Responsibilities: work on the company's internal systems (management interfaces, student interfaces, internal infrastructure); 50/50 managing and writing code. Team management is more or less standard: planning, task analysis, code review, group calls for synchronization, tete-a-tete calls for status tracking and experience sharing.PHP, MariaDB, PostgreSQL, MongoDB, Redis in Docker, CI/CD via Gitlab a bit of Zabix for monitoring, log management via ELK. The last two items were being done by devops mostly, I just got the assist.For about two years, we have been dividing the monolith of old PHP versions into services and microservices with REST API, we spread everything there with a thick layer of Swagger and documentation so that nothing is left without attention. In addition, we run tests, mostly Unit Testing. There is a lot of architectural work here, load distribution, planning it, business communication on problems and needs of the company.

Refinement of internal systems and tools, development of new servicesPHP (Slim, Zend), MariaDB, Redis, the code in Github, releases via Jenkins or manually via Capistrano (hello, Ruby)Speaking of "complex" projects - integration with Google, Yandex, MyTarget, Facebook at the level of collecting the necessary information on advertising companies, integration with AmoCRM for the sales department (+ related difficulties and sales department's wishes fulfillment).Around here, there start conversations that it's time to divide the monolith into something more suitable for company's needs, otherwise it's difficult to convey the features to users, it is difficult to control the load and predict the development of the code base.

I've designed and developed the first iteration of the product throughout a startup for acquaintances. Besides writing code itself, there is a lot of projecting, support of a new team that was put together for the project, the main processes setting up assistance.I wasn't officially employed in the company, we entered into one-time works contracts or writing agreements, but in general there was a wide range of works.In Python, I projected and wrote the first versions of parsers to implement Zapier-type integrations, but only for services without open APIs. Parsing by means of Headless browser on Selenium with minimal human disguise. Backend on Django + PostgreSQL, DRF for implementing the json rest api for Frontend integration (it was written by outsource guys on React) daemon bots ran through Supervisor with Fastapi as an interface to the outside. Bots were working in stateless mode, that is, they did what you tell 'em to and immediately gave the result, so no data storage was provided for them.

Fintech startup (stock analytics): support of existing projects, design and development of new ones.Initially, the project was built in PHP (Yii2). The first prototypes were successful, more load and functionality went on, as a result PHP couldn't handle anymore, we began to build a new Python version (Django bundled with DRF), attached RabbitMQ for communication between services where the usual rest api was not enough. Everything was put into a Postgres cluster deployed in the newly appeared Yandex Cloud.There was a certain amount of mathematics and work with stock analytics, optimization of crude scripts from analysts into more productive versions for the production environment.As a result, everything was smoothly assembled in Yandex Cloud, laid out in Docker containers within its own Gitlab server, deployment was configured, and monitoring.I integrated a lot of brokers in Python (securities trading) through their API (or what was provided instead). These were both simple rest json-like apis and old xml. The most trendy ones gave webstreams. Here's an interesting one: asynchronous stuff in Python via asyncio

Own business no longer held, I returned to the company where I had worked before. All the same pool of works: custom development on Bitrix, refinement of standard components.Several interesting projects in PHP to collect data from a dozen forums on joint procurement. Parsed through headless browsers, pretending to be forum users, otherwise it was impossible to access the content.Revision of the company's marketplace http://www.berito.ru Here it was needed to carefully dock the front on the angular with the data. And since there was a lot of data, and the front was slowing down terribly, we had to solve optimization issues at a fairly low level.I replaced the front-end developer a little, we did complex integration with Yandex maps for a construction company selling new buildings. It was necessary to impose a render of a future urbanized area to a place where there was a quarry on the map (Yandex.maps) And when you click on the building, you get to the map of the house itself, where you can see the layout of apartments, choose the necessary one without leaving the map.

Organization of work of a small development department (3-5 people). Gathered with acquaintances and opened our own business. I was responsible for IT, starting from routers in the office and ending with decomposition of technical tasks. I worked on mostly custom development of landing pages, more or less complex builders for advertising agencies.Managerial experience, ambitious plans for the development of "innovative" products in the field of entertainment (augmented reality projects, interactive versions of paper books, the development of our own fantastic franchise).Around the same time, I wrote my first and only so far fantasy novel.

Custom-made development on Bitrix, mainly online stores, information portals of companies. It was my responsibility to finish the standard components to the required state. A great team, together we reassembled the "inner kitchen" of the development in the company.Complex integrations with 1C, attempts to keep Bitrix up with the angular of the first version, training colleagues to work with "modern" technologies like git :)
