Services

Engagements, scoped to how systems actually fail.

Every service below comes out of production work — not a capability list assembled for a website. Engagements run as full ownership: architecture, implementation, deployment, and the hardening pass afterward.

  • 01

    Real-Time Systems & Telephony

    Call routing and live distribution engines that stay correct under peak concurrency — atomic claim semantics, consistent state, no double-booking.

    Node.jsTwilioRedisPostgreSQL

    Included

    • Routing engine architecture and rewrites
    • Atomic agent-claim and queue semantics
    • Concurrency correctness under load
    • Crash-pattern diagnosis and server tuning
    • Multi-tenant / white-label readiness
  • 02

    Billing & Payments Pipelines

    Usage and per-event billing you can defend in an audit — accurate metering, reconciliation support, and a full trail behind every charge.

    StripeNode.jsSQLWebhooks

    Included

    • Per-call / per-usage metering
    • Real-time billing pipelines
    • Reconciliation and dispute tooling
    • Stripe integration and webhook verification
    • Immutable audit records
  • 03

    Internal Operations Platforms

    One place where operators actually run the business: unified CRM data, role-scoped dashboards, and metrics that load instantly at scale.

    ReactNode.jsPostgreSQLRedis

    Included

    • CRM and data-source unification
    • RBAC dashboards per role
    • Real-time KPI aggregation
    • Precomputed metrics for large datasets
    • Drill-down reporting and playback
  • 04

    Automation Engineering

    Manual daily workflows replaced with API-driven automation that runs in parallel, reports itself, and does not quietly fail.

    PythonNode.jsREST APIsSlack API

    Included

    • Carrier and third-party verification automation
    • Selenium-to-API migrations
    • Multi-instance parallel execution frameworks
    • Slack alerting for compliance and activity
    • Metric-driven rules over static schedules
  • 05

    AI Agents & Voice

    Agents that do real operational work — qualifying inbound callers, moving CRM records, and deciding when a human needs to step in.

    OpenAI APIClaude APILangChainRAG

    Included

    • Inbound voice qualification agents
    • Configurable scripting and conversational objectives
    • Live qualification-signal routing logic
    • Multi-agent orchestration across CRM, email, analytics
    • RAG over internal knowledge
  • 06

    Compliance & Security Hardening

    Regulated data handled properly: encrypted at rest, logged for audit, retained on schedule — plus a hardening pass across the existing stack.

    AES-256-GCMJWTRBACCSRF

    Included

    • PHI storage with AES-256-GCM encryption
    • Audit logging and retention policy
    • Authentication and RBAC review
    • Input validation and CSRF coverage
    • Webhook signature verification
  • 07

    Interactive Web & 3D R&D

    Frontend work with an engineering budget: GPU-aware interactive scenes and performance-tuned architecture, not decoration.

    Three.jsWebGLReactVite

    Included

    • WebGL / Three.js scenes
    • Animation pipelines and reusable frameworks
    • Performance-optimized frontend architecture
    • Design-system and component foundations
    • Modern build tooling

How engagements run

Four phases, no ceremony

Short cycles, visible progress, and no dependency on a team that does not exist.

  1. 01

    Audit

    Read the live system, reproduce the failures, and identify what is architectural versus incidental.

  2. 02

    Architecture

    Define the target design — data model, concurrency semantics, security boundaries, and rollout path.

  3. 03

    Build

    Ship in increments against production reality, with instrumentation and incident tooling from day one.

  4. 04

    Harden

    Close the security surface, tune infrastructure, document ownership, and hand over operable tooling.

Next step

Scoping starts with the failure you already know about.
