DEVELOPMENT/v3.0.1

Industrial Protocol Analysis

Zeek plugin development for Siemens SINEC Security Monitor, an OT security monitoring platform for passive, continuous visibility into industrial assets, threats, and network intrusions during production.

>>

deploy industrial_protocol_analysis --inspect

Project Details

+Researched OPC UA protocol behavior within an R&D lab environment using PLCs, generated OPC UA traffic, Wireshark, and UAExpert to simulate and understand normal and abnormal industrial communication scenarios.

+Developed a Zeek-based plugin for Siemens SINEC Security Monitor to inspect and parse OPC UA traffic and generate event-specific logs for selected OT cybersecurity monitoring use cases.

+Implemented custom behavior checks and detection logic around protocol events, communication behavior, certificate handling, access-level validation, and write-response conditions.

+Defined attack procedures and generated test-data scenarios to validate how the plugin detected and logged targeted OPC UA activity in support of monitoring and detection engineering.

MAIN/v2.1.4-LTS

Expenses Recorder

Where budgets meet common sense - simple, predictable, and actually nice to use.

>>

deploy expenses_recorder --inspect

Project Details

+Tracks budgets and sub-budgets that roll over month to month.

+Auto-populates new month budgets with your last setup - no manual rebuilds.

+Flask serving clean JSON straight to the Next.js dashboard.

+UI focuses on clarity: every cent, every category, zero clutter.

RND/v1.0.0-RESEARCH

AI4Security Research

Internal Siemens research into whether AI could analyze industrial PCAP data using both open-source cybersecurity-tuned models and Azure fine-tuning to help distinguish benign versus potentially malicious network behavior.

>>

deploy ai4security-research --inspect

Project Details

+Analyzed industrial packet captures with a co-op student to see whether AI could reduce manual PCAP review effort in OT environments.

+Evaluated open-source models that had already been fine-tuned for cybersecurity tasks, alongside Azure-hosted models trained on structured JSON examples derived from packet analysis.

+Compared fine-tuning against one-shot, multi-shot, and chain-of-thought prompting, finding that prompt-based methods handled variation better but still lacked detection-grade accuracy.

+Shifted toward NetFlow-style context and an agentic validation loop where one model generated expected traffic structure and another checked it before accepting the analysis.

Branch: PLANNINGv1.0.0-PROPOSAL

PLANNING/v1.0.0-PROPOSAL

Resource Allocation Tool

A proposal to turn an Excel-based employee time-allocation tracker into a web application so managers could see team capacity more clearly and judge whether additional projects could be taken on. The effort ended after phase one when a management change removed the need for continued development.

>>

deploy resource-allocation-tool --inspect

Project Details

+Defined a phased roadmap for replacing a spreadsheet-based employee time-allocation process with a dedicated internal web application.

+Proposed a stack built on Next.js, Flask, PostgreSQL, and Docker to support dashboards, uploads, and maintainable service boundaries.

+Included authentication, dashboard, and upload workflow planning to clarify how users, system logic, and the database would interact.

+Centered the value proposition on transparency, collaboration, access control, integration potential, and better version governance than Excel.

+The project was cancelled after phase one delivery because a change in management meant the organization no longer needed to continue the tool.

RND/v1.3.0-POC

Northbound API

A proof-of-concept Northbound API interface for Siemens SINEC Security Monitor so processed security data and asset information could be extracted, displayed in an external dashboard, or forwarded into other downstream workflows.

>>

deploy northbound-api --inspect

Project Details

+Defined and developed API interfaces inside SINEC Security Monitor to expose processed data for external consumption.

+Built a stakeholder-facing proof of concept showing how extracted information could be surfaced outside the core product.

+Developed a companion dashboard using Next.js and Flask to demonstrate data retrieval, visualization, and workflow integration.

+Used the interfaces to retrieve processed data and interact with the SSM database for asset information, security events, and alerts.

LEGACY/v1.8.2-STABLE

Automated Musicians

Where music meets algorithms - a creative blend of theory, pattern recognition, and composition automation.

>>

deploy automated_musicians --inspect

Project Details

+Analyzes sheet music patterns and converts them into structured ABC notation.

+Implements algorithmic composition - generating new melodies based on learned musical structures.

+Built modularly: data extraction, pattern recognition, and generation pipelines are all isolated for testing.

+Presented at UNB as a capstone project, later featured on CBC Radio for its innovation in AI-driven music.

+Team project built with collaboration across data analysis, algorithm design, and full-stack development.
