Elixir/Ruby Developer (freelance)

$4000 · 10 years of experience · Advanced/Fluent

Поледние 6 лет - работа в мультинациональной Финтек компании в Барселоне, поэтому проблем с удаленной работой и коммуникацией давно не испытываю. Опыт разработки финансовых систем (PCI, интеграция с системами платежей - PayPal, card gateways) в Финтек индустрии с использованием Ruby, последние 2 года преимущественно Elixir. Уверенная работа с любыми Agile процессами. При отсутствии оных, помогу наладить на уровне команды/компании.

Ruby on Rails, Ruby, Elixir, PostgreSQL, Redis, AGILE/SCRUM, MySQL, MongoDB, Machine Learning, PayPal, REST API, AWS

Перевод платежной системы компании с Rails на Elixir/Phoenix, миграция данных. Параллельно, интеграция с новыми платежными провайдерами(Spreedly, PayPal, Slimpay) и новой системой мониторинга(Datadog)

Слаженная команда(3-7 человек), предпочтительно Финтек, относительная свобода в выборе новых технологий, отсутсnвие бюрократии. Барселона/удаленная(критично). Предложения о релокации не рассматриваю на настоящий момент.

Team Lead / Tech Lead / Software Architect

Kyiv · $6000 · 6 years of experience · Advanced/Fluent

I have deep expertise in web development. Mostly I worked with Python (data engineering), Ruby (web development) and JavaScript (frontend). I have a deep AWS knowledge and use their services to save development time when it's possible instead of inventing bicycles or hosting on my own. Besides this, I worked with big-data (ElasticSearch, Redshift) and high-load – I know how to build scalable and reliable solutions. Also, I like DevOps principles, when everything is automated, tested and being monitored.

AWS, Python, Ruby, Architecture, ElasticSearch, PostgreSQL, Redis, Big Data, Docker, Highload, redshift, Git, Linux, SQL

- introduced BI tool in the company - implemented billing calculation for marketplace - development of highly-available services hosted in AWS

Interested in going from a developer role to management. Have a lot of experience in collaboration with product owners and stakeholders, though not very much experience in people management, but want to grow in this field.

I specialize and have deep experience with backend services and infrastructure of highload projects (>5M unique daily visits). Guided a team through a transition to a formal workflow, introduced devops practices, significantly improving development process. Architected and deployed a fair number of performance optimizations. Led a greenfield project (rails and react) from discovery phase to production deployment, establishing team culture and best engineering practices (CI pipeline, pull requests, code reviews, automated style checks, etc). Developed a low-latency network service (scala), an enterprise json-api service (scala), a ruby gem, an e-commerce application (rails), a semi-anonymous imageboard (es2015), an enterprise messaging application (rails, react.js), an MVP of an addiction treatment platform (rails), a real-estate marketplace webapp (rails, react.js), an advertising platform (rails, python, es2015), a CRM webapp (rails). Presently working on real estate and asset management services (rails, node.js, react.js, python, scala, es2017, aws).

Looking for technically challenging problems, which may include, but not limited to highload devops, artificial intelligence, complex UIs, big data, low latency; mature startups, passionate product teams. Not looking for trivial, repetitive, lower-skilled occupations, outsourcing bodyshops.
