RETCON Software Solutions is an independent studio. We design and ship everything API-first and MCP-first, run local AI wherever it fits, and harden it with a cyber-aware foundation. When you need velocity, we deploy forward and work as an extension of your team. No throwaway demos. Just systems that scale and survive.

  • Forward-Deployed Engineering

    We embed with your team, in your stack, on your hardest problems, and ship alongside you until it works in production. An extension of your team, not a hand-off.

  • Product Engineering

    End-to-end web products on Next.js and FastAPI: auth, billing, metering, all of it. From idea to a deployed, paying SaaS.

  • AI & MCP Integration

    Agents, RAG and GraphRAG, and Model Context Protocol servers that give AI first-class, governed access to your data and tools.

  • Desktop & Cross-Platform

    Native-feeling desktop apps with Tauri: small, fast, secure, and shipped to every platform from one codebase.

  • Embedded & Systems

    Firmware and real-time systems in C, C++, and Rust. Defensive code at the hardware edge that still hits its timing.

  • Cloud & DevOps

    Vercel, Docker, CI/CD, and self-hosted infrastructure that deploys itself and stays up. Pragmatic, observable, reproducible.

  • Security-First

    A cyber-aware foundation means threat modeling and hardening are built in from the start, not bolted on at the end.

.

A live product-intelligence SaaS that scores e-commerce products by market saturation, velocity, and trend phase. It ships as a key-authenticated REST API, an MCP server for AI agents, and a Next.js and Supabase web app with usage metering and Stripe billing, all running on Vercel.

    GNSS-Denied Autonomous Navigation

    A real-time embedded nav system from a Sandia National Laboratories-sponsored senior capstone. Converted a MATLAB/Simulink prototype to C++ and ROS 2 on a Raspberry Pi 4 inside a 15 W power budget, with an Extended Kalman Filter fusing GNSS/INS, LIDAR, and wheel-encoder data to hold sub-15 cm accuracy with no satellite signal. Led a 6-person team to 100% requirement-to-test coverage.

    RIFFSTICK Controller

    A 3D-printed, small-form-factor take on the Rock Band and Guitar Hero controllers for Clone Hero. Contributed a custom PCB with an integrated Raspberry Pi Pico, built from easy-to-source parts.

Andrew Gallagher, Founder · Full-Stack & Forward-Deployed Engineer
// Andrew Gallagher

I build AI-driven web and desktop products end to end, with security treated as a habit rather than an afterthought. Before going independent I wrote embedded firmware for tactical communication radios at Canyon AeroConnect in ANSI C, Python, and Assembly, and ran enterprise IT and security there. That range, from low-level firmware to full-stack platforms, is what I lean on when a project needs both.
