Tushar Warule

• Enterprise Framework Evolution: Architected and scaled a unified Python and Robot Framework ecosystem for the WaveLinx global IoT platform across 4 product variants (PRO, CAT, Lite, CORE); expanded coverage from UI and API to serial-level and reliability testing.

• Shift-Left DDT Implementation: Spearheaded a Data-Driven Testing (DDT) strategy utilizing Excel-based setups, batch-file triggers, and automated graphical report generation. Handed these portable suites to the development team, establishing an early-stage bug detection pipeline.

• CI/CD Build Acceptance (BAT): Refactored legacy BAT suites from static, high-maintenance code into highly portable, dynamic scripts integrated directly into the CI/CD pipeline, allowing build-to-build regression runs on any setup without code modifications.

• Sustainable Regression Design: Authored extensive regression suites structured around portability, scalability, and repeatable execution across release-by-release cycles, drastically reducing human testing overhead.

Key Engineering Projects & Impact

Dual Tech Acoustic Sensor Integration

• Challenge: Validating a complex, multi-tech occupancy sensor combining Passive Infrared (PIR) and acoustic sound technologies while isolating environmental and multi-sensor noise interference during reliability runs.

• Solution & Execution: Owned the end-to-end test planning, physical setup configuration, and Python/Robot script design. Built a highly customizable multi-config data-driven framework where manual testers could trigger deep iterative reliability cycles via a single batch file.

• Impact: Reduced manual testing efforts by 70% for all subsequent reliability and regression testing cycles.

Centralized Backup & Restore Feature

• Challenge: Scalability testing for a feature that transitioned standalone WAC (Wireless Area Controller) testing into a concurrent backup/restore process managed simultaneously by a central CORE controller.

• Solution & Execution: Engineered multi-WAC handling logic within the automation script, driving bulk device authentication via a single data sheet. Leveraged high-speed API checkpoints to instantaneously verify thousands of deep post-restore device configurations that were impossible to audit manually.

• Impact: Cut test execution time by 4 hours per release cycle and was honored with the "Game Changer Award" for technical innovation.

Multi-Controller Reliability Framework

• Solution & Impact: Migrated legacy reboot and factory-reset stability scripts into a flexible DDT architecture. Rapidly adapted this framework to support a newly introduced controller, delivering reliable, hands-off automation data critical for final product sign-off.
