THE CHALLENGE

Creating Structure for Complex Carbon Transactions

EcoRegistry needed a payment solution for multiple carbon credit transaction types—registration, certification, transfer, and more. Their team also lacked tools for commercial oversight and reporting. Manual workflows were slowing them down, especially when managing receipts and transaction visibility.

INITIAL STATE

OUR SOLUTION

A Stripe-Integrated Platform for Scalable Carbon Management

Requirements

Centralizing Carbon Payments

We scoped and defined a payment engine capable of handling certification, registration, maintenance, and retirement fees—along with user registration, transaction logging, and reporting capabilities.

Application

Built Fast with TypeScript + NextJS

Using TypeScript, NextJS, and Stripe, we delivered secure payment flows, generated receipts, and added idempotent transactions for reliability. We also developed a Shopify plugin for carbon offsetting at checkout.

Prototype

Functional Delivery in Eight Weeks

We completed 61 user stories and delivered on time with 98% of features accepted bug-free. Key modules—including payment, receipts, and reports—launched at 100% scope completion.

DELIVER STATE

CUSTOMER FEEDBACK

A Seamless Launch for a Mission-Driven Platform

EcoRegistry's Product Owner approved the final product with satisfaction. Our team—led by Ana Vásquez with support from developers and designers—called it a “learning and fulfilling project.” Together, we automated core operations so EcoRegistry could focus on protecting the planet.

Camila, I really appreciate the extra efforts you have made on the app this months. I feel you went above and beyond to create scalable solutions consistent with the existing design. You achieved far more than I thought was going to be possible going in, and the new version of the app gives me a lot more confidence to go into sales mode.

I've dm'd you a gift card code for Amazon as thanks.

Every Mother

A quick shoutout to Melt, it's been several months now and it's clear that our new dev team has been crushing expectations all around. Shoutout to Camila who has been killing it on uhc and flex, especially on uhc, which basically gave us documentation for a platform that only exists in their dreams. Considering she's doing this without a test environment which uhc guaranteed us, Camila has put in a lot of elbow grease to make this implementation seemingly smooth sailing. Additional shoutouts to Yuli and Miguel who both have stepped into the shoes of past RPS teammates to support internal operational functions as well as put the pedal on the gas to churn out product developments. Lastly to Yulys and Austin who have seamlessly taken in the project reigns from Natali alongside the rest of Melt. Special shoutout to Sebastian who is always helping from the shadows but more recently has been contributing a great deal of effort to help resolve some longstanding revenue analytics issues. So thank you to our Melt teammates for being able to hop in immediately, helping EM put some very big pieces into place at this critical moment of our company's growth! 🎉🎉
