about

"I'm Nakarin Srita, a Solution Architect and Network Presales professional specializing in enterprise network design for clients."

My background includes network engineering, team leadership, customer requirement discovery, BOM/BOQ development, technical proposals, RFP/RFQ support, POC/UAT, vendor coordination, and project handover.

how I work
01

Start with real requirements.

I translate customer business and technical needs into solution direction before jumping into products or configurations.

02

Design for feasibility.

I build solution designs, BOM/BOQ, proposals, and scopes of work with delivery risk and implementation handover in mind.

03

Validate with the right people.

I coordinate with vendors, sales teams, technical teams, and customers to align licensing, product selection, POC, UAT, and solution fit.

04

Make handover clear.

I care about documentation, communication, and post-sales readiness so the solution can move from presales to delivery without ambiguity.
