WHAT I WORK ON
Engineering from packet path to platform.
Practical infrastructure work focused on reliability, security, performance, and clear troubleshooting paths.
Security & VPN
Firewall policy, secure segmentation, site-to-site tunnels, remote access, IKEv2/IPsec and WireGuard.
Performance & QoS
Latency analysis, bufferbloat mitigation, traffic shaping, queue design, DSCP and bandwidth optimization.
Monitoring & Troubleshooting
Packet-path analysis, logs, external monitoring, SLA validation, alerting and root-cause isolation.
Systems & Virtualization
Linux and Windows administration, Proxmox, services, containers, backups and infrastructure integration.
Automation & Documentation
Bash and PowerShell automation, repeatable configuration, operational runbooks and troubleshooting documentation.
SELECTED TECHNICAL WORK
Real troubleshooting. Measurable outcomes.
A few examples of how I approach performance, visibility, and network diagnosis.
PERFORMANCE CASE STUDY

Bufferbloat mitigation on VDSL2 with MikroTik
MSS clamping, CAKE queueing, traffic classification and DiffServ improved latency under load on a PPPoE connection.
F → A+bufferbloat grade
+600 ms → +2 msupload latency under load
Selective reachability diagnosis
Using traceroute and path analysis to identify where traffic was being filtered or dropped and guide escalation.
Read case study →External monitoring & SLA tracking
Independent uptime, latency and packet-loss monitoring to detect issues before users report them.
Read case study →Network security awareness
A practical look at why exposed topology and device information increases risk and how to reduce that exposure.
Read case study →PLATFORMS & TECHNOLOGIES
Vendor-aware, fundamentals-first.
I work across enterprise and SMB environments while keeping the focus on packet flow, protocol behavior, and operational clarity.

HOW I APPROACH A PROBLEM
Diagnose first. Change with evidence.
01
Map the path
Understand topology, addressing, VLANs, routing and dependencies before changing configuration.
02
Measure behavior
Use counters, routes, ARP/MAC tables, logs, packet paths and latency data to isolate the fault domain.
03
Implement safely
Apply the smallest useful change, validate the result, and preserve rollback options.
04
Document the result
Leave a clearer network: documented intent, repeatable steps, and better visibility for the next incident.

FAQ
A few common questions.
Do you work remotely?
Yes. I provide remote troubleshooting and network/system support, plus on-site services in Federal, Entre Ríos.
Can you troubleshoot mixed-vendor networks?
Yes. I work from protocol behavior and packet flow, then map that to the specific vendor syntax and platform.
Do you work with existing environments or only new deployments?
Both. Many engagements start with an existing network that needs diagnosis, cleanup, segmentation, documentation or performance improvements.
Can you help document the final configuration?
Yes. I can provide topology notes, configuration summaries, troubleshooting procedures and operational runbooks.
