At Finlanza Ltd, I built a biometric attendance system for five construction sites and automated weekly payroll reporting with Zoho Creator and Deluge.

I also built PayrollOS, a payroll engine linked to Zoho People, and a Garage ERP system that tracks vehicles from inspection through payment. I connected Zoho CRM and Zoho Books to external financial services through secure APIs.

Previously, I built responsive React components as a Frontend Engineer (Intern) at Valos.ai and secure enterprise APIs as a Backend Developer at Techno Brain. My projects include an AWS DevOps automation suite that cut deployment time by 75%.
