About Mikołaj
I’m a full-stack developer specializing in JavaScript/TypeScript with various frameworks, including React, Vue, Nuxt, and Next.js for frontend development. On the backend, I work with Node.js and Python (Flask), and I particularly enjoy Laravel for PHP-based projects. I also have experience with AI integration, so if you have an idea that could benefit from AI, I’d be happy to help bring it to life.
As a generalist developer, I’m not tied to any single framework—I adapt quickly and choose the best tools for the job, even if it means learning something new. I love building impactful solutions and prioritize long-term collaborations, ensuring high-quality work that keeps clients satisfied.
If you have an interesting project, feel free to reach out—I’m open to flexible pricing and excited to discuss how I can contribute!
