PROFESSIONAL EXPERIENCE

Senior SDET Staples Dallas, TX Feb 2025 – Present

Architected Karate framework test suites validating 40+ REST API endpoints across 8 e-commerce microservices with schema assertions, response chaining, and data-driven scenarios catching contract regressions before downstream consumers were impacted.

Automated critical UI workflows using Playwright with Python covering checkout, payment, and account management journeys across Chromium, Firefox, and WebKit — replacing 3 hours of manual regression with 12-minute parallel runs.

Scripted Python utilities for test data generation, environment setup, and Oracle/SQL JDBC-based validation comparing API responses against database records and flagging mismatches automatically.

Configured Jenkins multi-branch pipelines triggering Karate API suites and Playwright UI tests on every pull request with Bitbucket webhook integration, Docker-containerized test runners, and Helm-deployed test infrastructure on Kubernetes.

Leveraged GitHub Copilot and Claude Code daily for generating Karate feature files, Playwright page objects, and Python assertion helpers — cutting test authoring time roughly in half while reviewing every suggestion before commit.

Monitored test environment health and post-deployment stability through Dynatrace APM traces and Kibana log dashboards, correlating failed test runs with application-level errors to accelerate root cause analysis.

SDET Michelin Remote, United States June 2023 – Dec 2024

Built Karate API test suites for internal developer portal validating environment provisioning, pipeline management, and notification endpoints with embedded SQL calls verifying PostgreSQL state directly from feature files.

Developed Playwright/Python UI automation for Angular portal covering provisioning workflows and dashboard interactions — integrated into Jenkins nightly regression with Docker-containerized execution on OpenShift clusters.

Wrote Python scripts automating test data seeding, RabbitMQ message validation, and Spring Boot actuator health checks ensuring backend services were stable before UI tests executed.

Managed Git workflows on Bitbucket with feature branching, pull request test gates, and GitOps-style promotion of test configurations across dev/staging/production namespaces using Helm charts.

Tracked flaky test patterns through Kibana log analysis and Dynatrace transaction traces — isolated 30+ timing-dependent failures caused by async RabbitMQ consumers and stabilized the suite to under 3% flakiness.

SDET DCB Bank Remote, India Jan 2021 – Jan 2023

Developed Karate framework test suites covering NEFT/RTGS/IMPS fund transfer APIs with JDBC-based Oracle SQL validations verifying transaction ledger accuracy across 500K+ daily banking operations — caught a duplicate debit edge case that had gone undetected for months.

Automated banking dashboard UI testing with Playwright and Python covering transaction history, balance displays, and compliance forms — containerized test execution in Docker on Kubernetes with Jenkins scheduled regression runs.

Built Python validation scripts cross-referencing API responses against Oracle stored procedure outputs and RabbitMQ event payloads ensuring end-to-end data consistency across partner banking integrations.

Integrated Karate and Playwright suites into Jenkins CI/CD with Bitbucket webhooks, Docker test runners, and Helm-managed test infrastructure — enforced zero-tolerance test gates blocking deployments on failure.

Contributed Spring Boot integration tests using JUnit and MockMvc validating controller logic, security filters, and exception handling alongside Karate API tests for full backend coverage.

Supported 2 RBI audit preparation cycles by providing automated test evidence, Oracle JDBC validation reports, and Dynatrace performance traces — zero compliance findings against test-owned coverage across 18 months.
