Need a production-ready AI system — RAG pipeline, LLM integration, or intelligent automation? I build full-stack AI applications with Python and Next.js that go live, not just demos. 6+ years, $50K+ earned on Upwork, Top Rated Plus.
I sit at the intersection of AI engineering and full-stack development — which means I don't just wire up an API call and call it an AI product. I design the data pipeline, the retrieval layer, the LLM orchestration, and the frontend interface as a single cohesive system. Most clients come to me after a previous developer delivered a fragile prototype. I deliver production systems.
My core stack: Python, FastAPI, LangChain, RAG, LLM fine-tuning, Next.js, React, Node.js, PostgreSQL, MongoDB, AWS, Azure.
Here is what I build:
Full-Stack Apps — Next.js + React frontends connected to AI-powered backends
AI Agents — WhatsApp bots, voice agents, inbound/outbound call agents, customer support automation
RAG Systems — document Q&A, PDF + SQL retrieval, enterprise knowledge bases
LLM Integrations — OpenAI, Anthropic, fine-tuning, prompt engineering, model evaluation
Backend APIs — FastAPI, REST, GraphQL, scalable Python microservices
AI Data Pipelines — ETL, scraping, clustering, vector search, resume parsing
Automations — n8n, Zapier-style workflows, social media automation
Proofs
Top Rated Plus on Upwork (top 3% of talent)

I build AI-powered SaaS platforms and full-stack MVPs with Next.js, React, and Node.js — helping founders take products from idea to launch in weeks, not months.
Top Rated Plus on Upwork, 100% Job Success across 500+ projects and 3,400+ hours. Recent work: an AI SaaS MVP for a healthtech startup that helped secure its seed round; a Stripe-powered booking platform now processing 10,000+ transactions a month at 99.9% uptime; and a React/Node fintech dashboard that cut data-processing time 3x across millions of records.
How I can help:
🔹 AI SaaS & MVP development — OpenAI/Claude API integration, AI chatbots, workflow automation (n8n), built on Next.js and Node.js
🔹 Full-stack web applications — React, TypeScript, Express.js, PostgreSQL/MongoDB, engineered for clean architecture that scales
🔹 API & payment integrations — Stripe, REST/GraphQL, secure third-party integrations, documented and production-ready
I work directly with founders and technical leads: clear scoping up front, regular progress updates, and code another engineer can pick up without a rewrite. Available for both fixed-scope builds and long-term SaaS partnerships.
Core stack: Next.js, React, Node.js, TypeScript, Express.js, PostgreSQL, MongoDB, Stripe, OpenAI API, AWS, Docker, GraphQL, REST APIs. Also available for React Native/Flutter mobile builds and Laravel/Vue.js projects on request.

If you need an AI system, SaaS platform, or cloud backend built right the first time - without the back-and-forth, scope creep, and "we'll figure it out later" approach - you're in the right place.
✔️ I work best with founders and product teams who are thinking:
- "I need an AI agent or LLM system that actually works in production, not just a prototype"
- "I need someone who owns the architecture, not just the code"
- "I've been burned by developers who disappear after delivery - I need reliability"
- "I need the full stack handled - frontend, backend, DevOps, AI - by one person who gets it all"
✔️ Working with me, you get:
🌟 End-to-end ownership: from system architecture and AI integration to deployment, scaling, and ongoing automation
🌟 Production-grade AI systems: RAG pipelines, multi-agent workflows, LLM integrations using LangChain, OpenAI, and Claude
🌟 Cloud-native infrastructure: AWS, Azure, GCP, Docker, Kubernetes, CI/CD - built to scale from day one
🌟 12+ years of full stack depth: React, Node.js, Next.js, Python, Django, GraphQL, and more
✔️ We might not be the right fit if:
✗ You need the cheapest option available - I focus on quality and long-term value, not the lowest bid
✗ You have no clear vision for what you're building - I work best with founders who know their product direction
✗ You need someone to "just code" without thinking about architecture or outcomes

What I bring that most developers don't - I don't just write code. I make architecture decisions, set up infrastructure, automate the deployment pipeline, and ensure the system scales correctly from day one. You get a single point of ownership across the entire build, not a developer who stops at the code and hands off the rest.
If your project involves AI agents, LLM integration, SaaS platform development, or cloud infrastructure - and you need someone who can own it end to end - let's talk. A 20-minute call is usually enough to know if we're a good fit.
