22+ products built end-to-end. 6 running at enterprise scale. Clients include Odiggo (YC S21), Time Health (piloted by the largest healthcare network in the US) and Cravta (#1 women-led startup in MENA). I specialise in building full-stack applications with AI and Web3 at the core; using Python, Next.js, FastAPI, Node.js, React Native, MERN, and AWS. From RAG pipelines and AI voice agents to blockchain escrow systems, I build the full product, not just the feature layer. 𝐓𝐡𝐞 𝐦𝐨𝐬𝐭 𝐫𝐞𝐜𝐞𝐧𝐭: an AI voice receptionist built on Retell with Sonic 3 TTS, running sub-500ms latency over WebRTC, powered by LLM agents, Twilio, and WhatsApp; recovered $81K in annual revenue for a dental practice in 30 days. Before that, an on-prem Whisper + RAG system with Python and machine learning that cut clinical workload by 60% for 𝐓𝐢𝐦𝐞 𝐇𝐞𝐚𝐥𝐭𝐡. Before that, a computer vision pipeline for 𝐀𝐠𝐫𝐢𝐓𝐞𝐜𝐡 that closed a $2.1M seed round as the lead technical differentiator. 𝐖𝐡𝐚𝐭 𝐈 𝐛𝐮𝐢𝐥𝐝: ▸ Full-stack applications: Next.js, FastAPI, Node.js, React Native, GoLang, PostgreSQL, MongoDB, Redis. End-to-end product builds from architecture to deployment. ▸ AI voice & LLM agents: AI receptionists, AI tutors, AI companions, clinical assistants (Retell, LiveKit, Sonic 3, Twilio, WhatsApp, Whisper, LangChain, EMR/PMS integrations, sub-500ms WebRTC latency) ▸ RAG pipelines: semantic search + BM25 hybrid retrieval, multilingual & multimodal document AI, real-time compliance systems (Qdrant, Pinecone, ChromaDB) ▸ LLM fine-tuning & prompt engineering: LoRA/PEFT on GPT, LLaMA, Mistral, Gemini for domain-specific use cases, not just API wrappers ▸ Computer vision: face recognition, liveness & deepfake detection, biometric KYC (1:1, 1:N), medical imaging, satellite imagery, multilingual OCR (YOLO, Transformers, PyTorch) ▸ Classical ML: XGBoost, time series forecasting, yield prediction on IoT and sensor data ▸ Web3 & blockchain: smart contracts, NFT minting, escrow systems, Polygon chain, wallet integrations, crowdfunding platforms ▸ Automation & workflows: N8N, Zapier, Claude Code, custom pipeline orchestration 𝐖𝐡𝐞𝐫𝐞 𝐈 𝐚𝐝𝐝 𝐭𝐡𝐞 𝐦𝐨𝐬𝐭 𝐯𝐚𝐥𝐮𝐞: ▸ You have an idea or a vision and need someone who can architect it, build it, and ship it, not just write code to a spec. ▸ You have a working MVP and need to take it to an enterprise-grade, scalable product without rebuilding from scratch. I have done both, multiple times. I led Cravta, Khurli, Sawie, AgromAi, and Odiggo (YC S21) from ideation or early stage through to enterprise-grade products. I work the way a technical co-founder would: I'll flag problems before they get expensive, communicate without being chased, and build systems I'd be comfortable owning long-term. 𝐑𝐞𝐜𝐞𝐧𝐭 𝐰𝐨𝐫𝐤: ▸Khurli: AI voice dental receptionist built on Retell with Sonic 3 TTS, sub-500ms end-to-end voice latency over WebRTC, Twilio & WhatsApp integration, and Dentrix EMR sync. 41 new patients captured in 30 days. $81K annual revenue recovered. 6.1x ROI in month one. ▸Time DRH: On-prem Whisper + RAG agents for clinical workflows. EMR-optimized transcriptions with AI-assisted diagnosis and prognosis. 60% reduction in manual workload. Piloted by Time Health across the US. ▸Cravta & Huda: Multilingual computer vision EdTech platform with gamified learning, in-product marketplace, multi-tenant architecture, and white-label support. Includes Huda, a real-time conversational AI tutor built on LiveKit. Led from ideation to enterprise. 1,000+ users. 40% performance gain. 30% cloud cost reduction. Ranked #1 Women-Led Startup in MENA. ▸Sawie: Computer vision + crop health classification for AgriTech. $2.1M seed round closed with this as the lead technical differentiator. ▸AgromAi: Soybean yield prediction in Brazil using XGBoost trained on IoT sensor data, weather, and soil inputs. Piloted by Bank of Brazil. ▸Vasael: Real estate & commodities crowdfunding platform processing $2M+ in annual transactions. Blockchain-powered escrow with NFT minting on Polygon, payment gateways, MFA, and biometric authentication. ▸Crypto Compliance RAG: Real-time multilingual, multimodal RAG system for GCC crypto compliance with live regulatory document ingestion. ▸Additional portfolio: Odiggo (YC S21), ColorsofRiyadh, RDP-KSA, Oliva-SA, in2o, and more. If any of this sounds like what you're trying to build, send me a message. I'd love to hear what you're working on and show you how I'd approach it.
