💬 Responds within business hours, no excuses
🚀 What You Get
Whether you're launching a Next.js Supabase MVP, rescuing a tangled React NextJS codebase, or turning a Figma file into something real users can click on, you need a Next.js Developer who treats your product like it's their own. That's what you get here.
As a Front End Developer and Next.js Developer, every handoff leaves behind a codebase the next react developer can pick up and extend cleanly. Figma-to-code delivery, SaaS dashboards, admin panels, marketing sites, PWA, and storefronts are all handled with clean architecture and honest scope - whether the work is pure React NextJS on the front or a Next.js Supabase backend underneath.
💼 Recent Work
• Urbanouse - real estate platform built as a React NextJS app, Figma-to-production delivery for a multi-page catalog and agent-facing tools
• Real-time chat application - a react.js front end wired to a node.js Next.js backend with SocketIO (nextjs nodejs), powering live messaging and presence
• Production PWA - service-worker caching with workbox.js cut initial load from 2.7s to 2.4s; Lighthouse stays above 90
• E-commerce platform - a full stack next.js developer ecommerce build; cut build time from ~95s to ~50s via better tooling and minification
• Live React codebase - raised test coverage from 32% to 46% with modular Jest tests as the lead Next.js Developer on the project
• Commercial NDA work - React NextJS and Next.js Supabase features for established product teams across e-commerce and lifestyle niches
⚡ Tech Stack
Frontend: react.js / react js, Next.js, react typescript, nextjs typescript, JavaScript, tailwind css, shadcn/ui, Redux, React Query - a react nextjs frontend tuned for speed, with react next tailwind frontend structure and nextjs tailwind ux ui patterns baked in.
Backend & data: node.js, node, Express, nestjs (backend developer nest.js), SocketIO, MongoDB, PostgreSQL, nextjs firebase, and Next.js Supabase - including react next.js supabase postgres and react next supabase ai aws setups.
Full stack: full stack developer nextjs developer delivery, plus nextjs strapi and django nextjs seo when the content layer needs it.
Tooling: Figma, Vite, Jest, Git, Vercel, jamstack deploys.
Adjacent stacks: comfortable reading and migrating from vue / vue.js, angular, svelte, laravel, or php, plus legacy wordpress; can pair with a python developer and handle react native mobile or react native expo work when needed - focus stays web.
🔄 Working Style
Short projects get short timelines, bigger rebuilds get honest ones - no padded estimates, no surprise invoices. Written updates by default; live calls saved for when they actually move things forward. Every PR arrives readable, every commit has a reason, every question answered in hours, not days. A web product designer and ux designer sensibility runs through the work - interaction flow and front-end clarity - because interfaces that feel intuitive convert better than ones that just look correct.
🎯 Ideal For
• Founders who need a Next.js Developer or react js developer without the overhead of managing an employee
• Product managers hiring a react next js developer or Next.js Developer to pick up where the last contractor left off
• Agencies that need a full stack react developer or senior Next.js Developer to extend a small team without onboarding drag
• SaaS companies wanting a front end developer next.js saas setup from a Next.js Developer - a Next.js Supabase backend through to polished UI
• Shopify or wordpress front-end builds where the real work is clean React NextJS under the hood
• Teams consolidating from vue or angular into a React NextJS frontend - someone who can read old code and migrate it
• Startups adding AI features who want a Next.js Supabase build with a prompt engineer's eye on the integration
• Founders who saw a Pinterest-style feed or marketing site they liked and want it built right
• Anyone hunting for a web developer, software developer, or front end engineer who also handles Next.js Supabase architecture
💬 Let's Talk
Something here caught your eye - good, that's how it's meant to work. Drop a message with the project, the Figma, the repo, or a rough paragraph of what you're building. A real reply follows within business hours - scope, timeline, and a straight answer on fit, including whether a React NextJS build is right for what you need. No sales script, no ghosting.
