About Me

Technically, I specialize in Rails + Postgres backends with React frontends. Practically, I specialize in making the hard change easy, whether that’s an optimization in ActiveRecord, a query refactor, or guiding a team through shifting priorities.

Above-the-line (ATL) Markups — Ediphi

Customers often need to include costs tied to subsets of line items — like insurance, compliance fees, or jobsite utilities — not just the overall project total. Ediphi’s original markup feature worked only “below the line,” applying formulas at the aggregate level. To meet customer demand, we introduced Above-the-line Markups, which allowed markups at the line-item level, applied before below-the-line calculations. This gave estimators finer control and more realistic forecasts in the preconstruction phase.

AG Grid Upgrade — Ediphi

Estimating in construction relies on spreadsheet-like tools. Traditionally, Ediphi’s estimating platform used multiple grid libraries across different features — Estimates, Rooms, Area Sheets, Quantity Take-offs — which created a disjointed experience for customers. To unify this, we led an initiative to standardize all grid experiences under a single framework: AG Grid, wrapped in a reusable internal component called EdiphiGrid.

Budget Changes - Procore

The legacy Budget tool allowed customers to shift money between codes, but lacked flexibility: changes couldn’t connect to other Procore tools, workflows, or accounting integrations. Customers also couldn’t move money in more complex ways (many-to-one, one-to-many). To solve this, we built a new object within the Budget tool called Budget Changes, a modern framework for tracking and managing financial modifications.
