Arthur Melikyan

Objective

Senior PHP/Laravel engineer with 7+ years building AI integrations, fast APIs and high-performance backends for consumer products.

I write clean, secure, efficient code and tune the full stack — Linux, Nginx, Redis — when performance matters.

• Integrated many AI providers (OpenAI, Anthropic, Google Gemini and more) behind one unified interface.
• Built multiple payment integrations with PCI-aware flows.
• Set up and tuned Linux servers with Nginx / Apache, Redis and queue workers.
• Test-first approach and SOLID principles for reliable, maintainable code.
• Comfortable in Agile/Scrum teams (Jira, Trello, ClickUp).

Professional experience

1. Hyperspace.ai — Senior Fullstack Engineer

   Apr. 2024 – Present

   • Lead the AI-integration layer of a generative-AI product — 12+ external models (OpenAI, Anthropic Claude, Google Gemini, Mistral, Midjourney, Leonardo, fal.ai, ElevenLabs, Suno and more) behind one interface, so the rest of the product need not know which model runs.
   • Build and maintain chat and content-generation flows across text, image, audio and voice — streaming responses, plan-based quotas, multi-model selection, and a migration of the old chat schema to a new conversations model.
   • Cut API response times 4–5× through query tuning, code refactoring, smaller payloads, caching and Laravel Octane, and build new API layers for cleaner data flow to web and mobile.
   • Scale SEO for a large-page product (sitemap splitting, feeds, structured data) and keep the platform current with regular PHP/Laravel upgrades and queue tuning.

   Stack: PHP/Laravel, Laravel Octane, Vue, Nuxt, PostgreSQL, Redis, Algolia, Laravel Horizon, WebSockets, CI/CD, PM2, PHPUnit.

   • Built new features and fixed high-impact bugs across a Hypervel stack of 10+ microservices.
   • Fixed payment-flow issues — refunds, webhook retries and idempotency — affecting live transactions.
   • Improved caching and Redis usage, cutting repeated database calls on hot read paths.
