Hello! My name is Jonathan, I'm a solo contracting professional with a passion for turning ideas into impactful digital solutions. My specialties are HubSpot tools/development and python django, flask applications. I like to diagram sales pipelines and app features, and have a lot of experience building both. I'm great with the HubSpot API, Chat GPT API, python scripting, data science, HTMX, and a host of other odd skills that surprisingly work really well together. I can integration HubSpot CRM commincation and LLM features into your Sass application. I make a great consultant too, for applications where the code base might be outside of my skill set. If you are looking for a HubSpot website developer, take a consultaion with me first. I have a decade of experience developing websites specifically for the HubSpot CMS. I've been through every stage of advancement with their theming environment. Hundreds of HubSpot websites contain my code. But HubSpot has advanced quite a bit and development isn't as expensive or time intensive as you might think. Let me show you some tricks, as a consultant, to knock your website out without all of the overhead. I use Upwork's hourly timer with screen shots and activity tracking. I find it to be a great tool for transparency and communication. I also use AI to speed up certain tasks in my workflows. I'm solutions oriented and I like to move fast. You can see I have a couple of contracts open, a lot of my current contracts are long-term on-going as-needed relationships with clients that just ping me when they need something. Some days can get a little busy, but if you hire me you'll figure out why clients keep me around. For Django/Flask/Python jobs, I am an intermediate developer but I have worked on several very large projects. I'm not great with AWS, I know my way around Digital Ocean. I understand DevOps and Agile, I'm happy writing docs in Confluence or Notion, and I'm not scared of Jira, or any kanban project mangement system. I specialize in feature development in django/htmx, can work in flask, I'm not a fan of javascript heavy stuff. If you need an application prototyped from scratch with useable features I can knock out a solid user ready app in less than 100 hours. You'll need to bring your own scalable server environment. Lastly, technical SEO for websites is something that I enjoy. I'm great at discovering and fixing app and HubSpot SEO errors with the document structure of web pages. Let's Chat: I really am just happy to hop on a call, so don't hesitate to reach out if you, your team, or your organization have any questions.

If your data is stuck in the wrong system, in messy files, or behind an awkward API, I can help. I turn complex data problems into working systems and usable deliverables. I help clients move data between platforms, automate manual work, clean up unreliable exports, and build workflows that save time and reduce errors. Whether the deliverable is a program they can keep using, or a clean CSV, Excel file, report, or database, I can make it happen. Most of my work is API integrations, ETL pipelines, backend automation, data processing, and data migrations. I'm at my best when the problem is not clean or perfectly defined. I'll solve that problem first. I build data workflows that are meant to hold up in real use. I work with complex APIs, big JSON or XML data files, elaborate schema, folders full of CSV and Excel files, and large datasets where correctness matters. The result is a cleaner dataset, a dependable program, or a responsive and well-designed workflow. If you need a dependable program, a solid new system, or a clean final dataset, I can help.

If your app is broken, behind schedule, or stuck with bugs you canโ€™t diagnose, I can help. Iโ€™m a senior full-stack developer with 30+ years of experience fixing, stabilizing, and finishing production systemsโ€”especially React, Node.js, APIs, and databases. Iโ€™m often brought in when: โ€ข A project is partially built but stuck โ€ข A previous developer disappeared โ€ข Bugs are blocking launch โ€ข APIs or integrations arenโ€™t working My focus is fast diagnosis, clear communication, and shipping fixesโ€”not rewrites. Iโ€™m a hands-on developer with 35 years of experience delivering production software across web, backend, and infrastructure systems. In recent work, Iโ€™ve been building and fixing applications using React, Node.js, MongoDB, and modern cloud environments. I also work with Web3 systems when needed, including Ethereum and Solana smart contracts, token integrations, and wallet-based workflows. With experience across many languages and platforms, I adapt quickly to the problem at hand and focus on getting things working reliably. Common fixes I handle: โ€ข API integrations that fail, timeout, or return incorrect data โ€ข Third-party API auth, webhooks, and data sync issues โ€ข React rendering, state, and performance issues โ€ข Node.js / Express backend errors and crashes โ€ข MongoDB schema, query, and data issues โ€ข Finishing half-built MVPs Iโ€™m available for short-term fixes or ongoing support.

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!
