Software Engineer

Because I like Emacs, I've been forced to learn Emacs Lisp and Common Lisp. I really enjoy work with the dialects of lisp. But this is just for fun. I have commercial experience with Ruby, Ruby on Rails, Python and even with PHP. But I do not like to work with the last one. I have worked with the Postgres, Mongo, and MySQL, and Redis, but I cannot say that I am an expert in the databases. Oh, and I've taken part in the POC with Rust, RoR, and Python. We've created pipelines for the Airflow, use RoR as API, and Rust as backend. I would like to create programs using Rust. It's an awesome language. I've been participating in the oauth2 server development in python. Also, I've created the plugins for Splunk in python. One of them was the plugin to retrieve SAP matrics via OData2 protocol. And I like to test my programs.

- mentor - experience with high load projects (~10K req/sec) - costs optimization activity (AWS) - good knowledge of SQL - Gitlab CI/Docker Swarm setup/configure - implement monitoring systems like InfluxDB/telegraf/Grafana/Loki/Pagerduty etc. - SOA design, resolve of architecture issues - used AWS (ruby sdk) like Kinesis, SNS/SQS queues, DynamoDB, Redshift, self-hosted PostgreSQL (~10Tb), Lambdas, S3, ASG - Trailblazer 2 (start new projects, implement features)

Ruby on Rails, PostgreSQL, ReactJS, Git, Trailblazer, Docker, Microservices, Gitlab, CI, GraphQL, JSON API, AWS: DynamoDB, AWS:KInesis, AWS: SNS/SQS, AWS:ASG/EC2, AWS:Redshift, AWS:Lambda, AWS:S3/Glacier, CQRS, Blockchain, Docker Swarm

I will be happy to work with product that is working on AWS infrastructure, is high-load and has high proficient team. I like Trailblazer-2 as well, so I would be twice as happy to work with projects which were building on Trailblazer-2 or have plans to use this architecture.

Ruby On Rails Developer 

Lviv · $3800 · 6 years of experience · Upper Intermediate

I've used mostly Rails in the backend and vanilla JS or jQuery in the frontend. I only used Angular 1 in my first project as a frontend framework. I wrote many complex sql queries for the tasks ORM's can't accomplish. I wrote system, integration and unit tests on many different projects. I used Node.js for about 1 year. I mostly worked in small teams or alone. But in one project where there was relatively more developers I was the team lead for 1.5 years. I also made code reviews for many developers and gave advice about their code. And did feasibility analysis for potential projects.

Git, HTML, XML , AJAX, MacOS, OOP, REST API, Ruby, Ruby on Rails, Unix, CoffeeScript , Agile, CSS, JavaScript, jQuery, Linux, Nginx, PostgreSQL, RSpec, SASS, SOAP, Node.js, Bootstrap , TDD , Redis

• Working closely with clients to establish problem specifications and system designs. • Planning, architecting and developing web applications from the ground up. • Conducting feasibility analysis for potential projects and estimating approximate time for development process • Creating system, integration and unit test cases. • Reviewing code written by junior/middle developers, mentoring and giving feedback about their code • Working with webservices, both REST and SOAP, • Writing a wrapper framework for webservices, • Shipping a top-quality and best user experience products despite very complex and undetermined external services, • Co-founding a startup about sport social network with rails back-end api and ionic front-end (it didn't go well because of consumer aspects), • Teacing experience at only Rails course in the country (LKD Turkey Summer Camp)

I expect to work in a place that I can challenge myself and improve. I am working as a Full stack developer but my main speciality is back-end development. I expect to work in a predominantly back-end position. I can do front-end tasks but I expect not to work as the main frontend if a framework like React or Angular involved in the project.

CTO, Solution Architect, Tech Lead

NYC, Bay Area, Kharkiv, Lviv, Kyiv · $10000 · More than 10 years of experience · Advanced/Fluent

Have been a computer geek since before it was cool. Programming for over two decades, these days I do all kinds of engineering: front-end, back-end and even reverse :-) Fluent english, strong leadership and management skills.

Rails, Ruby, Ruby on Rails, Web Development, Algorithms, Automation, CSS3, DevOps, Highload, HTML5, JavaScript, Linux, Python, ReactJS, Test driven development (TDD), AWS, MySQL, Networking, Perl, PostgreSQL, Scala, Clojure, MongoDB, SQL, Agile, Scrum, REST API, Docker, Git, Node.js, TDD, Microservices

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.
