I build AI-powered applications that actually ship — from chatbots and RAG systems to full SaaS platforms.
Helped startups build scalable AI backends, automate workflows, and launch production-ready LLM products using OpenAI, FastAPI, and modern cloud stacks.
What I focus on
-AI / ML Systems: RAG pipelines, LLM fine-tuning, embeddings, vector search, LangChain, LangGraph, MCP
-Backend & APIs: Python, FastAPI, Node.js, async architectures, authentication, observability
-Full-Stack Applications: React, Next.js, real-time dashboards, AI-driven UX
-Cloud & DevOps: Docker, Kubernetes, AWS (EKS, ECR, S3), GCP, Cloudflare R2
-Data & Storage: SQL, MongoDB, vector databases, object storage
-AI Integrations: OpenAI / GPT, custom model pipelines, multimodal systems (YOLO, RCNN)
Typical projects I work on
-RAG-based knowledge assistants and internal copilots
-AI SaaS backends with FastAPI + React/Next.js
-Scalable LLM inference and orchestration on Kubernetes
-Secure document ingestion pipelines (PDFs, S3/R2, embeddings)
-End-to-end AI products deployed on AWS or GCP
I’ve delivered production systems including AI-powered web platforms and mobile apps with intelligent features, handling everything from architecture and deployment to performance tuning and monitoring.
If you’re building an AI-first product, need to productionize an LLM idea, or want a backend that won’t collapse at scale, let’s talk.

Top Rated Plus | 100% Job Success | Co-Founder & CTO of PropertyTools .ai, a live AI SaaS platform. I don't just write code - I build and run production systems that real businesses depend on daily.
Two things I do exceptionally well:
1. Full stack web apps & SaaS platforms (Next.js, React, Python, Django, FastAPI, Node.js)
2. AI agents, chatbots & automation systems (OpenAI, Claude API, LangChain, RAG, n8n)
🏆 PROOF, NOT PROMISES — live products I built:
- PropertyTools .ai — AI real estate SaaS I co-founded: Claude AI document analysis, Plaid bank integration, Stripe subscriptions, multi-tenant architecture
- BlueGrassHopper .com — multi-tenant fintech marketplace: Django, React, Stripe Connect payouts, 4 role-based dashboards
- BNTR.ai — AI chatbot builder that trains on your own data (React, Django, custom ML)
- GetOdin.ai — led a full Next.js → React migration that fixed a slow production app
- Recent client win: brought an unstable production app to life — "running in prod error free" (see reviews)
🔧 TECH I SHIP WITH DAILY:
Backend & APIs: Python (Django, FastAPI), Node.js (NestJS, Express), REST, GraphQL, WebSockets
AI & Automation: AI agents (LangChain, LangGraph, CrewAI), RAG pipelines, OpenAI GPT-4o, Claude API, chatbots, voice AI, n8n / Make / Zapier workflows
Frontend: React, Next.js, TypeScript, Tailwind CSS
Data & Infra: PostgreSQL, MongoDB, Redis, Supabase, AWS, Docker, CI/CD
Payments & Fintech: Stripe, Stripe Connect, Plaid, PayPal
🚀 VIBE CODED YOUR APP? I'LL MAKE IT PRODUCTION-READY.
Built something with Lovable, Bolt, v0, Replit, or Cursor and now it's breaking, insecure, or impossible to extend? This is one of my specialties — I take AI-generated codebases and turn them into stable, scalable products. Auth done right, database restructured, security holes closed, deployed properly. A recent client's unstable app has been "running in prod error free" for months (see reviews).
💡 WHY CLIENTS PICK ME:
- I run my own live SaaS — I think about your product like a founder, not a task-taker
- AI-native development: I use Claude Code and Cursor daily, so you get senior-level quality at 2-3x normal speed — you pay for outcomes, not hours of typing
- Working demos, not slide decks — I'll screen share real production systems on our first call
- 0–4 hour response time, clear communication, realistic timelines
✅ GREAT FIT: SaaS MVPs, AI agents & chatbots, vibe code cleanup & rescue, scalable APIs, fintech integrations, rescuing unstable production apps
❌ NOT A FIT: cheapest-bid shopping, gambling/adult content
🎯 GUARANTEE: Clear expectations set upfront. If I don't deliver against them, full refund.
Message me — I'm usually online and can jump on a call the same day.

𝐈 𝐨𝐟𝐟𝐞𝐫 𝐚 𝟓-𝐃𝐚𝐲 𝐫𝐢𝐬𝐤-𝐟𝐫𝐞𝐞 𝐭𝐫𝐢𝐚𝐥: 𝐈 𝐬𝐭𝐚𝐫𝐭 𝐛𝐮𝐢𝐥𝐝𝐢𝐧𝐠 𝐲𝐨𝐮𝐫 𝐬𝐨𝐥𝐮𝐭𝐢𝐨𝐧 𝐰𝐢𝐭𝐡 𝐲𝐨𝐮𝐫 𝐝𝐚𝐭𝐚 – 𝐲𝐨𝐮 𝐜𝐨𝐧𝐭𝐢𝐧𝐮𝐞 𝐨𝐧𝐥𝐲 𝐢𝐟 𝐲𝐨𝐮 𝐬𝐞𝐞 𝐭𝐡𝐞 𝐫𝐞𝐬𝐮𝐥𝐭𝐬.
I'm a Machine Learning Engineer and former Aerospace Engineer, founder of Gless AI – a Toronto-based AI agency. I specialize in RAG, Large Language Models, Chatbots, and AI agents.
𝐖𝐡𝐚𝐭 𝐈 𝐜𝐚𝐧 𝐛𝐮𝐢𝐥𝐝 𝐟𝐨𝐫 𝐲𝐨𝐮:
- AI agents that automate multi-step workflows (sales ops, support, internal tools)
- Chatbots that handle real customer conversations - not just FAQs
- RAG systems that turn messy documents into accurate, reliable answers
- AI pipelines that process text, images, audio, and documents into structured outputs
- End-to-end LLM integrations into your existing systems (CRM, ERP, APIs)
𝐓𝐞𝐜𝐡 𝐬𝐭𝐚𝐜𝐤 (𝐩𝐫𝐨𝐝𝐮𝐜𝐭𝐢𝐨𝐧-𝐫𝐞𝐚𝐝𝐲):
- AI Agents & Workflows: LangGraph, MCP, Agentic RAG, OpenClaw, n8n
- LLMs: OpenAI (GPT-4/5), Claude, Gemini, Mistral, Llama, Qwen
- RAG & Vector DBs: Qdrant, Milvus, FAISS, hybrid search, GraphRAG, Pinecone
𝐃𝐚𝐭𝐚 𝐏𝐫𝐢𝐯𝐚𝐜𝐲 & 𝐎𝐰𝐧𝐞𝐫𝐬𝐡𝐢𝐩:
- On-premise deployment available – your data never leaves your infrastructure
- Full source code handoff – no vendor lock-in, no monthly fees
- Open-source models (LLaMA, Mistral, Qwen) deployable on your own servers for regulated industries
I’m transparent about scope, timelines, and feasibility. I don’t promise unrealistic “build ChatGPT in a week” projects - I deliver working systems that actually solve the problem.
𝐖𝐡𝐲 𝐢𝐭 𝐰𝐨𝐫𝐤𝐬:
· I'm straightforward – if your problem can be solved simply, I'll tell you that instead of overselling
· I move fast – most clients see a working prototype within 2 days
· You own everything – full source code, no subscriptions, no lock-in
· I've built and sold a business myself, so I treat your budget like mine
