PHP Architect Resume Cohen Chambers PHP Architect (303) 555-0184 cohen.chambers@example.com linkedin.com/example/cohenchambers Denver, Colorado 80206 STRENGTHS Production Ownership Followed features from design through rollout, graphs, and incident follow-up; peers relied on clear judgment during difficult releases. Systems Thinking Connected caching, queues, idempotency, and back-pressure in payment workflows; one careful design prevented repeat processing under load. Clear Partnership Worked closely with mobile, QA, Product, and Design teams; concise technical notes helped decisions move forward without confusion. Practical Debugging Used traces, profiles, logs, and query plans to find bottlenecks; colleagues often called on this approach during production incidents. Quality Discipline Expanded PHPUnit coverage and code-review habits around risky changes; releases became calmer, and component owners gained confidence.

Brings hands-on depth in PHP 8.3 , modular monolith evolution, schema-driven APIs, Protobuf , gRPC, MySQL at large scale, caching , queues , and high-availability systems. Delivered end-to-end features for millions of members, from data modeling and API contracts through testing, deployment, dashboards, rollout, and incident follow-up. Partners closely with iOS, Android, QA, Product, and Design teams, communicating technical choices in clear language. Experienced with GCP migration, Kubernetes, Docker, Kafka, Google Pub/Sub, Redis, Aerospike, ClickHouse, Elasticsearch, PHPUnit, TeamCity, Prometheus, OpenTelemetry, Jaeger, payment flows, feature flags, and GDPR-aware data handling. Ready to help Northstar Social Labs strengthen member experiences and dependable backend operations. EXPERIENCE Lead PHP Architect Brightline Member Services July 2023 - Present Denver, Colorado Owns backend architecture for a consumer membership platform serving more than 8 million registered users. Guides PHP 8.3 delivery across a modular monolith, shared infrastructure, mobile APIs, monetization systems, and cloud operations while leading architecture reviews and production ownership. Reworked Protobuf and gRPC contracts across 120 high-use endpoints, adding compatibility rules and API versioning controls that protected older iOS and Android releases during staged launches. Directed GCP migration with Docker, Kubernetes, Google Pub/Sub , and Kafka, pairing lift-and-shift delivery with cloud-native service boundaries and runbooks for safer operations. Established Prometheus, OpenTelemetry, Jaeger, and liveprof instrumentation for latency, queue depth, payment failures, and database saturation, speeding diagnosis during member-impacting incidents. Shaped credits, subscriptions, and in-app purchases with idempotency keys, replay-safe event handling, and reconciliation checks across MySQL and asynchronous CPQ queues. Led design sessions, complex code reviews, postmortems, and rollout decisions with mobile engineering, QA, Product, and Design using feature flags and A/B testing controls. Principal Backend Engineer CivicPulse Digital January 2021 - June 2023 Chicago, Illinois Owned backend architecture for a high-volume social discovery product, balancing modular-monolith delivery with independently deployable services. Connected database strategy, event processing, deployment controls, testing, observability, and incident management with measurable product and reliability goals. Designed MySQL schemas, composite indexes, partitioning approaches, and query-plan improvements for tables exceeding one billion rows, using Redis and Aerospike to protect read-heavy paths. Built gRPC services with Protobuf contracts and Kafka event pipelines for mobile actions, documenting failure modes , back-pressure , retries, and idempotent processing for partner teams. Implemented Kubernetes deployment patterns through TeamCity and GitHub Enterprise , adding health checks, rollback procedures, resource policies, and release verification. Expanded PHPUnit unit and functional coverage with soft-mocks around payment, subscription, and notification integrations, reducing regression risk during monolith changes. Coordinated incident response for backend and monetization issues, tracking postmortem actions and presenting service health, business metrics , and rollout results to engineering leadership. Senior PHP Engineer HarborPeak Commerce October 2017 - December 2020 Raleigh, North Carolina Delivered server-side capabilities for a consumer commerce platform spanning web, mobile, billing, entitlements, search, and asynchronous event processing. Helped a six-engineer backend group evolve a large monolith without losing compatibility or release confidence. Isolated billing, entitlement, and account capabilities behind documented API boundaries, preserving compatibility across multiple mobile client versions during monolith evolution. Modeled subscription renewals, credit grants, refunds, and purchase callbacks with transactional safeguards and idempotent handlers for reliable payment reconciliation. Tuned query plans , indexes, cache lifetimes, and queue consumers after profiling production bottlenecks, improving consistency across catalog and member activity paths. Introduced PHPUnit functional suites and peer-review checklists covering schema, migrations, observability, and rollback concerns, strengthening delivery quality across the backend group. Partnered with QA , mobile developers, Product , and Design to validate device behavior end to end, document technical approaches, and monitor feature performance after release. PHP Backend Engineer Redwood Interactive July 2014 - September 2017 Portland, Oregon Built and maintained PHP APIs for a mobile-first consumer application, translating product needs into business logic, MySQL models, cache strategies, queue workflows, and testable services. Supported release quality across backend, mobile, QA, and operations teams. Implemented API versioning and response compatibility practices for Android and iOS clients, including graceful handling of long-tail app versions and safer staged releases. Developed queue-backed workflows for notifications, account changes, and purchase events with Kafka and Redis, documenting retry limits, failure modes , and duplicate-message protection. Added PHPUnit unit and functional tests for account, entitlement, and payment scenarios, improving release confidence across mobile and backend dependencies. Used Elasticsearch and query analysis to resolve slow member-search and activity-feed paths, pairing application profiling with index changes and targeted cache invalidation. Created deployment and monitoring improvements with Docker , TeamCity , Prometheus, and operational dashboards, giving engineers clearer rollout and incident signals. PHP Developer SignalForge Software May 2011 - June 2014 Salt Lake City, Utah Developed PHP backend modules for consumer web applications, progressing from feature delivery into independent ownership of account, profile, and transaction workflows. Built foundational experience in MySQL design, APIs, caching, testing, code review , releases, and production support. Designed MySQL tables, foreign keys, indexes, and migration scripts for growing datasets, reviewing query plans to prevent avoidable production bottlenecks. Built JSON APIs and client-server integrations consumed by early mobile applications, documenting contracts and validating edge cases with QA before release. Added Redis and Memcached caching for profile and configuration data, defining expiration and invalidation rules that preserved freshness. Wrote PHPUnit tests, participated in peer code reviews, and improved shared coding conventions across a custom PHP framework used by multiple product teams. Supported production releases and incident investigations by reviewing logs, reproducing failures, communicating findings, and converting recurring issues into monitoring work. PROJECTS GCP Monetization Migration 2025 Moved payment and subscription workloads from legacy hosting into GCP using Docker, Kubernetes, Google Pub/Sub, and Kafka. Added reconciliation, dashboards, rollout controls, and operational runbooks. Billion-Row Data Optimization 2023 Reshaped MySQL access for large activity tables through schema changes, indexing, partitioning, query-plan analysis, Redis caching, and Aerospike read protection. Mobile API Compatibility Program 2020 Created Protobuf and gRPC contract practices that supported long-tail iOS and Android versions, clearer release testing, safer rollout decisions, and dependable client-server communication.
