Senior SDET Engineer
Memorial Sloan Kettering
New York, New York
01.2024 - Current
- Executed proof of concept for UiPath Test Suite, assessing low-code automation for enterprise regression.
- Designed reusable workflows, selectors, object repositories, and exception handling protocols.
- Automated UI workflows utilizing Modern UI Automation, Orchestrator queues, and Recorder-based scripts.
- Established cross-browser testing strategy in UiPath, identifying execution limitations for high-scale environments.
- Implemented Playwright automation framework with MCP Server to enable event-based and pipeline reporting across UI and API tests.
- Created MCP notification handlers to trigger MS Teams and Outlook alerts with execution summary and failure details.
- Integrated MCP with GitHub Actions, automating real-time execution status updates to communication channels.
- Developed custom Playwright and MCP JavaScript modules to extract run metadata for comprehensive reporting.
- Developed automation using WebdriverIO (JavaScript) + Page Object Model, including reusable utilities and selector abstraction.
- Executed suites on BrowserStack
- Used Grafana K6 to simulate performance workloads for UI + API flows with ramp-up patterns, staged virtual users, SLA thresholds, and error-rate alerts.
- Integrated K6 into GitHub Actions for scheduled nightly and weekly performance runs.
- Generated analytics dashboards measuring response time, p95, p99 latency, throughput, failure rate, and VU utilization.
- Executed concurrent user loads exceeding 1000 VUs, validating system readiness under peak volume.
- Performed end-to-end validation of imaging workflows involving copy, pull, and push operations across AWS ECS workloads, ensuring reliability and performance at scale.
- Tested automation workflows across multiple ECS task configurations by varying vCPU and memory allocations to benchmark resource utilization and identify optimal deployment settings.
- Evaluated SMB vs S3 storage protocols for image ingest, retrieval, and transfer operations, comparing throughput, latency, and error-rate trends under different load conditions.
- Executed testing with different image file sizes (small, medium, large, and XL), validating stability of ingestion pipelines and detecting performance bottlenecks for large payloads.
- Verified container logs, storage telemetry, and S3 event triggers to ensure seamless connectivity between compute, storage, and workflow orchestration layers.
- Coordinated with DevOps and Platform teams to tune ECS task definitions and autoscaling limits based on test output, contributing to improved image-processing SLA compliance.
