Full-Stack & AI Engineer | GenAI/LLM/RAG | AI Agent & SaaS Development

I'm a Full-Stack & AI Engineer specializing in architecting and building scalable SaaS platforms powered by modern cloud infrastructure and applied artificial intelligence. I design production-grade systems that aligh technical architecture with business growth, operational efficiency, and long-term product strategy. I work with founders and product teams who need more than feature development - they need strucured systems, clean architecture, and senior-level execution capable of supporting real growth. From MVP validation to high-scale infrastructure, I build platforms engineered for reliability, security and evolution. -------------------------------------------------------- SAAS PLATFORM ENGINEERING I design and develop end-to-end SaaS applications using: - React, Next.js, JavaScript, TypeScript - Node.js, Express, Python (Flask, FastAPI, Django) - RESTful APIs, GraphQL, WebSockets - Multi-tenant architecture & subscription systems - Secure authentication (JWT, OAuth) & role-based permission - Admin dashboards & internal operational tooling - Stripe payment integrations - API-first and modular backend architecture -------------------------------------------------------- AI SYSTEMS & INTELLIGENT AUTOMATION I integrate advanced AI capabilities directly into SaaS platforms to create measurable competitive advantages: - AI Agents & autonomous workflow systems - Enterprise-grade chatbots & conversational AI - OpenAI & Large Language Model integration - Retrieval-Augmented Generation(RAG) architectures - AI copilots embedded into product workflows - Voice AI systems (speech-to-text / text-to-speech pipelines) - AI Avatar (Simli, HeyGen, Tavus） - Intelligent document processing, summarization & classification - Automation systems that reduce operational overhead -------------------------------------------------------- ARCHITECTURE, DATA & INFRASTRUCTURE - PostgreSQL, MongoDB, MySQL, Firebase, Superbase - Scalable data modeling & query optimization - Event-driven systems & background job processing - AWS, GCP, Microsoft Azure - Docker & containerized deployments - CI/CD automation & performance optimization - Monitoring, logging & performance optimization - High-concurrency system design -------------------------------------------------------- WHAT CLIENTS ENGAGE ME FOR - Building SaaS platforms from 0 - 1 with strong technical foundations - Scaling and stabilizing existing platforms - Embedding AI into revenue-generating workflows - Refactoring legacy systems into clean, modular architectures - Providing senior-level execution without micromanagement I operate with a product-first mindset - aligning engineering decisions with user experience, scalability requirements, and measurable business outcomes. If you are building a serious SaaS platform or AI-powered product and require senior technical leadership with hands-on execution, I'm ready to contribute.

Work Terms

1. Engagement Model • Fixed-price projects with clearly defined scope & milestones • Hourly engagements for architecture, advisory, or ongoing development • Long-term partnerships preferred for SaaS and AI product evolution 2. Project Process My execution framework: • Requirements & Product Clarification • Architecture & Technical Planning • Milestone-Based Development • Testing & Performance Validation • Deployment & Production Hardening • Post-Launch Optimization (if applicable) 3. Communication • Direct communication with founders / decision makers preferred • Weekly progress updates (or more frequent if needed) • Clear roadmap • Transparent technical recommendations I operate independently and do not require micromanagement. 4. Payment Structure • 30–50% upfront for fixed-price projects • Milestone-based release structure • Hourly contracts billed weekly • Larger systems divided into logical delivery phases 5. Technical Standards All work follows: • Clean, modular, production-grade architecture • Scalable system design • Secure authentication & data protection practices • Cloud-ready deployment standards • Performance monitoring considerations 6. What I Don’t Do • Low-budget quick fixes without clear scope • Undefined feature lists without technical planning • Projects lacking product direction If you need structured engineering leadership and scalable execution, we will work well together.
