Get in touchWhat We Do
Senior-level engineering consulting for complex backend problems, and consumer mobile apps built for Wear OS and Android.
Backend engineering and architecture consulting with 15+ years of experience across APIs, microservices, and distributed systems. Available for select engagements on a contract basis.
Wear OS and Android applications built for niche communities. We focus on tools for outdoor athletes and pilots — starting with Riser, our variometer for paragliders.
Consulting
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.
Apps
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.
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.
Every flight is recorded and logged with full stats — max altitude, distance, duration, climb rates, and glide ratio. Flights sync automatically to the companion Android app where you can review your flight history, share IGC files for competition scoring, or upload to SportsTrackLive.
Pair your XCTracer, Skydrop, or BlueFlyVario via Bluetooth — use your watch as a wrist-mounted display for your existing hardware
Stream your position to LiveTrack24 and SportsTrackLive so friends and safety contacts can follow your flight in real time
Arm from your watch face with one tap. Riser detects your flight and alerts you to start recording
Every flight logged with full stats. FAI-standard IGC export, automatic sync to companion phone app, upload to SportsTrackLive
Freeflight, Paramotor, or XC presets — or build a fully custom layout. Choose 1–4 metrics per screen with dynamic font sizing
Instant audio response with smooth display numbers. Compass heading and bearing-to-launch beacon on the bezel edge
