I build AI-powered SaaS platforms and AI voice agents that are fast, scalable, and ready for real users, not throwaway demos. I've helped build systems used by thousands of users, cut critical API response times by 40 to 60%, and shipped production platforms that scale without constant rewrites. Most recently I built an AI receptionist that answers calls in a natural voice, checks real availability, and books appointments without ever inventing a price or a time. Give me your idea and I'll turn it into a clean, reliable product with real AI built in. What I deliver - AI voice agents and AI receptionists: call handling, appointment booking, availability checks, caller memory, natural turn-taking, accent-robust speech recognition - End-to-end SaaS development: frontend, backend, database, deployment - AI features that hold up in production: LLMs, AI agents with tool calling, RAG pipelines, n8n automation - Grounded conversational AI: every answer verified against your business data, so the model can't hallucinate a booking, a price, or a policy - Multi-tenant architecture with secure data isolation and RBAC - Stripe subscriptions: billing, webhooks, lifecycle automation - High-performance REST and GraphQL APIs - Scalable databases: PostgreSQL, Supabase, MongoDB - Real-time systems: WebSockets, streaming audio, event-driven architecture How I work - I don't just write code, I design systems that last. - Clean, modular architecture from day one - No overengineering, no shortcuts that break later - Clear, proactive communication - I take ownership and improve your product, not just follow the spec AI as a core tool, not a crutch I use AI to move faster and smarter: rapid prototyping, sharper debugging, and production-grade LLM integrations (OpenAI, Claude) tuned for cost, latency, and reliability. For voice agents that means streaming replies that start speaking in under a second, deterministic booking logic the model can't override, and evaluation suites built from real call transcripts. Everything is reviewed and structured, never low-quality AI-generated code. Projects I focus on AI receptionists and voice agents for salons, clinics, studios and service businesses · SaaS platforms (B2B / B2C) · AI products and automation tools · dashboards and internal tools · subscription platforms and marketplaces · data-heavy apps (analytics, fintech, reporting) Tech stack Frontend: Next.js, React, TypeScript, Tailwind Backend: Node.js, NestJS, Python (FastAPI) Database: PostgreSQL, Supabase, MongoDB AI: OpenAI, Claude, RAG, vector databases, LLM tool calling, n8n Voice AI: Twilio, Deepgram, ElevenLabs, Web Speech API, LiveKit / Vapi / Retell Infra: Vercel, AWS, Docker, CI/CD Building something serious and want it done right the first time?
