Senior Software Engineer in Test

Daxko

Jun 2026 – Present

Test the Daxko Payment Cloud (DPC), the orchestration layer connecting Daxko's platforms to 8+ payment processors with a single integrated payments experience.

• Validate auth, refunds, tokenization, and hard/soft decline handling across debit, credit, ACH, Apple Pay, Google Pay, and in-person terminal transactions.
• Test payment orchestration flows between internal platforms like MMS and 8+ third-party payment processors.
• Run API and performance testing with Postman and K6 against services on AWS and Rancher-managed Kubernetes, backed by MySQL and Redis.
• Generate and maintain Playwright test coverage using Claude Code and Cursor, with CI pipelines in GitLab.

Founder & QA Tech Lead

Aperca LLC (Self-Employed)

Jun 2025 – May 2026

Built an agentic AI QA platform that turns requirements into executable tests, defects, and release signals with minimal manual handoff.

• Converted JSON and JIRA requirements into AI-generated Playwright coverage and auto-filed defects through a TypeScript CLI.
• Used Claude for requirement reasoning and failure analysis, and OpenAI Codex for test generation and refactoring.
• Designed a swappable agents/workflows/skills architecture so models and execution targets changed without platform rewrites.
• Added Playwright MCP and GitHub Actions, cutting test authoring time 60% and producing CI-ready structured outputs.

Senior QA Engineer

Dispel (concurrent with Aperca LLC)

Jun 2025 – Nov 2025

Scaled performance, security, and regression automation for secure remote-access products where reliability and compliance were non-negotiable.

• Built a K6 + Docker + Grafana/InfluxDB framework for load, stress, and spike testing across multiple products.
• Used Playwright MCP, Claude, and Copilot to cut test development time 60% while expanding regression depth.
• Added AI-assisted code review and codebase analysis, reducing regression defect escapes 35% before merge.
• Integrated OWASP ZAP and deterministic PostgreSQL test data into CI/CD for compliance-grade security validation.
• Used multi-context Playwright testing to simulate concurrent users in the same flow, validating real-time access control and session isolation.
• Built the Dispel Observability Hub to centralize uptime, SLA routing, and executive incident reporting.

Technical Lead (QA)

Cognizant Client: AT&T / DirecTV

Dec 2023 – Jun 2025

Owned fraud, payments, and PCI QA for AT&T DirecTV billing flows where release mistakes carried direct financial and compliance risk.

• Expanded payment API coverage from 65% to 92% by using GenAI to map edge cases across refunds, chargebacks, webhooks, and fraud flows.
• Cut root-cause analysis time 40% with AI-assisted stack-trace parsing and targeted regression generation.
• Ran AI-backed code reviews on payment flows to catch security gaps, PCI issues, and fraud risks before release.
• Implemented CI quality gates that blocked merges when critical payment path coverage dropped below threshold — catching a fraud-validation bypass before staging and establishing it as the team standard. Delivered zero production defects across all major launches.

Test Manager

DXC Technology Client: AT&T / DirecTV

May 2022 – Oct 2023

Led QA strategy for DirecTV streaming launches that needed faster release cycles without production fallout.

• Cut manual regression effort 70% by automating UI and API coverage for TVOD and MDU releases.
• Added Dockerized parallel execution and CI quality gates to shorten feedback loops and speed sign-off.
• Owned risk-based planning, triage, release decisions, and stakeholder reporting across multiple launch tracks.
• Delivered repeated zero-defect launches across enterprise streaming rollouts.

Automation Engineer

insightsoftware

Nov 2021 – May 2022

Automated validation for financial Excel plugins, protecting formula accuracy, data integrity, and repeatable releases.

• Built Ranorex and C# suites validating ETL accuracy — source-to-target row counts, transformation logic, formula correctness, and null/default handling.
• Dockerized test environments to reduce setup drift and make regression runs repeatable.

Software Engineer in Test

Accruent (Fortive, NYSE: FTV)

Nov 2018 – Feb 2021

Built security, performance, and regression systems that supported faster enterprise SaaS releases with lower operational risk.

• Architected CI-ready security and performance suites that strengthened release confidence for a distributed SaaS platform.
• Automated onboarding and environment setup to cut manual errors and keep regression coverage moving.
