BlackVertex — Engineering practice

Systems that have to hold.

Full-stack engineering for applications, backend platforms, and secure public-facing systems. Architecture, build, deployment, and maintenance stay with one accountable engineering lead.

Capabilities

  1. 01

    Application engineering

    Web applications, portals, dashboards, and internal tools — interface to database, designed and built as one system.

  2. 02

    Backend & platform systems

    HTTP APIs, service architecture, data modeling, schema migrations, and background processing.

  3. 03

    Access & auth systems

    Authentication, session management, role- and permission-based authorization, and auditable access control.

  4. 04

    Integrations & data flows

    Third-party APIs, OAuth flows, structured imports and exports, and document pipelines between systems of record.

  5. 05

    Reliability & maintenance

    Automated test suites, deliberate deployments, documentation, and long-term maintenance agreements after launch.

  6. 06

    Standards & accessibility

    Built toward WCAG accessibility standards with performance budgets and security-conscious defaults throughout.

How the work is built

The same discipline applies to every system the practice touches, whatever its size.

  • Everything lives in version control — code, schema, and infrastructure configuration.
  • Schema changes ship as reviewed migrations, never as manual edits to a live database.
  • Automated tests cover the runtime, configuration, and the paths that carry real consequences.
  • API surfaces are documented as contracts before anything consumes them.
  • Production changes are staged first, deliberate, and reversible.

Built in practice

Systems designed, built, and operated by the studio.

  • Syncora

    syncora.dev ↗

    Context platform for AI-assisted software teams: a local-first project knowledge graph with session continuity, validation, and coding-agent integration.

  • Platform runtime

    The containerized service runtime behind the studio's client systems: authentication and role-based authorization, migration-driven persistence, and tested HTTP and configuration layers.

  • Calibrate

    A client-facing visual preference instrument: adaptive Elo-based pairing engine, config-driven test packs, and a print-ready results pipeline.

  • Intake pipeline

    The studio's own project application: serverless intake with validated submissions, structured storage, and automated dispatch.

Ways of working

Direct engagement

Fixed-scope architecture and build, followed by a maintenance agreement. One engineering lead from the first decision to production.

Subcontract & teaming

Build partner to primes, agencies, and studios that need the software half delivered — scoped, documented, and accountable.
