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.

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.

8 Audio Profiles

From Classic vario to Thermal Hunter — choose the feedback that fits your flying style

Auto Detection

Detects takeoff and landing automatically so you never miss a flight

Flight Recording

Full GPS track with altitude, glide ratio, and FAI-standard IGC export

Privacy First

No analytics, no ads, no tracking. All data stays on your devices
