Senior Software Engineer at Waystar

January 1, 2023 - Present

Led the redesign of a healthcare facing distributed system that orchestrates prior authorization and eligibility checks via scalable APIs, reducing timeouts caused by slow downstream dependencies. Built idempotent request flows around webhook style events to prevent duplicate updates during retries, improving data consistency across order authorization state transitions. Partnered with product and clinical ops to translate requirements into API contracts applying separation of concerns and SOLID principles to keep domain logic testable and maintainable. Implemented production monitoring and alert tuning for API latency and error rate spikes, cutting noisy pages by isolating noisy failure modes and improving signal quality. Improved reliability of integration points by adding resilient retry backoff and circuit breaking patterns for flaky third party services decreasing incident frequency for critical workflows. Developed an automated testing strategy spanning unit, integration and cont

Software Engineer at iTransition

January 1, 2021 - December 1, 2022

Delivered backend features for customer and billing workflows using REST API design, with careful API versioning and backward compatible migrations to avoid breaking client integrations. Built and maintained UI to API integration for admin dashboards in React, addressing permission errors and reducing support escalations caused by inconsistent authorization states. Refactored a legacy service to apply SOLID and separation of concerns, isolating data access from business rules so changes could be tested with confidence. Improved reliability of asynchronous data syncs by adding retry logic, dead letter handling and data quality validation, reducing cases of missing records. Wrote integration tests for critical endpoints and contract checks for key requests strengthening automated testing and catching regressions before release. Debugged production defects tied to concurrency issues by reproducing race conditions then adding idempotency and locking strategies to stabilize state transition

Software Developer at MojoTech

January 1, 2015 - December 1, 2017

Implemented core web features in React by translating UI requirements into client requests against a REST API, then verified behavior with local and staging tests. Worked on a small service backed by PostgreSQL, writing SQL queries and adding input validation to prevent bad data from breaking downstream reports. Assisted with debugging intermittent API failures by tracing requests through logs identifying a serialization bug and coordinating a fix with the backend team. Created initial unit tests and basic integration checks for new endpoints, improving coverage for frequently used flows and reducing manual verification time. Delivered a production fix that reduced failed form submissions by implementing safer request handling and clearer error responses.
