My project experience includes: — Created a subscription service for music courses. — Developed internal components and libraries to simplify testing, restrict access to functionality (like feature flags). — Designed, documented, and developed a REST API with the potential for future isolation into services. — Refactored an existing monolith to facilitate the separate extraction of individual services. — Implemented new standards for documentation formatting, tasks, as well as internal libraries and components. — Implemented a strict type system for objects involved in existing requests to external systems.

Currently working as a consultant. My work experience includes: — Supported and developed new website functionality and an in-house CMS written in PHP 5.6, while refining existing modules. — Re-designed user interface based on provided layouts to improve usability. — Designed and implemented the backend of personal account system using Phalcon 4 framework, followed by re-implementing the same system with Go language for increased performance. — Developed a multi-platform chatbot (Web, Telegram, VK) featuring a multilevel menu structure, later refactored it for optimal efficiency with Slim 4 framework. — Successfully redeemed CMS from PHP 5.6 to a more efficient PHP 7.2.

My project experience includes: — Conducted API refactoring to enhance system performance. — Optimized code efficiency for improved functionality. — Implemented strict typing system for identifiers to reduce potential issues.

My work experience includes: — Developed diverse systems for internal usage as a project contributor. — Led refactoring efforts and split existing services by migrating functionality from monolithic applications into new, independent services and libraries. — Employed unit testing to ensure consistent performance on both pre-existing and new features in keeping with stringent quality control measures. — Enhanced user experience through introducing well-crafted service options tailored to match the ever-changing industry standards while ensuring high-end solutions delivery within established timelines — Designed & implemented an end-to-end loyalty system that streamlined multiple programs thus facilitating a singular backend setup providing seamless synchronization capabilities between them; additionally adopting efficient schema specifications provided ease of transitioning usability among different systems used resulting in satisfactory discharges. — Optimized database queries needed for effective compromise during execution of asynchronous cron tasks. — Successfully onboarded and trained a junior PHP developer for the loyalty program, ensuring knowledge transfer and readiness for my eventual transition off the project.

My work experience includes: — Maintained both CMS and CRM applications utilizing a self-customized PHP engine. — Successfully redeemed the engine by re-writing its systems from PHP 5.5 to a more efficient PHP 7.0. — Designed and implemented an API for mobile applications. — Transcending boundaries, explored integrating microcontrollers into Python3 Apps via COM ports alongside cross-platform GUI programming enabling hardware operations across diverse operating systems viz: Windows & Linux machines. — Developed a Kotlin-based mobile application supporting user registration, authorization as well as QR-code scanning capabilities effectively transmitting aggregated data to servers where users reviewed extensive measurement histories alongside precise outcomes within two weeks. — Expanding my knowledge base within three weeks, I undertook iOS development before implementing corresponding Swift 5.1 apps through SwiftUI functioning similar to Android versions of the app while ensuring utmost efficacy during operation

My project experience includes: — Built a website with two distinct personal cabinets to cater for both client-customers and contractor-clients, as well as an administrative panel utilizing the Flask framework. — Developed and implemented a referral system open to users of all types. — Designed and implemented a RESTful API that maintained full service functionality on mobiles through the use of Swagger documentation. — Created an interactive chatbot which had multi-platform integration including VK, Facebook Messenger and Telegram by way of virtual keyboard interactions.

I developed CMS for websites using PHP, utilizing frameworks such as Laravel and Yii. I also worked with custom-made frameworks. For certain websites, I integrated API from social media platforms such as VK, Facebook, and Telegram. My experience includes working with databases like SQLite, MySQL and PostgreSQL. Furthermore, I created REST APIs for mobile applications' communication. I developed chat-bots for VK, Facebook Messenger and Telegram. In addition to programming tasks, I organized a team consisting of individuals with a diverse set of backgrounds and skill sets. Specifically, such teams comprised designers, front-end and back-end developers, as well as proficient mobile developers.
