I build AI-powered SaaS products and high-performance web applications that are designed to work reliably in the real world, not just look good in a demo.
If you need a developer who can take an idea from architecture → development → AI integration → deployment, I can handle the full stack.
I specialize in building AI SaaS platforms, web applications, dashboards, automation systems, API integrations, and custom business software using modern technologies including React, Next.js, TypeScript, Python, and AI/LLM APIs.
My approach is to understand the business logic first, then build the technical architecture around it. This helps avoid the common problems of rushed SaaS development: fragile integrations, poor database design, slow applications, difficult-to-maintain code, and AI features that don't work reliably in production.
### What I can build for you
✔ AI-powered SaaS platforms
✔ Custom web applications
✔ AI agents and automation systems
✔ LLM and OpenAI integrations
✔ React / Next.js frontends
✔ Python backends and APIs
✔ REST API & third-party integrations
✔ Admin dashboards and internal tools
✔ Authentication, subscriptions & payment systems
✔ Database architecture and optimization
✔ Real-time applications and communication systems
✔ MVPs and production-ready platforms
✔ Existing application modernization and performance improvements
### My Core Stack
Frontend: React, Next.js, TypeScript, JavaScript, Tailwind CSS
Backend: Python, FastAPI, Flask, Node.js
AI: OpenAI, LLM APIs, AI Agents, RAG, embeddings, computer vision, automation
Databases: PostgreSQL, MySQL, MongoDB, Redis
Integrations: REST APIs, webhooks, third-party SaaS/API integrations
Infrastructure: Docker, Linux, cloud deployment, CI/CD
I do not just write code I take ownership of the architecture, implementation, integrations, performance, and production readiness of the application.
If you're building an AI product, SaaS platform, or complex web application, send me the requirements and I'll help you turn them into a practical, scalable solution.
Available 40+ hours/week and comfortable working with US, Canada, UK, Australia, and other international teams.
