Hello, I'm
Tyler Dunn
Full-Stack Software Engineer
4+ years shipping production software, from React and Next.js web applications to hardware-integrated instrumentation tools over gRPC and MQTT, across defense, test systems, and embedded environments.
Who I Am
I'm a software engineer based in Orlando, FL with 4+ years of experience shipping production software: React and Next.js web applications, Python-based instrumentation tools that interface with embedded firmware over gRPC and MQTT.
Most of my career has been in defense and test systems, where I've built real-time data visualization interfaces, high-throughput messaging layers, and cross-platform applications that engineers rely on daily. I care about writing software that's performant, accessible, and built to last.
Outside of work, I contribute to open-source projects like FLAC, qBittorrent, and Google's FlatBuffers, and build side projects that scratch my own itch. I'm currently looking for a senior engineering role where I can own systems end-to-end and have a meaningful impact on the product.
Experience
Production software across defense, test systems, and hardware-integrated environments.
- Drove the security analysis and designed a TLS-secured gRPC license authentication flow that replaced hardcoded SSH credentials, eliminating a credential-leakage vector from the TDR instrument software.
- Reworked the data pipeline in the TDR instrument application to raise sustained real-time streaming from 10 Hz to 15 Hz, giving engineering users a smoother, more responsive live view during measurements.
- Drove final-stage production hardening and UI polish for the Python-based TDR application, converting designer mockups into PyQt6 interfaces tuned for engineering instrumentation workflows.
- Led the Flutter front-end and MQTT data layer for a next-gen LMR test system, sustaining 30 Hz real-time updates and cutting UI frame drops by 50% under load.
- Established the CI/CD pipeline for the Flutter test-system project, automating builds and releases so the team could ship consistent, repeatable deployments without manual packaging.
- Migrated ~8,000 lines of a legacy VB6 application to VB.NET and extended a custom C# control application to cover previously unsupported relays in a switching-system automated tester.
- Engineered a high-volume real-time charting interface for hardware test systems, rendering nearly 400,000 temperature, voltage, and current telemetry points to support faster test monitoring and analysis.
- Built a custom WordPress plugin (jQuery/PHP) for dynamic player leaderboards and cut page load times by 33% through plugin refactoring and asset optimization.
Projects
Personal and professional projects I've built end to end.
MapleDoro
React + Next.js Web Application
- Built a Next.js + React toolkit for MapleStory end-game players (progression calculators, reset/event trackers, and symbol/HEXA/boss income utilities), backed by shared TypeScript utilities and timezone-aware client-side state for correct daily/weekly reset rollover.
- Built and deployed an ASP.NET (C#) API on a self-hosted Linux server, exposed securely through a Cloudflare Tunnel with managed traffic rules and rate limiting and no open inbound ports.
- Tuned the Next.js/Vercel production build to raise Google PageSpeed Insights Performance from 84 to 99, with perfect 100s in Best Practices and SEO.
Reptile Enclosure Automation
Full-Stack, Cross-Platform Application
- Designed and built the React Native frontend targeting web, iOS, and Android from a single codebase, with flows to provision and monitor any number of enclosures with per-enclosure sensor thresholds.
- Architected the Firebase + Express/Node backend with a multi-tenant data model, real-time temperature/humidity ingestion, and threshold-driven alerting that scales per account.
