SinerPay.
One company's tool, now a payments platform.
Named with permission. A long-running product we've built and continue to evolve; specifics are kept general by agreement.
SinerPay is a platform for secure remote payments and customer interactions — Pay-by-Link across SMS, WhatsApp and more. It began as a small, specific tool for a single company and grew into a general-purpose product, evolving across five versions as its client base and use cases expanded.
We shape SinerPay's technical direction and roadmap alongside the client. The current chapter is version 5 — a ground-up rebuild that folds years of accumulated client needs into one coherent product. We moved it to a Turborepo monorepo, brought the API inside Next.js, and rebuilt it on an asynchronous architecture so heavy work runs in the background instead of making anyone wait. The v5 transition took about six weeks; the product is in continuous development.
SinerPay runs in continuous production and processes thousands of transactions a day, helping its clients collect at real scale. Version 5 is the cleanest the product has ever been — and it keeps evolving with the business behind it.
A companion app that turns a platform's scattered, one-at-a-time features into single cross-cutting workflows.
