GIS Professional

I’m a GIS professional with roots in HR analytics and project management — and a deliberate move into geospatial work.
I use ArcGIS Pro, QGIS, and ArcGIS Online to turn spatial data into maps, dashboards, and insights that support decisions. My background spans large-dataset analysis, Agile delivery, and communicating findings to non-technical audiences.
This site is where I document what I build and learn.
Based in Toronto.

What I bring

GIS & Spatial Analysis

ArcGIS Pro, QGIS, ArcGIS Online. Geocoding, watershed modeling, raster classification, field data collection with Survey123 and Field Maps.

Data at Scale

Built compensation models and dashboards on datasets of 300K+ records. Comfortable with messy data, validation, and turning numbers into decisions.

Project Delivery

PMP-certified. Led annual budgeting cycles, Agile ceremonies, and cross-functional dashboard builds from requirements to rollout.

Stakeholder Communication

Years of presenting analysis to senior leaders. I design maps and reports for the person reading them, not just the person making them.

Problem-Solving & Curiosity

I ask why before I build. Most of my best work started with noticing a gap in the data or a question no one had bothered to answer yet.

Adaptability

Three countries, four industries, two career pivots. I learn new tools and contexts quickly because I've had to.

Collaboration Across Languages & Cultures

Worked in English, Ukrainian, and Russian across distributed teams. Comfortable bridging technical and non-technical audiences — and cultures.

Ownership

I finish what I start. The portfolio on this site exists because I set a transition goal and worked it while holding a full-time job.

Featured Projects

Toronto Residential Break-and-Enter Analysis

This project normalizes 2015–2025 residential B&E data by dwelling count, then builds a space-time cube and runs EHSA to track how clusters shift over time. HSA and Cluster and Outlier Analysis are compared to tell real clusters from noise. Sporadic hot spots dominate north-central Toronto, Etobicoke oscillates, Scarborough and East York stay cold. Per dwelling, houses face about 2× the break-in risk of apartments city-wide, widening to 3–5× in the highest-rate neighbourhoods.

Newmarket Heritage Properties

Newmarket's Municipal Heritage Register lists 318 properties — but no map, no photos, no context. This project fills that gap: geocoding the register, georeferencing a historical town map, conducting field data collection via Survey123 and Field Maps, and publishing results through an ArcGIS Dashboard and Instant App. Field visits revealed 28 properties with outdated plaque status and 24 plaques not in the register at all.

Where the Water Flows

Watershed analysis of four rivers — Humber, Credit, Holland, and Nottawasaga — showing how a subtle elevation divide shapes contrasting flow directions across the land between Georgian Bay and Lake Ontario. Built using DEM data, ArcGIS hydrology tools (Fill, Flow Direction, Flow Accumulation, Raster to Polyline, Contour), and published as a StoryMap.
