Development technologies

Development process:

• Git is used, Git-flow method followed
• secure internal Git repositories
• external repositories: Bitbucket, GitHub
• Git integration with the task setting system
• a system used to control projects loading to several servers
• Docker to emulate project environment on software engineer's work stations
• code-review, code analysis.

PHP with engineering patters applied

• proprietary framework and CMS
• MVC, module-based architecture
• multilingual data, multilingual user interface
• DB versioning, prompt interaction with the DB — we don't use ORM and ActiveRecord
• prompt generation of HTML/XML/JSON — we don't use template enginedata caching; Memcached, Redis, on-disk cache
• automatic intercept of run errors
• custom logging
• mailing control
• integration with Sphinx, morphological search through texts
• payment systems integration
• external services integration
• support of CDN and cloud data storages
• password-free user access
• restoration of deleted user data
• data backup sub-system with external data storage support
• XML Sitemap generation
• schema.org, structured data, snippets and Yandex micro-formats for search engines
• secure hack-proof architecture.

Other frameworks

• WordPress, 1С-Bitrix, Laravel, Lumen, Zend, Slim, F3

Data base — Mysql, PostgreSQL, MS SQL, Redis, MongoDB

• design
• complex queries optimization
• slow query monitoring after project switch to real data
• clusterization

Frontend

• semantic markup, cross-browser compatibility, IE10+
• adaptability, mobile versions, support of high-aspect ratio and high-resolution displays (retina)
• bulma to expedite projects release
• compilation — Gulp
• style sheet preprocessors LESS and SASS, post-processing— PostCSS
• styles and scripts minimization
• use of TypeScript and JavaScript ES6 (ES-2015)
• graphics optimization, use of sprites, SVG and web fonts

Terms of delivery and reliability
