Telecommunications Network Designer with more than 15 years of experience in FTTH, GPON, XGS-PON, and outside plant network design. I specialize in developing and updating construction-ready HLD and LLD packages for fiber optic networks using IQGeo, AutoCAD, and GIS platforms. My experience covers the complete ODN lifecycle, including feeder and distribution architecture, PFP and serving-area planning, centralized splitter configurations, fiber cable sizing, splice closures, handholes, flowerpots, fiber serving terminals, customer drop pathways, and aerial and underground routing. I have hands-on experience designing microtrench, trench, and HDD/bore routes; reviewing ROW and utility conflicts; applying municipal construction standards; and preparing designs for efficient and practical field construction. I also support design revisions, redlines, as-built updates, BOM validation, splice plans, optical-loss budgets, material reports, and QA/QC. My technical toolkit includes IQGeo, AutoCAD, QGIS, ArcGIS, Google Earth, Excel, Slack and Microsoft 365. I have worked remotely with U.S.-based engineering and project management teams, delivering accurate designs under defined milestones, schedules, and quality requirements. The successful design of FTTH projects can result in numerous benefits, including: -Minimize costs and optimize return on investment (ROI). -Maximize network capacity and scalability. -Reduce project delays and minimize backtracking. -Ultra fast Internet speeds. -Improved reliability.-Infrastructure prepared for the future.-Improved user experience.
