AI tools are shipping more apps than ever. They are also shipping more bugs than ever. I fix them. I work with Claude Code and use advanced capabilities like MCP, Skills, and subagents to streamline complex workflows, automate repetitive engineering tasks, and significantly increase my development speed. I know these tools well. That is exactly why I can spot what goes wrong when they are used carelessly. I am a senior full-stack engineer with 7+ years of experience in PHP, Laravel, and VueJS. I specialize in jumping into existing codebases, finding what is broken, and fixing it properly. Not just patching symptoms. Finding root causes. Reading code I did not write is something I do fast. Whether it is a bug introduced by an AI assistant, a broken deployment, or a performance issue nobody can explain, I can diagnose it and resolve it. Here is what I work on: • Bugs and errors in PHP, Laravel, Livewire, and VueJS applications • Broken or unstable websites and web apps • Slow queries, poor database performance, and code bottlenecks • AI-generated or messy code that needs to be cleaned up and made maintainable • Server, deployment, and configuration issues on AWS My track record on Upwork: • Top Rated Plus (Top 3%) • 100% Job Success Score • AWS Certified Cloud Practitioner My Tech Stack: • Front-End: JavaScript, jQuery, VueJS, VueCli, VueX, Bootstrap, Tailwind, AlpineJS • Back-End: PHP, Laravel, Lumen, Livewire, Filament, TALL Stack, SQL, MongoDB • Third-Party Integration: PayPal, Stripe, Twilio, EasyPost, Walmart API, eBay API • Tools & Technologies: Web-Sockets, FFMPEG, MySQL, Git, n8n, OpenAI Agents SDK • Cloud Services: AWS (EC2, RDS, S3, SNS, SES, SQS, Load-Balancing) If your app is throwing errors, running slowly, or just behaving in ways it shouldn't, send me a message. Please tell me what is happening, and I will take a look.

I help businesses automate repetitive work by building reliable scraping systems, data pipelines, and workflow automation tools. Over the last 15+ years, I’ve worked on projects involving large-scale web scraping, Excel/VBA automation, API integrations, eCommerce product pipelines, reporting systems, and structured data processing. Most of my recent work focuses on: • Web scraping and browser automation • Data extraction from marketplaces, directories, and dynamic websites • Backend automation workflows • Scheduled scraping pipelines • Data cleaning, normalization, and deduplication • Excel, Google Sheets, and database integrations I’ve worked on systems involving: • Ticketmaster inventory/event pipelines • WooCommerce vendor-feed automation • Marketplace monitoring and pricing workflows • Product catalog processing • Public-record and structured dataset extraction • Large CSV/database processing systems Tools I commonly work with: Python, Playwright, Selenium, Requests, BeautifulSoup, VBA, APIs, PostgreSQL, MySQL, SQL Server, Google Sheets, Excel automation. I focus on building automation systems that are stable, maintainable, and actually useful long-term — not just quick scripts that break after a few weeks. I’m comfortable working on: • One-time extraction projects • Ongoing scraping/monitoring systems • Data cleanup and processing workflows • Backend automation support • Long-term maintenance projects If you need reliable automation and clean structured data, I’d be happy to discuss your project.
