What I'm looking for

I'm looking to build secure, scalable backend products where I can own architecture, APIs, data modeling, CI/CD, and production delivery while working with a small, high-leverage team.

At Kasroad, I own backend architecture and delivery for two products, covering data modeling, REST APIs, authentication, background processing, and deployment. I use AI coding agents to accelerate delivery while personally reviewing every production change.

I've built queue-driven integrations, horizontally scaled Node.js infrastructure, OAuth 2.0 and passkey authentication, and multi-tenant SaaS data isolation. My work includes a non-VoIP OTP leasing platform built around BullMQ and Redis Sentinel, plus XchangeCards, a white-label e-commerce SaaS with referral and commission tracking.

Before Kasroad, I delivered maintainable backend systems as a freelance developer across Node.js, NestJS, Express, Laravel, and Spring Boot. I take ownership of API design, security review, CI/CD, documentation, and clean handover.
