Projects

Most of my professional work is proprietary, so I describe the types of systems I build without sharing internal content. For hands-on examples, I include personal projects that show how I think and build.

Professional work (described)

Forecasting framework & scenario model

Market analytics system (non-public)

A structured approach to turning market signals into consistent directional views and scenarios. Designed to make assumptions explicit, track what changes them, and communicate outcomes clearly.

ForecastingScenario AnalysisData Modeling

Supply–demand balances + trade flow structure

World analysis (non-public)

Integrated balance structure that connects production, operating rates, trade flows, and schedules into a coherent view of market tightness and risk.

BalancesTrade FlowsOperating Rates

Indicator monitoring + dashboard workflow

Internal analytics (non-public)

Repeatable monitoring workflow that reduces manual reporting and helps focus attention on the few indicators that actually move the story.

DashboardsAutomationDecision Support

Standardized reporting templates

Consistency + speed

Structured templates that keep outputs consistent across cycles and reduce friction when markets change quickly.

Personal projects (hands-on)

HVAC Optimization & Smart Home Automation

Weighted comfort logic + reliable execution

Built a multi-room HVAC control approach using weighted temperature averaging, priority overrides (e.g., nursery comfort), and sensor aggregation to balance comfort and energy efficiency. Implemented with a mix of YAML automations and Node-RED flows to keep the logic explicit, testable, and repeatable.

Home energy monitoring + gas usage dashboard

From raw meter signal to usable insights

Integrated a gas meter signal into Home Assistant and built a dashboard to track consumption and make billing/usage trends easy to understand. Focused on reliability (signal capture), clean entities, and meaningful presentation.

Proxmox homelab for services + experimentation

Infrastructure learning lab

A small homelab environment used to run services and experiment safely: virtual machines, resource planning, segmentation, and maintenance workflows.

ProxmoxLinuxNetworkingVMs

Local LLM on a mini PC (self-hosted AI)

Private inference + practical integrations

Set up a local language model service on a mini PC and integrated it into personal tooling for experimentation. Focus areas include privacy, latency, reliability, and making AI useful in real workflows (not just demos).

Discord bot (automation + community utilities)

A practical coding project

Built a Discord bot to automate community workflows and add quality of life features. This project is a good example of iterative development: add features, observe behavior, refine.

PythonDiscord APIAutomation

DIY & electronics experiments

Hands-on systems thinking

A collection of small electronics and automation builds: sensors, control logic, and practical household upgrades. I enjoy the mix of constraints — power, reliability, and clean wiring — and making it all work end-to-end.
