Milestones behind the engineering desk

How our low-level design practice took shape

Read the case files

2016 – First rack-level LLD for a Penang colocation hall

We started by mapping power and patch panels for a 120-rack floor. The client needed a clear cutover sequence, so we documented every circuit from the ATS down to the PDU outlet.

2018 – Fiber backbone plan for a 10 GbE core

Designed a 432-core trunk route between three server rooms, with dedicated pathways for intra-building links. The layout cut splice points by a third and gave the NOC a single reference drawing.

2020 – Cooling containment diagrams for high-density rows

Produced hot-aisle containment blueprints for 25 kW per rack loads. The drawings specified blanking panels, floor tile placement, and return air paths so the mechanical team could commission without guesswork.

2022 – Structured cabling standard for a multi-tenant build

Wrote the LLD for a 400-rack facility with separate zones for colocation and managed services. Every patch panel, ladder rack, and fiber cassette got a unique identifier that matched the field labeling.

2024 – Redundancy review for an existing server farm

Audited an older facility and reworked the LLD to separate A and B power feeds at the rack level. The updated drawings gave the operations team a safe sequence for swapping out legacy PDUs.

2025 – Current work: LLD templates for edge nodes

We are standardizing our drawing sets for smaller edge sites, so the same cable schedule and power plan can be reused across multiple locations without redrawing every detail.

Why Expertlld exists

We build low-level design blueprints for corporate data centers and server farms across Malaysia. Our work sits between the architect's concept and the crew pulling cable on site. Every diagram we deliver answers one question: how exactly does this infrastructure get built, connected, and maintained.

Precision before speed

An LLD blueprint is not a sketch. It specifies rack elevations, patch panel assignments, fiber trunk paths, and power distribution down to the outlet level. We take the time to verify every port and every route before the document leaves our office, because a wrong label on page 40 costs more than a day of rework on site.

Impact: fewer change orders during construction and a handover that matches the drawing set.
Design for the person holding the wrench

Our diagrams are read by cabling teams, commissioning engineers, and facility managers who may never meet us. So we write notes the way a senior engineer would explain them: clear callouts, consistent naming, and no assumptions about tribal knowledge. If a technician cannot follow the drawing without guessing, we redraw it.

Impact: shorter installation cycles and fewer interpretation errors in the field.
Redundancy is a habit, not a checkbox

Corporate server farms run on uptime. We map power feeds, cooling paths, and network uplinks with failure scenarios in mind. A single-line diagram should show what happens when a breaker trips or a fiber bundle is cut. We design so that the facility keeps serving traffic while the fault is isolated.

Impact: resilient infrastructure that survives component failures without panic.
Documentation that outlives the project

Most data center problems start months after go-live, when someone needs to add a rack or trace a circuit. Our LLD packages include as-built records, cable schedules, and labeling conventions that stay useful for years. We treat documentation as part of the infrastructure, not as an afterthought.

Impact: lower operational cost and faster troubleshooting for the facility team.
Local context, global standards

Malaysia brings its own constraints: tropical humidity, dense urban sites, and supply chains that do not always move fast. We design within those realities while keeping the drawings aligned with international telecom practices. The result is a blueprint that works in George Town and scales beyond it.

Impact: practical designs that respect local conditions without compromising on quality.

The engineers behind the blueprints

Our team has spent years inside corporate data centers, tracing fiber paths and validating rack layouts before a single cable is pulled. That field experience shapes every LLD we deliver.

Principal Telecom Engineer

Francisco Flores Mendoza

Francisco leads the LLD team with 14 years of infrastructure planning across hyperscale server farms in Southeast Asia. He has overseen more than 40 low-level design projects, from initial site surveys to final as-built documentation. His specialty is translating high-level architecture into cable-by-cable routing diagrams that installation crews can follow without guesswork.

Infrastructure Planning Lead

Isabel Sanchez Ortega

Isabel manages the technical documentation pipeline and quality checks for every blueprint that leaves our office. She spent six years coordinating fiber optic installations for corporate data centers in Penang and Kuala Lumpur, which gives her a practical eye for spotting routing conflicts before they reach the construction phase. She also trains junior engineers on our documentation standards.

Senior Network Architect

Daniel Reyes Lim

Daniel designs the logical layer that sits behind every physical layout. He works with clients to map out switch hierarchies, patch panel assignments, and redundancy paths, then hands those requirements to the LLD team. His background in telecom backbone projects means he knows where signal loss tends to creep in and how to design around it.

Site Survey Specialist

Mei Ling Tan

Mei Ling handles the on-site verification work that keeps our blueprints grounded in reality. She measures actual rack dimensions, checks ceiling void depths, and documents existing cable trays before we start drawing. Her field notes have caught more than a few discrepancies between building plans and what was actually constructed.

CAD Documentation Manager

Arif bin Hassan

Arif turns engineering decisions into clean, consistent drawing sets. He maintains our layer standards, symbol libraries, and revision controls so that every page of an LLD package reads the same way. His team produces the detailed floor plans, elevation views, and cable schedules that contractors rely on during installation.
