About Nikita

Small and medium-sized businesses face the same challenges: The demands on digital processes are increasing – but internally, outdated systems, media breaks, and manual processes often hinder the daily work. This costs time, money, and nerves.

What I often encounter in practice:
❌ Unconnected or outdated IT systems
❌ Confusing, difficult-to-use software
❌ High manual effort for routine tasks
❌ Media breaks and duplicate work

Technology should make everyday life easier – not more complicated.

This is exactly where I support you.
I am a freelance software developer with over six years of experience in full-stack development. My focus is on modern web technologies and scalable cloud infrastructure. I support small and medium-sized businesses in digitizing their processes through practical, tailor-made software – not standard solutions, but fitting applications.

What sets me apart: I speak my clients' language – and ensure that IT projects are implemented understandably, clearly, and without detours.

This is how the collaboration works:

1. Before the project:
• Free initial consultation: We look together at what's not working
• Free second consultation: I will present you with a concrete solution idea and an offer

2. During the project:
• Analysis: What are your goals? Where can we specifically start?
• Planning: Time, resources, and implementation will be coordinated together
• Development: I will implement the solution precisely
• Testing & Refinement: Check quality, optimize details
• Handover: The application goes live – with documentation if desired

The result:
âś… Less effort & errors
âś… Clearly structured processes
âś… Automation with real benefit
✅ Less paper – more focus on the core business
âś… Solutions that grow with you

My goal: Digitization that relieves the burden – understandable, pragmatic, and suitable for everyday use.

We are extremely satisfied with Nikita Petrich's work as a freelance developer! He significantly supported our AI toy project, implementing a clear, secure, and scalable solution. Nikita developed a Next.js app for easy toy setup, as well as a Next.js Progressive Web Application (PWA) for the dashboard, through which parents can track, filter, and analyze their children's play sessions. For the implementation, he used state-of-the-art technologies, including React, Next.js 15, Tailwind CSS, shadcn, Supabase, Docker, as well as CI/CD pipelines and unit tests to ensure the quality, security, and reliability of the applications. We particularly appreciate Nikita's professionalism, his technical expertise, and his thoughtful approach – we would work with him again anytime and can recommend him without reservation.

    Während meiner Ausbildung zum Fachinformatiker für Anwendungsentwicklung konnte ich umfangreiche Kenntnisse in Softwareentwicklung, Datenbanken und Webtechnologien erwerben. Ich hatte die Gelegenheit, meine Programmierfähigkeiten in verschiedenen Programmiersprachen zu vertiefen und zu lernen, wie man Software in bestehende Systeme integriert. Ein weiterer Schwerpunkt lag auf agilen Entwicklungsmethoden und der praktischen Projektumsetzung. Neben rechtlichen Grundlagen und wirtschaftlichen Aspekten entwickelte ich auch umfassende Projektmanagementfähigkeiten. Durch die praktische Arbeit und die enge Zusammenarbeit mit verschiedenen Abteilungen konnte ich lernen, wie man Projekte effizient steuert und umsetzt. Nach drei Jahren habe ich nun die Fähigkeit, Softwareprojekte eigenverantwortlich zu planen und umzusetzen, um maßgeschneiderte Lösungen für komplexe Anforderungen zu schaffen.
