What we did

Together with our US partner BigSafari and Resilient Community, we build patient–therapist matching around licensing, clinical discipline, hospital credentials, distance and workload. Coordinators and therapists control assignment and acceptance. Our work also extends to AI-assisted clinical documentation and patient-facing tools.

Capabilities

  • Patient matching
  • Care coordination
  • Clinical workflows

What we did

After we took ownership of PDFPro, revenue grew by 100%+ within one year. We rebuilt the account experience on a serverless architecture, connected billing and entitlements, and handled the migration from FastSpring to Stripe. Monitoring and operational improvements support the product beyond launch.

Capabilities

  • Serverless
  • Billing
  • Customer experience

Property valuation · Applied AI

Less administration. More judgment.

Atlas

Key software in a bank-critical flow: the property valuations behind mortgage lending, from branch request and evaluator assignment to review and delivery.

What we did

A mortgage can’t move forward without a property valuation. Atlas runs that flow for OTP Nekretnine: branch requests, evaluator assignment, SLA tracking and payment matching. AI extracts valuation data from evaluators’ spreadsheets; people review the results and stay in control.

Capabilities

  • Workflow engineering
  • AI extraction
  • Human review

Bitcoin L2 · Core protocol engineering

We built Arch’s core blockchain technology in Rust: a custom Bitcoin L2 with a smart-contract processing engine.

What we did

Capabilities

  • Rust
  • Bitcoin L2
  • Smart contracts
