I build production-ready SaaS platforms and custom AI (RAG) agents that automate complex business logic. I specialize in Python, React, and LLM integration to build scalable, revenue-focused systems.
Core Engineering Capabilities
1. SaaS MVP & Application Architecture
End-to-end development utilizing React (Next.js), Node.js, and Python (FastAPI).
Scalable relational and NoSQL database design (PostgreSQL, Supabase, MongoDB).
Secure API integrations for FinTech and enterprise operations (Stripe, Xero, custom REST/GraphQL).
2. AI Integration & Autonomous Agents
Custom RAG (Retrieval-Augmented Generation) pipelines allowing LLMs to interact securely with your proprietary business data.
Advanced LLM orchestration using LangChain alongside OpenAI, Claude, and Gemini APIs.
Vector database implementation (Pinecone) for semantic search, context retrieval, and agent memory.
3. Workflow Automation & Infrastructure
Complex business logic automation via n8n, Zapier, and custom webhooks.
Cloud deployment and containerization (AWS, Docker) ensuring high availability and fault tolerance.
CRM and ERP data synchronization (HubSpot, Zoho, Airtable) to eliminate manual entry.
Engineering Philosophy & Execution
Architectural Rigor: I build for scalability from day one, anticipating state management bottlenecks and database constraints before they impact production.
Business-Driven Logic: Technology must serve the bottom line. I prioritize features and integrations that drive operational efficiency and user retention.
Transparent Cycles: Clean documentation, strict version control, and consistent deployment updates. You are never left guessing the status of the repository.
Technical Stack Overview:
Frontend: React.js, Next.js, TypeScript, Tailwind CSS
Backend: Python (FastAPI/Django), Node.js, Go (Golang)
AI & Data: LangChain, OpenAI/Claude/Gemini APIs, Pinecone
Infrastructure & DB: PostgreSQL, MongoDB, Supabase, AWS, Docker
Automation Tools: n8n, Zapier, Webhooks
Next Steps:
If you require a technical partner to architect your SaaS or integrate custom AI workflows, invite me to your job. We can discuss your system architecture, data constraints, and deployment timeline.
