Two products of my own, taken from concept to production and running live.

phpukraine.com — job platform and knowledge base for PHP developers.

PHP 8.4, Laravel 13, PostgreSQL, Livewire, Filament, Pest, PHPStan, Docker, FrankenPHP.

• →Modular monolith split into nine bounded contexts with Domain, Application and Infrastructure layers; the domain layer carries no framework dependency and the boundary is enforced by architecture tests.
• →Hourly aggregation from three job boards behind a single source port, a rules-based classifier for framework, level, city, format and salary, and cross-board deduplication by fingerprint.
• →PostgreSQL beyond plain CRUD: jsonb with GIN indexes, a generated tsvector column for full-text search, transactional row locking for queue leasing.
• →321 Pest tests across unit, feature and architecture layers, plus Larastan level 8 with zero errors; both gate every deploy.

Archemap (archemap.com) — assessment SaaS with AI-generated reports.

PHP 8.4, Laravel 12, MySQL, Redis, Filament, Livewire, Docker, GitHub Actions.

• →Extracted the assessment engine into a standalone Composer package with storage-agnostic contracts and pluggable scoring strategies.
• →Provider-agnostic layer over language models with Anthropic and OpenAI implementations and a fallback decorator that switches providers on failure.
• →CI/CD on GitHub Actions with separate staging and production pipelines and an approval gate before production.
• →Payments, three locales, and a funnel instrumented end to end from first visit to purchase.
