Curated implementation work divided into Primary Engineering Projects (infrastructure, monitoring, and security), Secondary Applications, and Anonymized Case Templates showing operational problem-solving patterns.

CODE & IMPLEMENTATION

SELECTED ENGINEERING PROJECTS

> Curated engineering projects demonstrating real-world technical depth across AIOps, Linux server hardening, monitoring, and infrastructure automation.

MonitoringCompleted

Zabbix Network Monitoring Tool

The Engineering Challenge:

IT administrators and network engineers lack a centralized, automated monitoring setup to track server health, endpoint availability, and network devices.

What I Built:

Configured a complete Zabbix network monitoring environment for servers, switches, and endpoints. Implemented proactive alert thresholds, custom metrics gathering, and automated availability dashboards.

Tech Stack:
ZabbixLinuxSNMPShell ScriptingNetwork Monitoring
AIOpsCompleted

Centralized Syslog & Elastic Stack (ELK) Telemetry

The Engineering Challenge:

Dispersed infrastructure logs across firewalls, Linux servers, and Active Directory make incident triage and security auditing slow and manual.

What I Built:

Engineered a centralized Syslog ingestion server on Ubuntu integrated with Elasticsearch, Logstash, Beats, and Kibana. Enabled structured parsing, index lifecycle management, and real-time visualization for multi-device log streams.

Linux HardeningCompleted

Stateful Linux Packet-Filtering Firewall

The Engineering Challenge:

Unprotected Linux server endpoints are vulnerable to unauthorized access and port exploitation without custom packet filtering and logging.

What I Built:

Implemented a stateful packet-filtering firewall using Linux iptables on Ubuntu Server with a default-deny policy. Configured granular rule sets allowing SSH, HTTP, and HTTPS while strictly dropping unwanted traffic and logging dropped packet telemetry.

CyberScan — Async Network Reconnaissance & SSL Auditor

The Engineering Challenge:

Expired SSL certificates and unexpected exposed open ports often go unnoticed until external systems fail or security audits flag them.

What I Built:

Developed a high-performance, multi-threaded asynchronous port scanner and SSL monitoring dashboard. Built socket-based network discovery, real-time service detection, and SSL certificate expiration alerting.

Infrastructure AutomationCompleted

System Management & Automation Suite

The Engineering Challenge:

Repetitive system administration tasks—process monitoring, directory health checks, and log rotations—consume excessive administrative time when handled manually.

What I Built:

Built a modular automation toolset using Python and Bash for headless Linux server management. Automated critical process health surveillance, disk utilization threshold checks, and automated system remediation routines.

PDF2Excel AI — Industrial OCR Extraction Pipeline

The Engineering Challenge:

Operations and finance teams spend hours manually re-typing unstructured data from complex multi-page industrial PDFs, OBL sheets, and warrants into spreadsheets.

What I Built:

Engineered a full-stack OCR and table extraction pipeline using React and Express. Integrated high-precision tabular parsing to process complex industrial documents into clean, multi-sheet formatted Excel workbooks.

Private AIOps Alert Triage & Root Cause Analysis Platform

The Engineering Challenge:

Complex infrastructure monitoring environments flood engineering teams with cascading alerts, obscuring root cause dependencies during major incidents.

What I Built:

Built as part of professional infrastructure engineering work. Connects monitoring signals with workflow automation and incident correlation routines to accelerate root-cause identification and operational response.

ILLUSTRATIVE SCENARIOS — NOT CLIENT STORIES

ANONYMIZED PROBLEM TEMPLATES

> How we systematically analyze and remediate common infrastructure failure modes.

Case Template (Anonymized Pattern)

Exposed SSH + shared admin passwords on a Linux server

Problem: A typical small-team Linux box allows password login over SSH, root login is enabled, and the same admin password is shared across two founders and a contractor.

Approach: Hardening checklist applied: key-only SSH, root login disabled, per-user accounts with sudo audit, shared password retired, UFW reduced to required ports only, fail2ban rate limiting configured.

Illustrative scenario describing the type of problem fixed — not a client story. No client has engaged yet.

Case Template (Anonymized Pattern)

Nobody notices expiring certificates or forgotten open ports

Problem: A production site's TLS certificate expires on a Sunday, and an old staging service has been internet-facing for months with default credentials nobody remembers.

Approach: External port scan and certificate inventory run; findings listed with severity; expiry monitoring and a patch/close plan handed over; risky staging service locked down.

Illustrative scenario describing the type of problem fixed — not a client story. No client has engaged yet.

Case Template (Anonymized Pattern)

Customer PII in shared drives with no consent record

Problem: A 20-person business keeps customer spreadsheets in a shared drive: sales, support and an intern all have edit access, and nobody can say where personal data lives or what consent was captured.

Approach: Personal-data map built (what is stored, where, why), least-privilege access applied, retention/deletion steps written down, and an incident-reporting checklist handed over.

Illustrative scenario describing the type of problem fixed — not a client story. No client has engaged yet.
