Upwork is where I prefer to start with a new client, and where a good share of my React Native, web and AI work for founders and agencies has run. This page gathers what the profile shows, the reviews, the contracts and the projects behind them, so you can decide before you message me.
“Very knowledgeable and dependable”
“Ramón es un profesional con mucha experiencia en desarrollo de apps. Siempre ayuda con visiones adicionales a lo solicitado y tiene alto compromiso con el desarrollo”
Reviews are left by the client when a contract ends and I can neither edit nor hide them. All seven, including the ones without a written comment, are on the profile.
Titles are summarized in my words and client names are left out. The original posting, the dates and each review are on the profile.

Yes. Ramón Chancay is a Top Rated Plus freelancer on Upwork with identity verified, more than $50K earned on the platform and 14 completed jobs building React Native apps, web platforms and AI products. You can send him an invitation from his profile at upwork.com/freelancers/devrchancay, or message him directly first and move the contract to Upwork afterwards.
For a first project he recommends Upwork. On fixed-price contracts the money stays in escrow until you approve each milestone, on hourly contracts every hour is logged, and if there is a dispute Upwork mediates. Clients who already know how he works sometimes move to a direct contract; the way of working is the same either way.
It is the badge above Top Rated. Upwork awards it to freelancers with consistently high client satisfaction, a sustained earnings history and larger or longer contracts, and it recalculates it periodically. Ramón does not apply for it or control it; the platform assigns it from his contract history and client feedback.
Both. Of his 14 completed jobs, 9 were fixed price and 5 hourly. Fixed price suits a scope that can be written down, like an MVP or an app launch; hourly suits ongoing work and production rescues where the problem has to be found first.
Mostly React Native apps for iOS and Android (MVPs, launches, production stabilization, voice features with Whisper and TTS), full-stack web work with React, Next.js and Node.js, urgent debugging of existing apps, and AI architecture. He works with founders and agencies in English and Spanish.
If you already have a job post, send me an invitation and I will reply the same day. If you would rather talk first, tell me in two or three lines what you want to build and we can open the contract on Upwork once the scope is clear.
