Java Developer at Branchspace evolving Triplake’s 40+ module monolith into independently deployable airline retailing products.

Message

At Branchspace, I work across several teams on Triplake, a modular airline retailing platform serving three airline clients. I’m designing the modularization of a 40+ module Maven monolith and have designed and built microservices and an internal SDK.

I’ve integrated airline services with booking, check-in, payment and insurance systems, and developed backend features for payments, refunds and boarding passes. Earlier, at Lufthansa, I worked on document validation and a Server-Driven UI platform; at Motorola Solutions, I worked on event-driven radio infrastructure monitoring.
