You will get a crypto on/off-ramp web app with PIX and admin panel


Project details
I will build a crypto on/off-ramp web application with PIX (and/or any other instant payment method for other countries), admin visibility, and scalable fintech architecture. This project is ideal for startups, fintechs, exchanges, and digital asset businesses that need a serious transactional platform instead of a generic template.
The solution can include user onboarding, asset buy and sell flows, payment journey design, transaction status tracking, admin dashboard and operational visibility, wallet/balance modules, and backend structure ready for future integrations.
This project is designed for real fintech execution, with strong focus on transaction clarity, operational control, security, and user experience. Depending on the selected package, I can deliver a technical blueprint, a functional MVP, or a more production-ready web application.
Typical use cases include crypto on/off-ramp platforms, digital asset payment operations, treasury and payout flows, escrow logic, and admin/backoffice transaction control.

About Cristiano
Head of Product & Technology | Digital Payments, Fintech, DeFi & Web3
Bertioga, Brazil - 5:55 pm local time
I’m a product and technology leader with 17+ years of experience building and scaling digital platforms across fintech, healthtech, SaaS, Web3, digital assets, and payments.
My career has been built around turning complex business, operational, and technical challenges into real products. I’ve led product strategy, roadmap, platform design, cross-functional execution, and business expansion initiatives in environments ranging from startups to enterprise-facing digital businesses.
More recently, I have been leading a crypto/BRL on/off-ramp payments initiative focused on transaction flows, payment journeys, and digital financial operations. I am also leading the development of a product for a DAO (Decentralized Autonomous Organization), a platform initiative centered on P2P trading, crypto escrow intermediation, and peer-to-peer transactional logic based on DeFi. These initiatives reflect the kind of work I identify with most today: products where payments, user journey, operational reliability, and business model all need to work together.
Before that, I led product and technology at BYOS Health, worked on financial and tokenization initiatives at Neuro, and supported advanced digital asset platforms at Foursys, including Token4You, an RWA tokenization platform that attracted the interest of a top-3 Brazilian bank back in 2023/24.
Since 2016, I have been deeply involved in Web3, crypto infrastructure, tokenization, digital payments, trading environments, and asset operations. I also bring international exposure across the U.S., Caribbean, and Latin America, including work related to product expansion, business structuring, and regulatory-oriented digital operations.
What I bring most consistently is the ability to connect strategy, execution, technology, operations, and business development — especially in complex or fast-moving environments where clarity, ownership, and product judgment matter.
Main areas of interest:
• Head of Product / Product leadership roles
• Fintech and digital payments
• Web3 infrastructure and tokenization
• On/off-ramp and escrow models
• Strategic partnerships and business expansion
• Product-building in complex digital environments
Very comfortable with:
Node.js/NestJS, TypeScript, PostgreSQL, React, React Native, Supabase, REST APIs, API integration workflows (e.g. Stripe, WhatsApp third party APIs, such: W-API, Z-API). PWA (Progressive Web App) dev. No-code AI-workflow automations and refinements (Bubble, Make, Lovable). Jira, Asana, Trello, Miro, Figma, GitHub, Postman, Power BI, identity/authentication flows, cloud-based hosting (AWS, GCP).
Fluent English (read/written/spoken) and Spanish (spoken fluently). Native Portuguese.
