Work History
Senior Software Engineer
Wunderkind
06.2021 - Current
- Led performance testing for high-traffic marketing campaign products (Python/Locust) for Black Friday & Cyber Monday (2021–2024), ensuring stability under peak loads, earning company-wide recognition in 2023 and delivering the smoothest BFCM event in 2024 with minimal service disruptions.
- Implemented a Quality Watch Tower & Dynamic Scoring by building a test metrics dashboard (Elasticsearch-Kibana) and introducing Elo/Glicko-based dynamic quality scoring for repositories, providing real-time insights into pass/fail rates, flaky test detection, and uncertainty metrics while shifting testing left by penalizing late-stage failures and rewarding early detection.
- Prototyped an AI-Driven Test Analysis System by experimenting with RAG, LLM, and NER methods to autonomously parse fuzz, contract, and load test results, aiming to auto-detect critical bugs and anomalies early in the pipeline.
- Implemented a dynamic testing (fuzzing) framework targeting critical microservices and APIs, identifying previously undiscovered defects and hardening service resilience under edge-case inputs.
- Engineered a robust ESP & SMS provider monitoring system that continuously scans for outages among critical ESP and SMS providers; upon detecting an issue, it automatically alerts the relevant messaging teams and stakeholders, proactively preventing mini-incidents and eliminating last-minute escalation threads like “why did sends drop?”
- Conducted rigorous load tests and delivered actionable recommendations to curb over-provisioning—optimizing GCP resource allocation using performance test data (Grafana, GCP) and saving tens of thousands of dollars monthly while consistently meeting SLA requirements.
- Architected and maintained automated solutions across load testing (Locust, Python, k6), API & backend testing (Python, Pytest, gRPC), and UI/front-end testing (Playwright, Cypress, JavaScript).
Senior Software Test Engineer & Team Lead
TwoSix Labs Inc.
06.2017 - 06.2021
- Led and managed a team of SDETs responsible for test automation and validation of DoD cyber defense programs (Plan X/IKE)
- Developed automated tests for SIEM integration with DoD platforms, ensuring seamless integration and validating the accuracy of animated network visualizations rendered via HTML5 Canvas.
- Owned the end-to-end test automation roadmap, collaborating with senior leadership to define quality goals, test coverage strategies, and release validation processes
- Built and maintained scalable test environments in AWS by leveraging EC2 auto-provisioning via Boto3, Lambda functions for automated environment scaling, and S3 versioning for artifact management—accelerating test environment provisioning, reducing manual intervention, and streamlining release cycles for faster, more reliable deployments.
- Led the transition from Bash-scripted Jenkins pipelines to Groovy, significantly expediting the process of updating, adding new jobs, and debugging failures resulting in increased team velocity.
- Leveraged NETM to simulate variable network degradation on base, rigorously testing system resiliency under real-world conditions and informing targeted performance optimizations.
- Refactored test automation frameworks by transitioning from an unstructured approach to a Page Object Model built on SOLID principles empowering test engineers to create tests more efficiently and reducing the frequency of breakages.
Quality Assurance Engineer
Squires Group
05.2016 - 06.2017
- Developed a company-wide automated test framework from the ground up, significantly increasing coverage, execution frequency, and efficiency.
- Integrated automated tests into Jenkins CI/CD pipelines, creating a near real-time feedback loop that empowered developers to swiftly identify and resolve issues—reducing debugging time and accelerating release cycles, ultimately enhancing code quality and boosting team productivity.
- Coordinated with UI/UX teams to influence design based on usability testing insights
