Full-Stack AI Developer — I build AI-powered web & mobile apps, AI agents, and cinematic AI video production with Higgsfield, Veo 3.1, Runway & Kling. 8+ years of deep learning experience turning "is this even possible?" ideas into shipped, revenue-generating products. Most clients need four hires for one AI product: app developer, ML engineer, automation specialist, backend dev. I'm all four — one accountable person from architecture to the launch of the product 🧠 AI AGENTS, LLMs & CHATBOTS Production-grade AI agents and RAG systems that answer from YOUR data — built with GPT-5, Claude, Gemini, Llama 4 & Mistral via LangChain, LlamaIndex & Amazon Bedrock. Voice AI agents (Vapi, Retell, LiveKit, Whisper, Deepgram, ElevenLabs) that handle real customer calls, not just demos. Vector search at scale: Pinecone, Weaviate, FAISS, ChromaDB. 📱 AI-POWERED WEB & MOBILE APP DEVELOPMENT Full-stack SaaS platforms, dashboards & mobile apps with AI at the core — Next.js, React Native, Flutter, Python. Deployed on AWS SageMaker, GCP Vertex AI & Azure with Docker/Kubernetes, optimized with TensorRT so your inference costs don't eat your margins. 🎬 AI VIDEO PRODUCTION & GENERATIVE MEDIA Product ads, UGC-style content, AI avatars & brand films using Higgsfield, Veo 3.1, Runway Gen-4.5, Kling & HeyGen — plus custom ComfyUI pipelines, ElevenLabs voice cloning, lip-sync, and FFmpeg/OpenCV post-production. Output that looks studio-made, not prompt-made. ⚙️ AI AUTOMATION & CUSTOM MODELS Workflow automation connecting LLMs to your CRM, WhatsApp & 100+ tools via n8n, Make & custom APIs. Fine-tuned, industry-specific models (LoRA, DreamBooth, ControlNet) when off-the-shelf isn't enough. WHY ME OVER THE OTHER 10 PROPOSALS → I don't just call APIs — I fine-tune, self-host and optimize models. Where API-wrapper freelancers hit a wall is where I start. → Your product and its marketing content share one brain, one vision. → Working demo or sample clip BEFORE you commit to the full build. Not sure if your idea is technically possible — or what it would cost? Send me ONE line describing it. Within 12 hours you'll get 2–3 concrete build approaches and an honest feasibility check. Free, no strings. 📩 Hit Invite or message me now — let's ship the product AND the content that sells it.
