Backend & REST API
Design and development of APIs and web applications in Symfony. Clean architecture, validation, tests and static analysis.
I'm a Backend developer
I build backends and REST APIs in PHP and Symfony, containerize them with Docker, ship them through automated CI/CD pipelines – and bring AI into both development and business workflows. I care about security, readability and simplicity of code.

My name is Lukáš and I've been into computers since I was a kid. I started programming in 2012 – my first languages were Pascal and C++, but I didn't stick with them for long.
Today I develop backends for all kinds of applications, mostly REST APIs. I work primarily in PHP and my framework of choice is Symfony. Over the last five years I've worked mostly as a freelancer – building APIs for internal systems and designing the architecture of the applications I deliver. On the frontend I use React and Tailwind, and I'm an active Linux user and administrator.
I also take care of the whole road to production. I package applications into Docker containers, build CI/CD pipelines that test, analyse and deploy every change automatically, and keep them running reliably on Linux servers.
Lately I've been focusing on AI – integrating large language models into applications, building AI agents, automating business processes and using AI to speed up the whole development workflow. I'm also into web application security and want to grow further towards penetration testing and vulnerability analysis.
Mostly freelance work – from simple websites to custom internal systems, AI-driven tools and my own projects.
Working on my own project Lorderon – an online game server with its own web portal, user panel, rankings and multilingual news. The closed beta has been live since August 2026.
Custom ERP and CRM solutions built for specific problems instead of configuring boxed software. Smaller contracts for internal tools where I use AI heavily to automate business processes.
Administration system for Metin2 private game servers – a Laravel web application with a server dashboard, custom monitoring, ban system and log management.
Small websites, presentation pages, contact forms, one-off jobs and modifications of existing websites.
Got deeper into web development, learned PHP, built my own projects and started exploring web security.
Design and development of APIs and web applications in Symfony. Clean architecture, validation, tests and static analysis.
Integrating LLMs into applications, building AI agents and automating business processes. I also bring AI into the development workflow – from code generation to reviews and testing.
Containerizing applications with Docker and Docker Compose and automated CI/CD pipelines that run tests, static analysis and deployments on every push.
Administration and monitoring of Linux servers, automation with scripts and a strong focus on security.
Self-assessment – the longer the bar, the more time I've spent with the technology.
