Capabilities

Software development — end to end.

Fabs Labs is a team of senior engineers, designers, and operators who build production systems from first principles. We don't outsource the hard parts. Every layer — from the voice pipeline to the database schema to the iOS app — is written, reviewed, and operated by the same people who designed it.

01

Realtime voice & telephony

Sub-second pickup, low-latency streaming, custom voice cloning, multilingual conversation. We have the engineering to make AI sound human across Twilio, SIP, and proprietary telecom stacks — without the canned-bot uncanny valley.

02

Full-stack web platforms

Single-page apps, admin consoles, customer dashboards, B2B portals. We design the experience, build the API, write the migrations, and ship the production cluster. Typed end-to-end, observability included, no hand-offs.

03

Native mobile apps

Production iOS and macOS apps with Swift, CallKit, PushKit, WebRTC, voice pipelines and offline-first sync. Distributed via App Store and TestFlight, signed and notarised, not just toy demos.

04

AI back-office automation

We wire LLMs into actual business workflows: bookkeeping, lead intake, support triage, accounting, document understanding. Not chatbots — auditable systems with retrieval, tool-use, and human-in-the-loop where it matters.

05

Infrastructure & DevOps

Self-hosted Docker stacks, CI/CD pipelines, encrypted backups, Caddy/Cloudflare edge, monitoring and watchdog daemons. Your data lives where you choose it to live, billed by the box, not by the seat.

06

Product & engineering design

We do the discovery, write the spec, draw the flows, prototype on real data, and run the launch. Every project gets shipped with documentation, a runbook, and a path for the customer to take over the keys when they want to.

THE TECHNOLOGY BEHIND THE WORK

Stack we trust.

We don't reinvent — we orchestrate the best AI infrastructure money can buy, then wrap it in something you can actually use.
