Projects Experience

• Developing MTProto lib for Telegram API, KHS Films

  Sep, 2020 - Dec, 20203 months

  I've made a package which is must work with, perhaps, one of the most confusing interfaces among popular web services, the MTProto protocol. Were developed: a basic wrapper over the protocol, an encoder/decoder of binary messages, a codegen to cover all current methods from the latest api version. The project received wide support from the opensource community, it scored more than 900 stars on github, stats are showing that this repository is cloned and used by more than 60 unique users daily.

• Developing CoAP protocol utilities

  Sep, 2020 - Dec, 20203 months

  Recently, I became interested in the alternatives of MTProto and began to develop my own project for the implementation of the undeservedly unknown CoAP protocol. At this moment, there is an implementation of the tcp version of the protocol, which i'm developing purely for academic interests. I am also developing a gRPC adaptation for this protocol: created a generation of two-way simple rpc server based on protofile, as well as a small proxy server that converts http requests to coap and vice versa. The project is in the stage of bringing to a stable functionality.

• ERP system for pub, Xelaj Software

  - Present

  It was necessary to develop an easily portable service for kitchen and bar which can operate without internet, with a simple and intuitive interface, and a flexible administration system. As result, this task was solved, and the project resulted in a simplified analogue of Odoo. The service was written in python, packaged in a docker container, and works great as intended to this day in a small staff room of the bar running on raspberry pi. The database works on sqlite, the server was written using flask.

• Creating full-feature IAM system, KHS Films

  - Present

  Another task: our team had a task to create a full-fledged IAM system for creating a subscription products based on a payment service with a poor api and several complex services (kajabi platform, telegram chat, private discord server, personal webinar platform). As a result, we made a complex service, which, based on several payment systems (both cloudpayments and stripe payment systems, and subscription-sale services: patreon, twitch subscriptions, youtube sponsorship) which allows flexible configuration of available resources for each member (f.e. for member who has tier 1 twitch subscription or youtube sposor, he can join to a telegram chat in read-only mode and part of text channels in discord server, but for custom patreon subscription for $10, he can get access to kajabi courses, full access to discord server and telegram chat).

• Libraries and wrappers for APIs, KHS Films

  - Present

  For personal use, I had to make wrappers for different api: cloudpayments, amocrm, vk, timepad, etc. All results are opensourced, available on github, and can be used for any purpose. link to github. In addition, I participate in the development of the open ui framework bubbletea, as well as the framework for creating synthesizers and bleep sequencers.

• Amocrm to Google Spreadsheets Synchronizer, Xelaj Software

  - Present

  The task was to synchronize data between Amocrm and Google Spreadsheets, sheets were using as database-likely platform for writing various sheet scripts. Since there are no workable wrappers for the Amocrm API on golang, I had to write manually, in parallel describe OpenAPI specification. There was also a problem of finding updates from the sheets and correctly transferring them back to the Amo. As the result, the following things were created: 1) a micro-wrapper for base google API library, which allows you to work with tables as with full-fledged databases (including sql-like stuff), 2) a wrapper for AmoCRM, which allows you to work with their api, 3) a library for converting golang objects into a tabular format (using matrix utility lib), 4) a package for working with updates in tables, with the mechanics of notifications similar to longpoll. Three projects of them are open and available on gitlab. Also, the entire service was packaged in a nice tiny docker container, wrapped with metrics for prometheus, and working well for today.
