What I'm looking for

I seek backend-focused roles where I can design scalable realtime systems, own architecture decisions, work with observability practices, and grow toward technical leadership.

I am a backend-focused full stack developer with 3+ years building scalable web applications and real-time systems across fintech, e-commerce, and gaming. I transitioned from a Chemical Engineering background and apply a structured, problem-solving approach to architecture, tool evaluation, and reliable delivery.

My work includes designing a headless e-commerce architecture with a custom Next.js frontend, building a WebSocket-based real-time multiplayer lobby with queue-based expiry using BullMQ, and integrating Meta WhatsApp Business Cloud API with secure webhook workflows. I independently own architecture decisions and focus on scalability, maintainability, and observability.
