Projects that demonstrate what I inspect in an audit: code, data, servers, and operations

Problem. The engine needed more than a download page: it required clear product information and documented legal status so businesses and individual users could evaluate it.

• What I did. Prepared the product for release with a public overview, release archive, installation and operations documentation, and structured search data. It was entered in the Russian software registry and registered as a computer program with Rospatent.
• Result. The product has verified legal status through a Russian software registry entry and a Rospatent certificate, clear support channels, and a deployment process independent of a single local environment.

Business value: I can prepare a product so businesses can deploy it with clear technical and legal documentation.

Problem. The learning platform needed a controlled process for assignments, access, reviews, and deadlines, plus predictable releases without downtime or undocumented manual deployment.

• What I did. Designed the domain model and built the complete stack: PostgreSQL with versioned Flyway migrations, the application and database in Docker containers, and a CI/CD pipeline with automated tests, OpenSSF Scorecard security checks, and automated production deployment.
• Result. A service running in Docker containers with reproducible releases and change control, automated pass/fail tests for learning scenarios, and a registered Lomt LMS trademark.

Business value: This brings together every layer I inspect in other systems — architecture, data, migrations, tests, deployment, and operations — in one project from inception to production.

Problem. The news stream must be collected from many sources, stored reliably, and published without downtime, while sharing the same constrained resources as other services.

• What I did. Built a Spring Boot service with PostgreSQL and Flyway migrations, a dedicated memory-limited systemd runtime behind HAProxy and Apache, and a reader-facing site with direct links to original sources.
• Result. A continuously operated online publication listed in the Roskomnadzor media registry runs on one VPS alongside other services, with controlled collection, storage, and publication.

Business value: This demonstrates operational discipline: running a service continuously without dedicated infrastructure for every project.

Problem. A large free-font collection had to be migrated from legacy PHP to a modern architecture without losing the archive, search, previews, downloads, or search visibility.

• What I did. Split the project into a Java backend with a version 1 public API, Spring Boot, PostgreSQL, Flyway, and an OpenAPI contract, plus a public frontend built with Next.js App Router, React, and TypeScript; preserved the font collection, categories, search, preview tool, and SEO layer.
• Result. Shriftik.ru now runs as a modern application: 7,685 fonts are available through a React interface and separate API, the legacy archive has been migrated into a managed data model, and releases are verified in both code and infrastructure.

Business value: I demonstrate how to migrate a live legacy service to a maintainable Java + React stack without product downtime or loss of accumulated content.
