Specialization

Maciej is a Full Stack Developer and a Regular Java Developer at Hicron Software. He builds web applications using both frontend and backend technologies. His work covers several business domains including Insurance, Automotive, and PropTech. He also works on modernization projects.

Maciej works mainly with Angular, React, and Java. These remain his strongest areas. For personal backend projects he prefers Node.js.

His approach stays technology-agnostic. He analyzes the problem first, then selects the technology that fits it best. He keeps an open mind toward new stacks rather than committing to a single language. He is also exploring how AI can be applied across the software development lifecycle, with a focus on areas such as workflow automation, code quality improvement, test generation, and delivery efficiency.
