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 Solution Architect, 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. 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 to automatically scan OpenAPI specs and validate each API endpoint, including all new additions. This significantly improved deployment times combined with strategically assigning tests to the appropriate level (unit, integration, acceptance). Also contributed by adding numerous endpoints to the client-facing API.

Led the development and launch of the MVP, leveraging a team of part-time contractors and very limited resources.

Architected and managed backend API, blockchain smart contracts and frontend integrations with 3D components

Led a team of 3-4 developers, providing technical guidance, managing the product backlog, and supervising deployments to AWS infrastructure using Docker to ensure robust and scalable operations.

↪ Technologies: Node.js, React, ThreeJS, Solidity, Hardhat, Express, Postgres, MongoDB, AWS, Docker

Architected and developed the core API and serverless infrastructure, establishing a robust and scalable foundation for all system operations.

Built a suite of internal tools, including a Vue.js reporting application for non-technical stakeholders and Laravel Nova dashboards for system monitoring, significantly improving data accessibility and operational oversight.

Also built a bespoke real-time caching system that stores processed relational MySQL data into a MongoDB database controlled and accessed by a serverless API. The purpose is to vastly increase the speed for final users down to near instant results and reduce the load on the main database.

↪ Technologies: Laravel, Laravel Nova, Laravel Vapor, AWS, SQS, VueJS, Node.js, Serverless Framework, Lambda, CLI, Bash

Engineered and led the seamless migration from NoSQL (CouchDB) to a relational database (MySQL), achieving an 11x performance increase with zero downtime or impact on the user experience. The process involved creating custom migration scripts, data normalization, and rigorous consistency checks.

↪ Technologies: Node.js, Express.js, TypeScript, CouchDB, AWS, Loopback, pm2, Angular

Designed, built, and maintained multiple large-scale applications, including a nationwide educational platform serving thousands of users and a comprehensive financial management tool, using Laravel and Vue.js.

Established a comprehensive CI/CD pipeline using Laravel Forge for DigitalOcean infrastructure, which significantly accelerated deployment cycles and improved application reliability.

↪ Technologies: Laravel, DigitalOcean, Laravel Forge, MySql, VueJS

Developed and maintained a variety of marketing applications using vanilla PHP and Symfony, delivering new features and resolving bugs.

Key contributions included implementing scalable APIs, building reusable libraries to enhance team productivity, and creating an internal client with AngularJS
