PHP & Java Developer

About Me

Hi! I'm Łukasz, a backend developer with solid experience in PHP (mainly Symfony), and some practice with Laravel and pure PHP.

Over the years, I've built backends for fintech, medical, and e-commerce projects – from complex REST APIs to systems handling thousands of requests daily.

I'm currently deep-diving into the Java + Spring Boot ecosystem, developing my own apps and microservices. I love system architecture design and automating everything possible.

I'm fluent with Docker, databases (MySQL, PostgreSQL), Git, and CI/CD workflows. I enjoy clean code and well-written documentation.

Outside of work, I enjoy running, cycling, creating logic puzzles, and exploring new technologies.

Services

I offer full backend support for web applications. I specialize in PHP-based projects (Symfony, Laravel), but also build new solutions using Java and Spring Boot.

API Development

I design and implement scalable REST APIs and API-first applications – with complete documentation (OpenAPI/Swagger) and thoughtful structure. I follow best practices for security and performance.

Backend Architecture

I help design solid backend foundations – from monolithic architecture to microservices. I choose the right technologies and build communication/integration layers.

System Integrations

I integrate apps with external systems – partner APIs, payment gateways, ERP/CRM systems, marketing tools, and cloud services.

Refactoring & Optimization

I analyze existing code, remove performance bottlenecks, and apply better practices. I improve structure, tests, and documentation, preparing systems for future growth.

MVP Development

I help quickly launch the first version of your product – from needs analysis through backend/API to deployment. Perfect for startups and testing new markets.
