Daniel Lungu

I’m a medior backend developer with 3.5+ years of experience in PHP, mainly in Nette and Laravel, with hands-on exposure to Symfony. I enjoy building reliable web applications and REST APIs end-to-end — from solution design and implementation to integrations, refactoring, and long-term maintenance. My core focus is PHP backend development, and I want to keep deepening my expertise in modern PHP ecosystems, architecture, performance, and clean, maintainable code.

Alongside PHP, I actively work with AI and automation. I lead an E2E Playwright testing initiative and built an internal AI chatbot in Python using LlamaIndex (RAG, embeddings). I use AI tools (e.g., ChatGPT, Cursor, Copilot) to speed up repetitive work, explore solution options, and improve code quality — always as a support layer, not a replacement for engineering judgment.

I like taking ownership, mentoring teammates through code reviews and technical guidance, and pushing projects from idea to production. I’m looking for a long-term role where I can grow further as a PHP backend engineer while leveraging AI to deliver faster, smarter, and higher-quality solutions.

Medior PHP backend developer with 3.5+ years of commercial experience. I work mainly with Nette and Laravel, with hands-on exposure to Symfony, and I deliver web applications and REST APIs end-to-end — from solution design and implementation to refactoring, integrations, performance tuning, and long-term maintenance. I’m confident with MySQL (data modeling and query optimization) and I enjoy improving reliability, speed, and code quality.

In my current role I focus strongly on AI and automation. I lead an end-to-end Playwright E2E test automation initiative — including test strategy, architecture, implementation, and ongoing maintenance. I also designed and built an internal AI chatbot in Python using LlamaIndex (RAG, embeddings), and I integrate internal/external APIs to support product workflows.

I use AI tools daily (e.g., ChatGPT, Cursor, Copilot) to speed up routine tasks, explore solution options, and raise quality — always as an assistant, not a replacement for engineering judgment.

Previously, I worked in a digital/agency environment where I focused on PHP backend development, third-party API integrations, refactoring and optimization of existing systems, and close collaboration with clients to translate requirements into practical technical delivery. I also contributed to frontend parts when needed (JS/jQuery/React).

I want to keep growing deeper in modern PHP backend development (architecture, clean code, performance) while leveraging AI and automation to deliver faster and higher-quality solutions.

I have a high-school education in Information Technology, and I continuously extend my skills primarily through professional practice and ongoing self-education in PHP backend development and AI/automation.
