I’m a Full-Stack Web & AI Developer based in Canada, with hands-on experience building production-ready web applications, automation workflows, and AI-powered systems for real business use cases.

I specialize in modern web development (Next.js, React, Supabase) and AI integrations (LangChain, LangGraph, OpenAI), helping clients turn ideas into scalable, reliable products. I’ve built full systems end-to-end — from database design and backend logic to clean, responsive front-end interfaces.

My recent work includes:

Developing AI agents capable of answering semantic, ranking, and time-sensitive queries using vector databases
Building full-stack platforms (authentication, payments, dashboards, admin tools)
Automating data workflows using n8n to reduce manual work and improve efficiency
Designing databases and APIs with performance, scalability, and maintainability in mind

I’ve worked as a Python Engineer, Full-Stack Developer, and AI Developer, and I also bring a strong analytical background from my experience as a Financial Analyst — meaning I focus not just on code, but on business value and clarity.

What I can help you with:

Custom websites & web apps (Next.js / React)
Backend & database design (Supabase, PostgreSQL)
AI chatbots, agents, and workflow automation
API integration & system optimization
MVPs for startups and small businesses

I value clear communication, clean code, and practical solutions. If you’re a local business or individual looking for a dependable developer who understands both technology and real-world needs, I’d be happy to help.
