Brandon Luz-Sansone

Core engineer on FortiMonitor, Fortinet's network-monitoring and observability platform. Progression: Software Engineer at Panopta (acquired by Fortinet, Dec 2020) → Senior Software Engineer → Staff Software Engineer (2023).

• Took over an in-progress Vue 1 → Vue 2 migration at roughly the halfway point — with the application running two codebases in parallel — and drove it through to a single, fully migrated Vue 2 codebase.
• Spearheaded the conversion from a server-rendered, multi-page (Jinja) app to a client-side single-page application — planning and architecting the effort and serving as the team's go-to lead for routing, state management, and data loading.
• Architected a SharedWorker-based WebSocket event-routing layer with namespace subscription matching and global / page / component scopes, powering real-time monitoring updates and a badge and alert notification system across the dashboard.
• Diagnosed and fixed memory leaks in the Vue 2.7 SPA using Chrome V8 heap-snapshot analysis — clearing ~39K accumulating detached DOM nodes from a third-party tree/modal component plus leaks in event-listener cleanup, chart re-rendering, and table reinitialization — to reduce memory growth in long-running sessions.
• Drove the migration of the FortiMonitor build system from Webpack 4 to Rspack 2, resolving dependency and hot-reload issues and shipping a custom Express + Rspack dev-middleware setup that cut full build times from roughly 9 minutes to about 20 seconds.
• Built the front end of FortiMonitor's network-topology views — an interactive KeyLines graph of live device-and-link maps and a Leaflet-based geographical view of customers' networks — letting users pan, zoom, and explore large infrastructures; a teammate handled the backend.
• Contributed ongoing enhancements and bug fixes across the team's customizable widget dashboard — multiple real-time widget types (line and bar graphs, counters, tables, gauges, heatmaps, geomaps, and more) that each updated live from WebSocket messages, graphing time-series data for real-time views of infrastructure.
• Contributed to the team's shared Python TurboGears backend across API feature work and reliability improvements.
• Sole developer of FortiMonitor's cross-platform mobile app, building it from the ground up with NativeScript-Vue for iOS and Android — letting users view and triage active incidents, backed by a Python REST API with Firebase push notifications for real-time alerts.

Progression: Front-End Intern → Junior Front-End Developer → Software Developer.

• As part of the team, rebuilt the company's e-commerce platform from Shopify into a custom React / Redux app on a Node / Restify backend with AWS (DynamoDB, Elasticsearch, Cognito), Stripe payments, and a Contentful-managed homepage; also worked on an early React Native port that shared Redux logic across web and mobile.
• Independently migrated a Salesforce customer portal into a standalone React / Redux application, building the backing REST API that wrapped the Salesforce data store so users could manage account details and inventory directly.
