Financial Forecaster

finmod.jonssonassociates.com

Phase 1 MVP · Live

A lightweight three-statement forecasting tool aimed at founders and operators who want runway visibility without standing up a full FP&A stack. Currently labelled Phase 1 MVP.

Builds an income statement, balance sheet, and cash flow over a 12 to 36 month horizon from a single set of line items, drivers, and scenario overrides. Models recurring (seven frequencies) and one-time costs, supports driver-multiplied and percent-of-line amount types, applies federal C-corp plus per-state taxes with minimum franchise floors, and reports cash, average burn, runway, and twelve-month net income on the dashboard. Aggregates roll up cleanly across weekly, monthly, quarterly, and yearly views.

Project Management · Scheduling

PERT

pert.jonssonassociates.com

Built · Live

A modern, multi-user implementation of the PERT (Program Evaluation and Review Technique) scheduling method, built for teams that want optimistic, realistic, and pessimistic estimates with an automatic critical path rather than a static Gantt chart.

Captures activities with O / R / P estimates, computes TE = (O + 4R + P) / 6, runs a forward and backward pass on the dependency network, and surfaces the critical path. Validates the network for cycles, orphans, and missing dependencies; warns before any edit that would change the critical path. Supports milestones with anchored calendar dates and projects configured in hours, days, or weeks against a custom work calendar.

Genealogy · Visualization

FamViz

famviz.jonssonassociates.com

v1 · Live

A GEDCOM-based family-tree merge and visualisation tool. Parsing, merging, and persistence all happen in the browser; localStorage holds the active tree.

Imports GEDCOM files, reconciles people across sources, and renders a high-density tree view. Built on TanStack Start, React 19, and Vite 7, with Zustand stores for the active tree and an independent merge workspace.
