01

RETCON is an independent studio. Everything ships API-first and MCP-first, runs local AI wherever it fits, and sits on a cyber-aware foundation. When you need velocity, we deploy forward and work as an extension of your team.

  • 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.

    • Your stack
    • TypeScript
    • Python
    • Rust

  • 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.

    • Next.js
    • FastAPI
    • Supabase
    • PostgreSQL
    • Stripe

  • AI & MCP Integration

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

    • MCP
    • GraphRAG
    • Neo4j
    • Local LLMs
    • Whisper

  • Desktop & Cross-Platform

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

    • Tauri
    • Rust
    • React
    • TypeScript

  • Embedded & Systems

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

    • Embedded C
    • C++
    • ROS 2
    • Raspberry Pi
    • KiCAD

  • Cloud & DevOps

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

    • Docker
    • GitHub Actions
    • Vercel
    • Nginx
    • PostHog

Every engagement

Security is the foundation, not a line item.

Threat modeling and hardening are built in from the first commit, not bolted on at the end.

  • Threat modeling
  • CodeQL
  • SIEM (Wazuh)
  • Reverse-proxy hardening
  • Defensive C

02

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.

03

A cross-section of what we've shipped beyond Dropr, from private AI tooling to satellite-denied robotics. Every one built end to end.

  • AI · Tooling

    Vokalizr

    A private note-taking tool. Whisper handles meeting transcription and locally-run LLMs do the summarization, so it all stays on your own hardware. A self-hosted answer to Notion AI and Fireflies.

    • Python
    • Whisper
    • Local LLMs
  • Knowledge Graphs · Self-hosted

    Synapse

    An explorer and visualizer for Neo4j knowledge graphs. Browse nodes and relationships, run live Cypher, and watch the whole graph render and update in the browser. Fully Dockerized and self-hostable.

    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.

Short loops, working software early, and no surprises. You see progress in your own environment from the first week.

  1. Discover

    We pin down the real problem, the success metric, and the threat model before writing a line of code.

  2. Prototype

    A thin, working vertical slice in your stack, fast, so decisions get made against real software instead of slides.

  3. Ship

    Production deploy with CI/CD, observability, and hardening in place. Built to be run, not just demoed.

  4. Hand off or stay

    Clean docs and a real handover to your team, or we stay on to keep improving it. Your call.

Ways to engage

  • Forward-deployed

    We join your team and work inside your codebase, rituals, and tools on a weekly cadence.

    Best for

    Teams that need senior velocity now

  • Fixed-scope build

    A defined deliverable with a clear scope, timeline, and acceptance criteria, delivered end to end.

    Best for

    A product, MVP, or integration with a clear finish line

  • Retained

    Ongoing improvements, maintenance, and security upkeep for software already in production.

    Best for

    Keeping a shipped system healthy and moving

FounderFull-Stack & Forward-Deployed Engineer

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.
