I started on the other side of the conversation.

Portrait of Ignatius Karel

From 2019 to early 2024 I worked in airline ticketing on the Traveloka project at ATI Business Group: issuing and rescheduling tickets on Sabre, Galileo and Amadeus, handling refunds and complaints, and finally leading the ticketing team.

In 2024 I went through Hacktiv8's Full Stack JavaScript Immersive program, and in July 2024 I joined Cekat.AI as a full-stack developer. I work on its AI and CRM products.

Leading a team on the aviation side is where I learned the cross-functional delivery and mentoring I now bring to engineering.
