Zentact
Embedded payments portal
Senior Software Engineer · Payments SaaS
Whitelabel merchant portal for embedded payments — onboarding, dashboards, and operational tooling beside an Adyen flow, rather than a from-scratch payments stack.
01Problem
SaaS platforms needed merchant-facing payments operations — onboarding, reporting, branded portal — without spending a long custom build assembling that surface themselves.
02Selected contributions
Built user-facing product interfaces for Zentact’s managed payments SaaS and contributed technical direction and backlog sequencing on the React / tRPC / Prisma path. Card-data handling, PCI controls, and processor integrations are not claimed.
- User-facing product interfaces for the payments portal
- Work on the tRPC / Prisma / PostgreSQL delivery path
- Technical direction and delivery sequencing on a short senior engagement
03System context
React UI talks to Node.js over tRPC. Prisma maps the domain onto PostgreSQL. The product is hosted on Google Cloud. Public marketing figures (build-vs-buy cost, uptime SLAs, third-party case-study volumes) are not used as personal results.
