About this gig
TRANSFORM YOUR BUSINESS INTO AN AI-POWERED POWERHOUSE
Stop building reactive bots. In 2026, winners deploy autonomous "digital colleagues" that proactively manage workflows. I specialize in AI-native mobile experiences where intelligence is the foundation, not just an add-on.
WHY WORK WITH ME?
As a senior developer with an exceptional number of repeat buyers, I deliver bug-free, high-performance solutions. My clients value my ability to translate vision into 60-120 FPS mobile reality.
WHAT I OFFER:
- Model-Agnostic AI Agents: Integration with ANY LLM (GPT-4o, Claude 3.5, Llama 3.1) for lead gen, scheduling, and CRM automation via Make.com.
- High-Performance Apps: iOS/Android development using Flutter (Impeller) or React Native with sub-2s launch times.
- Voice AI: Natural voice agents (Vapi, Bland, Retell) with sub-700ms latency.
- On-Device ML: Privacy-focused local processing for real-time tasks.
TRUE COST TRANSPARENCY:
I provide full TCO breakdowns: $Total = C_{platform} + C_{telephony} + C_{stt} + C_{llm} + C_{tts}$. Expect $0.150.36/min production costs.

FAQ
Do I have to use OpenAI, or can we use other AI models?
I am completely model-agnostic. Depending on your project’s needs for speed, cost, or reasoning, I can build your AI agent using any LLM, including OpenAI GPT-4o, Claude 3.5 Sonnet, or even open-source models like Llama 3.1 for private deployments.
What is the difference between a standard chatbot and an "Autonomous AI Agent"?
A chatbot simply responds to prompts. An autonomous AI agent is a "digital colleague" that can take actions. My agents can autonomously read emails, schedule meetings, update your CRM, and handle multi-step workflows across web, WhatsApp, and voice channels without human oversight.
Will my AI mobile app work on both iOS and Android?
Yes. I specialize in high-performance cross-platform development using Flutter and React Native. Your AI mobile app will feature sub-2-second launch times and smooth 60-120 FPS animations, ensuring a native-like experience on both platforms.
Who covers the costs for the AI tokens and phone minutes?
This gig follows a "Bring Your Own Key" (BYOK) model. You will provide your own API keys for services like OpenAI or Vapi AI. I will help you set these up and provide a True Cost of Ownership (TCO) breakdown so you understand exactly what you will pay per minute or per thousand tokens.
Can the AI be trained on my private company data?
Absolutely. I implement Retrieval-Augmented Generation (RAG) using vector databases like pgvector. This allows your AI agent to provide 98%+ accurate, hallucination-free answers based directly on your private PDFs, spreadsheets, or internal documentation.
How natural do the voice agents sound, and is there a delay?
By using industry leaders like Vapi AI, Bland AI, and Retell AI, I deliver human-like voice agents with sub-700ms latency. This ensures your customers experience fluid, real-time conversations that are indistinguishable from a human support representative.
Can you integrate the AI agent into my existing mobile app or website?
Yes. Whether you need a full-stack build from scratch or want to add AI integration to an existing system, I can connect your app to any LLM backend via custom API architectures.
