Career Trajectory

Professional Evolution

Architecting Hybrid AI Ecosystems

With nearly 5 years of engineering evolution, I specialize in fusing robust system architectures with hyper-responsive, intelligent interfaces. My expertise lies in bridging the gap between raw data and human experience—leveraging Node.js, Python, and Next.js to build scalable digital nervous systems.

I don’t just write code; I engineer Voice-First Experiences (TTS/ASR) and Generative AI solutions that listen, think, and respond. Driven by clarity and velocity, I empower teams to ship complex features that feel effortless to the user.
