Taking a break from commercial work while building personal projects and experimenting with application development, infrastructure, and AI-assisted workflows.

• Building AI-assisted applications for the Meshtastic ecosystem: online mapping and monitoring tools, plus a prototype desktop GUI client.
• Experimenting with AI-assisted tooling for personal infrastructure, including amdgputop-web and HDD utilities for a home lab server.
• Restructuring personal self-hosted infrastructure around Traefik, with experiments involving forward authentication through Authelia and request protection through Anubis.

• Developed and maintained the B2Core backend and admin panel using PHP/Laravel.
• Implemented and tested fiat and cryptocurrency payment-system and KYC integrations end to end in PHP, including IDWise, PaymentAsia, Paymid, FairPay, Ramp, Ozow, and others. The B2Core documentation lists the currently supported payment systems.
• Contributed to migrating existing payment integrations from a PHP monolith into Payment Systems Service, a separate Go service, and to implementing new integrations including LuqaPay and several others.
• Contributed to the integration and maintenance of the in-house B2BInPay payment system across PHP and Go services.

Backend development across multiple Drupal 8 projects for international consumer brands and a premium imaging and optics manufacturer.

• Established Drupal site foundations and developed custom modules for content import and synchronization, CDN content management, data processing, and external-service integrations.
• Maintained and improved community Drupal modules, contributing reusable fixes upstream when applicable.
• Participated in client meetings as a development-team representative, discussing implementation matters with client stakeholders.
• Supported frontend developers by providing the required backend capabilities and advising on development tooling and Linux usage.

Developed and maintained the company’s central back-office platform for managing, enriching, and synchronizing travel inventory and reference data across its B2B and B2C products. The platform processed data from multiple external sources and provided internal teams with tools to review, correct, reconcile, and synchronize hotel and pricing data, transport and ticketing information, service providers, and geographic reference data.

• Worked as the senior developer responsible for the platform’s ongoing maintenance, new features, and improvements, alongside another backend developer and several developers contributing data-import and processing integrations.
• Reviewed code for the core project and integrations contributed by the adjacent team.
• Participated in evaluating test assignments from developer candidates.
• Helped migrate legacy code from Symfony 2.7 to Symfony 4+.
• Set up a test Docker Swarm environment for an in-house experiment with containerized microservices handling external-system integrations.
• Contributed to other internal and public-facing projects when needed.

Historical public projects:

• Tank Biathlon festival — developed backend functionality for dynamic ticket booking and sales, integrated a payment system, and prepared deployment configuration.
• Hotelbook Forum — developed backend functionality, integrated a payment system, and prepared deployment configuration.

Worked with a frontend developer to build an interactive e-commerce site for a manufacturer and online retailer of standard and made-to-order uPVC windows.

• Developed the backend of an online configurator for made-to-order uPVC windows and accessories.
• Implemented configuration and validation logic that translated customer-selected dimensions, materials, colors, glazing, window sills, and other options into valid, manufacturable window assemblies.
• Dynamically generated customised window visualisations for an interactive apartment preview.
• Implemented order processing and export to the company’s 1C:Enterprise system.

• Developed a university graduation project that entered production: a tourism-statistics collection and reporting system used by regional municipalities and travel companies.
• Developed OpenCart stores, WordPress projects, and other websites.
• Introduced Git-based source control and structured project deployment practices into the company’s development workflow, and created onboarding documentation.
• Established company-owned server infrastructure used by development and testing environments, the internal CRM, and other internal services, expanding beyond the shared hosting previously used as the company’s only infrastructure.
• Onboarded and mentored interns in the Git and deployment workflows, and reviewed their code.
• Provided architectural guidance to interns working on custom applications that did not use the company’s usual CMS platforms.

Historical examples:

• baza.pomorland.pro
• insant.ru
• meatcom.ru
• arhivazhno.ru — architecture and design only.
