Hello! I am Taron, a PHP developer with over six years of experience, during which I have worked on high-load projects (over 10000 RPS). Throughout my career, I have worked with frameworks such as Laravel and Symfony, Docker, and CI/CD, as well as deployed projects on Linux using Nginx. I have been involved in performance optimization, data security (encryption, SOLID, DRY, KISS principles), and integration of third-party services such as Facebook API, CloudPayments, Cryptadium, Capitalist, Stripe, Amplitude, Yandex Metrica... I also have experience working with asynchronous queues (Laravel Queues, Redis), analytics on ClickHouse, and real-time interactions via WebSocket and Pub/Sub. In my professional practice, I have actively participated in the development of scalable and stable solutions.

My focus is on creating robust, future-proof systems with clear logging, structured outputs, and minimal dependencies, ensuring every project is transparent, reliable, and built for long-term success. I specialize in advanced Claude AI workflows and multi-model orchestration for executives, investors, and professionals. I have also built a native macOS application in Swift that runs Claude as production infrastructure, including indexed session search, persistent project memory, automated hooks, and scheduled agent orchestration. My focus areas include custom skills and automations that compress multi-step workflows into single commands, MCP and connector integrations into calendar, email, and document storage, scheduled autonomous agents for background research and monitoring, and structured pipelines for high-volume document analysis and investment research.
