At Techcess Business Solutions (Pvt) Ltd, I lead the mobile backend API team for a multi-tenant school resource platform serving Parent and Teacher apps across 12 schools and more than 60,000 students. I designed versioned Laravel REST APIs and integrated payment gateways, with webhook callbacks and scheduled reconciliation for payment status updates.

At Olanka Travels (Pvt) Ltd, I developed integrations connecting the B2B travel platform with Zoho, Twilio, Airtable, Okta, and payment gateways. Earlier, at Asia Media Global (Pvt) Ltd, I led the backend migration of an IPTV billing platform from CodeIgniter to Laravel, including a resumable ETL pipeline and migration reconciliation checks.
