You will get your AI-built app audited, hardened, and launched to production

Project details
You built something that works. I'll make it safe, fast, and ready for real users — then launch it on your own infrastructure.
AI coding tools are incredible for getting an app working. But "working on your machine" and "safe to put in front of real users" are two very different things — and the gap between them is exactly the part AI doesn't warn you about: security holes, exposed data, no error handling, performance that collapses under real traffic. Most people don't find out until something breaks or leaks.
That's where I come in. You bring me whatever you built. I pull the repo, we walk through it together so I understand what it does and how it works, and then I apply 20 years of web development experience to harden the edges, close the security gaps, tighten performance, and deploy it to production properly.
You end up owning a production-grade version of your app on your own infrastructure — plus a clear rundown of what I changed, why, and how to keep building on it. No black boxes.
Stack-friendly: Next.js, Tailwind/shadcn, Supabase, Clerk, Railway, Vercel, Upstash — and I'll work with what you've already got wherever it makes sense.

Navigation and Module Development
This is my second time hiring Jonathan, and I highly recommend working with him if you need a HubSpot sites expert.
Jonathan's attention to detail was invaluable. He took the time to discuss our implementation options and understand our goals, which shows in the final product. Once we had refined our scope, iterations were fast, and our feedback was implemented quickly through a few rounds of revisions.

About Jonathan
HubSpot Developer & Consultant | CMS, HubDB, CRM & Automation
98%
Job Success
Amarillo, United States - 4:51 am local time
98% Job Success, Top Rated Plus. Clients hire me as their "HubSpot sites
expert" and rehire me. I build and fix the technical side of HubSpot: CMS
websites, custom modules, HubDB-powered dynamic pages, landing pages, email
templates, and the workflow automations that save teams hours every week.
What sets me apart: I'm a real software engineer, not just a portal
configurator. I write custom code (HubL, JavaScript, Python/Django), build
custom objects and API integrations, and connect HubSpot to the rest of your
stack with Zapier, Make, n8n, or fully custom syncs. One client hired me to
build a complete Django application portal for their AI startup from scratch —
169 hours, delivered, 5 stars: "a spectacular engineer... instantaneous value."
Beyond HubSpot, I help SaaS teams stand up and standardize their product
operations — building and structuring product teams, defining repeatable
processes, and fleshing out products from concept to launch.
How I can help:
- HubSpot CMS and website development: custom themes, modules, HubDB, landing pages
- Sales process and pipeline consulting: lead, deal, onboarding, and support, built and automated
- Workflow automation and integrations: Zapier, Make, n8n, custom API
- Portal audits, cleanup, onboarding, and ongoing development support
- Custom development: Python/Django and Next.js apps that extend what HubSpot can do
- SaaS product and operations: standing up product teams, standardizing process, shipping products to launch
Recent clients: "his HubSpot development work was top-tier" - "an awesome
HubSpot expert who really knows his stuff" - "my second time hiring Jonathan."
Message me or book a consultation — tell me what's broken or what you're
building in HubSpot, and I'll give you a clear, honest plan on the spot.
Steps for completing your project
After purchasing the project, send requirements so Jonathan can start the project.
Delivery time starts when Jonathan receives requirements from you.
Jonathan works on your project following the steps below.
Revisions may occur after the delivery date.
Repo Handoff & Walkthrough
You send me the repository and we get on a call. I pull it locally and we walk through what you built, how it works, and where you're trying to take it. You know your app; I know what production demands — this is where those meet.
Triage & Assessment
I go through the codebase and map every gap between where it is and production: security exposure, data handling, authentication, performance, error handling, and structural fragility. You get a prioritized report and roadmap you keep.
