You will get AI Project setup to help you build clean, testable, stable code.
Project details
Most developers point AI at a tangled, untested codebase and hope for the best it writes plausible code that quietly breaks things. I do the opposite. I restructure your project into a clean hexagonal (ports & adapters) architecture, build the unit-test suite you never had, and set up an AI workspace with guardrails Claude actually follows. The result: business logic separated from framework code, a safety net that catches regressions, and an environment where AI becomes leverage instead of a liability.

About Joshua
Web Developer
Hammond, United States - 10:55 pm local time
What I do most:
Legacy modernization — moving old apps (including WordPress) onto modern stacks without losing URLs, data, or SEO, and without downtime.
Payments — Stripe integrations from single charges up to full Stripe Connect marketplaces: autopay, application fees, webhooks, chargeback handling.
SaaS builds — multi-tenant apps from scratch: auth, billing, admin panels, calendar sync, automated notifications.
Native mobile — iOS and Android, including offline-first apps with multi-device sync.
AI integration — practical things like data cleanup, document-to-form prefill, and in-app assistants.
Security & accessibility — external security reviews and WCAG 2.1 AA fixes.
A few things I've built end to end: migrated a 15,000-recipe site off WordPress to Next.js with cleaned-up legacy data and a Stripe print-on-demand store; a Stripe Connect platform where independent sellers take their own payments, with two-way Google Calendar sync; a native offline-first POS with multi-device sync and tax-ready reporting. Case studies on request.
Good fit for legacy systems that need rebuilding, new products that need to ship, or integrations (payments, calendar, AI) that have to work in production. Not a fit for one-off scripts or template work.
I'm new to Upwork but not to the work: six years of production code behind me, and I'll send case studies and references up front. Tell me what you need built or fixed and I'll let you know if I'm the right fit.

File Delivery
I deliver a set of files tailored to your project that keep your AI coding tools in line so you build software that's easy to maintain, fully tested, simple to extend, and far more stable. You install them at the root of your repo and start building.
