Andrei Sebastian Aguirre
@andreisebastianaguir
I keep POS systems, payment gateways, and retail networks running during critical incidents.
ColombiaWhat I'm looking for
I support point-of-sale systems, payment gateways, and network infrastructure for high-volume retail and hospitality businesses. At NYPOS, I troubleshoot critical outages, from network drops during peak hours to corrupted database transactions.
I've led remote deployments across 200+ terminals, optimized UberEats and DoorDash order integrations, and built recovery protocols that restore merchant operations quickly. I translate technical fixes into clear steps for non-technical users using SQL, TCP/IP, PCI-DSS, EMV terminals, and remote-support tools.
