Need AI that goes live and gets used? I build it: a Voice AI teacher that runs real classes, an AI receptionist that answers real customer calls, both inside multi-tenant SaaS with billing and tenant security intact. If your last AI project stalled at the demo, that is the gap I close. With six years of full-stack and backend engineering behind the AI, I build AI agents, RAG systems, Voice AI assistants, and chatbots, including the auth, multi-tenancy, usage metering, and billing that real software needs. You work with one engineer who owns the feature end to end, from the model to the database to the invoice. WHAT I BUILD - Voice AI agents and assistants for calls and live sessions, role-scoped so prompt injection cannot reach another tenant’s data - RAG and knowledge-base chatbots with per-tenant context, tuned to follow up honestly instead of inventing answers - Generative AI and LLM integration into your product (OpenAI API, AI model integration), with credit wallets, usage metering, and per-session billing via Stripe Connect - Full-stack delivery: an e-commerce engine handling 300,000-plus products and a booking platform that lifted online bookings by 40 percent at a 90-plus Lighthouse score PAST WORK - VineLMS (AI learning platform): a live Voice AI teacher that lectures and takes student questions in real time, a course generator that turns a topic or lecture into a complete validated course in one pass, a course-aware tutor, a child-safety layer, and an AI-credit billing system - Smart Track CRM: an AI call receptionist that answers overflow calls, qualifies leads, and creates CRM records; a chatbot across web, WhatsApp, Messenger, and Instagram with a unified staff inbox; and a self-updating knowledge base - Earlier experience: backend and full-stack roles in PHP, Laravel, and Vue since 2021 TECH STACK OpenAI (Realtime, GPT-4o, Whisper, TTS, moderation), Generative AI, RAG, semantic search, prompt engineering, tool calling; LiveKit, Vapi, Twilio; TypeScript, Python, PHP; Node.js, AdonisJS, Laravel; Next.js, React, Vue; PostgreSQL, MySQL, Elasticsearch, pgvector, Pinecone, Qdrant; Stripe and Stripe Connect; AWS, Docker, Vercel, CI/CD; WhatsApp and Meta integrations.
