What I'm looking for

I'm looking to build secure, scalable backend systems and REST APIs, with opportunities to deepen my Node.js, MongoDB, real-time, fintech, and system-design experience.

At Cyvanta Tech Quantum, I build backend APIs for products including Bonza, an MLM and cashback platform, and a social media application.

I architected Bonza's multi-tier referral logic, member validation, level-upgrade triggers, digital wallet workflows, cashback engines, withdrawal approvals, and transaction logging. I also improved dashboard and referral-tree performance through MongoDB aggregation and strategic indexing.

For a social media API, I developed JWT-based email and phone authentication, private-account workflows, blocking and muting controls, Cloudinary streaming uploads, Socket.io real-time updates, and automated 24-hour content deletion using TTL indexes.

I'm a 2025 Computer Science graduate focused on building secure, scalable REST APIs with Node.js, Express.js, TypeScript, and MongoDB.
