Experience

Voarnet

An aircraft maintenance application developed between 2011 and 2013 still in use to this day. It was designed to help with the whole journey of booking an overnight hangar, mechanic maintenance, aircraft checklist, manufacturer-recommended actions, etc. The project was developed using PHP, Oracle Database, and jQuery.

Database Optimization

A US-based eCommerce was providing over 400 websites and millions of products from a single MySQL database instance. I was tasked with reducing the overhead on the MySQL server, tuning some extremely heavy queries, and figuring out the proper indexing strategy for parts of the application.

Brefphp

https://bref.sh

A custom AWS Lambda Runtime that allows running PHP code using Serverless. I have contributed and worked actively on the project for a few months, studying and improving the process of building custom runtime and publishing it on all AWS regions through a single AWS CodePipeline action.

Port7777

https://port7777.com/

7777 is a standalone CLI tool written in Node.js that allows developers to seamlessly connect to an AWS RDS by establishing an SSH Tunnel on AWS Fargate. Private Keys are generated on-the-fly and discarded as soon as the tunnel is closed, keeping the connection secure and free of attacks.
The tool can navigate from a chosen RDS Cluster and figure out which VPC and Security Group should be used on which Availability Zone to improve connectivity with the RDS.
