Experience

Nymbl Systems

06/2022 - 01/2025

Senior Software Engineer

  • To scale partner onboarding without duplicating integration code, I led a TypeScript architecture in Node.js on AWS Lambda that established reusable contracts and secure event-driven boundaries, enabling faster and safer delivery of new integrations.
  • When the organization needed a long-term integration strategy, I partnered with the Principal Architect to implement an EventBridge vendor connector model using Lambda Layers and Terraform, reducing marginal onboarding effort per vendor through a repeatable N+1 deployment pattern.
  • To secure inbound vendor communications, I implemented Cognito-based client-secret authentication and tenant-scoped credential configurations, ensuring authenticated access and safe retrieval of external platform data for webhook callers.
  • To unify inconsistent vendor payloads, I built normalization workflows that transformed source-specific data into generic EventBridge events, configuring API destinations and routing rules to persist integration data for core platform visibility.
  • When Lambda artifact constraints blocked deployment, I introduced a 'dummy.zip' strategy for Terraform packaging and pipeline validation, preventing failed deploys caused by upload limits while preserving predictable release behavior.
  • Led the high-stakes architectural migration from legacy AngularJS to Angular 21, engineering a hybrid application shell with specialized CORS authentication flows to support parallel production and beta environments.
  • To accelerate migration velocity, I developed custom AI-assisted extraction workflows (Claude skills) that automated the transition of legacy business logic into shared component libraries and standardized Entity-to-DTO patterns.
  • De-risked high-priority initiatives like the Billing module redesign by facilitating early technical discovery and surfacing architectural constraints, pivoting the team toward more sustainable implementations while coaching peers on API security.
  • Designed a modular guest access mechanism using custom Angular guards and resolvers, successfully decoupling user access from the primary authentication provider for specific workflows.
  • Architected and implemented a shared UI component library and standardized layouts, reducing front-end technical debt and enabling maintainable, repeatable workflows across the enterprise application.
  • Strengthened system integrity by securing API endpoints with Spring Security and integration tests, working closely with Security and QA teams to mitigate vulnerabilities and prevent regressions.
  • Prototyped an extensible HTML-to-PDF library using the Strategy Pattern to evaluate rendering engines, enabling maintainable generation of regulated medical forms and HIPAA-compliant documentation.
  • Architected APIs for auto-populating regulated forms and industry-standard EDI messages, collaborating on strict API contracts to ensure compliance and seamless integration with document services.
  • Translated complex product requirements into technical roadmaps and Jira-ready documentation, bridging the gap between Project Management and Engineering for streamlined execution.
  • Mentored junior and mid-level engineers in Angular best practices and code standards, fostering a culture of high-quality, type-safe development across a large-scale enterprise codebase.
