About Denys
FullStack PHP(Laravel/Symfony) JS(Vue/React) API Expert
Kharkiv, Ukraine - 1:16 am local time
I’ve delivered complex systems in FinTech, ERP, government, SaaS, and geospatial domains. I care about clear code, Domain‑Driven Design, and systems that can evolve without breaking.
What I’m best at
• Laravel & Symfony: enterprise apps, custom packages, REST APIs
• API Platform: REST/GraphQL, JSON‑LD, OpenAPI/Swagger
• Architecture: DDD, Hexagonal, CQRS, Event‑driven systems, RabbitMQ for async messaging
• Real‑time: WebSockets, Mercure
• Databases: MySQL, ClickHouse, PostgreSQL, PostGIS, FTS, pgRouting, Elasticsearch
• Observability: Kibana (log analysis), Grafana (metrics/dashboards)
• Frontend: Vue, Nuxt, React, Next.js
• Infrastructure: Docker, Linux, NGINX/Apache, Redis
• AI Coding Agent: daily use of GPT/Codex & Claude Code for faster scaffolding, refactoring, test generation, and cleaner code
How I help clients
• Build or modernize Laravel/Symfony applications
• Design secure, versioned APIs for web/mobile clients
• Add real‑time features and messaging
• Optimize performance: queries, indexing, caching, Elasticsearch, async processing with RabbitMQ
• Deliver geospatial systems with PostGIS and OSM
• Stabilize and scale existing codebases
• Set up Kibana + Grafana monitoring for logs, metrics, and system health
• Deliver cleaner, better‑documented code faster by leveraging AI Coding Agents (GPT/Codex, Claude Code) in my daily workflow
If you need a senior engineer who can own the backend architecture, deliver clean code, and communicate clearly, let’s talk.
