01 / The Engineer

ABOUT ME

I’m Showvik Das, an OSP Design Engineer with over 2 years of experience in designing fiber optic networks. I specialize in AutoCAD, GIS integration, and creating construction-ready designs for both aerial and underground systems.

I’ve worked on large-scale projects exceeding $2.8M, focusing on permitting, BOM preparation, and as-built documentation. I'm passionate about optimizing workflows and have developed several AutoCAD LISP scripts to streamline OSP design processes.

I’m always eager to contribute to projects that shape the future of telecommunications infrastructure, ensuring robust, efficient, and reliable connections from the central office to the end user.

EXPERIENCE

OSP Design Engineer

Skarion
Aug 2024 – Present
  • Prepared detailed Bills of Materials (BOMs), calculating fiber quantities, conduit runs, and components with controlled contingencies, supporting $2.8M+ in project cost planning.
  • Led AutoCAD-based design efforts for large-scale XGS-PON fiber builds exceeding 400,000 feet, producing construction-ready drawings across multiple jurisdictions.
  • Assembled and submitted 50+ permit-ready design packages, incorporating ROW exhibits, alignment plans, and regulatory documentation to meet county and DOT requirements.
  • Executed design layouts for underground and aerial plant, including duct bank geometry, bore pit details, and pole attachment clearances per NESC guidelines.
  • Created and maintained splice documentation for F1–F4 network segments, defining splitter locations, fiber continuity, and port assignments.
  • Supported phased rollout of a residential fiber network serving 500+ households, delivering complete HLD/LLD plan sets across 40+ route-miles (1:32 splitter architecture).

AutoCAD Drafter

Skarion
May 2024 – Aug 2024
  • Created detailed designs for underground and aerial fiber routes, laying out conduit runs, handhole locations, and right-of-way clearances for distribution and backbone networks.
  • Developed and maintained drafting standards, templates, and SOPs to improve workflow efficiency and keep project deliverables consistent.
  • Improved CAD basemaps by adding geo-referenced mapping tools, making route planning easier and speeding up drafting work.
  • Performed thorough QA/QC checks on drawings, reviewing layer organization, alignment precision, and permitting criteria to ensure technical accuracy.
  • Worked closely with project managers and OSP engineers to resolve field issues, update redlines and keep as-built drawings accurate.

Workflow Automations

Auto_Road_Dimension Creator

Automated the creation of 6 clean, associative, aligned dimensions perpendicular to a road centerline at specified stations for infrastructure projects. Measures real-world distances between Edge of Pavement (EOP), Right-of-Way (ROW), and conduits on layers such as P_CONDUIT and P_CONDUIT_PARALLEL.

Workflow
Load file Run command Select source dimension Select centerline Click road sides Automatic dimensions
Auto_Block_Rotator

A simple and efficient tool to rotate blocks 180° around their insertion point without needing to select a base point or angle. Ideal for quickly flipping symbols such as trees, lights, signs, etc., enhancing drafting efficiency.

Workflow
Load file Run command Select block Instantly rotates
Parallel Conduit

Offsets lines/polylines/arcs by 3.0 units to create parallel conduit runs. Automatically places the new parallel object on the P_CONDUIT_PARALLEL layer, allowing for quick creation of side-by-side conduits.

Workflow
Load file Run command Select conduit Pick side to offset Repeat as needed
Conduit

Offsets selected lines/polylines/arcs by 10.0 units, specifically for fiber conduit routing. Automatically sets the new objects on layer 48 FOC with linetype scale adjusted to 25.0.

Workflow
Load file Run command Select objects Pick side to offset Objects offset
