25+ years exp. - Full stack web developer, integrity is one of my core values. If you are looking for someone you can trust who has been building custom web solutions successfully for a long time, look no further. AI model integration, machine learning APIs, Stripe connect and custom Stripe checkouts, automated testing with AI. I build with the TALL stack ( Tailwind, Alpine, Livewire, Laravel ) and use Filmanetphp for rapid panel development. I've also built many custom WordPress plugins. AI augmented - I'm a claude code power user and Cursor is my IDE for fine tuning. I tend to have 2-3 AI coding assistant processes running at any given point in my workflow - for maximum productivity. I closely review generated code and pay tons of focus when/where needed. From one of my favorite reviews I've received here on Upwork - "I've never met such a skilled developer. I mean, we are talking world-class ladies and gentlemen! You are not going to discover a better developer anywhere else." -- Some recent projects; - Built a multi-tenant SaaS for scout troops, AI chatbot with API access to all the troops data like upcoming events, scout advancement progress, etc - Build an app that has a csv importer for companies, calls multiple APIs for gathering data about key people and uses LLM to generate targeted sales copy - Built an API for voice to text transcriptions to run on a local network machine - Setup local network open weights models for unlimited use without paying for tokens - Built a sales management system for an auto insurance dealer ( so his sales people could login, enter a sale, and commissions could also be tracked ) - Built a social network type app with courses and badges, a bit like linked in but focused on fast moving and fast shifting careers. - Built a platform for folks to promote their favorite business' and earn commissions. - Built a custom web application billing system for a contractor / sub - contractor service provider company that has dashboards for clients and vendors with billing and split payments so contractor earns platform fee. -- - "Joseph was kind, responsive, quick, direct, and receptive to feedback. If you have worked with other developers, you know how rare this is, and how important it is to find someone who truly cares about the quality of work they provide. He couldn't have been better to work with." "Joe is incredibly talented and an absolute pleasure to work with. He is our go-to guy for a variety of challenges and we have full confidence" "I really enjoyed working with Joseph. He was honest and direct with his communication. He didn't try to oversell his services. It was all about just getting the job done, doing it well, and communicating with me about what was going on throughout the whole process." - --- Ultimately, good web dev service consists of not only coding, but also translating your needs into solutions, communicating effectively, training you how to use the software, and giving you confidence along the way. I'm here for my clients to find their way through web dev projects. If there is anything I can't do, I'm happy to handle bringing in help on that specialty. I will be honest with you. My skills include but are not limited to; - Web App development - Laravel development - WordPress plugin development - Stripe integrations - Payment gateways - E-commerce - API integrations - AI automation I'm able to help with system design and database design, user experience, and optimization. I offer functionality consulting and can help prepare detailed requirements documents for larger projects. I do my best to provide ideas to solutions - when there is no clear path, a bit of research and some creativity can go a long way. Contact me to discuss your needs!
