My Coverage Plan Madison, Wisconsin June 2016 to Present
Role: Senior Application Developer
Environment: Mac OS X, IntelliJ, Java, Apache Cassandra, Avail, Typescript, Javascript, WebSockets, JSON, Git, Atlassian JIRA, Atlassian Crucible, Atlassian BitBucket, Gitlab, JUnit

Design, implement, maintain, and support commercial products related to the Guruler platform, an application development platform that integrates a powerful rule engine with a high-performance server and a distributed database. The platform tightly integrates: a compiler for a strictly-typed, high-performance domain-specific language (DSL) designed to enable non-technical subject matter experts (SMEs) to develop complex rulesets and formulae; a suite of development tools, including visualization tools for understanding networks of rules and associated state variables; a customizable, asynchronous, parallel rule engine; a high-throughput, deadlock-free, asynchronous, WebSocket-enabled application server; a fully auditable, blob-oriented, distributed, multi-tenant database that automatically generates and maintains indices and data stores in accordance with query and reporting rules defined in the DSL; user-customizable data exports; data aggregation; and a skinnable modern web client. The system supports live and automated intake by multiple simultaneous users, potentially editing through disparate semantic views, and generates appropriate reports, alerts, and events. The system implements a uniform security policy that crosscuts all application layers. The main product built on the platform is the eponymous Advocus™, a customer decision support tool intended to help advocates and patients to secure healthcare benefits.

  • Architected and developed interface for dynamic generation of database tables and indices that integrate into a fully auditable, blob-oriented, distributed, multi-tenant database; developed Cassandra driver to interact with the Guruler platform.
  • Architected and developed a system that supports live and automated intake by multiple simultaneous users, potentially editing through disparate semantic views with shared state.
  • Architected and developed a data export system with an extensible export format interface which allows users to define custom-savable data exports on the client in order to export data from the system.
  • Architected and developed a concurrent data injection system with dynamically code generated client-defined data filters for injecting select data from the database into both the data export system and the data aggregation system.
  • Architected and developed a configurable concurrent data migration tool that reads targeted data from the database and passes it down a user-defined operator pipeline that transforms the data before rewriting it back to the database.
  • Architected and developed a notification system that processes email notifications to users in near real-time.
  • Developed the majority of the asynchronous, continuation-passing message processor for communicating with clients.
  • Developed centralized, server-side, continuation-passing, in-memory data store used for caching database data by all active client channels.
  • Developed client channel-specific free list cache that cooperates with the main server data store to provide shared data and channel specific data to the client.
  • Architected and developed a watchlist system for managing user worklists that tracks changes to items in the watchlist, optionally notifying users of updates via email notifications.
  • Architected and developed a templating language for configuring tenant-specific content.
  • Architected and developed a DSL for defining unit tests for subject matter expert (SME) authored rule-sets, that code generates Java test classes that can be run in the JUnit 5-based automated test runner.
  • Participated in the institutionalization of IT technical infrastructure of My Coverage Plan, Inc.
  • Participated in business development relative to the My Coverage Plan product suite.
