About this gig
Are you tired of AI apps that look good but fail under pressure?
Most developers deliver a 'wrapper,' but I build production ready AI ecosystems.
From custom LLM integration (OpenAI, Anthropic, Llama) to sleek UI/UX, I handle the full lifecycle of your SaaS or Mobile App. I don't just write code; I solve the common AI issues like high latency, expensive API calls, and poor user retention.
CORE EXPERTISE:
- AI Integration: Chatbots, AI Agents, LangChain, RAG (Retrieval-Augmented Generation).
- Full-Stack Power: React Native/Flutter, Node.js, Python (FastAPI), Supabase/PostgreSQL.
- Design First: High-fidelity UI/UX that converts users.
WHY THIS GIG?
- Optimized API Usage: I build to keep your OpenAI/Anthropic bills low
- Scalable Backend: Your app wont crash when you hit 1,000+ users.
- Complete Documentation: You own 100% of the clean, commented code.
- Stop wasting time with developers who don't 'get' AI. Let's build a product that scales.️
NOTE: Every AI project is unique. Please message me first for a custom quote and technical consultation

FAQ
Do I need to provide my own API keys?
The user will need to provide their OpenAI, Anthropic, or other AI provider API keys. If the user does not have one, guidance through the setup process is available to ensure full control over billing.
Will the app be available for both iOS and Android?
The app can be built using cross-platform frameworks like Flutter or React Native. This ensures the AI app performs natively and beautifully on both Apple and Android devices with a single codebase
Do you provide the source code upon completion?
Once the project is finalized and delivered, the user receives 100% ownership of the clean, documented source code.
Can you integrate custom AI models or just ChatGPT?
Various integrations are available, including OpenAI (GPT-4), Claude, Gemini, and even open-source models via LangChain or Pinecone for specialized RAG (Retrieval-Augmented Generation) needs.
What if I don't have a design ready yet?
Custom UI/UX design is included in the Standard and Premium packages. A modern, user-friendly interface that aligns with the user's brand will be created before development.
Is the backend scalable for thousands of users?
The backends are built using Node.js, Python, or Supabase. Focus is on "serverless" or "optimized" architectures so the app stays fast, and hosting costs stay low.
Do you offer post-launch support?
A 14-day support window is offered for Basic/Standard packages and 21 days for Premium to ensure any bugs or deployment issues are handled immediately.
