I am passionate about network engineering and love exploring how technology connects the world. I enjoy travelling and learning from different perspectives. Currently building my skills in AI Networking, combining deep protocol knowledge with Python automation and modern AI tooling to make network operations smarter and faster. My hands-on experience spans routers, switches, BGP, OSPF, EVPN/VXLAN, ECMP, MPLS, and SDN across enterprise and hyperscale environments.

Two tools. Zero friction.

Paste your data, click once, get results. Built for the middle of an incident, not ideal conditions.

Simple enough to use mid-incident

No logins, no configuration, no learning curve.

01

Paste your log

Copy raw output directly from your router, firewall, or monitoring system and paste it in. Any format works.

02

Set context

Choose environment, network type, and focus area. The AI adjusts its analysis to your situation.

03

Get results instantly

Receive severity-coded findings with specific, actionable recommendations ready to act on or share with your team.

Log Redactor Anomaly Detector

How I built this

This site started as a personal project to solve a real problem I faced regularly in network operations. Here is the full honest story of how it came together, the tools I used, and what I learned along the way.

01
Domain

IONOS for the domain name

I registered networkforai.com through IONOS. The setup was straightforward and they included a free business email address for the first month. After the trial, the email plan is around $5 per month. The domain registration itself is reasonably priced and the IONOS dashboard is clean and easy to manage DNS records from.

02
Hosting

Netlify for web hosting and free SSL

IONOS does not include a free SSL certificate, which means the site would show "Not Secure" in the browser. I moved the hosting to Netlify, which solved this completely. Netlify provisions a free Let's Encrypt SSL certificate automatically, handles global CDN distribution, supports instant deploys by drag and drop, and has a generous free tier with 100GB bandwidth per month. It was the right call.

03
Log Redactor

Python regex for log redaction

The log redactor is built with Python regex patterns running entirely in the browser via JavaScript. I mapped out every sensitive data type that appears in network logs including IPv4 and IPv6 addresses, MAC addresses, BGP community strings, hostnames, and credentials, then wrote regex rules to detect and replace each one. Tokenization ensures the same IP always maps to the same token so the log stays readable while all sensitive data is masked.

04
Anomaly Detector

LLM for intelligent log analysis

The anomaly detector sends your log to Google Gemini, a large language model, which reads and understands the log the same way an experienced engineer would. It identifies patterns, correlates events, assigns severity levels, and generates actionable recommendations. This kind of reasoning is not possible with regex alone and is where AI genuinely adds value on top of traditional rule-based approaches.

How a company can use these tools

These tools were built for individual engineers but the same problems exist at scale inside organizations. Here is how teams and companies can put them to work immediately.

NOC and operations teams

Engineers can redact logs before escalating to vendors or TAC in seconds instead of spending 10 to 15 minutes manually scrubbing each file. The anomaly detector gives a first-pass triage during incidents when speed matters most.

Security and compliance

Consistent automated redaction removes the human error risk from log sharing. Every sensitive field is masked before data leaves the organization, supporting data handling policies and vendor security requirements without slowing down the team.

Training and onboarding

Junior engineers can paste real logs into the anomaly detector and immediately see a structured explanation of what each issue means and what to do about it. This accelerates skill development without requiring a senior engineer to explain every incident from scratch.

If your organization wants a customized version of these tools, with your own branding, internal hosting, a backend API proxy so engineers do not need personal API keys, or integration with your existing ticketing and monitoring systems, I am open to conversations. Reach out at [email protected]

Tools coming in the next few months

I am actively planning the next set of tools based on real problems I have seen in network operations. Here is what is on the roadmap.

Coming soon

BGP Config Validator

Paste a BGP configuration and get an AI review of potential misconfigurations, missing route policies, and security risks before pushing to production.

Coming soon

Network Change Summarizer

Paste a change request or diff and get a plain-English summary of what is changing, what the risk is, and what rollback steps should look like.

Planned

OSPF and BGP Troubleshooter

An interactive tool that walks through a structured troubleshooting flow for OSPF adjacency failures and BGP session issues, guiding engineers step by step.

Planned

Runbook Generator

Describe an incident type and the tool generates a draft runbook with escalation steps, verification commands, and rollback procedures tailored to your environment.
