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.
