I will build your web application frontend and backend from scratch
James Felicia
About this gig
Need software built properly not patched together? I'm a full stack developer who handles the frontend, backend, and everything connecting them.
Whether you need a complete custom application, a specific feature added to an existing system, or a broken codebase fixed and stabilized, I write clean, working code and ship it.
What I build:
- Full web applications, frontend to backend
- REST APIs and backend services
- Databases designed for how your app actually scales
- Admin dashboards and internal tools
- Integrations with payment gateways, CRMs, and third-party APIs
- My stack: JavaScript/TypeScript, React, Node.js, Python, PostgreSQL/MongoDB, and cloud deployment on AWS or Vercel adjusted to whatever fits your project best.
How I work:
- Send me what you're building or what's broken
- I scope it honestly cost, timeline, what's realistic
- I build it, keep you updated at milestones, and deliver working code
- Message me with your project and I'll tell you exactly what it takes.

Full-stack & AI developer building AI SaaS platforms, websites, chatbots, and automations from scratch — plus fixing, completing, and deploying apps built on base44, lovable, bolt, replit and manus ai.
I work across React, Node.js, Python, Supabase, and integrate OpenAI, Claude, and Gemini depending on the project. Every job starts with an honest scope: realistic timeline and budget before any code gets written.
Message me with what you're building or what's broken.
FAQ
Do you handle both frontend and backend, or just one?
Both — that's the point of a full stack gig. If you only need one side, that's fine too, just let me know in your message.
I have an existing codebase with bugs. Can you fix it instead of rebuilding?
Yes, in most cases. Send me the repo and a description of the issues, and I'll tell you honestly whether fixing or rebuilding makes more sense.
What languages/frameworks do you work in?
JavaScript/TypeScript (React, Node.js) and Python are my primary stack. I can also work in PHP or other stacks depending on the project — ask if you're unsure.
Can you build a specific feature into my existing app?
Yes, this is common — send me access to the repo and a clear description of what you need added.
Do I own the code afterward?
Yes, fully. You get the complete source code on delivery.
What if the project is bigger than the packages listed?
The packages are starting points. For larger custom builds, message me first with your requirements and I'll send a custom quote.
