Hi, my name is
Vijayan Subramaniyan
Technical Program Manager | AI/ML Enthusiast
I build harmonious teams and catalyze innovative culture. With 20 years at TCS leading global ATM banking transformations, I now focus on bridging the gap between enterprise software and AI/ML innovation.
01.About Me
With two decades of experience at **Tata Consultancy Services (TCS)**, my journey has been defined by a relentless pursuit of excellence in Technical Program Management across the globe—from Singapore and Mexico to the US and India. I’ve had the privilege of leading multi-million dollar ATM banking contracts, managing over 250 annual deployments, and spearheading critical migrations for the world's leading financial institutions.
But beyond the metrics and the scale of operations, my true passion lies in **AI/ML innovation** and **building harmonious teams**. I believe that technology is most powerful when it empowers people. As a "Contextual Master" at TCS, I thrive on bridging the gap between legacy enterprise systems and the transformative potential of Generative AI and Machine Learning.
My transition into the AI/ML space wasn't just a career pivot; it was a realization that the data-driven future requires both technical rigor and empathetic leadership. Whether I'm predicting wind turbine failures or optimizing food hub performance, I approach every challenge with a focus on "What I learned the hard way"—valuing failure as the most honest teacher of progress.
