Adam Troxell

Available for hire

Full-Stack Engineer. Hands-On Former CTO. I build real systems.

I'm open to senior roles where I can own meaningful problems end to end — from backend and data to product and UI. I do my best work when I can ship, operate, and iterate in production.

What I Bring

Nine years in real estate technology

I spent nine years at FBS Systems (Flexmls), one of the largest MLS platforms in the country. I started in support and moved into solutions and escalation work, helping teams integrate and operate complex software. That background shows up in how I build: pragmatic, supportable, and built for real users.

Production IoT platform from zero

As CTO and sole engineer at RJ Energy Solutions, I designed and shipped an end-to-end IoT telemetry platform for commercial facilities. I owned sensor integration, data pipeline, alerting, dashboards, cloud infrastructure, and production operations. No team. No playbook. Just requirements and a blank canvas.

Pragmatic software, not clever code

I optimize for maintainability and real-world reliability. I've been the person debugging production issues under pressure, and I build accordingly — code that holds up at 2am, not just in a PR review.

Case Study: Dart Solutions Platform

Production IoT telemetry platform · RJ Energy Solutions

The Situation

RJ Energy Solutions needed real-time visibility into industrial equipment across multiple commercial sites. Existing tools required manual monitoring and couldn't coordinate across locations.

What I Built

A production IoT platform handling the full data lifecycle — from LoRaWAN sensor transmission through ChirpStack gateway management, into a FastAPI ingestion layer, stored in TimescaleDB, and surfaced through a React dashboard with role-based access and real-time alerting.

Constraints

  • Multi-tenant architecture from day one
  • Alert latency under 2 minutes end-to-end
  • LoRaWAN codec complexity across Dragino sensor types
  • 24/7 uptime on live production sites

Results

  • 50+ active sensors across 2 commercial sites
  • No missed alerts during production rollout
  • 99.9% uptime across deployment period
  • Eliminated manual equipment checks
  • Multi-tenant dashboard for multiple orgs

What I Owned

Platform architecture · Sensor integration & codec development · Real-time ingestion pipeline · Alert rule engine · React dashboards · PostgreSQL/TimescaleDB schema · ChirpStack & gateway management · OCI/Fly.io/Vercel deployment · Production monitoring & incident response · Multi-tenant data isolation
