Work Experience (6)

Provided contractor services through my own LTD, Casa4, in between other roles. The following is a list of the most notable projects, specialising in Laravel and Node.js. Involved both in team-based development and solo application building from design to deployment and maintenance.

**ElectroRent** *(Laravel, MySQL, SQLite, Bash)* As a **Backend Engineer**, I enhanced application performance by optimizing critical API areas and expanded functionality by designing and implementing new endpoints for key business features.
**Aliat Optic** *(Node.js, Serverless Framework, Lambda, DynamoDB, AWS, MySQL, Laravel, DigitalOcean)* As a **Principal Product Owner & Engineer**, I designed and built a serverless invoicing application that operated reliably in production for over 3 years with minimal maintenance, processing external FTP data via AWS Lambda and DynamoDB.
**Hurlingham Club** *(Laravel, Laravel Forge, Laravel Envoyer, MySQL, AWS, Docker)* As a **Backend and DevOps Engineer**, I orchestrated the migration of a major application to the client's own AWS infrastructure, resulting in a 40% reduction in infrastructure costs. This involved a full technology upgrade from PHP 5.5 to 8.1, provisioning new infrastructure, and establishing a modern CI/CD pipeline, ensuring zero data loss. Throughout the project, I created and presented diagrams to stakeholders to communicate the process and progress at each stage.
**TicketTailor** *(PHP, MySQL, SQLite)* As a **Backend Engineer** I worked on the API of the second largest ticketing application in Europe. Designed and implemented a testing framework using PHPUnit with automated OpenAPI validation. This improved deployment times by 35% while indreasing reliability. Also contributed by adding numerous endpoints to the client-facing API.

Owned the product roadmap by translating business requirements into actionable project features and oversaw application architecture to ensure alignment with business goals.

Led the development and launch of the MVP, defining the product vision and strategy, leveraging a team of part-time contractors and very limited resources to deliver a successful product to market.
