  We present a framework for constructing Generalized Parton Distributions
(GPDs) using holographic QCD in the large $N_c$ limit, with a focus on low-x
and finite skewness. Our approach utilizes holographic amplitudes for exclusive
electroproduction processes to extract the spin-j conformal (Gegenbauer)
moments of GPDs, which are then evolved to higher resolution scales using QCD
evolution equations. Our evolved GPDs (reconstructed from their evolved
conformal moments) are applied to analyze the electroproduction of $\rho^{0,+}$
and $\phi$ mesons, and we account for non-perturbative contributions in the
$s+u$ - channel using holographic QCD. The results compare well with the
existing experimental data. Our GPDs provide detailed information about
partonic distributions and are useful for future experimental studies and
global data analyses.
