Laravel React & Next.js Developer | SaaS, Marketplace, AI Chatbot

I help founders and teams get unstuck when a Laravel, React, or Next.js SaaS product needs to move forward without breaking what already works, whether that's stabilizing an existing SaaS built on Laravel, building out a marketplace with Laravel and React, adding an AI layer to a SaaS platform that already has users, or picking up a Laravel, React, or Next.js codebase someone else left behind. Top Rated on Upwork, 100% Job Success, $30k+ earned. Where I fit best: ✔ Laravel backend development, API integration, and database design ✔ Stabilizing, auditing, and extending existing Laravel and Next.js SaaS platforms ✔ Two-sided marketplaces built with Laravel, React, and Next.js: listings, lead management, and payment gateway integration ✔ AI chatbot and OpenAI API integration inside existing SaaS products ✔ React / Next.js dashboards, admin panels, and internal tools ✔ Bug fixing, performance work, and ongoing maintenance across Laravel and Next.js codebases ✔ Full-stack builds combining Laravel, React, and Next.js when the project needs both ends done right I'm comfortable working alongside AI-assisted workflows (Claude Code, Cursor). I use them to move faster, but I still read and understand every line that goes into your project before it ships. What clients say: "Kezia produces very high quality work and is committed to successful outcomes." client review, SaaS code review project "Kezia is genuinely impressive... on time, reliable, very proactive, and goes above and beyond the brief." client review, ongoing project I ask questions to clarify tasks and scopes, and I give daily progress updates so you're never wondering where things stand. If something outside scope needs fixing, I flag it and ask before touching it, not after. If you have a Laravel, React, or Next.js project that needs a steady hand, whether it's an existing SaaS, a marketplace build, or an AI feature you want done properly, send me the details and I'll tell you honestly how I'd approach it.
