Who am I?

class Nehal:
    role        = "Aspiring AI & Data Engineer"
    university  = "Manipal Institute of Technology, Bengaluru (2023–2027)"
    cgpa        = "8.06 / 10.0"
    building    = ["ML pipelines", "adaptive auth systems", "forecasting models"]
    beyond_code = "Charter President @ MAHE Bengaluru Toastmasters 🎤"
    fun_fact    = "Scored 99/100 in CS boards — the bug bit early 🐛"

I like building things that sit at the intersection of data, intelligence, and real-world impact.
Whether it's forecasting Cisco's supply chain or detecting financial fraud with Graph Neural Networks —
if it involves a model and a problem worth solving, I'm in.
