Led design and operation of a large-scale multi-environment platform on AWS ECS — spinning up parallel dev, test, staging, integration, and production environments for a suite of backend services — significantly accelerating release velocity and enabling safe, isolated feature validation at scale. Architected and rolled out an API Gateway layer across all cloud environments, unifying routing, authentication, and traffic control for a distributed set of backend services behind a single, consistent edge. Built a mature CI/CD foundation with GitHub Actions, including reusable notification workflows, automated release/hotfix branch reconciliation, deployment-status alerting, and synthetic-test gating — reducing manual release overhead and improving deployment confidence. Drove a security-hardening initiative across the entire CI/CD fleet, migrating from statically-credentialed managed runners to self-hosted private runners with OIDC-based role assumption, eliminating long-lived cloud secrets from every workflow in the organization. Designed and implemented an automated nightly database refresh system with DNS-based endpoint rotation, cluster lifecycle management, post-restore migration orchestration, and zero-touch service redeployment — giving engineering teams daily production-like data with no manual intervention. Integrated database migrations into the containerized deployment pipeline with deployment-blocking on failure and rich migration failure/timeout logging, preventing corrupted environments from reaching production and drastically improving the debuggability of schema changes. Engineered a full observability stack using OpenTelemetry across microservices and background workers, including auto-instrumentation, distributed trace and log enrichment with domain context, a columnar analytics store for span data, and a custom collector configuration tailored to the business domain. Built a resilient notification worker service from scratch, including health checks across databases, caches, secret stores, and messaging layers, deployed as a first-class service across all environments. Delivered end-to-end orchestration for a web-crawling platform combining ECS, a workflow orchestration engine, browser automation, a FastAPI-based control plane, distributed coordination via Redis, and S3-backed artifact pipelines — supported by a custom deployment workflow with change detection and security scanning. Hardened identity and secrets management platform-wide by integrating machine-to-machine authentication for service-to-service credential loading, extending an internal secrets API with paginated and wildcard access patterns, and introducing a feature-flag SDK for runtime configurability. Built a serverless bridge between cloud monitoring webhooks and team chat channels, tightening the feedback loop between production alerts and on-call response. Refactored core multi-tenant API surfaces to improve data-boundary correctness, request validation, and computed-field handling, reducing a class of tenant-data consistency bugs.

Led development and successful launch of a robust Django and Angular 8 web application, elevating user experience and performance, while leading the migration from legacy Perl to modern Django frameworks. Orchestrated a complex system migration from Perl-based, on-premises servers to a scalable, cloud-based architecture on Azure — enhancing system reliability and operational efficiency. Pioneered integration of financial data from FactSet, crafting a sophisticated subscription management system and transitioning from WooCommerce to a Stripe payment solution, streamlining revenue channels. Designed and implemented a comprehensive data analysis strategy, ensuring seamless data migration to MongoDB cloud servers, which significantly improved data accessibility and integrity. Played a pivotal role in strategic planning and future-proofing of application development, focusing on cloud-centric designs and architectures to foster innovation and agility. Championed DevOps culture by building a resilient infrastructure using Kubernetes, Helm, Terraform, and GitHub Actions on Azure and DigitalOcean, leading to a more agile and automated CI/CD pipeline. Demonstrated expertise in containerization with Docker, enabling consistent deployment of Python scripts, Django applications, and ASP.NET MVC solutions across diverse environments.

Integrated internal tools across disparate servers and languages into a single unified platform. Owned the full project lifecycle — from requirements gathering through implementation — leading a team of 4 engineers under Scrum and acting as the liaison between PMs and developers. Consistently delivered high-quality, scalable, and testable components on schedule, meeting Amazon's engineering standards.

Designed, built, and deployed a messaging system integrating Microsoft Dynamics, mobile apps, and web dashboards — receiving triggers from CRM and delivering messages via email, SMS, push notifications, and dashboards. Led a team formed specifically to rapidly integrate the messaging system with adjacent internal components. Built supporting tooling in Java and Node.js, primarily for logging and operational visibility.
