<h2>About Me</h2>
<div class="about-panel fade-in shadow-fade">
<div class="about-content">
<p>
I am a compiler engineer at AMD, UK, currently part of the HPC
compiler team for the Frontier supercomputing project. I work on
the new llvm‑flang driver for Fortran and on device code
offloading support for the OpenMP dialect in MLIR.
</p>
<p>
My interests lie in compilers, program analysis, formal
verification, and SAT solvers. I attained my master’s in Computer
Science & Engineering at IIT Hyderabad under
Prof. Saurabh Joshi in the field of software verification, and
worked with Prof. Ramakrishna Upadrasta on improving compiler
optimizations.
</p>
<p>
When I’m not coding, you can find me losing at DOTA 2,
staring at my fish tanks, or giving pats to Simba (OTRB). I’m also
