BrightInsight Indemnity Insurance Compliance DSL

Problem Space

In the insurance sector, legal compliance required that given the same answers to an indemnity insurance questionnaire, the system must produce the same result over a specified period. Traditional coding practices could not guarantee this immutable linkage between questionnaire responses and indemnity decisions while also supporting continuous development with daily releases to production.

Architecture & Patterns

  • Rules-as-data: Decoupled decision-making rules and questionnaire answers from application source code, transforming them into data managed independently of the core application logic
  • JSON-based DSL: Developed a JSON data structure that evolved into a domain-specific language, enabling underwriters to create, modify, and test insurance products by defining questions and leveraging answers from previous applications
  • Deterministic decision engine: Same inputs always produce the same outputs within the legally mandated time window — compliance assurance through time-windowed regression retesting of every previously answered questionnaire
  • Compliance-driven continuous delivery: Separation of decision logic from application code allowed daily production releases without compromising legal compliance
  • Domain expert empowerment: Non-engineering staff (underwriters) contribute directly to product development and testing without code changes
  • Cross-disciplinary collaboration: Engineers and underwriters collaborate within their expertise areas through the shared DSL

Tools & Stack

JSON, domain-specific language (DSL), CI/CD pipelines, automated regression testing

Business Outcomes

  • Compliance assurance: Guaranteed deterministic results (same inputs → same outputs) within legally mandated time windows by retesting every previously answered questionnaire
  • Continuous delivery: Engineering team maintained daily production releases without compromising legal compliance
  • Innovation velocity: Underwriters independently defined and modified insurance products without code changes, fostering rapid iteration
  • Cross-disciplinary collaboration: Engineers and underwriters contributed to product development within their expertise areas
  • Reduced engineering bottleneck: Domain experts directly created, modified, and tested products through the DSL

Regulated / Domain Context

Indemnity insurance, legal compliance (deterministic decision-making over specified periods)

Reusable Narrative Snippets

Pioneered a compliance-driven continuous delivery workflow for indemnity insurance by decoupling decision-making rules from application code into a JSON-based DSL, enabling daily production releases while guaranteeing legally mandated deterministic compliance.

Designed a data-driven decision model that transformed insurance rules and questionnaire answers into an evolving DSL, empowering underwriters to independently create, modify, and test insurance products without engineering involvement.

Ensured legal compliance by retesting every previously answered questionnaire within defined time windows, guaranteeing that the same inputs always produce the same indemnity decisions — while maintaining continuous delivery cadence.
