• Designed and implemented optical network topologies to simulate and validate project-specific scenarios, ensuring transmission performance and reliability.
• Operated and maintained DWDM/OTN transmission infrastructure (e.g., ROADM/WSS, EDFA/Raman amplifiers) and integrated optical transceivers (e.g., SFP+, QSFP, CFP2). Performed functional and stability tests, troubleshooting, and quality control (QC).

• Investigated the evolution of mobile networks through 5G, focusing on the emerging Open RAN (O-RAN) architecture and evaluating Software-Defined RAN (SD-RAN) as its implementation solution.
• Deployed RAN Simulator utilizing the O-RAN E2AP standard to model multiple Centralized/Distributed Unit (CU/DU) nodes and Radio Unit (RU) cells, evaluating network performance.

• Applied the Method of Moments (MoM) with Point Matching and Galerkin formulations to analyze parallel and coplanar plate capacitors, computing charge distributions and capacitances.
• Evaluated mutual capacitance and proximity effects in coupled parallel-plate capacitors using a block-matrix MoM formulation.

• Modeled shielded microstrip lines and rectangular waveguides using Finite Difference Method (FDM) with SOR and RQI solvers to compute characteristic impedances and cut-off wave numbers.
• Modeled open microstrip lines via MoM with Point Matching and adaptive mesh refinement to determine characteristic impedances.

• Analyzed TE_z mode propagation and dispersion characteristics in symmetric and asymmetric planar slab waveguides.
• Realized Self-Phase Consistency (SPC), Coefficient Matrix (CMM), and Transmission Matrix (TMM) Methods to derive phase constants and dispersion diagrams.

• Simulated beam splitters, Bell states, and the Hong-Ou-Mandel effect using the IBM Qiskit framework.
• Implemented and analyzed quantum circuits to model the quantum teleportation protocol and a Mach-Zehnder interferometer.

• Evaluated BER in UAV-based Free-Space Optical (FSO) links under diverse atmospheric turbulence conditions.
• Simulated Soliton and Gaussian pulse propagation in optical fibers via the Split-Step Fourier Method (SSFM).
