Sole engineering owner of a high-revenue backend platform. Designed, shipped, and operated Node.js services, automation workflows, queues, and the AWS infrastructure they run on, end to end.

• ·Sole engineering owner of the high-revenue backend platform - ran every system end to end across design, implementation, CI/CD, deploys, observability, and on-call.
• ·Designed and built a custom multi-gateway payment platform routing across major payment gateways, with product and upsell management, subscriptions, customer vaults, and multi-domain storefronts.
• ·Built the supporting payments infrastructure - inbound IPN handling, outbound webhooks, transaction reporting, and a unified REST API used by every internal product.
• ·Migrated the Node.js services to AWS ECS Fargate, defined the full infrastructure as code in Pulumi, and replaced manual deploys with GitHub Actions pipelines.
• ·Improved reliability across the platform with structured logging, dashboards, and alerts on CloudWatch; introduced background jobs and queues (SQS, BullMQ) to handle traffic spikes and process heavy work asynchronously.
• ·Delivered production integrations with payment, communication, and email providers using idempotent retries and explicit error handling so failures stayed contained.

Earlier phase on the same anonymized platform. Laravel and Node, 50+ repos, broader IC + lead remit across delivery, cloud infrastructure, CI/CD, and security.

• ·Led delivery and code review across 50+ repositories spanning Laravel, Vue, React, Node.js, and Docker.
• ·Built and operated cloud infrastructure across multiple providers (servers, domains, TLS) and edge security via Cloudflare.
• ·Set up CI/CD pipelines on Bitbucket Pipelines, automated support workflows, and integrated transactional email providers.
• ·Strengthened security with DDoS mitigation (Crowdsec) and ran a multi-database stack - MySQL, Redis, MongoDB, SQLite.

Founded a small agency delivering custom web applications end to end for international clients, mockups through production.

• ·Led end-to-end delivery of client projects worldwide - owned technical planning, architecture, and execution; matched solutions to client requirements.
• ·Built custom web applications with jQuery, WordPress, and pre-framework JavaScript. This is where I learned to ship.
• ·Coordinated international teams and clients across multiple time zones; refined remote dev workflows that I still use.

Freelance web developer on Upwork (then oDesk) and Freelancer.com. Clients across Spain, Singapore, Germany, Brazil, the United States, and Australia.
