What I'm looking for

I'm looking to build production backend and full-stack systems where I can own API design, secure payment workflows, data modeling, performance, and scalable product features.

I've built KashyBee from scratch as the solo founding engineer, delivering 270+ production APIs, 75+ relational models, wallet workflows, settlements, merchant operations, and multi-panel administration.

At ZAPTA Technologies, Planlab Solutions, and WebWrite Inc., I've shipped fintech, SaaS, real estate marketplace, NFT marketplace, and cross-border payment systems. My work has supported thousands of daily transactions, 10K+ daily API requests, 300K+ active users, and 500+ concurrent real-time connections.

I focus on API design, relational data modeling, secure authentication, RBAC, payment integrations, and database performance using Node.js, NestJS, TypeScript, PostgreSQL, Prisma, Redis, React.js, and Next.js.
