    I'm CTO on a creative vacation, I always love coding and looking for some opportunities in small and medium projects. I've been working with PHP for more than 10 years and with Symfony for 6+ years since v2.0-alpha. I built or participated in 50+ startups and projects. Also, I've been working as a product manager for the last 5 years, therefore I always catch a balance between business goals, features, tech debts, and refactoring. I can help you with: - writing code according to Symfony's best-practices with proper dividing logic to services, listeners, repositories, etc - creating SPAs with React/Redux and sagas - tunning up performance by adding queues for long-hanging code (RabbitMQ), cache (Redis), speeding up SQL and NoSQL queries - creating APIs (REST, SOAP, JSON-LD, GraphQL) with Oauth, JWT, and other auth mechanisms - integrating third-party APIs like --- payment gateways (Paypal, Stripe, Xsolla, Yandex.Kassa, Robokassa), --- email senders (Mailchimp, Mandrillapp, Sendgrid, Gmail), --- sms notifications (Twilio and any local ones) --- iOS and Android pushes, --- CRMs (Redtail, Salesforce, Hubspot), --- Banks APIs (TD Ameritrade, Pershing), --- maps (Google, Yandex, Maps.me). - creating complex role management systems and ACLs - building admin panels (custom Sonata and EasyAdmin) - upgrading a legacy project from PHP5 to PHP7.4, from Symfony 2.x to 4.4 (long-term support) or even to v5.1 including Symfony Flex - designing the architecture of code and databases (Postgres, Mysql, MariaDB, Mongo) - refactoring existing complex business logic to decoupled services and classes according to the best programming patterns of GOF and SOLID - writing some unit, functional or integrational tests with PHPUnit, Symfony WebTests, and Behat - converting code base to Symfony code-style with php-cs and php-cs-fixer - analyzing security vulnerabilities - automating deployment - setting up full CI/CD via Jenkins, gitlab, travis-ci, circle-ci, drone.io, and others - dockerizing the project

At A Glance: Erlang

There are hundreds of different programming languages that have been developed throughout the years, with each language focusing on and solving different problems, challenges, and difficulties in the world of programming and computer science. One available language you have access to is Erlang, a general purpose programming language that has been supported since its release in 1986 and is now open-source. Erlang’s claim to fame in the crowded programming world is its suitability for building always-available real-time systems that are massively scalable. Those values specifically appeal to businesses in the telecom, banking, eCommerce, and instant messaging fields.

Erlang specialists are skilled in the intricacies of the Erlang programming language, and as such are capable of providing you and your business with a variety of valuable services. If you are looking to develop programs and applications from scratch, an Erlang specialist can help guide you through the process and benefits of using the Erlang language. Erlang specialists can also direct their knowledge and experience toward modifying, updating, or debugging current applications or software your company may be using. They can even tailor new interfaces to leverage features from other programming languages. By nature, freelance Erlang specialists and programmers are typically available to look at and work on smaller sections of code in a piecemeal fashion, when needed, thus providing a cost-effective way to manage Erlang-written software without investing too much valuable time and resources. And as with any Upwork freelancer, you gain the flexibility of partnering with talent based anywhere in the world.
