FIZNEX is a custom software development agency building AI-powered web apps, mobile apps, SaaS platforms, and blockchain solutions for startups and businesses worldwide. Since 2023, we've delivered 30+ production projects for clients across the US, Europe, and beyond.

We're a full-cycle team. From the first wireframe to launch and ongoing support, we handle design, frontend, backend, cloud deployment, and everything in between —no half-work, no hand-offs.

What we do:

Web & Web App Development — fast, secure, SEO-ready sites, dashboards, and CRMs built with React, Next.js, Node.js, and NestJS

Mobile App Development — native-feeling iOS & Android apps from a single codebase using React Native and Flutter, published live on the App Store and Google Play

SaaS & MVP Development — subscription billing, multi-tenant architecture, and Stripe payments, built to scale

AI Integration — custom chatbots and assistants powered by GPT-4, Claude, and Gemini, trained on your own data (RAG)

Blockchain & Web3 — NFT marketplaces, smart contracts, and token launches on Solana and Ethereum

DevOps & Cloud — VPS, AWS, and DigitalOcean setup, CI/CD, security hardening, and 24/7 monitoring

Bug Fixing & Publishing — fast fixes and App Store / Play Store submissions, often within 24 hours

Our stack includes React, Next.js, TypeScript, Node.js, NestJS, React Native, Flutter, PostgreSQL, MongoDB, Python, and Web3.js.

Clients choose FIZNEX for clean, scalable code, fast communication, and an AI-first approach that gives their product a real edge. Whether you're validating an idea or scaling a platform, we build it the right way — start to finish.
