Why

Small businesses needed one place for billing that could grow into full operations — inventory, CRM, people, reporting, and marketplace work — without bolting on disconnected tools.

Business-management SaaS that evolved from invoicing into a broader operating system for multi-business teams.

II — where

experience

From fintech approvals to operations platforms, these are the systems I helped shape for reliability, clarity, and measurable impact.

A → B, the Maps way

Bidirectional Dijkstra on real streets — two search fronts flood the road network from both pins until they meet, then only the shortest link stays.

Loading streets…

Loading OpenStreetMap streets…

Tendrils are drawn only on OSM road geometry — they follow the same streets you see on the basemap, not a fake grid.

NetScope — local-first Wi-Fi visibility

NetScope

In progressJava · open source · since 2026

Deepening Java and Spring-ecosystem skills by shipping a real product — not a tutorial checklist.

NetScope is a local-first Wi-Fi monitoring and network-visibility tool. Install it, run it on a machine connected to the network, and inspect what the environment shows — without a hosted account, website registration, or cloud dashboard. The goal is simple security awareness for non-tech users: when something feels off, the phone is not always the only culprit; the Wi-Fi itself can be the weak link. Visibility helps people notice risk and harden the network before devices get exposed.

  • Local install and local execution
  • Wi-Fi / network visibility for everyday users
  • No cloud account required for the core use case
  • Open-source Java

Fit

I take complex products from zero to production—shaping the architecture, leading delivery, solving critical engineering challenges, and owning reliability at scale across fintech, CPaaS, healthcare, facilities operations, and products I’ve built myself.
