What I'm looking for

I want to own end-to-end delivery for production web apps—architecture, secure APIs, and responsive frontends—with strong CI/CD. I’m especially excited to build AI-powered workflow automation (n8n + Claude API) in a remote, cross-timezone team.

I’m a full-stack software engineer with 4+ years building and shipping production web applications end to end—database schema design, REST API architecture, OAuth 2.0 authentication, responsive React frontends, and CI/CD deployment.

I’ve built CRM, compliance, and marketplace platforms from scratch for clients across Australia, the USA, and Nigeria, including role-based permission systems and third-party API integrations. I’m comfortable owning a project solo, from requirements through build to handover, across remote and cross-timezone teams.

In my current role, I architected and built Kai’Mia CRM from scratch—designing a PostgreSQL schema with role-based access control, multi-tenant permissions, and automated invoicing workflows. I also shipped secured REST APIs with OAuth 2.0 and JWT session management, integrated the Brevo email API, and handled payment gateway webhooks over 1,000 monthly transactions.

I focus on delivery quality: writing technical documentation for independent operation by non-technical teams, and improving release velocity with CI/CD pipelines (GitHub Actions + Docker). I’m currently expanding into AI-powered workflow automation with n8n and the Claude API.
