Kacper is an amazing full-stack (React + Node.js) developer to work with. Eye for detail, always helpful with technical documentation, following trends, and suggesting smart solutions. Any team would be lucky to have him. He's not just a great developer, but a positive guy to have around. What impressed me most was his proactive approach, seamless communication, and ability to manage time productively.

My approach
Planning & Strategy
We'll collaborate to map out your app's goals, target audience, and key functionalities. We'll discuss things like app structure, navigation, and content requirements. Then we will agree the estimated time, needed to develop every feature and how you can track the progress.
Development & Progress Update
Once we agree on the plan, I dive into coding. From initial sketches to cleaned and polished code, I keep you updated every step of the way.
Acceptance & Launch
This is where the results are provided. You will get the code and docs, if requested in the planning phase. Then you can launch your product and decide, if you want to collaborate in the future.
