Brokerage, asset management and property management, with the tools to run them better.

Six years across Denver and St. Louis: closing deals at Marcus & Millichap, turning around a 252-unit portfolio, and managing 480 units for 26 owners. Along the way, I built tools that save hours of busywork and catch the costly mistakes people miss.

Built at Hello Management

Tools I built to better run an 1,800-unit portfolio.

Each one started as a recurring problem I hit as an account manager. They're described here by what they do and what they changed, not how they're built.

Budget builder

Takes a property's rent roll and trailing twelve and produces a first-draft annual operating budget, mapped to the chart of accounts and checked for red flags before an owner ever sees it.

Saved upper management hours of budgeting time by consolidating financial statements and mapping GL codes into one standard budget.

Rent tool

Tracks and archives every “for lease” listing across public sites, building a rent history that outlasts the listings themselves.

Tracks competitor rates, minimizes loss-to-lease and flags submarkets headed for strong rent growth.

Delinquency automation

Flags residents likely to fall behind before they do, and keeps follow-up on schedule so nothing slips between rent day and a notice. When a file does go legal, it generates the notices and filing paperwork automatically.

Earlier intervention and reduced delinquency across my book. Several hours of paperwork saved each month, with fewer errors, fewer attorney kickbacks and a faster path to eviction.

Lease-to-ledger audit

Compares what each lease says against what's actually being charged: missed escalations, fees never set up, concessions that never ended.

If it's on the lease, it's on the ledger. The first run, on a property we'd just taken over from its previous manager, checked 89 leases against 78 tenants and flagged 36 tenants with no lease on file, 10 deposit mismatches, 3 leases with no expiration date, and one template error that left a required monthly fee off 36 leases.

Phone system rebuild

Analyzed months of company calls and rebuilt the main line around them, eliminating the workaround tenants had learned of going through the leasing line, which buried the leasing team in calls meant for resident managers. The new system recognizes 2,281 resident numbers and routes each caller to their own manager across 164 properties.

Found 38.6% of call traffic bypassing the phone tree, 450 calls a month abandoned inside the old menu and a 600-call-a-month dispatch line listed in no directory. Along the way, flagged 452 units with no assigned manager.

Tech stack audit

Reviewed every subscription, service and transaction fee the company paid. Replaced AppFolio's AI maintenance and resident add-ons with an in-house knowledge base built on company protocol and custom directives, cut the outside call center and showing service, and moved owner and vendor payments off per-check fees.

Discovered about $7,500 a month in cumulative savings, including $2,300 from the AI add-ons, $850 in payment fees, $800 from the showing service and $800 from the call center. Separately, built a backend integration that cut screening and application costs from $55 to $18 per applicant, 67% less, across roughly 250 applicants a month, widening the applicant pool.

Also: custom workflow automations in RealmX and agentic tools for day-to-day operations. Happy to walk through any of these in an interview.

About

A manager's view, with a broker's eye for value.

I started in commercial brokerage at Marcus & Millichap, advising multifamily owners on what their buildings were worth and how to position them. I then moved inside the asset: turning around a 252-unit portfolio in St. Louis, and later managing a 480-unit book for a Denver management company.

Running properties showed me where time and money leak out of the business, so I started building tools to stop it. That work grew into a technology role. I bring both to every building: knowing what drives value, and knowing how to make the day-to-day run cleaner.
