PROFESSIONAL EXPERIENCE

Shift4, Philadelphia, PA March 2021 – January 2026

Fortune 500 payment processing company serving 70,000+ merchant locations including major restaurant chains and retail businesses with $7B+ annual transaction volume

DEVOPS ENGINEER

Managed CI/CD automation and release infrastructure for enterprise POS and commerce platforms. Owned deployment pipelines for microservices architecture supporting high-volume distributed systems across restaurants, retail stores, and hospitality venues. Led infrastructure work during monolith-to-microservices migration.

●Built GitLab CI/CD framework with reusable pipeline modules for Revel POS microservices (order processing, user authentication, inventory sync, customer management) integrating k6 performance tests validating response times and Postman API checks ensuring service compatibility becoming mandatory deployment requirement across engineering teams

●Convinced upper management to adopt standardized automation by presenting deployment failure data and costs then piloting with one team before rolling out to entire Product Engineering Department (50+ engineers) during monolith-to-microservices migration creating reusable GitLab templates with Terraform infrastructure modules and Blue/Green deployment patterns used as reference across all microservices teams

●Packaged applications into Docker containers solving environment consistency problems enabling developers to spin up complete test setups (application, database, cache) quickly removing manual dependency installation across different machines

●Created automated validation gates using k6 load tests checking performance under realistic transaction volumes, Postman contract tests catching API breaking changes, and integration tests verifying service interactions preventing bad code from reaching production payment systems

●Rolled out Auth0 multi-factor authentication to enterprise merchants through automated deployment pipeline and testing strategy protecting login security for Revel POS and Shift4 payment platform without manual validation overhead

●Led Tiger Team delivering critical 3rd party integration with DoorDash under aggressive timeline building comprehensive test coverage for partner API workflows and data synchronization resulting in zero post-release issues despite compressed schedule

●Maintained production stability, managing release responsibilities across Revel POS (legacy restaurant point-of-sale) and Shift4 payment gateway (modern payment processing) without service disruptions by delegating work and setting clear team responsibilities

●Mentored junior engineers on automation framework through hands-on workshops explaining pipeline configuration, performance test setup, and API validation using real payment processing examples reducing new team member onboarding

●Designed multi-container test environments with docker-compose (application server, PostgreSQL database, Redis cache) providing consistent infrastructure across developer workstations removing manual dependency installation and configuration

Asana September 2019 – March 2021

Work management platform serving 100M+ users globally across 190 countries with tools for team collaboration and project tracking

QA AUTOMATION ENGINEER

Built automation infrastructure supporting product releases for global platforms used by millions of users across web applications, mobile apps, and API services.

●Created Page Object Model framework with Selenium WebDriver automating regression tests for core workflows (task creation, project assignment, team collaboration, notification handling) speeding up release validation for product updates deployed to 100M+ global users

●Simulated real-world network conditions using Charles Proxy (packet loss, high latency, connection drops, slow mobile networks) uncovering edge-case bugs improving Asana web and mobile apps stability for users on poor connectivity in remote regions worldwide

●Built API test suite with Postman validating contracts across microservices (task service, project service, user service, notification service) catching breaking changes during development preventing integration failures from reaching production

●Created load test scenarios simulating realistic user behavior (concurrent task creation, bulk project updates, real-time collaboration) identifying performance bottlenecks before production that would degrade user experience under actual traffic patterns

●Wrote Python automation scripts populating test databases with realistic datasets enabling developers to run full integration tests locally without manual data preparation reducing testing friction

Belazor Technologies June 2017 – September 2019

Telecommunications infrastructure provider specializing in 5G network deployment and mobile connectivity solutions

NETWORK ENGINEER

Automated testing and monitoring for next-generation mobile network infrastructure including 5G base stations, radio equipment, and operator control systems.

●Built automation scripts in Bash and Python testing connectivity between 5G base stations and remote operator systems ensuring reliable signal transmission for mobile network equipment across deployment sites

●Validated system integration between network hardware and operator infrastructure testing that mobile service worked end-to-end meeting performance specifications before activating sites for customer traffic

●Created monitoring systems tracking network health metrics (signal loss, bandwidth usage, traffic load) with automated traffic redistribution during peak hours ensuring balanced load across infrastructure and maintaining service quality for mobile subscribers

●Analyzed network performance data troubleshooting connectivity problems by understanding physical constraints (signal interference, equipment placement) and protocol behavior (tower handoffs, subscriber authentication) resolving service issues

●Automated hardware validation before installation using PIM tests and Sweep tests catching defective equipment upfront preventing costly tower climbs for equipment replacement saving crew time and reducing deployment costs through process optimization

●Worked with RF engineering crews and network operations translating technical analysis into practical improvements enhancing signal stability and reducing customer connectivity complaints
