What I'm looking for

I'm seeking remote opportunities building scalable products, particularly in fintech, SaaS, and high-growth environments, where I can contribute to backend architecture, reliable payment systems, and technical decision-making.

I build backend systems for payment processing, billing, and financial operations, with a focus on scalable APIs that support revenue and subscriptions.

At Pagah, I develop payment-processing backends, maintain financial and third-party integration APIs, and optimize high-demand endpoints through Redis and SQL tuning. Previously at Bagy, I supported a high-traffic e-commerce platform through peak events such as Black Friday.

I'm experienced with Node.js, TypeScript, Laravel, AWS, Redis, Docker, and SQL, and I’m growing toward technical leadership through system design, architecture, and decision-making.
