Haball (Pvt) Ltd

Principal Software Engineer / Team Lead — B2B Payments

Haball is Pakistan's leading B2B payments and supply-chain finance platform, digitizing how corporates, distributors, and banks move money. I lead the payments team on the backend that makes it happen.

  • Leading the B2B payments team — architecture direction, code review, and mentoring, while staying hands-on in the hot paths
  • Improving core payment flows: orchestration, invoicing, and reconciliation between corporates, distributors, and banking partners
  • Designing services that are auditable and resilient — in payments, "eventually consistent" isn't a comforting phrase
