🤝 More Than Just a Developer
For long-term clients, I work as a technical partner for their OpenCart store, not simply someone who fixes individual tickets.
From:
Analysis → Development → Testing → Deployment → Optimization → Ongoing Support
Whether you’re running a heavily customized legacy store, planning an upgrade, dealing with complex extension conflicts, or building something new, my experience helps reduce the trial-and-error that often comes with OpenCart development.
Clean code. Clear communication. Practical solutions.
No unnecessary complexity. No quick hacks that create bigger problems later.
📩 Let’s Work Together
Whether you need a quick OpenCart fix, custom development, an upgrade, performance optimization, or ongoing technical support, send me the details.
Tell me what you’re trying to achieve or what problem you’re facing — I’ll help you find the right solution.

I build Python automation tools that extract data and eliminate repetitive work.
Over the years I've delivered 10+ web scraping and bot projects with a 5.0-job success rate, including:
• Reservation bot for Resy — automated appointment booking at scale
• Amazon product scraper — extracted ASIN data
• PayPal invoice automation — reduced manual processing by 80%
• Messicks PDF data extraction — scraped equipment data from messicks website and extracted structured data from embedded PDFs
• Contact & business info extraction — extracted and consolidated contact and business information from multiple sources
• Ontario MLAS cell ID hunter — built a dedicated tool to search and extract cell IDs from Ontario's Mining Lands Administration System
• E-commerce data pipelines — seamless extraction from multiple platforms
I also provide ongoing maintenance — websites change constantly (layout, APIs, security), which breaks scripts. I leverage AI to monitor for breakage and patch scripts proactively, so your pipeline stays running.
What I work with:
Python • Selenium • BeautifulSoup • Playwright • AI-assisted Monitoring • LLM Integration • Browser Automation • API Integration • Data Processing • PDF Parsing
I don't just write code — I deliver working solutions that solve your real business problem, and I keep them running.
