Arthur Melikyan

PHP / Laravel Fullstack Developer

Objective

Highly motivated PHP/Laravel fullstack developer with 7+ years of experience seeking challenging roles where I can contribute to innovative projects.

I focus on building high-performing, secure applications by writing well-structured, efficient code, and I stay close to the metal — Linux, Nginx, Redis — when performance demands it.

High-performing, secure applications written in well-structured, efficient code.
Hands-on experience with multiple payment-system integrations and PCI-conscious flows.
Server provisioning and tuning on Linux with Nginx / Apache, Redis and queue workers.
Test-first mindset and SOLID principles for dependable, maintainable code.
Comfortable in Agile/Scrum teams using Jira, Trello and ClickUp.

Professional experience

- Leading the AI integration layer of a generative-AI consumer product — integrated more than a dozen external models (OpenAI, Anthropic Claude, Google Gemini, Mistral, Midjourney, Leonardo, fal.ai, ElevenLabs, Suno and more) behind a uniform interface so the rest of the product does not need to care which model is doing the work.
- Shipping and maintaining the chat and content-generation flows across text, image, audio and voice models — streaming responses, plan-based quotas, multi-model selection and a migration of the legacy chat schema into a new conversations model.
- Introducing fresh API layers across the backend to make the data flow leaner and the app feel faster on both web and mobile.
- Engineering SEO at scale for a high-page-count product — sitemap splitting, feeds and structured-data enrichment.
- Keeping the platform on current versions — recurring PHP and Laravel upgrades, dependency hygiene and queue tuning that quietly moves forward.
- Two-plus years of continuous activity: a few thousand commits and a few hundred merged pull requests across the organisation.
