I will develop a full stack web application with react and python
John
About this gig
I build production-ready web applications from the ground up fast backends, polished frontends, and everything in between.
My stack:
Frontend: Next.js 15, React 19, Tailwind CSS, shadcn/ui
Backend: Python 3.12, FastAPI, async/await, Pydantic validation
Database: PostgreSQL 16, Redis, SQLAlchemy 2.0
Auth: JWT access + refresh tokens, bcrypt, optional 2FA
Deployment: Docker, GitHub Actions CI/CD, nginx
What you get:
Clean, typed, maintainable code not a WordPress template
Fully responsive UI that works on every screen size
RESTful API with complete documentation (auto-generated OpenAPI/Swagger)
Input validation on every boundary (Pydantic + Zod)
Security baked in: OWASP Top 10 compliant, parameterized queries, rate limiting
I've built:
SaaS dashboards with real-time data
E-commerce platforms with Stripe integration
CRM systems with role-based access
Client portals with file management
Internal tools that replaced spreadsheet workflows
Every project includes:
Source code (GitHub repo or zip)
API documentation
Deployment guide
30 days of bug-fix support
I don't build cookie-cutter sites. I build tools that solve real problems. Message me with your project idea!

Custom software, AI systems, and secure infrastructure
What I build:
• AI chatbots & voice agents (custom-trained models, not wrapper APIs)
• Full-stack web applications (Python/FastAPI, Next.js, React, Tailwind)
• Automation scripts & bots (Discord, scraping, data pipelines)
• Security audits & penetration testing (certified, Network Security+)
• Cloud infrastructure (Docker, nginx, PostgreSQL, Redis — hardened production deployments)
I run my own GPU cluster and train my own AI models. When I say "custom AI," I mean it, not a ChatGPT wrapper.
Fast delivery.

FAQ
What frontend framework do you use?
Next.js 15 with React 19 and Tailwind CSS. This gives you server-side rendering for SEO, fast page loads, and a modern component-based UI. I use shadcn/ui for polished, accessible components.
Can you integrate with my existing API or database?
Absolutely. I can build a frontend for your existing API, extend an existing backend, or migrate from another stack. I'll review your current setup and propose the cleanest integration path.
Do you deploy the app for me?
Yes (Pro and Enterprise tiers). I'll containerize with Docker, set up CI/CD via GitHub Actions, and deploy to your hosting provider (AWS, DigitalOcean, Railway, Vercel, or your own server).
Will I own the source code?
100%. You get full ownership of all code. I deliver via a private GitHub repo or a zip file — your choice.
What about ongoing maintenance?
Every project includes 30 days of free bug-fix support. After that, I offer monthly maintenance packages or you can rehire me for feature additions.
