Looking for Go work in cohesive, smart team with good vision and streamlined development process, preferably not remote. Programming languages enthusiast. Love tools that improve productivity. Strives for short and more correct code. Functional programming, domain driven design and TDD are great ideas. Vim and Linux are awesome. Integration testing, internal tooling and deployment automation should be prioritized. 2006 - 2010 - several small-ish perl, python and php projects. 2010 - 2016 - multiple small to medium sized projects, including microservices. 2017 - now - several microservices based Golang projects: fintech, remote monitoring, B2B sales insights

Git, Linux, Docker, PostgreSQL, REST API, MySQL, Microservices, JSON, Python, gRPC, Kubernetes, NoSQL, Rust, Distributed systems, Golang/Go, F#

Solo developed distributed backend for Flash/AMF rpg-style game. Built successful PoC with streaming time series data, 10K rps stable, 200K rps peak.

I'd prefer working on a product, where tangible improvements can be made and individual contributions matter. Good, stable CI/CD and development process, with focus on continuously improving and streamlining tooling. Not interested in working with betting, casual gaming or blockchain.

Data Scientist

Dnipro · $2500 · 5 years of experience · Upper Intermediate

Data Scientist with 5 years of practice in various DS fields: from finance sector to marketing and advertise sphere. I've applied ML for marketing goals in case of selection correct auditory for advertise campaigns - mails, calls, special offers (SAS tool, model types - random forest, logistic regression), also optimized chat-bot answers by n-gram detection (set up auto responses for most frequent ones), used automated topic splitting for text (LDA algorithm). My experience includes data pipeline creation, integration and support. I took part in such tasks/projects which realized on R/Python: - automation of report generation (knitr, Rmarkdown); - generation of insights using math models for advertise campaigns (statistics, R, Python) - set up part of process for automated segments creation (R) - detection of devices which belong to one person. Applied data extraction and processing for different formats: csv, json, html, unstructured text Programming languages: R, Python, SQL Tech tools: Hadoop(data collection), Docker/kubernetes, Git, apache kafka Algorithms: linear/logistic regression, decision trees, random forest, xgboost, text mining, LDA Libraries: caret, gbm, pandas, data.table, tm, slam, sklearn, numpy, xgboost etc. Visualization tools: ggplot2, RMarkdown (for reports) Fundamental knowledge: mathematics, statistics Most amount of work for me is Classical DS, in case of Deep Learning needed - that's absolutely possible but requires more time.

R (language), Mathematics, Statistics, Git, Python, SQL, Hadoop, Machine Learning, pandas, numpy, Matplotlib, Docker, Linux, NLP, Data Mining, Jupyter Notebook, Excel, PostgreSQL, Algorithms, Data Visualisation

Preferences: - flexible work schedule (no matter remote or in office) - challenging tasks - experienced data science team in company - also part-time projects with hourly rate are possible

I am an aerospace engineer with a solid background in software development and data processing. My broad range of interests covers areas of desktop and web applications development, 3D graphics, data science, machine learning, image processing and other. For several years I've been working on development of microwave scattering simulation software. My research in the area of space elevators pushed me towards the development of an open source library for Space Elevator parameters computation using Python and SageMath. Participation in NASA Space Apps Challenge has given me a unique opportunity to develop skills in the area of machine learning, which later allowed me to develop an approach of outlining subgroups of Near-Earth asteroids with high concentration of undiscovered Potentially Hazardous in them. I have initiated a number of open-source projects and contributed code to other projects. For last two years I’ve been working on development of a web application for engineering data processing management using Django, PostgreSQL, ES6 and D3.js. I am a quick learner and motivated to learn new technologies and approaches that will allow me to grow professionally.

PHP-Developer, Developer и не только

Kyiv, Dnipro, Lviv, Harkіv and other city · $3000 · More than 10 years of experience · Pre-Intermediate

- Занимаюсь в основном разработкой, но и не против заниматься интересными для меня задачами/проектами; - Создаю сайты компаний, онлайн-магазины, онлайн кабинеты/личные кабинеты, сервисы типа калькуляторов, онлайн-оплат, API, проекты для блокчейн (конструктор смарт-контрактов, менеджер для инвесторов); - Делал внутренние порталы для компаний; - Создавал полностью ИТ-инфраструктуру для компании на базе стоечных компьютеров, виртуальных машин и функциональной структуры компании (почта, AD, сервера...); - Создавал бренды с нуля, имя, логотип, домен, цвета, дизайн, сайт для двух компаний; - Создал внутренний портал для студентов ИТ-школы; - Преподаю программирование в школе; - Делаю проекты на PHP, Laravel, Drupal, Symphony, Swift, C; - Участвовал в создании хакатона для школьников по работотехнике; - Сейчас изучаю VueJS, Python, NodeJS, React и другое. Интересуют любые интересные проекты, задачи как в сфере ИТ, так и не в сфере ИТ.

Laravel, REST API, Drupal, Bitrix, Symfony, PHP, MySQL, Git, MVC, Linux, Swift, JavaScript, jQuery, OOP, CSS, HTML, AJAX, JSON, CSS3, Apache

Тут сложно выбрать, так все мои работы мне интересны и потому горд за свои работы. Люблю автоматизировать или улучшать эффективность разных процессов. Наверное, больше всех горд за: - Первый свой API; - Первый свой проект по блокчейну; - Портал для компании, которые увеличил продуктивность во много раз; - За сценарий, который сократил работу менеджера с 3 месяцев до нескольких недель; - За создание хакатона по программированию роботов; - За то, что начал преподавать программирование. и много другое.

В новой работе ожидаю интересные проекты и задачи, постоянное совершенствование, старые и новые технологии, адекватных сотрудников, и, желательно, или гибридный график (часть в офисе, часть удаленно), или удаленная работа.
