Practice two

We build AI systems the way we had to build our own.

Not a practice we started because the market got interested. We needed a production AI platform to run our own language business, we built it, and it has been processing real work under real deadlines ever since. That system is the reference for what we build for you.

The reference implementation

A production system, not a portfolio piece.

The platform Linguanational operates with Flix Translations Group LLC ingests fifteen file formats, routes them through model pipelines with glossary and memory enforcement, runs twelve automated quality checks, holds back anything that fails, and delivers through a client portal and a public API.

Every architectural decision in it was forced by something going wrong at three in the morning. That is the experience you are hiring.

Live counters, refreshed every 60 seconds. Formats include the awkward ones — bilingual CAT files, RTF, scanned PDFs — because production data is not clean.

Capabilities

Seven things we build, and the problem each one is for.

If your problem is not on this list, the discovery sprint exists precisely to find out whether it should be.

Document & workflow automation

The intake-to-output loop your staff does by hand, running unattended.

A person downloads a file, retypes it into a system, routes it for approval, and emails the result. It takes days and it is where the errors come from.

Proof

15 file formats in production, including the ones nobody supports: bilingual CAT files, RTF, IDML and scanned PDFs.

What we build

  • Ingest from email, SFTP, S3, a portal or an API — whatever you already use
  • Classification and routing rules that mirror your actual approval chain
  • Structured extraction into your database, ERP or case system
  • Human-in-the-loop checkpoints only where a human genuinely adds value

Document intelligence & OCR

Paper archives and scanned PDFs turned into structured, searchable, translatable data.

Decades of records exist only as images. Search does not reach them, reporting cannot count them, and nobody can afford to retype them.

Proof

17M+ words processed out of PDF alone, with page geometry preserved from the source rectangle rather than guessed from pixels.

What we build

  • Dual-backend OCR with automatic fallback when one engine degrades
  • Layout reconstruction that keeps tables, images and physical page size
  • Field extraction against your schema, with confidence scores
  • Output as searchable PDF, Word, or rows in your system of record

Multilingual AI systems

Language capability embedded inside your product, portal or workflow.

Off-the-shelf machine translation gets you to 'roughly understandable'. For a legal notice, a benefits letter or a safety procedure, roughly is a liability.

Proof

142 language pairs and 101 target languages running in production today.

What we build

  • Translation pipelines with your glossary, memory and style rules enforced
  • Language detection and routing for mixed-language inbound content
  • Multilingual search, chat and IVR over your own content
  • Automatic quality gates that hold a job back instead of shipping it wrong

Speech & audio AI

Recordings, calls and meetings turned into accurate, attributed, multilingual text.

Audio is the least searchable asset an organization owns, and generic transcription collapses the moment there are two speakers, an accent, or a second language.

Proof

1,388 hours of audio processed, including multi-speaker and code-switched material.

What we build

  • Transcription with speaker diarization and timecodes
  • Direct speech-to-target-language translation, not a lossy two-hop
  • Subtitle generation with reading-speed constraints
  • Redaction of names and identifiers before anything is stored

Evaluation & quality harnesses

The part every AI vendor skips: proving the output is good, continuously.

Most AI projects ship without a way to answer 'is it working?'. Six months later nobody can tell whether a model change helped or quietly broke something.

Proof

A 12-step automated QA chain runs on every production job, with a 97.6% pass rate we publish rather than assert.

What we build

  • Golden datasets built from your real, hard cases — not synthetic samples
  • Automated scoring on a defined error typology with severity weighting
  • Regression gates in CI so a model or prompt change cannot ship blind
  • Dashboards that give reviewers and executives the same number

Private & on-premise deployment

For data that cannot leave your building, your cloud, or the country.

Student records, PHI and privileged material often cannot be sent to a public model API — which is where most AI pilots die in legal review.

Proof

We run our own infrastructure rather than reselling somebody else's, so residency is a deployment choice and not a support ticket.

What we build

  • Open-weight models deployed in your VPC or on your hardware
  • US-resident processing with documented data flow
  • No client data used for training, contractually
  • Air-gapped operation where the environment requires it

Integration, APIs & webhooks

It only counts if it reaches the systems your staff already have open.

A brilliant tool nobody opens is a failed project. The work has to arrive where the work already happens.

Proof

A public API and webhook dispatcher run in production, keyed and rate-limited per client.

What we build

  • REST APIs with per-key rate limiting and audit trails
  • Webhooks for job lifecycle events into your queue or workflow tool
  • Connectors for CMS, LMS, DMS, case management and ticketing systems
  • SSO and role-based access mapped to your org chart

What usually goes wrong

Four ways AI projects fail, and what we do differently.

We have watched all four happen. Two of them happened to us before we fixed how we work.

The pilot that never ships

A demo impresses everyone, then dies in legal or security review because nobody asked where the data was allowed to go before building it.

How we handle it

We establish the data constraint in week one and pick the deployment model around it — including fully private, if that is what the material requires.

Nobody can tell whether it works

The system is live, it produces output, and there is no agreed way to say if the output is good. Six months later a model update quietly degrades it and nobody notices.

How we handle it

We build the evaluation harness before the feature, on your real hard cases, and wire it into CI as a regression gate.

It works, and nobody uses it

A separate portal staff have to remember to open. Adoption flatlines and the project is judged a failure even though the model was fine.

How we handle it

We integrate into the system your team already has open — the ERP, the case system, the LMS, the inbox — rather than adding a destination.

The 80% that costs 100%

The demo handled the clean documents. Production is scans, mixed languages, five-year-old templates and a table that spans three pages.

How we handle it

Ugly inputs are our default assumption. Our production system runs on exactly that material every day.

How an engagement runs

Fixed fee first. Big commitments only after you have seen it work.

01

Discovery sprint

2 weeks · fixed fee

We work on your real data, not a demo set. You get a written technical plan, a working prototype of the riskiest part, and a build estimate you can take to procurement. If the answer is that AI is the wrong tool here, we write that down too.

  • Technical plan
  • Prototype on your data
  • Fixed build estimate
02

Build

6–12 weeks typical

Fixed scope, milestone billing, a demo every two weeks. We build against the evaluation harness from day one, so 'done' is a measurement and not a feeling. Deployed to your infrastructure or ours.

  • Working system in your environment
  • Evaluation harness + baseline
  • Documentation and handover
03

Run

Ongoing or handover

Either we operate it under an SLA with monitoring and on-call, or your team takes it and we stay available for the first two quarters. Both are priced up front. No surprise managed-service lock-in.

  • SLA-backed operation
  • Monitoring & alerting
  • Or clean handover

Where the work runs

Our infrastructure

US-hosted, we operate it, you get an SLA. Fastest path to production.

Your cloud

Deployed into your VPC or tenancy. Your security team owns the perimeter.

On-premise / air-gapped

Open-weight models on your hardware for material that cannot leave the building.

AI solutions

Bring the process that eats the most hours.

Two weeks, fixed fee, on your real data. You leave with a technical plan, a working prototype of the risky part, and a number you can put in a budget request.
