What I'm looking for

I'm looking to lead and build scalable full-stack platforms where I can apply application architecture, API integrations, secure payment workflows, performance optimization, and Agile team leadership.

I've spent 10+ years building and supporting scalable web applications and enterprise digital platforms, most recently as a Senior Full-Stack Developer and Team Lead at Poornam Info Vision.

I architect Drupal modules, themes, Webform components, and full-stack applications across Drupal, Laravel, WordPress, Node.js, and React. My work includes HubSpot, Sugar CRM, TrueNorth, and Microsoft Service API integrations that automate data synchronization and business workflows.

I've delivered secure PayPal and Stripe payment flows, optimized MySQL queries and indexing for high-traffic applications, and implemented authentication, role-based access control, encryption, and API security practices.

Across e-commerce, booking, healthcare, rental, finance, and CMS platforms, I lead sprint planning, estimation, code reviews, and technical delivery while mentoring teams and resolving complex production issues.
