Moin, ich bin Nikita – leidenschaftlicher Senior Frontend Developer mit über 16 Jahren Erfahrung in der Webentwicklung.
Ich entwickle moderne, performante und skalierbare Web-Applikationen mit Fokus auf TypeScript, React, Next.js, Astro und Vite.

Ursprünglich startete ich mit HTML, CSS, PHP, MySQL, JavaScript und jQuery, habe mich aber auf die Entwicklung von modularen Frontend-Architekturen, SSR/SSG-Lösungen und High-Performance-Interfaces spezialisiert.
Meine Projekte zeichnen sich durch sauberen Code, hohe Wiederverwendbarkeit und optimierte Performance aus – sowohl im Frontend als auch in der Anbindung komplexer REST-APIs.

Ich kombiniere technisches Know-how mit einem klaren Gespür für UI/UX-Design. Tools wie Figma, TailwindCSS, shadcn/ui, Mantine oder MaterialUI gehören für mich zum Standard-Stack.

Neben meiner Projektarbeit engagiere ich mich aktiv in der Open-Source-Community.
Ich entwickle eigene NPM-Packages, Framework-Erweiterungen und Tools für React und Astro, die weltweit genutzt werden und tausende wöchentliche Downloads erzielen.

Ich habe Erfahrung in der Zusammenarbeit mit Startups, Agenturen und Enterprise-Kunden und setze dabei auf agile Prozesse, CI/CD-Pipelines und DevOps-Workflows.

Primary Tech Stack:
TypeScript, JavaScript (ES6+), React, Next.js, Astro, Vite, NPM, Git, React-Router, React-Query, React-Hook-Form, Jotai, Formik, TailwindCSS, Sass/SCSS, shadcn/ui, Mantine, MaterialUI, REST-APIs, Axios, i18n/i18next, CI/CD, Node.js, Figma, Open Source.
