𝗔𝗕𝗢𝗨𝗧 𝗠𝗘
I am a React developer who has spent years turning complex SaaS interfaces into clean, fast, predictable products. My focus is the layer where React, TypeScript, and Next.js meet real business goals: clearer navigation, faster load times, and React interfaces that reduce support tickets instead of creating them. I care about the details users feel but rarely name, the moment a screen responds instantly or a flow simply makes sense.
𝗪𝗛𝗔𝗧 𝗜 𝗗𝗢
▸ React development. Component-driven React applications built with TypeScript, maintainable architecture, and predictable state.
▸ Next.js development. App Router, React Server Components, ISR and SSG, middleware, and edge rendering.
▸ SaaS dashboards and web apps. Multi-step flows, data-heavy tables, and settings panels made fast and intuitive in React.
▸ UI UX implementation. Figma turned into pixel-accurate, responsive React frontends with accessibility and clean markup built in.
▸ React performance. Render optimization, code-splitting, and Core Web Vitals tuning so React pages load fast and stay stable.
▸ Frontend integrations. React frontends connected to REST and GraphQL APIs, headless CMS, and Stripe or Shopify payment flows.
▸ React component libraries. Reusable React component kits documented in Storybook so your team ships consistent UI faster.
𝗦𝗘𝗟𝗘𝗖𝗧𝗘𝗗 𝗥𝗘𝗔𝗖𝗧 𝗪𝗢𝗥𝗞
▸ Spinify, B2B SaaS: redesigned the web app menu structure, separating product and settings navigation so users could find what they needed without hunting.
▸ AI industry product: built a React and Next.js Progressive Web App with a responsive, production-ready UI.
▸ B2B SaaS marketing site: full UI UX design and React frontend build.
▸ Stale product revamp: rebuilt a tired front end into a modern, responsive React interface under a tight deadline.
▸ React and Vue feature work: shipped frontend features across a mixed React and Vue codebase for an existing product team.
▸ Medical and travel websites: pixel-perfect Figma to React layouts, responsive across every device.

SaaS founders, product teams, and agencies who need a reliable React developer as a frontend partner, not just a pair of hands. Whether you are redesigning an existing web app, shipping a new React product UI, or cleaning up a React frontend that has grown messy over time, I plug into your workflow and communicate clearly throughout. Comfortable working solo or alongside an existing design and backend team.
𝗠𝗬 𝗣𝗥𝗢𝗖𝗘𝗦𝗦
1. Discovery: I review your goals, your current React codebase or designs, and define what success looks like before writing code.
2. Architecture: React component planning, state model, and delivery milestones agreed up front.
3. Build: clean React implementation with TypeScript, delivered in small, testable increments.
4. QA: responsive, accessibility, and performance checks on every React screen before handoff.
5. Handoff: readable React code, clear documentation, and a frontend your team can keep maintaining.
𝗥𝗘𝗔𝗗𝗬 𝗧𝗢 𝗦𝗧𝗔𝗥𝗧
Send me a message with a bit about your product and what you are building. I will reply within a few hours with honest thoughts on the React frontend work involved and a realistic estimate for the React or Next.js build you have in mind.
