We present a framework for constructing Generalized Parton Distributions(GPDs) using holographic QCD in the large $N_c$ limit, with a focus on low-xand finite skewness. Our approach utilizes holographic amplitudes for exclusiveelectroproduction processes to extract the spin-j conformal (Gegenbauer)moments of GPDs, which are then evolved to higher resolution scales using QCDevolution equations. Our evolved GPDs (reconstructed from their evolvedconformal 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 theexisting experimental data. Our GPDs provide detailed information aboutpartonic distributions and are useful for future experimental studies andglobal data analyses.
