Christopher John Tolang

I am a full‑stack software engineer focused on TypeScript and robust API integrations, with hands‑on experience building connectors for platforms like Shopify, Klaviyo, Zoho, Microsoft Dynamics 365, and Temu. I deliver backend services, CI/CD workflows, and reliable integration solutions that support data synchronization, event triggers, and custom actions.

I've built offline‑first management systems and ticketing platforms using TypeScript, React/React Native, Node.js, Express, and MongoDB, integrating hardware like ticket scanners and supporting production deployments used by multiple transport terminals. I collaborate with distributed teams and prioritize code quality, uptime, and client satisfaction in fast release cycles.

My background includes full‑stack project work, a VSCode extension project for OAS customization, and experience with AWS, REST/GraphQL, and developer workflows (Git, Jira, CI/CD). I bring practical, product‑focused engineering to deliver scalable, maintainable systems.
