Curious by nature. Builder by instinct.

I like understanding how things work — then making them work better.

LeaseLoop

One workspace for everyone around a rental property, from owners and managers to renters and the people who fix things.

Problem
Renting out a property runs on scattered texts, spreadsheets and email threads. Owners can't see what's happening, renters can't tell whether a repair is moving, and nobody has a reliable record of who agreed to what.
Approach
Put properties, leases, rent records, maintenance, documents and messages in one place, and let each person see only what their relationship to the property allows. Pair it with an operations agent that handles the follow-up work but leaves every decision to a person.
Implementation
Node.js and Express 5 on PostgreSQL, with Better Auth sessions and strict zod validation on every input. Authorization is relationship-based and enforced on the server for every request: managers are assigned per property, renters reach only their active lease, and providers reach only the work assigned to them. Every change is written to an append-only audit log in the same transaction. The agent runs on deterministic rules, with a language model optional. Integration tests run against an embedded Postgres, with Playwright for the browser.
Outcome
The public site is live at leaseloop.ca, and the product is being hardened for a wider beta.

The cello

What shapes me

The cello is the slowest teacher I have. A passage doesn't get better because I want it to; it gets better when I slow it down, listen to what's actually happening, fix one thing, and play it again.

That loop of deliberate practice, honest feedback and patience is the same one I use to build software. Ship a small version, watch how it behaves, correct it, repeat.

I've taught cello since 2019, which taught me something else: explaining a thing clearly is the fastest way to find out whether you understand it. Music is also where I get to make something that isn't meant to be useful. I think that matters for the useful things too.

More about me

The window

How I see things

From up here Calgary looks like what it is: a system. Streets, transit, power, weather and a million small decisions, all affecting each other.

I'm drawn to problems like that. Before I build anything I try to see the whole loop: who's involved, what information moves between them, and where it gets stuck. Most frustration lives at those hand-offs.

Good automation doesn't replace the people in the loop. It takes the repetitive part off their plate, keeps an honest record of what happened, and leaves the decisions that matter with them.

What I'm exploring now

Selected work

Three things I've built, and why they're built that way.

  1. StartupLive

    LeaseLoop

    One workspace for everyone around a rental property, from owners and managers to renters and the people who fix things.

    The problem Renting out a property runs on scattered texts, spreadsheets and email threads. Owners can't see what's happening, renters can't tell whether a repair is moving, and nobody has a reliable record of who agreed to what.

  2. Research systemPrivate

    Valuation App

    A weekly research run that values groups of public companies six ways and keeps every result as history.

    The problem Valuing a company properly means pulling filings, normalising the numbers and running several models. Doing that across a whole sector every week by hand isn't realistic, and a spreadsheet quietly overwrites last week's thinking with this week's.

  3. Desktop appv0.3

    Life OS

    A desktop app that keeps a school year and a personal to-do list in one calm place.

    The problem Classes, assignments, grades, calendars and personal tasks usually live in five different apps. Keeping them in sync is its own chore, and none of them answers the simple question of what actually needs doing today.

About me

The person behind the room.

I'm Nathan, a finance student in Calgary studying Financial Technology & Innovation at SAIT, after starting out in software engineering at the University of Calgary. I build software for problems I run into myself: rentals where nobody has the full picture, company research that takes too long by hand, a school year spread across too many apps.

Most of my jobs have come down to keeping information accurate and moving: baseline data for a youth concussion study, data evaluation for TELUS International, coordinating engineers and subcontractors on the 11‑29 runway project at YYC, and running guest experience at a luxury lodge. Finance taught me to want the numbers behind a claim; software lets me make those numbers easy to trust. I co-founded LeaseLoop with Noah.

Away from the desk there's the cello. I trained through the Royal Conservatory and Mount Royal's Academy for Young Artists, played with the Calgary Youth Orchestra, and have taught students since 2019. Practice is where I learned that most progress is small, honest corrections repeated until they stick.

On the bench right now.

  • A background operations agent for LeaseLoop

    Lyra handles the follow-up work around a rental: chasing missing details, checking provider credentials, collecting completion evidence. Every action is logged and can be paused or undone.

  • Data quality in the Valuation App

    Auditing past research runs for stale prices and impossible estimates, fixing the causes, and flagging affected history instead of rewriting it.

  • Life OS v0.3

    A slimmer redesign focused on just School and Personal, with an editable grading scale and GPA calculation.

  • Junior VP of Innovation, SAIT Finance Society

    Improving the society's website, including a parser that keeps the job board current from LinkedIn postings, and helping run a paper trading competition and industry speaker events.
