSS, SCSS, prior PHP experience

There are older positions that involve Drupal, PHP, jQuery, etc technologies that are not really relevant anymore, but happy to tell about them if needed.
Would like to work closely with blockchain development (I don't have blockchain development experience at the moment but eager to learn it).

Looking for work/life balance, result oriented approach (vs time-oriented), prefer flat structure, less bureacracy and less useless meetings.

Would like to work with professionals & smart people, ideal when there are learning opportunities.
