Overview
A middle-level PHP backend engineer focused on building small monolithic web APIs and SQL-backed content sites. The strongest proven skill is SQL-driven repository design and tuned queries, evidenced by Fromix13387/testPhp/app/repositories/ArticleRepo.php which uses window functions and aggregated queries to avoid N+1 patterns. The codebase lacks public evidence of production-grade observability, auth/token lifecycle handling, distributed system patterns or automated tests.

Full-Time
Developed and maintained a B2B real-estate platform for developers and real-estate agencies, including catalog features, mortgage-related tools, CRM integrations, and analytics. Built and extended authorization flows, including Telegram-based login methods and email/password code flows. Migrated analytics workloads from MySQL to ClickHouse to speed up queries and reduce load on the primary database, and optimized SQL by redesigning queries and adding indexes and intermediate tables. Implemented integrations with CRM systems (amoCRM, Bitrix24, Zoho CRM) including data sync, error handling, and background tasks.

Middle Backend Developer
Confidence: Medium API Engineer
A middle-level PHP backend engineer focused on building small monolithic web APIs and SQL-backed content sites. The strongest proven skill is SQL-driven repository design and tuned queries, evidenced by Fromix13387/testPhp/app/repositories/ArticleRepo.php which uses window functions and aggregated queries to avoid N+1 patterns. The codebase lacks public evidence of production-grade observability, auth/token lifecycle handling, distributed system patterns or automated tests.
API Design
4/10
How well APIs are designed
Basic API routing and request handling with pagination/sorting support are present, but there is no versioning, idempotency keys, or a consistent error contract.
Data Layer & Database
5/10
Working with databases
Clear repository layer with hand-written SQL, prepared statements and a migrations runner show solid data-layer fundamentals; lacks visible transaction handling, isolation-level considerations and a multi-step migration history.
Scalability & Performance
4/10
Handling load and speed
Some query-level performance work (window functions to avoid N+1 and aggregated similar-article query) but no caching, queueing or measured load optimizations.
System Architecture
4/10
Overall system structure
Reasonable module boundaries (controllers, services, repositories, DI container and router) indicating deliberate structure; the project is a small monolith with no inter-service contracts or service decomposition trade-offs.
Security & Auth
3/10
Protecting data and access
Prepared statements reduce SQL injection risk and foreign keys enforce referential integrity, but there is no visible authentication, token lifecycle, input validation framework or secrets handling patterns.
Reliability & Observability
2/10
Stability and monitoring
Minimal reliability and observability patterns; migration logs and DI cycle detection exist but there are no retries/backoff, structured logging, metrics, or graceful shutdown logic visible.

Recommendations
- Develop content-driven web backends and e-commerce MVPs that need careful SQL and repository design.
- Extend and harden the existing DI and routing foundation to add authentication, input validation and structured logging.
- Implement migration chains with transactional migrations and add tests for repositories and services.
- Add caching or background job queues for high-read endpoints and measured performance testing for heavy queries.
Repositories

Junior Frontend Developer
Confidence: Medium UI Engineer
Frontend UI engineer (junior) focusing on building styled, component-driven web interfaces with React and Vue. The strongest proven skill is crafting consistent CSS/SCSS component styles and responsive layouts as seen in Header.module.scss and Basket.module.scss. There is little evidence of testing, advanced state management, performance instrumentation, or accessibility engineering in public code.
UI Component Architecture
2/10
How interface parts are built
Basic component structure with simple Vue components and modular CSS, but no evidence of deliberate composition patterns, design system, or advanced component APIs.
Evidence
practicByVue/src/components/Header.vue: simple header component using props and click handlers
practicByVue/src/App.vue: parent component composing Header, Home, Calc, Quote
sushi-site/src/assets/Components/Header/Header.module.scss: component-scoped styles and structure
Responsive & Cross-browser
3/10
Works on all screens and browsers
Responsive layouts implemented with media queries and grid; reasonable attention to mobile bottom nav and sticky catalog, but no progressive enhancement, RTL or feature-detection strategies.
Evidence
sushi-site/src/assets/Pages/Menu/Menu.module.css: media queries adjusting grid from 3 to 2 to 1 columns
sushi-site/src/assets/Components/Header/Header.module.scss: @media rules and mobile adjustments
sushi-site/src/assets/Components/Header/Header.module.css: .tel_nav fixed bottom navigation for mobile
Performance Optimization
1/10
Speed of the interface
Almost no measurable or explicit performance work; uses modern tooling (Vite) but no code-splitting, lazy loading, bundle analysis, or virtualization.
Evidence
sushi-site/vite.config.js: Vite config with React plugin present
sushi-site/package.json: uses vite build and dev scripts (modern bundler usage)
Accessibility & Semantics
1/10
Usable for everyone
Minimal accessibility focus; interactive elements are simple but there are raw clickable divs and no ARIA, focus-management, or automated a11y checks visible.
Evidence
practicByVue/src/components/Header.vue: clickable divs used for navigation rather than semantic buttons/links
practicByVue/src/pages/Calc.vue: inputs and interactive controls without explicit keyboard/focus handling
State Management & Data Flow
1/10
Managing data in the app
State is local and simple (v-model, basic fetch); no evidence of server-state discipline, request cancellation, optimistic updates, or state machines.
Evidence
practicByVue/src/pages/Quote.vue: simple fetch call to external API with no cancellation or error handling
sushi-site/src/assets/Hooks/useOrder.js: import store from "store" (indicates simple local persistence but no full state workflow shown)
practicByVue/src/App.vue: local page state used to switch views
UX & Visual Polish
3/10
Look and feel quality
Decent visual polish and consistent styling across pages with SCSS/CSS Modules, clear UI patterns and mobile-friendly elements, but UX edge states and skeletons are largely absent.
Evidence
sushi-site/src/assets/Pages/Basket/Basket.module.scss: detailed styling for basket, forms and actions
sushi-site/src/assets/Components/Header/Header.module.css: cohesive header and footer styling demonstrating visual consistency
sushi-site/src/assets/Pages/Menu/Menu.module.css: product card grid and sticky catalog styling

Recommendations
- Assign to build or iterate on small to medium e-commerce frontends and marketing pages where polished UI and CSS skills are primary requirements.
- Have the developer implement component-driven UI work using a shared design token system and migrate duplicated styles into reusable components.
- Pair the developer with a senior engineer to add automated tests, introduce state management patterns for server state, and teach request cancellation and optimistic update flows.
- Task with accessibility improvements and semantic refactors (replace clickable divs with buttons/links, add keyboard and ARIA behavior)
