Full-stack developer and teacher, based in Lublin.
I'm a full-stack developer based in Lublin, Poland, specializing in building modern web applications with Laravel and Vue. Since 2021, I've been crafting efficient, scalable software that addresses real-world challenges.
My approach combines technical expertise with a deep understanding of user needs. I'm committed to writing clean, maintainable code and designing solutions that deliver measurable impact. I embrace new technologies when they add genuine value to a project.
Beyond development, I teach programming at a technical high school, focusing on web application development. This experience has refined my ability to communicate complex concepts clearly - a skill that proves invaluable in both mentoring and team collaboration.
I keep expanding my skill set. Right now I am learning Java and React, and exploring Flutter, Node.js and Python. I care about clean interfaces, thoughtful UX and modern design.
What I do
Three areas I work in every week, with the tools I reach for.
Backend
REST APIs, business logic, queues, integrations and database performance in Laravel.
Frontend
Single-page apps with typed components, real-time updates and accessible UI.
Teaching and tooling
Web development classes, exam preparation platforms and small tools that remove manual work.
Experience
2026 - present
Freelance Full-Stack Developer
Own business, Michał Ziółek JJW
I build web applications for clients on my own account, most of them under NDA. I take a project from scoping to deployment: Laravel backends, Vue and Nuxt frontends, REST APIs, integrations with external services and Docker infrastructure on a VPS. Alongside client work I run my own products, including MZ DevClass and the Markdown to PDF converter.
2024 - 2026
Full-Stack Developer
appwise | software house
I worked on a large-scale, enterprise-grade backend system built with Laravel for the TSL (transport, shipping, and logistics) industry. My focus was on implementing complex business logic, optimizing backend performance and PostgreSQL queries, and designing and documenting REST APIs. I also delivered integrations with telematics systems and external services, working with queues, Docker (Laravel Sail), and monitoring/debugging tools. In the final phase I was the lead and only developer on the project, also responsible for the Nuxt frontend.
