Consulting

15+ years of backend engineering

From greenfield builds to scaling existing systems, we bring deep hands-on experience to every engagement. Whether you need an architect for a new product, a senior engineer to embed on your team, or a technical review of your existing codebase — we've done it before and we ship.

Hall Labs provides senior-level backend engineering consulting. We've spent over a decade and a half building APIs, microservices, and production systems across the full product lifecycle — from first commit to scaling to dedicated teams.

We work best on hard problems: greenfield product builds, architecture redesigns, system migrations, and technical analysis. We're comfortable working autonomously, leading small teams, or embedding as a senior contributor on an existing team.

  • Backend Architecture — API design, microservices, event-driven systems, and infrastructure planning
  • Greenfield Development — Solo builds from zero to production, designed to scale into full team ownership
  • Technical Analysis — Codebase review, architecture assessment, and deep-dive investigation
  • AI Integration — OpenAI APIs, MCP protocol, and building AI-powered product features
  • Full Stack — Node.js, Ruby on Rails, Python, TypeScript, GraphQL, PostgreSQL, AWS, Kubernetes

Apps

Riser

A paragliding variometer for your Wear OS watch. Riser delivers real-time audio and haptic feedback for lift and sink so you can stay focused on the sky — no extra hardware, no phone in your harness, just your watch on your wrist. User Guide → · Privacy Policy →

Riser turns your watch into a precision variometer. Hear thermals through audio tones that change with your climb rate, feel lift and sink through haptic pulses, and keep your eyes on the sky instead of a screen.

Flights sync automatically to the companion Android app, where you can review stats, share IGC files for competition logging, or export to your favorite flight analysis tool.

External Vario Display

Pair your XCTracer, Skydrop, or BlueFlyVario via Bluetooth — use your watch as a wrist-mounted display for your existing hardware

Live Tracking

Stream your position to LiveTrack24 and SportsTrackLive so friends and safety contacts can follow your flight in real time

Flight Detection

Arm from your watch face with one tap. Riser detects your flight and alerts you to start recording

Flight Recording & Sharing

GPS track with IGC export. Sync to your phone, share files, or upload to SportsTrackLive

Audio & Haptic Feedback

8 audio profiles from Classic to Thermal Hunter, plus haptic vibrations — fly without looking at a screen

Privacy First
