Customizations, Full Website Builds, Troubleshooting and Fixes
I am working as a web developer for over 20 years. I provide end-to-end solutions from understanding the issues, and specifying them, to designing wireframes (but not including webdesign) and finally building ready-to-use responsive business or e-commerce websites. For the past 10 years, I've specialized in custom WordPress development, working extensively with Elementor, Crocoblock, ACF, and now focusing on Bricks. I also have a strong background in design, UX/UI, and always prioritize technical SEO. My approach is to use minimal plugins, ensuring that every project precisely reflects both the web design and the business logic, delivering clean, efficient, and tailored solutions. Feel free to get in touch. Ask for more references and let's discuss your business needs or imaginations.

Can't say enough good things about Laszlo! We hired him to help us finish building out a high risk website for one of our clients. Laszlo was always on top of everything and communication was top notch. The project kept getting delayed but he was incredibly patient working with us and ensuring we were satisfied every step of the way. Will definitely be coming back to him for our next project!

Laszlo was terrific in figuring out how to fix a booking issue on a client's website. He updated a plugin that had expired and created some coding to resolve an issue regarding how many bookings appear on a website and how many bookings customers can sign up for. I highly recommend working with him.

Im new to this community and joined because of an issue with WPML. Laszlo tried to understand what was going on and welcomed me into the community explaining how things work. Initially it was a troubleshooting issue, but then I managed to fix the issue and turned into specific deliverables. Laszlo knows his way around WPML and delivered everything as expected. 10/10 will work with him again in the future!

YouTube videos suddenly stopped displaying on my WordPress site using Chrome, but they did display on Firefox. Plus, photos weren't appearing in a certain area of the page where they should. Laszlo did research and determined the problem lay outside of my WP app after exhausting and trying different techniques. Laszlo's communication skills, both written and orally, are impeccable. His analytical and logic skills are exceptionally thorough and organized, along with a deep capacity for figuring stuff out. What a gem of a resource: smart, thorough, organized, competent, professional, quick, flexible, easy to chat with, etc. Many thanks Laszlo, I truly appreciate you!

Perfect, nothing to say! I just thought the code would be more complex for the price.
